September 16, 201411 yr Hi, after i passed the alt rest for 3000 at a waypoint after the MAP, i then was joining the TRANS back to the runway and it had a alt rest. of 6000 so when i pressed ALT INV the aircraft didn't climb. anyone know why? thanks. https://www.dropbox.com/s/lu39b4j56oixew9/2014-9-16_11-39-42-355.BMP?dl=0 Vernon Howells
September 16, 201411 yr I am thinking that the aircraft in VNAV mode still follows the altitude restriction in the FMS. you probably need to use FLCH to climb higher than a restriction in the FMS. Mark CYYZ
September 16, 201411 yr Author I'm not expert and hoping for an answer its a strange one. it works fine for me when flying a SID once you pass the waypoint with a AT rest you hit ALT INV and it climbs in VNAV SPD. Where is matt (spin737) when i need him lol Vernon Howells
September 16, 201411 yr Need a lot more information to figure this one out. What was the MCP altitude set to? What were the indications on the FMA?
September 16, 201411 yr I haven't flown a VNAV ALT equipped plane in a while. Can't you hit ALT INT to continue the climb? Matt Cee
September 16, 201411 yr This is going to sound stupid ... but, have you tried to reset VNAV (turn it off and on again) to get out of VNAV ALT?
September 16, 201411 yr Author I will have to redo the saved flight and get back to you! But i'm sure VNAV ALT was displayed Vernon Howells
September 16, 201411 yr Author yeh after reselecting VNAV this is what was displayed on the FMA - https://www.dropbox.com/s/zg1qrt0sfcox5hg/2014-9-16_20-46-58-851.BMP?dl=0 Vernon Howells
September 16, 201411 yr Iirc, VNAV ALT means that there's a conflict between the profile and the MCP altitude. However, I don't see it, and outside of changing pitch mode, altitude intervention is the way to get out of it. If you're sure you're clicking the spot (it's kind of hidden behind the rotary knob from the left seat), I'm out of options. :(
September 16, 201411 yr I never got further than a Citation before I went to pursue other employment, so I would give it some more time and hope other people will have a solution. Out of curiosity, which approach are you doing, where and how are you going missed, and which nav cycle do you use? E: And if you use a standard livery without changing options, which one is it?
