Updated: Dec 17, 2020
Engine Failure During Takeoff Roll Lesson by wifiCFI
Objective
To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with an engine failure during takeoff before Vmc.
Knowledge
The applicant demonstrates understanding of:
Factors affecting VMC.
Vmc (red line) and Vyse (blue line).
Accelerate/stop distance.
Risk Management
The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing:
Failure to plan for engine failure during takeoff.
Improper aircraft configuration.
Distractions, loss of situational awareness, and/or improper task management.
Engine Failure Takeoff Roll (AFH C12)
A takeoff can be rejected for the same reasons a takeoff in a single-engine airplane would be rejected.
Once the decision to reject a takeoff is made, the pilot should promptly close both throttles and maintain directional control with the rudder, nosewheel steering, and brakes.
Aggressive use of rudder, nosewheel steering, and brakes may be required to keep the airplane on the runway.
Particularly, if an engine failure is not immediately recognized and accompanied by prompt closure of both throttles.
However, the primary objective is not necessarily to stop the airplane in the shortest distance, but to maintain control of the airplane as it decelerates.
In some situations, it may be preferable to continue into the overrun area under control, rather than risk directional control loss, landing gear collapse, or tire/brake failure in an attempt to stop the airplane in the shortest possible distance.
Accelerate/Stop Distance
Accelerate-stop distance is the runway required to accelerate to either Vr or Vlof (as specified by the manufacturer) and, assuming an engine failure at that instant, to bring the airplane to a complete stop.
See “Multi-Engine Performance Charts” for an example on how to run the chart.

The Maneuver
Check final approach for landing aircraft
Line up on runway centerline
Advance throttle to full for takeoff
Accelerate down the runway
At engine failure:
Close both throttles immediately
Use brakes to maintain aircraft control and come to a stop
Common Errors
Failure to adequately clear the area
Improper aircraft configuration
Failure to promptly recognize engine failure
Failure to close both throttles immediately
Failure to maintain directional control
ACS Standards
Close the throttles smoothly and promptly when simulated engine failure occurs.
Maintain directional control and apply brakes.
