737 Engine Failure After V1

What if an engine fails after takeoff?

Although it is very unlikely to have an engine failure, pilots are trained to recognize engine failure and how to handle the situation. Below is a situation where an engine failure is encountered during the takeoff roll.

Above is the profile for a normal Take-off and an engine failure after take off. I ripped from the Boeing 737 book. Since tomorrow I’m I have a simulator session on engine failure after takeoff, I’m going to write about engine failure after takeoff aka EFATO.

Prior to takeoff, the takeoff thrust is set. Its normally around 40% initially. Then hit the TOGA button to make it accelerate to 90.2%-96.1%. If there’s any malfunction before 80kts the captain will reject the Take off. After 80kts and before V1 the captain will only reject for serious problems like engine failure or engine fire. After V1 the takeoff must continue no matter what happens. This is to prevent the Aircraft from overshooting the runway trying to stop the plane.

V1, VR and V2 is calculated before every flight. It depends on the runway length, aircraft weight, outside air temperature, and everything else. So if there’s any malfunction after V1 the takeoff will continue. Nothing will be done until 600’. Even if there is engine fire, no action will be taken until 600’. Take note that with a single engine the climb will be slightly slower.

At 400’ normally the captain will choose mode HDG SEL.

And at 600’ both pilots will determine the problem and if there’s any recall checklist to be done, now is the time to do it. If it’s an engine failure, do nothing, yet.

At 800’ set flaps up speed around 210-220kts and retract flaps 5 to flaps 1 then flaps up. After the flaps are up LVL CHG is selected and MAX CONT thrust is set bank angle 25degree.

After all that the Non Normal Checklist (NNC) begins. Thrust leaver is closed, engine start leaver to cutoff, etc etc. After the Engine Failure NNC, the after takeoff checklist is accomplished.

The captain will inform the cabin while the co-pilot calls the control tower. The pilots will decide whether to continue or to come back and land. Normally, one engine is sufficient to bring the plane safely to the original destination.

So that’s about the exercise on the next session. The others is ILS and some and Non-precision approaches with single engine inoperative in WMSA, Subang Airport.
