From 13 October 2025 new versions of the ATPL (Aeroplane) examination information book, ATPL (Helicopter) examination information book and the S76 Performance and Operations Handbook will become effective.
The changes bring the wording of these documents into line with the current regulations, e.g. using Equi-time point (ETP) instead of Critical point (CP), various fuel abbreviations to include contingency fuel and final reserve instead of fixed reserve.
