Ditching
Avroliner, take care.
Even if you don’t fly your Avro RJ or BAe146 on long over water legs still think about the destination airfields. One slip at LCY , Genoa, etc. !!!
Structural integrity is important, but don’t think that you will get time for the ditching checks; remember the 737 that went off the end at LaGuardia.
The 146 ‘wheel to wingtip’ angle is about 18 deg. The aircraft is designed to float, and with the rear doors at water level the bank angle would be approx 10 deg, which includes half submerging one engine.
I referred to the evacuation requirements earlier; the 90 sec timing only applies to the certification test. The time does not vary with aircraft type, the number of passengers carried dictates the number of exits required in order to meet the time requirements.
