What the paper testsA piston twin that runs on jet fuel
The AE300 is a turbocharged, geared, liquid-cooled compression-ignition engine burning Jet A-1, controlled through an electronic control unit with a single power lever per side.
Almost every habit from a carburetted Lycoming is wrong here, and the paper knows it. Mixture, carburettor icing and magneto questions do not apply; ECU logic, gearbox life and coolant do.
What is insideOne variant, nothing else
The Austro and Thielert DA42s are separate subjects on AIVR CPL with separate banks and separate papers, because they are different engines with different limitations, different power settings and different failure behaviour.
A practice set here is drawn only from the Austro bank.
Where marks go missingEngine-out numbers
The multi-engine speeds — VMCA, VSSE, VYSE — and the single-engine performance figures are where this paper concentrates its marks, together with the ECU and electrical questions candidates skip because they feel like avionics.
The electrical system deserves particular attention: on a compression-ignition twin, losing electrical power is an engine problem, not just an instrument one.
How to work through itA small bank, so run it dry
Compact enough to work end to end rather than sample. Practice mode through the systems, then test mode until nothing new appears, then the 50-question paper on the clock.
