The difference between mutual and dual is that:

mutual is to fly with your friend as the safety pilot, while dual is as per normal, to fly with instructor.

But the regulations for mutual sortie was no longer valid after the latest DA40 crash at KT few months back which caused one death.

There is no official release of the crash, but this is what the management told us.

The cause of the crash is human error. There were 2 planes "playing" dog fight at low level. Both were on mutual sortie.

However, one of the planes flew too low, then "brushed" with the trees, and the rest is history.

The other three guys (including the one in hospital), have been terminated.



So the rules for mutual sortie now is to fly with instructors as safety pilots. I feel that it's good, cuz at least there is someone I can refer to if I do the wrong procedures.

The bad thing is, we have to pay 50 bucks per hour to the instructor.
