automatc asymmetric correction
 

In the event of an engine out at take off , would a modern jet provide automatc asymmetric correction or is manual input still required? In whatever interval betwen correction, would passengers be particularly aware of the rolling etc?

Many thanks

KLOS,

Varies with the acft type. 777, 787 corrects it for you, 737s do not. Airbuses help you a lot, but do not know details.

Many thanks, Sir

Search the web for "Rudder Boost"

Or: "Thrust Asymmetry Compensation", a.k.a. "TAC"

TAC : Thrust Asymmetry Compensation

Works well (if the 777 sim is to be believed), slight delay in it taking effect, and doesn't completely take out the asymmetry, as I understand it all in the interests in ensuring the pilot is left with some physical/tactile clues as to the failure. Also worth bearing in mind that it doesn't "detect" all failure modes, so you still have to ready and able to apply rudder the old fashioned way if things go wrong.

On a calm day the more aware passenger might just detect any yaw induced by engine failure, but there shouldn't, ideally, be any significant rolling effect. On a properly handled takeoff an "benign", non-noisy :eek: engine failure would be almost impossible to detect from the passenger cabin.

Correct during a take off, during a go around from a dual channel approach the autopilot rudder control takes care of asymmetry until another roll mode is selected.

Captain Wiggy,

Many thanks for this most helpful increment to my lay understanding of flying. I note you fly my favourite bird ( 777) - wonder how you feel about flying the 'composite ' derivative newcomer.

Captain Dent,

Many thanks for the B737 perspective.

Grateful to you both for taking the time-

:ok:

I'm sure it'll fly just fine as long as the glue has set....:\

:ooh:

............ and I really enjoyed the TCA article and amazingly was able to follow the logic- fascinating the bit about manual rudder over input - these boffins are just amazing
