Hi Guys!I set the flap speeds using the "F" that appears on the ADI. It doesnt appear for flap settings 25/30 (having set v ref in the Fmc?Any ideas any one?Is it possible to arm and get autospoilers on landing?RegardsSimmslot

hi,first one:i have no clue whatsoever.second one:if you use the shift+/ command they should be armed,and upon touchdown they should go up,might also be upon engaging reverse thrust,i'm not sure.

Hi!On the real aircraft, it works as this:If you arm the speedbrakes (pull the lever out of its detent and move it downwards a bit) it will automatically extend upon touchdown with both thrust levers at or near idle. The speedbrakes will also extend whenever reverse thrust is selected. For this, the speedbrake lever does not have to be in the arm position. Ideal for aborted takeoffs.Regards,Mark

Well regarding your Fs, you probably thought the Fs were for the following sequence:Flaps 1 - 5 - 15 - 20 - 25 - 30. They're not! This is the flap sequence:Flaps 1 - 5 - 20 - 30.You don't normally use the intermediate flap settings and the Fs don't take them into account either.

That suddently makes sense!Flap 1, Flap 5, 15 is a takeoff intermediate setting, Flap 20 and approach flap (be it 25 or 30).

Well,Iz simplifies it a bit :). And yes, I know Iskander is a real 757 pilot :).Flap5 and Flap15 are the normal takeoff flap settings. Some carriers choose Flap15 for all 757 takeoffs, some prefer Flap5 (like Finnair).And of course those, who prefer Flap5 for usual ops, will use Flap15 for noise abatement if neccessary.Flap15 can be selected instead of Flap20, if ATC chooses to make you keep the speed up longer.Normal sequence is, yes, 1, 5, 20, 30Go-around flaps is Flap20, single engine g/a Flap5.Single-engine approaches are always flown with Flap20 as well.Here's what I wrote in PMDG forum a while ago, regarding ref speeds, Flap settings etc. Should be good reading to everyone who thinks memory refreshment is in order.---------Here's how the 757 works. (And I strongly believe NG as well,someone correct me if I'm wrong)There's only ONE reference speed to be called Vref and thatis Vref30 or Vref. This speed is the landing reference speed.One should be touching down at this speed with flap30configuration. One should NEVER go below Vref, not ever. The reference speeds for different flap positions are alwaysMINIMUM speeds (Maneuvering speeds) for the presentconfiguration. For example, the maneuvering speed for FLAP1is the speed you must never go below in FLAP1 configuration. Ok, now here's something interesting as well. IF you are toaccelerate continuously, you can SELECT the next lower flapsetting 20 KIAS BEFORE the maneuvering speed for the nextsetting. This is because, when you select it 20KIAS before,you will be AT the maneuvering speed, when the flap settingis actually active. Flap transit takes time. This is done toenhance the climb profile, saves gas to make it simple :).Similarly, when you deccelerate, you CAN (although you rarelywill) select the next higher flap setting 20 KIAS before themaneuvering speed for the PRESENT setting. Again, the idea isto reach the actual maneuvering speed in the right config.Rarely ever are you able to maintain constant deccelerationthrough the profile, so this method is not widely used.The speeds for the 757. This table uses the "20KIASBEFORE" -rule in the acceleration part, because it isalways used, BUT uses the actual maneuvering speeds in thedecceleration part, because it is mostly used.passing ACCEL DECCEL man.spd:Vref (Vref30) FLAP30Vref+20 Select FLAP5 Select FLAP30 F15/20Vref+40 Select FLAP1 Select FLAP15/20 FLAP5Vref+60 Select FLAP UP Select FLAP5 FLAP1Vref+80 Select FLAP1 CleanSo here you can see, that we are selecting the LOWER flapposition 20 KIAS before its actual maneuvering speed whenaccelerating after takeoff, and using the actual maneuveringspeeds in decceleration. This is everyday practise.edit: sorry about the plain text format. Couldn't write thetable with HTML.----------regards,Tero

Hi,Spot on Tero!! The flap shedule is as you describe but the go-around is done at flap 20 and then you take flap 5 as you accelerate usually 1000ft above the airfield elevation. You monitor the speeds on the ASI speed bugs OR on the ADI speed tape which is where you will see the "F" (min manuev)and "R" which is the Vref30+5 min approach speed. All these speeds are entered in the FMC approach page. However I cannot get the "R" speed even though I enter it in the FMC?Regards Simmslot

Hi Tero, actually, I'm just transitioning to the 737NG at this time. :)The "R" is only shown as the Rotation speed if I'm not mistaken. The Ref speed is shown as "Ref" and is exactly that what you entered, not 5 knots above.
