Hi, Thanks for the reply. I can confirm i handed over in a stable hover. I think the problem is that the elevation was about 4000 ft. George was climbing while I was increasing the R ALT however if you keep asking him to climb the value switches to Baro alt. In this case it was about 1500ft which is below the actual aircraft altitude. Therefore he goes from climbing on rad alt to trying to descend to match the baro alt despite being asked to climb.
Hope the explanation makes sense.
Best Regards,
Tom
