The airside environment is one of the most hazardous vehicle operating environments in any industry. Aircraft are moving — often under their own power and in ways that are difficult to predict from ground level. Jet blast and propeller wash create invisible but lethal hazards. Runways, taxiways and aprons intersect at complex angles defined by markings that are unlike anything a driver encounters on the public road network. Radio communications between vehicles, ground handlers and air traffic control must be understood and used correctly. And the consequences of a collision between a vehicle and an aircraft — or of a vehicle incursion onto an active runway — are catastrophic.

The Airside Vehicle Driver’s Permit is the mechanism through which aerodrome operators demonstrate that every person driving a vehicle on the airside area of their aerodrome understands those hazards, has been trained to operate safely in the airside environment, and has been assessed as competent to hold a permit. The permit is not a formality. It is the documented conclusion of a training and assessment process that determines whether a person is safe to operate in an environment where an error of judgement or a moment of inattention can destroy an aircraft and kill people.

Aerospace and Aviation Consulting Services (AACS) designs and delivers Airside Vehicle Driver’s Permit courses for aerodrome operators, ground handling companies, airport tenants, maintenance organisations and any other organisation whose personnel require airside driving access. We also design AVDP scheme frameworks — the policies, procedures, permit records and renewal systems that enable aerodrome operators to manage airside vehicle access in compliance with CAP 168 and the specific requirements of their aerodrome licence. Every course and scheme we produce is calibrated to the specific aerodrome environment, its layout, its traffic patterns and its local procedures.

Why Airside Vehicle Driver Training Matters

Vehicle incursions onto active runways and taxiways are among the most serious safety events recorded at aerodromes worldwide. The ICAO and UK CAA runway incursion classification system records hundreds of incursions annually at UK aerodromes — a significant proportion of them involving vehicles rather than aircraft. When a vehicle enters an active runway without clearance, the consequences depend entirely on chance: whether an aircraft happens to be using that runway at that moment, and at what speed. The physics of an aircraft-vehicle collision at take-off or landing speed leave no margin for error.

Beyond the runway incursion risk, the airside environment generates a continuous range of vehicle-related hazards: vehicles striking aircraft on stands, ground support equipment damaging landing gear or fuselage, fuel bowsers operating near ignition sources, baggage tugs creating pedestrian strike risk, and vehicles failing to hold position at mandatory instruction signs. Each of these hazard categories has an established accident and incident record. Each is preventable through proper training.

The Regulatory Framework

The requirement for airside vehicle drivers to hold a valid permit and to have received appropriate training is embedded in the UK aerodrome licensing and regulatory framework. Aerodrome operators are responsible for ensuring that all persons driving vehicles on the airside area are appropriately trained, assessed and permitted — and that the permit scheme is maintained, records are kept, and renewals are managed.

AACS designs AVDP courses that meet and, where the aerodrome’s specific environment warrants it, exceed the CAP 642 training content standard. Every course is reviewed against the applicable aerodrome licence conditions and any aerodrome-specific vehicle control procedures specified in the Aerodrome Manual before training content is finalised.

AVDP Course Content

The Airside Vehicle Driver’s Permit course must equip participants with a complete and accurate understanding of the airside environment, its hazards, its rules and the procedures they must follow to operate safely within it. Generic road safety training is not a substitute — the airside environment has its own markings, its own communication requirements, its own right-of-way rules and its own unique hazards that have no equivalent on the public highway. AACS designs course content that covers each of these dimensions fully, calibrated to the specific aerodrome where the permit will be used.

Assessment & Permit Issue

Theoretical Knowledge Assessment

The theoretical knowledge assessment tests participants’ understanding of the AVDP course content before the practical assessment is undertaken. The assessment is designed to verify that participants have genuinely understood the material — not simply that they can recall the sequence of slides. AACS designs theoretical assessments with questions calibrated to the specific aerodrome: its layout, its specific holding points, its local procedures and the ATC frequencies applicable at that aerodrome.

Theoretical assessment features designed by AACS include:

• Question bank development calibrated to the specific aerodrome environment — layout, markings, signage, local procedures and emergency plan
• Pass mark set at the standard required to demonstrate genuine safety competence — not a minimum that can be achieved by partial understanding
• Failed assessment protocol — mandatory additional instruction and re-assessment before permit consideration; a driver who does not understand the rules is not issued a permit
• Assessment record format — documenting the assessment result, date, assessor and any remedial action, in a format suitable for aerodrome permit record keeping
• Version control — assessment question bank updated when aerodrome procedures change, new aircraft types are introduced or AVDP scheme requirements are revised

Practical Airside Assessment

The practical assessment verifies that participants can apply their theoretical knowledge in the actual airside environment. No amount of classroom or online training fully prepares a driver for the experience of operating on an active aerodrome — the radio environment, the pressure of ATC instructions, the visual challenge of reading markings and signs from a vehicle at ground level, and the experience of aircraft moving in proximity. The practical assessment must test all of these dimensions before a permit is issued.

Practical assessment elements designed by AACS include:

• Escorted airside familiarisation — supervised initial familiarisation with the aerodrome layout, holding points, access routes and vehicle rules before assessment begins
• Demonstrated radio communication — the candidate requests and receives ATC instructions, acknowledges clearances and reports position correctly under assessment conditions
• Holding point recognition — the candidate correctly identifies and holds at the appropriate holding points without prompting
• Aircraft proximity assessment — the candidate demonstrates correct behaviour when aircraft are taxiing or operating in the vicinity — correct distance, correct speed, correct radio awareness
• Emergency scenario response — the candidate is presented with a simulated emergency condition (crash alarm, LVO promulgation, disabled vehicle) and must respond correctly
• FOD inspection — the candidate correctly conducts a pre-airside vehicle check and identifies any simulated FOD condition
• Practical assessment record — a structured record of the assessment outcome against each element, with the assessor’s signature and date, forming part of the permit record

Permit Issue, Records & Renewal

The AVDP permit is a controlled document. Its issue, the conditions attached to it, the areas of the aerodrome it covers, the vehicle types it authorises, and its renewal date must all be recorded and managed by the aerodrome operator. An AVDP scheme that issues permits without maintaining adequate records, that allows permits to expire without renewal training, or that does not control the return of permits when an individual’s airside access requirement ceases is a compliance failure and a safety risk.

AACS designs AVDP permit scheme management frameworks that enable aerodrome operators to administer their permit scheme in compliance with CAP 168 requirements:

• Permit document design — permit card or certificate format showing the permit holder’s details, approved areas, vehicle categories, issue date, expiry date and any conditions or endorsements
• Permit register design — database or record format enabling the aerodrome operator to identify all currently valid permits, their holders, their expiry dates and their authorised access scope at any time
• Renewal system design — renewal interval policy (typically annual or biennial depending on aerodrome requirements), renewal notice procedures and lapsed permit management
• Renewal training programme — a structured refresher course for permit renewal that updates holders on any changes to aerodrome procedures, new hazards, safety data from the preceding permit period and any regulatory changes
• Visitor and contractor temporary permit framework — a managed process for issuing time-limited permits to contractors and visitors requiring short-term airside access, with appropriate supervision requirements
• Permit withdrawal procedure — the process for suspending or revoking a permit following a safety violation, a serious near miss or a change in the permit holder’s role or access requirement

AVDP Scheme Design for Aerodrome Operators

Aerodrome operators are responsible for their AVDP scheme in its entirety — not just for the training course that sits within it. The scheme must address who requires a permit, what categories of permit exist (full permit, escorted access, temporary contractor access), what training and assessment standard applies to each category, how the scheme is administered and recorded, and how compliance with the scheme is monitored and enforced. AACS designs complete AVDP scheme frameworks for aerodrome operators — covering scheme policy, training content, assessment standards, permit documentation, records management and scheme review.

AVDP scheme design services provided by AACS include:

• AVDP scheme policy development — who requires a permit, access categories, permit conditions, scheme governance and accountability structure
• Training standard specification — course content requirements for each permit category, minimum training hours and delivery method
• Assessment standard specification — theoretical and practical assessment criteria, pass standards and failed assessment management
• Course material development — slides, participant handbooks, aerodrome-specific diagrams, marking and sign recognition references and assessment question banks
• Facilitator guide development — enabling the aerodrome operator’s own personnel to deliver the AVDP course consistently and to the required standard
• Permit document and register design — permit format, record fields and register management procedures
• Renewal and continuation training framework — renewal intervals, refresher content and lapsed permit procedures
• Contractor and visitor access framework — temporary permit procedures, escort requirements and contractor briefing content
• AVDP scheme documentation for the Aerodrome Manual — the scheme description for inclusion in the AM in the format required by CAP 168
• CAA oversight preparation — ensuring the scheme and its records will withstand scrutiny at aerodrome licence renewal and authority oversight

Specialist AVDP Course Variants

Low Visibility Operations — Enhanced AVDP

Aerodromes that conduct CAT II and CAT III instrument approach operations impose significantly more restrictive vehicle movement conditions during low visibility periods — with enhanced holding requirements, additional vehicle movement restrictions and specific radio procedures that do not apply in normal visibility conditions. Personnel who operate vehicles on the manoeuvring area during LVO must receive enhanced training in LVO-specific procedures. AACS designs and delivers enhanced AVDP training modules specifically for personnel who may operate during LVO conditions.

Enhanced LVO AVDP training covers:

• LVO categories and their trigger conditions — RVR minima for LVO to be declared; the promulgation system through which vehicle drivers are notified
• Enhanced holding point requirements in LVO — the Cat II/III holding points and their specific rules; the difference between normal and LVO holding positions
• Vehicle movement restrictions in LVO — which vehicles may move, on which areas, and under what ATC clearance during each LVO category
• Radio discipline in LVO — enhanced read-back requirements; maintaining continuous radio watch; reporting vehicle positions more frequently
• Actions if communications are lost during LVO — the specific procedures when radio contact is lost during a Cat II/III operation

Construction & Engineering Contractor AVDP

Construction and engineering contractors working airside present a specific vehicle safety challenge. Their personnel are typically unfamiliar with the aerodrome environment, they operate specialist plant and heavy machinery that has different clearance requirements from standard ground support vehicles, and their work frequently takes them close to active operational areas. AACS designs specialist AVDP training for construction and engineering contractors that addresses the specific hazards and procedures of the construction airside environment alongside the standard AVDP content.

Construction contractor AVDP additional content covers:

• Working near active areas — the specific restrictions on construction activity near runways and taxiways that remain in use; clearance distances and buffer zone requirements
• Plant and machinery airside — the specific procedures for moving heavy plant, cranes and oversized equipment airside; height clearance considerations for aircraft operations
• Work area demarcation — how construction areas are notated in the AIP and NOTAM system; the contractor’s responsibilities for keeping the work area clearly defined
• Infill and surface works near active runways — FOD prevention in construction activities; compaction equipment and debris management
• Night and low visibility construction operations — additional hazard identification for construction activities outside normal hours or in reduced visibility

Emergency Services AVDP

Police, fire and rescue services operating airside carry AVDP requirements but also have emergency access needs that differ from routine vehicle operations. Emergency vehicle access to aircraft in distress, to a runway or taxiway incident, or to a perimeter security event must be as rapid as possible — while remaining safe in the airside environment. AACS designs AVDP training for airside emergency services personnel that covers standard AVDP content alongside the specific procedures for emergency access, ATC communication during emergencies and coordination with the aerodrome emergency plan.

Refresher & Renewal AVDP Training

Permit renewal is not simply an administrative process. The renewal training session is the opportunity to update permit holders on changes to the aerodrome’s procedures, to review safety performance data from the preceding permit period, to address any recurring near miss themes identified in the safety reporting system, and to reinforce the aspects of AVDP knowledge that erosion of practice or habit formation may have degraded since the previous training. AACS designs renewal training programmes that are substantive and operationally relevant — not a shortened repeat of the initial course.

Renewal AVDP training designed by AACS covers:

• Review of any changes to aerodrome procedures, markings, signage or layout since the previous permit period
• Safety data review — vehicle-related incidents, near misses and safety observations from the preceding period, with structured discussion of causal factors and lessons learned
• Regulatory update — any changes to CAP 168, CAP 642 or the aerodrome’s own vehicle control procedures
• Reinstatement of core knowledge — targeted review of the areas most prone to knowledge erosion: LVO procedures, emergency actions and radio communication standards
• Practical re-assessment — a practical check of airside driving competence, not simply a theoretical test

Why AACS for Airside Vehicle Driver Training

Grounded in the Operational Airside Environment

AACS AVDP training is designed by advisors with direct experience of aerodrome operations and the airside environment — not by road safety trainers who have applied generic driver training principles to an airport context. We understand the layout and operational rhythm of working aerodromes, the pressure of ATC radio communication for unfamiliar drivers, the specific hazards of jet blast and propeller wash at close quarters, and the Human Factors dimensions of airside vehicle operations: the complacency of experienced drivers who have operated airside for years without incident, and the anxiety of new permit holders learning the environment for the first time.

Calibrated to the Specific Aerodrome

No two aerodromes are the same. The layout, the runway and taxiway designations, the holding points, the specific local procedures, the traffic pattern and the mix of aircraft types all vary. AACS does not deliver a generic AVDP course and leave it to participants to translate it to the specific aerodrome where they will drive. Every course we design is built around the specific aerodrome: its diagrams, its markings, its ATC frequencies, its local procedures and the specific hazard hotspots that the aerodrome operator has identified through its safety management system.

Full Scheme Design Capability

AACS provides not only the training course but the complete AVDP scheme framework that aerodrome operators need to manage airside vehicle access in compliance with CAP 168. We design the permit documentation, the training standard, the assessment criteria, the renewal framework and the scheme documentation for the Aerodrome Manual — giving aerodrome operators a complete, ready-to-implement scheme rather than a training course that they must then build a scheme around.

Aligned With CAP 168 & CAP 642

Every AACS AVDP course and scheme is designed against the current version of CAP 168 and CAP 642 — the primary UK CAA references for aerodrome licensing and airside safety management. We monitor CAA publication updates and revise course content and scheme documentation when regulatory guidance changes. Aerodrome operators using AACS AVDP schemes can be confident that their scheme meets the regulatory standard at all times — not only at the point of initial design.

Bespoke for Every Client

AACS designs AVDP courses and schemes for aerodromes of all sizes and types — from major commercial airports with complex multi-runway layouts and high vehicle traffic density through to smaller licensed aerodromes where ground handling is conducted by a handful of permit holders. The training content, the assessment standard and the scheme complexity are all calibrated to the specific operational environment — ensuring that the scheme is proportionate, usable and effective rather than over-engineered for a simple environment or inadequate for a complex one.

Our Advisory Philosophy for Airside Vehicle Driver Training

AACS approaches AVDP training with a conviction that is consistent with everything we do in aviation safety: a permit issued to a driver who does not genuinely understand the airside environment is not a safety control. It is a document. The purpose of the AVDP course is to produce drivers who are genuinely competent to operate in the airside environment — not drivers who have attended a course and answered enough questions correctly to receive a card.

✔  Every course is calibrated to the specific aerodrome — its layout, its procedures, its hazards and its local rules

✔  Training covers all CAP 642 content areas in full — not a shortened version that skips the difficult or operationally complex elements

✔  Assessment is rigorous — both theoretical and practical, with a pass standard that reflects genuine safety competence

✔  Human Factors content is integrated throughout — situational awareness, complacency, distraction and safety reporting are not an afterthought

✔  Scheme design gives aerodrome operators a complete, CAP 168-compliant framework — not just a training course

✔  Renewal training is substantive — updated with current safety data and aerodrome changes, not a repeat of initial content

✔  Our advice is independent — we have no commercial relationship with any aerodrome operator, handling company or permit management software provider

We deliver AVDP training and scheme design that is operationally grounded, regulatory compliant and built on direct experience of the airside safety environment. Whether you are designing an AVDP scheme for a new aerodrome, revising an existing scheme to meet current CAP 168 requirements, or delivering AVDP training to a new cohort of permit applicants, AACS provides the expertise to produce training and schemes that genuinely protect the airside environment.
