ATR & Hotel Mode
I agree that the APU maybe the more cooler method but part of that reason is that it can be left going for the whole turn around, hence has a longer period to try and cool the aircraft. In hotel, it needs to be shut down for servicing, fuel and unloading the rear of the aircraft. It is generally started only 5 sometimes 10minutes before departure so with a full load on a hot day it is already way behind trying to cool down a 30+C cabin. The complaints we get from the cabincrew the most is with a full cabin the air con struggles to keep it cool.
ATR92
I know a little about this only in the form that with our fleet soon to be up for renewal ATR have been briefing our managers on the replacement for the atr 500/600 which i think is to be designated the 700 (high70seats) and the atr92 (90+ seats). Both clean sheet designs.
Same general layout as the current atr but with a major change being that the baggage/cargo holds will be placed underfloor. Still the gear in pods from the fuselage. Passenger entry will be via a front door. Not sure if it is going with a prop brake or not?
The target design speed is a cruise TAS of 320-330, so I guess an indication that atr conceed a little more speed would be better.
Will incorporate all new A350/380 technoligies. Will have a new technology anti/de-ice system which won't require bleed air. Hydralulics will be individual power packs at each point which requires them. No central system.
I am pretty sure that it is going to be side stick, so fly by wire also.
Will try and find more out but there is nothing on the net yet as is all still concept and planning at ATR.
Cheers
