Tips
When doing the walk around on a high wing Cessna.
Step back out from under the wing before raising the aileron.
If it has been raining it will not pour water down your neck.
Also keep one hand on the trailing edge as you check the linkage and balance weights.
One instructor ATPL pilot at Stapleford had a news film crew passenger wiggle the controls while our pilot had his fingers in the gap !!!
Our pilot (through clenched teeth): "Why did you do that ?"
Passenger (innocently): "I didn't think it would do anything"
Holding the trailing edge provides a good degree of leverage against a gust of wind or a passenger that thinks the control yoke is for decoration.
