Engine Failure during the Cruise Flashcards
First steps
What’s the first thing to do once there is an engine failure?
Fly the aircraft: there will be
- Lack of power from one of the engines
- Yawing effect
- Roll towards the dead engine
How do we counteract these adverse effects?
- Center the ball
- Apply 5º bank toward the operative engine
- Pay attention to vertical and horizontal navigation
- Maintain heading
- Angle of minimum drag, which improves our climb performances
What do you do once you have taken control of your aircraft?
- Look for blue line
- Only in case of flying over Vmc (66 KIAS) we will be able to apply full power if it isn’t applied yet
- TAKE OFF POWER (MAX 5 MIN) until we can identify which of the engines has failed, advancing the mixtures, propeller controls and adjust for 38’’ of MAP
- CHECK BOTH FUEL SELECTORS: Both in the ON position
- CHECK MAGNETOS: Both in ON position
- CHECK MIXTURE CONTROLS: Both in the RICH position
- IDENTIFY THE INOPERATIVE ENGINE: You must be 100% sure which engine has failed, check RPM’s, MAP and FF) also check direction of yaw (Dead foot, dead engine)
- CHECK THE ENGINE PARAMETERS: once safe altitude is reached, check all the parameters to determine what the cause of the engine failure could have been, visually check the engine in order to decide on the next steps:
- *Restart: RPM above 1000 revolutions
- Secure the dead engine: RPM below 1000 revolutions
If the temperatures (oil and cylinder head) are too high or too low?
Adjust the cowl flaps accordingly
- CHECK THE FUEL QUANTITY as engine failure may have been cause by a lack of fuel
Once all these steps have been performed, what decision do you need to make?
RESTART or FEATHER AND SECURE THE DEAD ENGINE
What do you need to be careful about regarding the feathering lock?
You must be sure to move the propeller control into the “FEATHER” position before engine speeds falls below 800 RPM
What is the procedure of RESTART?
If the dead engine speed hasn’t fallen below 1000 RPM, we will attemp a restart, in the case it has fallen below 1000 RPM, we proceed directly to save the engine following the feather procedure
*D/E Alternate air: ON
*D/E Fuel Selector: XFEED
*D/E Magnetos: ON
*D/E Auxiliary Fuel Pump: HI
What’s the FEATHER procedure?
FEATHER AND SECURE THE DEAD ENGINE
If restart has failed, secure the engine as soon as possible, so as to create minimum drag.
*IDENTIFY DEAD ENGINE: DEAD FOOT, DEAD ENGINE
*VERIFY: Close throttle of dead engine
*FEATHER: First we move mixture level to the idle cut off position, then the propeller lever to the feather position
*D/E ALTERNATE AIR: OFF
*D/E COWL FLAP: CLOSED
*D/E FUEL SELECTOR: OFF to avoid unbalance, setting fuel selector of the operating engine in XFEED position will be recommended every each 15min and then ON again
*D/E MAGNETOS: OFF
*D/E ALTERNATOR: OFF check ammeter load (max 60amp) and reduce the use of electrical equipment (if applicable)
What do you do once the above procedures have been performed?
DECLARE EMERGENCY
Call emergency frequency 121.5
If under ATC already, call frequency in use
Declaring the emergency:
MAYDAY x3
Callsign
Position
Nature of emergency
Souls on board
Squawk 7700
Proceed to the nearest possible airport
What do you need to note about selecting the fuel pumps to HI if you do not need it?
Engine could choke, and possibility of an engine stop
What do you need to note about a lack of indication on the fuel flow with the fuel pump in HI?
may be a loss in the system or a lack of fuel in the tank
What MUSN’T YOU DO regarding the fuel pumps?
DO NOT use auxiliary fuel pumps unless it is necessary to clear the fuel vapors (LO position), or in case of engine driven fuel pump failure (HI position)
What must you note when using fuel from one tank?
Autonomy will be considerably reduced
