bleeding off vapp speed to vref +5 - PFPX

[scandinavian13 5,192]

Well it was set at V2 153 per the FMC?

 

What amount of flaps was that V2 calculated with?  Were you following the speed/flap profile on the PFD?

[Driver170 42]

Flaps 1

 

V2 153

 

I was following the FD, maintaing V2 + 20

 

Engaged LNAV at 400

 

Engaged CMD A at 1500 thrust reduction height

 

Engaged VNAV at 3000

I'm on my iphone, so it's a bit hard to see, but what's your weight? Are you doing NADP-1? Why are you in LVL CHG? Or is that a reversion? Is this a Flaps 1 takeoff?

[Driver170 42]

i should say a flahing A

 

its happening at 1500 thrust reduction height?

 

i was flaps 1 

 

62.1 t

 

it just goes into LVL CHG after i select CMD A i don't select VNAV till flaps are up.

 

I was following the FD, maintaing V2 + 20

Engaged LNAV at 400

Engaged CMD A at 1500 thrust reduction height

Engaged VNAV at 3000 

soon as i bug up speed to 230 it stops flashing?

oh sorry yes NAD 1

[Spin737 102]

How about you try it with VNAV from the start.

 

The speed tape is bothering me, too. It doesn't seem right - like you're too heavy.

[Driver170 42]

soon as i roll the speed bug up, it goes away !

 

well i'm trying to follow a policy engage VNAV above 3000 agl ....

[Driver170 42]

Still get that flashing A on takeoff without VNAV engaged. The flashing A comes on about 1500 feet thrust reduction height!

At 16 min its at takeoff roll, watch for the IAS window he gets the flashing A

I didn't watch the whole thing, but something about his bugged speed and/or AP settings seems off. In fact, his A/T isn't armed during takeoff. I don't own the 737-series AOA lessons so I'm not sure why.

 

But if you look closely, his speed bug is slightly inside the "stall warning/stall imminent" zone on the speed tape. That's why he's getting the flashing "A" on the MCP.

 

I may be wrong, but I'm pretty sure that if that's happening, then it's a configuration issue on your end. Now, that may be done on purpose (Although I don't know why someone would do that) or it may just be an error/oversight.

[Driver170 42]

But i'm following everything i'm suppose too, topcat and pfpx!

 

Is it cause i'm not maintaing V2 + 20 ? And i'm under speed or maybe wrong flap config?

 

I don't think anyone will know for sure as no one has ever flown the NG in real life! I could take it to the pilots forum called pprune but prob get laughed at lol

False.

 

This guy \/  \/  \/  (Matt) flies it.

[Driver170 42]

Right i see, i didn't know!

 

Its a weird one with what i'm experiencing, unless TOPCAT is totally messing up the performance calculations.

How?

[Driver170 42]

Not sure! I'm hearing its possible that i'm too heavy but i'm within my limits. Also i should try flaps 5 but why? Its what TOPCAT is calculating.
