Thanks! The 'unable next ALT' message will display when the FMS predicts the plane won't be able to reach the next altitude constraint in the flight plan. This is likely due to the rate of climb with the given speed in the distance between the waypoints. I suggest setting a slower speed/steeper rate of climb and see if it clears the message, or overriding the given altitude constraint for a lower one. As for unable RNP I'd guess this is a bug to do with the sim/plane not knowing the GPS position of the plane. Do you know when this pops up or can you replicate the error message as this will likely not allow precision approaches to be flown so should be reported to the dev team if it is a bug
Hi, I can try to help you out. Just a couple of questions, Which approach procedure are you flying? Or is it not arming for any of them? Is it just this plane it’s not working in or multiple planes? With the VNAV, I would first check that altitudes are programmed into the FMS by selecting the 'Cross' option in the drop-down above the flight plan and the manually selected altitude is set at whatever the next altitude you need is. The approach is a little trickier as there could be a few different factors, If its easier I could jump in a discord call and go through it with you to try work out whats happening?
Good clean tutorial. Straightforward.
Did you have to load your approach from the ils sheet?
Great Video! Could you explain what the message „unable next ALT“ means on the NAV Screen? I also get „unable RNP“ often…

can you do a video demonstrating a missed approach followed by a landing (with autopilot)
Hello! Yeah, next couple of videos will be Vision Jet basics then I’ll do a missed approach after that 🙂
I can’t get VNAV or APP to enable no matter what I do. Any tips?

all this time, I was landing manually
if you have no ILS approach - there's no other way than manual on approach
