A320 Engine Failure After V1

[Boyington]

The FCTM states that the flight crew must delay the acceleration for securing the engine. What exactly is the reason for it? Is it just to manage the tasks on priority?

[vilas]

Securing Failed/Damaged engine is first priority to prevent further complications from it. Acceleration to clean up and resuming climb is to maintain certain gradient profile for terrain clearance. There are two limiting altitudes for acceleration, the minimum and maximum. By exceeding the minimum acceleration altitude the gradient of climb profile is not affected. But the maximum should not be exceeded as it will cause 10mts limit on takeoff thrust to be exceeded.

Does the 10 min limit apply to a flex take off? Or is it only TOGA?

[Capt Scribble]

Depends whether the Flex gives you thrust below or above MCT.

[763 jock]

Unlikely it would ever really be noticed in reality. More important priorities to deal with. I remember on my previous type (setting MCT manually) would often be an increase in thrust after a high assumed temp take off. Hence my question. Is there any way of knowing when the take off flex is equal to or exceeds MCT?

[Goldenrivett]

Does the 10 min limit apply to a flex take off? Or is it only TOGA?

It applies to both.
You have only one procedure common to every take off you do - flex or TOGA and everything in between.
KISS.

[vilas]

Procedurely the limit is on takeoff thrust whatever was used.

I’ve found out during a couple of sim sessions that if you don’t delay acceleration until securing the engine, you might find yourself (depending on how fast the ECAM is being performed) at green dot speed and in time to resume climb with the engine still not secured, which trust me, becomes quite an interesting workload to handle

[ANCIENT]

Airbus put a lot of thought into the recommended procedures and they work. Why try to reinvent the wheel?

[FlightDetent]

Yep. This procedure was only introduced about 8-10 years ago.
