Engine Failure During take-off Flashcards
What do you do should an engine fail during the take-off roll before becoming airborne?
Close both throttles immediately
Bring acft to a stop
What if you become airborne and you have an engine failure before having reached the single-engine best rate of climb (Vyse)?
Same procedure as before.
Why would an immediate landing in this case is usually inevitable?
Because of the altitude loss fruit of the efforts to increase the speed to Vyse
What must the pilot have determined before take-off?
At what altitude, airspeed and acft config must exist to permit the flight to continue in event of an engine failure
What should the pilot be ready to accept?
The fact that if engine failure occurs before these required factors are established, both throttles must be closed, and the situation treated the same as engine failure on a single-engine airplane
What may the pilot decide if it has been predetermined that the engine-out rate of climb under existing circumstances will be at least 50 fpm at 1000 ft AGL, and that at least the engine-out best angle of climb speed (Vy) has been attained?
He/she may decide to continue the take-off
What if airspeed is below Vxse and the gear has not been retracted?
Take off should be abandoned immediately
What if Vxse has been obtained and the gear is in the retract cycle?
Pilot should climb with Vxse to clear any obstructions, and thereafter stabilize the airspeed at Vyse while retracting gear and flaps and resetting all appropriate systems
What should the pilot do once the decision to continue flight is made?
Attain and maintain Vyse
Even if altitude cannot be maintained, it is best to continue to hold that speed because if would result in the slowest rate of descent and provide the most time for excuting the emergency landing.
After the decision is made to continue flight and a positive rate of climb is attained, the landing gear should be retracted as soon as practical
What if the acft is just barely able to maintain altitude and airspeed?
A turn requiring a bank greater than approximately 15º should not be attempted
What could happen if you make a turn under these conditions?
Both lift and airspeed will decrease
Consequently, it is advisable to continue straight ahead whenever possible, until reaching a safe maneuvering altitude
At that time a steeper bank may be made safely - and in either direction.
There is nothing wrong with a banking toward a dead engine if a safe speed and zero sideslip are maintained
What should the pilot do if the engine fails after becoming airborne?
Hold heading with rudder and simultaneously roll into a bank of about 5º toward the operating engine.
In this altitude the airplane will tend to turn toward the operating engine, but at the same time, the asymmetrical power resulting from the engine failure will tend to turn the airplane toward the dead engine.
This result is a partial balance of those tendencies and provides for an increase in air- plane performance as well as easier directional control
What is the best way to identify the inoperative engine?
Note the direction of yaw and the rudder pressure required to maintain heading
To counteract the asymmetrical thrust, extra rudder pressure will have to be exerted on the operating side.
To aid in identifying the failed engine, some pilots use the expression: “dead foot - dead engine”.
Never rely on tachometer or manifold pressure readings to determine which engine has failed.
After power has been lost on an engine, the tachometer will often indicate the correct RPM and the manifold pressure gauge will indicate the approximate atmospheric pressure or above
What do you do if the engine failure occurs on ground?
Take-off must be aborted. SP’s actions have to be carried out according to the take-off and emergency briefing
- PF calls: “STOP”
- Brakes
- Throttles close
It is to be considered that all three actions need to be carried out at the same time when the engine failure is noticed.
