Emergencies Flashcards
Engine failure during take-off run!
Throttle - fully closed Brakes - apply Flaps - retract Mixture - idle cut-off Ignition - off Master switch - off
Engine failure after take-off!
Airspeed - 73kts
Landing area - select
Radio - Mayday
Fuel - mixture idle cut off, fuel selector off
Ignition - off
Switches - master off
Harness - tight and door cracked open
Engine failure during flight!
How do you restart?
Airspeed - 73kts Carb heat - on Primer - in and locked Fuel pump - on Fuel selector - change tanks Mixture - rich Magnetos - both (or start if prop has stopped) *if fuel starvation, takes 10s to restart after change tanks
Forced landing!
a) Initial actions?
b) On restart failure
c) Once committed
a) carb hot, 73kts, assess surface wind, select landing area, plan approach
b) mayday, transponder 7700, brief PAX
c) mixture idle cut off, fuel pump off, fuel selector off, mags off, master switch off, harness secure, doors unlatched,
Electrical fire in flight!
Master switch - off Cabin vents - open Cabin heat - off Switches - off Fire extinguisher if needed ATC - advise of situation Land - as soon as practicable
Electrical failure!
Ammeter - put all lights on, if no increase in reading assume alternator failure
Electrical load - reduce
Circuit breakers - reset once if popped
Ammeter - check again - if normal monitor and inform engineering; if zero turn off alternator switch, minimise load, land soon as practicable, advise engineering.
What is the battery duration in the case of alternator failure?
36 minutes
Electrical Overload!
Ammeter is indicating 20amps above known electrical load.
Monitor ammeter for 5mins.
If persistent overload land as soon as practicable and advise engineering.
Inadvertent icing encounter!
Pitot heat - on
Outside air temperature - turn/climb/descend for warmer air if possible
Cabin heat - fully on
Throttle - higher RPM (minimise ice build up on prop)
Land as soon as practicable
Flaps - keep up
Approach speed - higher due higher stall speed
Landing - power on landing
Carburettor icing!
Symptoms?
Actions?
Unexpected loss of rpm and engine rough running.
Carburettor heat on (if using continuously lean mixture for max RPM)
Why wouldn’t you use flaps when you have ice accumulation?
With ice accumulation on horizontal stabiliser, a change in wing wake airflow could reduce elevator effectiveness.
Engine fire during start up!
a) will start
b) won’t start
Continue cranking for engine start. a) 1700 rpm for 2-3mins Shut down checklist engineering to expect b) Throttle open Mixture idle cut off Radio ATC Master switch off Magnetos off Fuel selector off Fuel pump off Fire extinguisher- evacuate and use if required Engineers to inspect
Engine fire during flight!
Mixture idle cut off Throttle closed Fuel off Fuel pump off Radio Mayday Squawk 7700 Master switch off Cabin heat/air off Airspeed 90kts (or faster to extinguish, 73kts to do forced landing) Slip to keep flames away from fuel tanks
