X-plane 10 mobile- "Canyon Tour" Baron B58 can't achieve passing grade

Question

I'm not sure what's going wrong here, game wise or myself. However I cannot achieve higher than a 76 on this flight. I achieve 100% on min flight altitude, but cannot achieve anything higher than approx. 60% on mean altitude. My normal flight altitude for this flight is between the range of 1900' to 1960'. When attempting to use maintain altitude button, the plane sets up in a very very slow climb, instead of maintaining selected altitude. Any help would be appreciated thanks

 

1. Start game
2. Choose "Challenges"
3. Select general aviation
4. Select Canyon Tour Baron B58
5. Fly designated flight path, obtaining lowest possible altitude
6. Finish flight
7. Fail to achieve passing grade

Answer 1

I have been unsuccessful in passing this challenge too. So, you're not alone.
