Hi anyone else had problems commanding ALT INTV? Have flown the tutorial twice and this clickspot doesnt seem to work? I have had to increase altitude using LVL CHG. Also is there any way of 'disabling' the VC yoke so it is always in the down position? Many thanks for any help :-)

*bump?*

That's strange. I'm having no issues. The click spot has been extended somewhat because it's hard to see from the captain's view.

Are you remembering that you need to press it to clear every alt restriction in the CDU up until your selected MCP altitude? The only problem I've run into with it so far is that if I've already passed an alt restricted waypoint, and am now higher than that restriction through using vnav/vs, I'm unable to then use the intervene function to clear those restrictions and engage vnav. Seems the only way to proceed in vnav is to either wait until your altutude is lower than the FMC calculated waypoint alt, or to manually change the altitude for the current leg in the CDU. Presumably this is just my bad habits, as I have faith that PMDG would have this modelled correctly.

Hmm it seems to work here. Very convenient to be in VNAV ALT during a temporary ATC climb restriction and just having to press ALT INTV quick to resume climb after having reset MCP altitude. Great stuff, works beautifully.

That might just be it! Will try again this evening Thanks for all the help guys
