Hi all,I have problems with VNAV discos after missed approach procedures. I start the missed approach with TO/GA which disengages the autopilot. When a positive climb rate is reached, I retract the gear and retract flaps as required. There

Did u re-set the MCP altitude ? so the Vnav can make its climb?

Uwe,I don't think the VNAV is the most appropriate mode after a go-around. I would opt to go LVL CH if not do it manually (The latter can be a handful though. :-)). The key I would say is to reset the MCP altitude to the missed approach altitude once GS is captured. This way you are prepared vertical-wise for a go around before final approach.Hope it helps,

Hi all,thanks for the first feedback, but the MCP altitude WAS set to missed approach/holding altitude. I know flight level change or manual flight would be more appropriate, but VNAV should be able to do the job as well, shouldn

Hey, Uwe:You are an FS Master (Magister!) already. Why on earth would you activate VNAV for a go-around? You would normally climb to no more than 3500' AGL for a GA. I was once on a real life GA up to 10,000' but that's because we had jammed slats on an A300 (into Seoul, Korea). I'd ditch VNAV in the sim and hand fly it up.JS

That's really irrelevant and not what he is asking.I want to add that I've had trouble with this also sometimes and it was usually due to a badly programmed STAR or pilot error.

Sorry, I should have completed the apparently irrelevant thought and said that if one were going to fly up to 10,000 as part of a MA, perhaps it might be worth using VNAV because that'd take a bit of time. But given the typical MA altitude, my counterpoint is why use VNAV to get to a measly 3000' AGL odd? I mean, it's about 90 seconds of climb before levelling off on a hold. Jonathan

Your not missing anything. I know what your talking about. Vnav should engage in Vnav Speed during the MAP climb then engage in Vnav Path as the MAP altitude is captured if the MCP and the FMC Altitudes are the same, but It don't. When you figure it out let me know. PMDG experts?Floyd

After flap retraction VNAV or LVL CH should can be engaged. SOPS are clear in this respect. For those who are performing a go-around, are you correctly exiting app mode? You have to push TOGA? retuned NAVs? or turn off BOTH the F/D and A/P? Best Wishes,[h4]Randy J. Smith[/h4]http://www.rawbw.com/~bdoolin/shinault/Animation1.gifCaution!
