Atr's 600 series hotel mode VS bombardierq turboprop nextgen APU

Tue May 16, 2017 1:39 pm

Guyys overall ATR has the more economic product. But what about the noisy hotel.mode that everybody hates at all airports I have been at? Isn't a new generation APU just a better tool for health of employees and savings in use of expensive ground equipment?

Not to talk about the hazards of a running hotel mode during baggage loading and fueling. You shut it down 8 out of 9 times on ground during normal ops .

The Flying Engineer has a nice comparison between both the turboprops.
An APU will always be preferred over the Hotel mode, but since ATR has designed the aircraft with hotel mode to replace the APU, they will stick to the plan.
I hope they come up with a higher capacity turboprop with an APU.

Agree . nothing can replace an APU.

Well based on sales I dont think the Hotel mode is a big factor the ATR is outselling the Q400 by quite a large margin.

As I recall, an inoperative "Hotel Mode" was a piece of this accident:

https://app.ntsb.gov/pdfgenerator/Repor ... l&IType=LA

Without a functional prop brake (and no APU), the crew was running the right engine with the prop feathered. The flight was normally an EMB-120 - WITH an APU - so some believed that the employee wasn't expecting an spinning propeller when she went towards the right main gear to pull the chocks.

The ATR is much cheaper in list price. And 30% less fuelburn. That's the winner right there.

And they gain those 30% and lower list price by saving, among other things, the APU. APUs are heavy and really expensive, and is yet another maintenance item that is required to work before every flight. Fitting an APU down in the tail also means that you have to plumb the aircraft with a more complex fuel system that leads all the way there, along with fuel pumps and all the electrical wiring and so on. As it is today, the entire fuel system of the ATR is pretty much found in the wings, centre fuselage and gear fairings.
