Safety, Compliance & Operational Advisory for Commercial Airlines,
Regional Carriers and Charter Operators

Aerospace and Aviation Consulting Services (AACS) provides
comprehensive safety, regulatory, and operational advisory to commercial airlines, regional carriers, charter operators, and business aviation organisations worldwide.

Our capability spans start-up certification through to established airline operations, covering the full regulatory lifecycle from initial AOC application to ongoing compliance monitoring, safety system maturity, and operational performance improvement. We bring genuine airline experience to every engagement — our team includes former airline training captains, regulatory inspectors, safety managers, and accident investigators.

AACS aligns all advisory with ICAO Annex standards, EASA regulations (EU 965/2012 and associated implementing rules), UK CAA frameworks, and the national regulatory requirements of client jurisdictions, ensuring compliance that is internationally consistent and operationally credible.

multiple regulatory jurisdictions and fleet types.

standards and build genuine competency.

Integrated Airline & Charter Advisory Philosophy

AACS approaches airline and charter operator advisory with a
single governing principle: safety, compliance, and operational performance are
not trade-offs — they are mutually reinforcing when properly managed.

  Regulatory compliance must be built into operations from the ground up, not retrofitted after approval

  Safety Management Systems must generate actionable intelligence, not administrative burden

  Operations Manuals must be written for the crew and the inspector — not for the shelf

  Aircraft acquisition decisions must be operationally and financially independent of sales influence

  Investigation findings must be objective, evidence-based, and capable of withstanding legal scrutiny

  Training programmes must build genuine competency, not simply satisfy currency requirements

We deliver advisory that is independently verified, operationally credible, and built on over 30 years of real-world airline and charter aviation expertise.
