I think it is for training skippers only!!!! along way to go for me then…

Skycruiser – do they get you doing that in the sim or could you end up doing it for the first time for real?

cheers for that Skycruiser!:)

Here is how to set the power…..

This technique is suitable for ferry take-off from wet or dry runways.

Align aircraft with runway centre line, release park brakes and hold aircraft on foot brakes.
F/O holds control column forward until Capt takes control.
Apply take-off thrust on the symmetrical engines and commence take-off with EPR set.
As the aircraft accelerates, the Capt simultaneously advances the asymmetric engine and maintain directional control using rudder pedals.
Excessive asymmetric thrust at too low a speed causes the nose wheel to skip under side load.
F/O called speeds in 10 KT increments from 50 KTS.
(At about VMCG the Capt removes hand from nose wheel steering tiller to control wheel and calls ‘I have control’)
Steadily increase thrust on asymmetric engine to attain full take-off thrust at a speed near to, but not below ground minimum control speed.

NOTE: Thrust, should gradually be set on the asymmetric engine once the airspeed indicator has started to move. Hasty power application below 30 KTS can lead to directional control problems.

And that’s it….

I know that in the UK you can ferry one engine with passengers on board. It may be possible to ferry 2 (presumably without passengers) but I don’t know for sure. Skycruiser is the one to answer this.

With regard to the three engine ferry scenario, I should think they would use a slightly higher thrust setting on the missing side than the two engined side and also use some rudder trim. I shall have to ask Skycruiser again or my 146 mate.

Also Wys can you tell how to they maintain the engine thrust equal on both wings when an aircaft like in the pic is missing an engine? And if they put that one engine on full thrust and the other two on lower thrust to match it equal, cant it cause problems in-flight?

Cheers for that Wys…but still it will be possible for a 747 to ferry two engines?

The missing engine scenario would only be permitted for ferrying the aircraft empty to somewhere where it can be repaired. It is referred to as a ‘three engined ferry’.
I worked for Virgin on the first flight they did when carrying an extra engine with passengers on board. I have a picture similar to the one above which I took on the flight. I’ve been meaning to dig it out for ages. Only 1 engine is permitted to be carried at a time.

i think it should be…….. havent seen 2 engines being ferryd before thou.

Could it be possible to ferry 2?

It’s quite normal for a 747 to ferry a spare engine on it’s wing. When I mentioned the anniversary of the Air India bombing recently the plane in question was ferrying an engine back from Canada to be repaired at it’s engineering base.

As for the missing engine, did it fall off ?

I know it would be Ok, with probably no problems, but flying on a Jumbo with Just the 3 engines would gimme a fright. Especially if I were sitting just in front of the wing, and everytime you look out of the window, you see theres only one engine on the wing.

Nice pics. 🙂

Yes it’s just a ferry for an aircraft in singapore

Steve , do you know the story of this 5th engine?Is she just ferrying this engine?
