Crew Flow Problem - Climb

Featured Replies

Hi,I'm using version 1.4 and am having a problem trying to follow the Climb flow described in the user manual.item 4 states:If using the NADP1 profile: Call "SET FLAPS UP SPEED". however, for NDAP1 I only get the option "LEVEL CHANGE""SET FLAPS UP SPEED" only appears if I use NADP2.Is this an error in the manual, am I doing something wrong, or do have I a corrupt system?Thanks,John

Hi John,Can anyone else reproduce this either way? The file wouldn't be corrupt.I'll check the manual.Cheers,

:( :( Can nobody help?Bryan,Under what circumstances should 'LEVEL CHANGE' be commanded?It's not mentioned anywhere in the Manual (nor in Julio Cesar's Flow document).John

Hi John,I double check with Damien; he's the B737 Capt who wrote and tested the procedures modeled in FS2Crew.Thing to remember is there are so many different ways of doing it... some airlines would just hit VNAV at 3000 assuming their current FMC revision includes flap speed protection in VNAV.Cheers,

Sorry Bryan, I'm still not clear.If I use NADP1 should I get a "SET FLAPS UP SPEED" call?If the answer is yes than then I have a problem because I get "LEVEL CHANGE" insteadIf the answer is no then the manual is wrongThanks,John

Hi John,I'm on the road right now, I'll double check when I get home in a few days.Cheers,

Hi Bryan, were you able to investigate the issue with NADP1 not allowing "set flaps up speed"?I have the same issue, but found that if I use NADP2 instead I will get that call, but I'd much prefer using NADP correctly, because when I use NADP2 I then lose the level change command at climb thrust altitude.

I'll let Damien comment on this.Cheers,

Damien,I think the question is, in NADP1, who 'Sets Flaps up Speed'? the implication is the Capt (PF) as it's not part of the FS2Crew Flow for NADP1.John

Hi John,The issue behind it all pertains to the FMC Software version modeled by the iFly.Later versions of the FMC Software include Flap Overspeed protection while in VNAV.With that software version, you'd go direct to VNAV and not call "Flaps Up Speed" since there would be no point.Older versions of the FMC software, however, do 'not' include Flap overspeed protection while in VNAV.If using that software, you'd want to call 'Set Flaps Up' speed otherwise you could conceivably bust a flap speed if you weren't paying attention while in VNAV.I was under the impression the iFly modeled Flap overspeed protection in VNAV, but there's some contention about the iFly's modelling of VNAV.It's something I'm currently looking at.Hope that makes sense.Cheers,

My main issue here is why there is no call in NADP1, at the accel height of 3000, for the copilot to set flaps up speed. IIRC, in FS2crew NADP1 at accel height the only command is the flaps up call. Procedure wise, I would think the copilot (or PNF) is responsible for that task, since the pilot's hands are on the yoke (assuming autopilot is not on). There is a contradiction between the flows described above for NADP1, and the script in FS2crew for this procedure. Don't get me wrong, I love the automation that FS2crew offers us during this critical (and busy!) sector of flight, but I find the climbout procedure for both NADP 1 and 2 a bit clumsy, and does not take advantage of the assistance FS2crew's copilot has to offer. As I have seen in real life videos, the captain has his hands full controlling the aircraft manually, and has to delegate all MCP setting tasks to the co-pilot during manual flight. The PF is free to do use the MCP once the plane is on autopilot, but according to Boeing manuals (which I bought for the upcoming PMDG NGX), the PNF is responsible for ALL the MCP tasks while on manual climbout, and from my perspective some of those copilot tasks are missing in the FS2crew simulation. That is really what I'm trying to inquire about, and hopefully have addressed in a future update.Thanks

As Bryan Said,...."Hi John,The issue behind it all pertains to the FMC Software version modeled by the iFly.Later versions of the FMC Software include Flap Overspeed protection while in VNAV.With that software version, you can co direct to VNAV or VNAV would be armed on the ground and you would not call "Flaps Up Speed" since there would be no point.Older versions of the FMC software, however, do 'not' include Flap overspeed protection while in VNAV.If using that software, you'd want to call 'Set Flaps Up' speed otherwise you could conceivably bust a flap speed if you weren't paying attention while in VNAV.I was under the impression the iFly modeled Flap overspeed protection in VNAV, but there's some contention about the iFly's modelling of VNAV.It's something I'm currently looking at.Hope that makes sense.Cheers," Regards

Bryan/ Damien,Thanks for your replies. I think 767FAN and I are really voicing the same concerns, altthough he has put it a little better than me.I do understand you are trying to pick the 'best' course from the many different scenearos that could exist, but must agree this part is a little 'clumsy', and maybe doesn't follow majority of real world flows, who probably don't have/use the latest FMC VNAV software version anyway.For example, again with NADP1, the Capt calls 'Level Change", yet due to the flow layout cannot call for "Command A" until AFTER he's called "VNAV". Is this realistic?I trust you can find a better answer, because this mars what is an otherwise great program.Thanks,John

Hi John,Button control is limited in terms of its flexibility that way. Due the nature of button control, it's much more 'scripted'.If you want more flexibility, I'd suggest going for Voice Control... with Voice Control you have much more flexibility when it comes to autopilot commands during departure.Best,
