What are the drills in a glider for ditching?
One type I fly, a LS4-b, says that on a test-ditching (!) that was made with the gear retracted the sailplane was completely submerged on landing. The procedure therefore is lined out as:
- Extend gear
- Open parachute straps
- Land at minimum speed Protect face against the possibility of the canopy breaking using left arm
- After landing undo belts
- If canopy still intact leave airplane under water. This may only be possible after the front fuselage has fully filled up.
This is a straight translation from the german POH.
I find this quite sketchy about how to actually leave the thing but very detailled on which arm to use to cover your face. Other types I fly are very similar, though not using even so many words as this one. They all stress the extended gear, however.
An older LS-4 does not mention ditching in the POH at all. Maybe that was written preceding the test mentioned in the other book. I am not certain from the wording that that was a deliberate test at all, maybe just an accident to learn from.
