i used the 767 takeoff_EX97 Rob V2.31beta to calculate the fuel i needed for a flight from EHAM to EGLL.With a fuel load of around 61,132lbs, i got the followign flap target speeds:1: 1735: 15910: 15620: 14425: 13930: 136are these correct?so basically this will mean when I'm flying at a speed of 180KIAS i should be at flaps 0?thanks in advance

EHAM to EGLL is less than an hour flight. You don't need anywhere near 61,000lbs of fuel. As a quick estimate, I usually assume about 10,000lbs per hour of flight plus an extra 10,000lbs for taxiing, holds, diversion, etc. I usually land with about 10,000lbs onboard.Lee Hetherington (KBOS)

Using 767 PIC, as in the real aircraft, the automatially set takeoff airspeed bug settings represent the following retraction schedule with a flaps 15 takeoff configuration at MTOW:First bug = V1 Decision SpeedOrange Bug = V2 best engine-out rate of climb safety speedSecond bug = Not usedThird Bug = Flaps 5Fourth Bug = Flaps 1Fifth Bug = Flaps 0 (clean)This is the basic Boeing 767 Aircraft specified retraction schedule that assures a guaranteed overbank stall protection to I think 45 degrees of bank at MTOW before onset of the stick shaker. In real world ops, especially at or near MTOW, this basic schedule is not used because the aircraft would exceed maximum allowable flaps down airspeeds (VFe's) if using these 'standard' flap retraction speeds. Therefore, practically all carriers interpolate this basic schedule and retract flaps at -20 kts IAS lower than this standard and forego the generous overbank protection afforded (it's not really needed in real world ops anyway).So the actual retraction schedule you'd use if you were a real 767 pilot would be:First bug = V1 Decision SpeedOrange Bug = V2 best engine-out rate of climb safety speedSecond bug = flaps 5 Third Bug = flaps 1Fourth bug = flaps 0 (clean up speed)Fifth bug = not used A flaps 5 takeoff configuration would use the logical variation of the above retraction schedule:First Bug = V1Orange = V2Second = Flaps 1Third = Flaps 0Fourth = not usedFifth = not used

61k lbs of fuel ??Assuming no holds 12000lbs of fuel will easily suffice from Schip - Heath.

A319,Others have commented on the total fuel required (yep, way too much) but I will comment on your speeds. They do not look at all right to me. Assuming ZFW of about 245,000 lbs (default value) and a fuel load as such you should be around 300,000 lbs. I don't have PIC running right now but from experience I would suggest those speeds are all too low (except maybe the Vref Flap 30) .Vref (flap 30) is probably close to 136, maybe a bit higher,around 140. Therefore your clean speed should be Vref + 80 or around 216 knots (not 180). Flap 1 speed would be Vref + 60 and Flap 5 Vref + 40. There is no Flap 10 in PIC767 that I can remember. The settings are 0,1,5,15,20,25,30.In any event, the hidden click spot on the ASI will set the bugs for you based on the current aircraft weight. Also, the FMS under INDEX / APPROACH will give you Flap 20, 25 and 30 speeds based on the weight shown in the upper left corner (you can enter a different weight if you like).Kevin in CYOW

Also you can actually retract the flaps at the 3rd bug when using flaps 5 without being close to stall?? Thank You.
