DIFFERENCES TRAINING FOR VARIANTS WITHIN THE SEP AEROPLANE CLASS WITH AN ELECTRIC ENGINE SYSTEM
As regards electric engines, the differences training should, on the basis of the AFM of the relevant aircraft, include at least all of the following:
(Note: The following list solely addresses the training needs with regard toelectric engines and must not be understood as an exhaustive differences training syllabus.)
(a) Theoretical knowledge
(1) Aircraft general knowledge:
(i) electric engine;
(ii) high-voltage batteries, including their storage;
(iii) electric engine and battery indication and monitoring instruments;
(iv) electric engine and battery limitations;
(v) electric battery endurance;
(vi) electric battery life and effects of battery age on performance.
(2) Operational procedures:
(i) electric engine and battery pre-flight inspection;
(ii) charging of the battery;
(iii) charging errors;
(iv) long-term battery storage procedures and limitations;
(v) in-flight engine/energy monitoring and management;
(vi) go-around with minimum energy;
(vii) emergency procedures:
(A) engine/battery fire on the ground and in the air;
(B) engine/battery overheat;
(C) partial and complete loss of engine power (CLOP);
(D) loss of cooling function;
(E) failure/loss of engine/battery instruments;
(F) in-flight engine restart procedure.
(3) Flight planning:
(i) energy consumption for all phases of the flight;
(ii) mission and contingency planning;
(iii) minimum reserve energy planning.
(b) Flight instruction
The dual flight instruction should include the practical exercise or, in the case of emergency procedures, a simulation of all the elements listed in point (a).
AMC1 FCL.710(a) details differences training for SEP aeroplanes with electric engines, covering theoretical knowledge, operational procedures, emergency handling, and flight instruction based on the AFM.
