February 4, 20179 yr The three-engine ferry procedures are an extra (cost!) addition to the FCOM so it may be that PMDG have not included them. Phillippe may come up with some more stuff but the main points: - Flap 10 - Transponder in TA only - TO2 - Do not select ENG OUT prompts - Place the GPWS GEAR OVERRIDE to OVERRIDE - No autothrottle for takeoff Then pretty much as you did -- set the two symmetrical engines to takeoff thrust and (above 50 kts) slowly increase thrust on the third engine to reach takeoff thrust no earlier than Vmcg. The takeoff run is quite a handful on your own -- my manuals have the FO handling the control column (holding forward/aileron input for crosswind etc) to leave the Captain's hands free to faff with the thrust levers (and keep it straight with the tiller/rudder) before the Captain takes all the controls back once takeoff thrust is set. Once airborne, it's a normal 3-engine climbout. Select CON thrust and packs on (CON AIR) once the flaps are up, arm the autothrottle and select and ENG OUT on the CDU. You can also then put the GPWS Gear override back to normal. Simon Kelsey

You are right about the takeoff run, I will admit I was all over the runway until the rudder kicked in. Wes Meyer
February 4, 20179 yr Simon sums up it very well. here is the technique given in the AFM: T A K E O F F D I S T A N C EThe scheduled one-engine-inoperative ferry takeoff distance is 1.15times the measured horizontal distance from brake release to the35-foot height point when the one-engine-inoperative ferry takeoffprocedure given in this section is followed.T A K E O F F T E C H N I Q U ENOTE: This technique is suitable for ferry takeoff from wet or dryrunways.ONE OUTBOARD ENGINE INOPERATIVE1. Pilot Flying (PF) aligns airplane with runway centerline andsets brakes.2. PF sets approximately 1.06 EPR on all operating engines.3. Pilot Not Flying (PNF) holds the control column forward ofneutral.4. PF releases brakes and applies takeoff thrust on the inboardengines.5. PF steers with tiller and applies full rudder toward theoperating outboard engine.6. As the airplane accelerates, the PF slowly advances thrust on theoperating outboard engine and maintains directional control usingvery small tiller angles. Rudder pedal nosewheel steering isoverridden with the tiller.7. The PF steadily increases thrust on the operating outboard engineto maintain directional control with minimum nose wheel scrubbingand attains full takeoff thrust at a speed near but not below theone-engine out ground minimum control speed (VMCG). The ruddershould be used to assist directional control and should be nearmaximum deflection to get predicted takeoff performance.8. PNF monitors the thrust application on the operating outboardengine, calls airspeed in approximately 20-knot increments andadvises the PF when takeoff thrust is being approached, andmaintains wings level with small wheel changes.9. After the operable outboard engine attains takeoff thrust, the PFassumes control of the control column and wheel and completes thetakeoff and climbout using normal procedures as described inSection 4 of the basic Airplane Flight Manual.SECTION 4.1 – GENERAL (Continued)T A K E O F F T E C H N I Q U E (Continued)NOTE: 1. RTO autobrakes are not available when any thrust lever isnot advanced.2. Do not follow any noise abatement procedure that restrictsairspeed.3. Retract gear and flaps as soon as feasible.ONE INBOARD ENGINE INOPERATIVEUse the same procedure as for takeoff with an outboard engineinoperative except that takeoff thrust is initially applied on theoutboard engines. Increase thrust on the operating inboard engineso that takeoff thrust is obtained at 80 to 90 knots.enjoy.Phil and i think that as Simon said it was PF as the captain and PNF the FO. but some operators and regulators may have done it differently.
