The ATPL is the highest pilot licence and is required to command multi-crew commercial air transport aircraft. In EASA training, students often complete ATPL theory early and fly on a CPL with a 'frozen ATPL' until they meet the 1,500-hour experience requirement.
The Airline Transport Pilot Licence is the highest pilot qualification, required to act as pilot in command in multi-crew commercial air transport. Issue requires 1,500 hours with specific experience components — which is why the industry runs on the 'frozen ATPL': a CPL holder with completed ATPL theory and a multi-engine instrument rating who flies as first officer until the experience requirements 'unfreeze' the full licence.
EASA ATPL theory spans 13 subjects with structured sitting and attempt limits inside a defined window, and the passes carry validity clocks toward licence issue. The FAA equivalent (ATP certificate) runs its own 1,500-hour framework with the ATP-CTP course as a prerequisite.
Why it matters for flight schools
For ATOs, the ATPL is programme architecture: theory scheduling, exam windows and rating sequencing decide whether a cadet finishes in 18 months or 26. The validity clocks are the silent killers — a stalled student can age out of exam windows, converting a delay into a repeat of thirteen exams.
How FlightLogger handles it
FlightLogger tracks every ATPL-track student's exam attempts, windows and validity dates alongside flight progress — so the Head of Training sees clock risks months before they detonate.
Frequently asked questions
What is a frozen ATPL?
Industry shorthand for CPL + completed ATPL theory + multi-engine instrument rating — the package airlines hire first officers on. The ATPL 'unfreezes' into a full licence once the pilot accumulates 1,500 hours with the required experience mix.
How long is ATPL theory valid?
The exams must be completed within defined sitting windows, and passes remain valid for licence and rating issue for limited periods thereafter. The practical consequence: keep flight training moving after theory, because the clocks do not pause.
