This isn't so much a problem as a mystery for me, the flaps 5 retraction bug on the PFD only shows up sometimes during take off, I can't figure out what I'm doing different during the takeoffs when it does appear and the takeoffs when it doesn't.

If you're taking off with Flaps 5, it won't show because you obviously don't need the flap retraction speed for Flaps 5 if they are already selected. All that matters for you now are the Flaps 2, Flaps 1 and Flaps Up speeds. The Flaps 5 bug will only show when you takeoff with a flap setting greater than that, like 10 or 15, because in this case you will need to know when to retract the flaps to 5. Don't know if it makes much sence, but I hope this helps.

I guess that makes sense, thanks

If you take a closer look at first part of the FCTM, you'll see those indications are actually flap manoeuvring speeds. This means 30 deg of bank with 15 deg overshoot before stall with that flap setting (I don't have the FCTM is front of me to double check the deg). Flap 1 is selected at V2 + 15, flaps UP is selected at the flap 1 manoeuvring speed. That's how I read the FCTM anyway. Mark Austen

Flap 1 is selected at V2 + 15, flaps UP is selected at the flap 1 manoeuvring speed.

No, it is simpler than that: Select flaps 1 as your speed increases above flaps 1 maneuvering speed. Flaps up as you accelerate above flaps up maneuvering speed.

Based on the FCTM, flaps UP are selected at the flaps 1 manoeuvring speed, which makes sense, as you would want flaps to be UP at the flaps UP manoeuvring speed. Is the procedure you mention above an airline SOP?

I think this is not completely correct - as far as I understood the FCTM Your speed is increasing and current flaps are at 2.When the speed hits the Flap 1 maneuvering speed bug, you select FLAPS UP provided you are accelerating. At that moment you only have adequate maneuvering capabilities (15 deg of bank with 15 deg overshoot before stall ) until you reach the flaps up maneuvering speed bug (then youhave the full maneuvering capabilities (30 deg of bank with 15 deg overshoot before stall ) For flaps extraction it is the same principle: you set the speed bug to FLAPS UP maneuvering bugJust before the speed hits the FLAPS UP bug (1-2 knots above) - here you have full maneuverability - select flaps 1then reduce your speed to flaps 1 maneuvering bug.When speed stops (1-2 knots above) at Flaps 1 bug then select flaps 2.Set the speed to flaps 2 bug and repeat. So you basically slow down from flap maneuvering speed bug to the next flap maneuvering speed bug This is how I understood FCTM. Maybe someone with RL experience in NGX can confirm if this is a proper way or not. anyway, hopes this helps

Nope, it's more complicated than that. ;) Mark has it right.

Mark has it right: look at pages 3.32 - 3.34 of the FCTM.

Mark is indeed right - I stand corrected

One thing I do not understand is: What does "overshoot" mean in that context? Can somebody explain that to me?

"Overshoot" is extra margin in the bank. For example, the FCTM defines the flap maneuvering speed as "These speeds guarantee at least full maneuver capability or at least 40° of bank (25° of bank and 15° overshoot) to stick shaker within a few thousand feet of the airport altitude"

Allright.Thanks a lot.
