Aircraft General Knowledge
EASA ATPL Subject 021
EASA ATPL subject 021 — Aircraft General Knowledge covers airframe structures, hydraulic and pneumatic systems, landing gear, flight controls, powerplant systems (piston and turbine), electrical systems, fire protection, fuel systems, ice and rain protection, and cabin pressurisation. The subject requires understanding both principles and specific system parameters.
ATPLCards includes 186 AGK flashcards focused on the key facts, limits, and system details that exams test — from turbine temperature limits to hydraulic system pressures and electrical bus configurations.
Sample Flashcards
Q: Diffuser function in turbine engine is to?
A: Drop air velocity, increases the static pressure for optimal fuel burning
Q: What is fail-safe design?
A: A structure designed so that if one part fails, adjacent parts provide an alternative load path for a limited time
Q: What is Integrated Drive Generator (IDG)?
A: Combination of an alternator/generator and a Constant Speed Drive (CSD) unit. Has its own oil system
Q: Specific gravity for Jet A1 at 15 degrees is?
A: 0.77–0.84
