OK - have to relate the story. Child of a friend asked me to look at his MSFS (don't know which model) as he had loaded the HKG scenery package.
Had a go in the Learjet. Max angle climbout through LaiYuMun Gap to 7000', chopped throttles, rolled inverted and pulled through with speedbrakes and then took gear and flaps and landed on 31. He was impressed - I was amazed at the authority of the A/P!
Proceeded to crash everytime since then. Bought and have since deleted the rubbish programme.
