Aerodynamic & Operational Physics
- Carburettor throttle arms are spring-loaded to OPEN (high power) or IDLE depending on design.
- If stuck at HIGH POWER: Use mixture control to modulate power, fly to long runway, cut mixture on short final.
- If stuck at IDLE: Execute forced landing gliding approach to suitable field.
CASA & FAA Exam Gotcha Alert
Exam Trap: If throttle fails wide open, do NOT immediately shut down engine at altitude. Use mixture leaning to maintain level flight to an airfield.
Frequently Asked Questions & Exam Explanations
How can you control engine power if the throttle cable snaps in the open position?
Use the mixture control to carefully lean or rich the engine to adjust thrust and altitude.
