Glad to hear people are enjoying the mission!
I considered putting the scoring criteria in the mission but decided it would take too long to explain and be a lot of reading :P. So here it is, for those who are curious. Each second, you get one "point" for being within the following limits:
-4 deg < bank < 4 deg
-4 deg < pitch < 4 deg
speed < 1 m/s
0 m AGL < height < 6 m AGL (10 m for third test)
aircraft within assigned hovering area
(if applicable) within 5 degrees of assigned heading
There are no checks for rotational speed in the second test, or movement speed in the third test. As soon as the instructor tells you to change heading or position, you will stop accumulating points until you're stable at the next heading/position. So the faster you do it, the better, except that will likely make it more difficult to re-stabilise yourself. The scores are set to give you roughly 5 sec to change heading in the second test, and roughly 10 sec to move between each container in the third test.
That's a good find, I am going to go check those out now.
