Hello,

I just need some advise on RTO policy on 767.
Do you Reject takeoff if you encounter an engine fire (w/o thrust loss) near the speed of V1? How about on a slippery runway?

I think, with the thrust reverser, it will not be that bad idea to reject even at high speed near V1, even on slippery runways.

Boeing said that on B767, with both engine running, the required feild length to stop (in case of Engine failure at V1) was longer by 500m than the length required to stop with only one engine running.

I think, the point will be whether we can believe in the thrust reverser in case of engine fire or not.

I appreciate your kind advise. Many thanks in advance!

I would imagine the 767 is no different to any other large multi engine aircraft:

<V1 stop on the runway, then the memory items

>V1 continue the take off.

When above 80kts, you tend to only stop for major problems, engine fire / failure, etc.

If i remember correctly, RTOs are calculated with both / one engines at Idle / wheel brakes only if its a dry runway, or brakes / reverse thrust on one engine with a wet runway

Overrun is the highest incident cause on high speed RTO.

Close to V1 > GO minded.
Lift off, manage the failure and return or divert single engine.


On slippery rwy > much more GO minded. RTO close to V1 is a huge risk decision.

You need to read more and imagine less. Henry has given you the clue above.
