50-60km take-off runs, or taxi and T/O?
Tcas Climb,
<<<..About 1hour of this and we sucseeded in getting airborne, we were doing about 35 knots so it was about a 63 kilometer takeoff run..>>
Are you saying you took off at 35 kts?
I know nothing about Otters, but that seems a little low. What's the stall speed?
