aircraft systemsFAA-published sample question (ATM, Aug 2021)
What could cause a turbine engine hot start?
A
Lack of airflow due to insufficient turbine rpm.✓ Correct Answer
B
Inlet and compressor airflow imbalance.
C
Insufficient fuel in the combustion chamber.
Explanation
A hot start occurs when the engine lights but exhaust temperature exceeds limits, typically because there is too little airflow through the engine (insufficient rpm from the starter) or too much fuel. Too little fuel would cause a failed or slow start, and a compressor airflow imbalance is associated with stalls.
