What in the world is Hotel mode @Mooney in Oz?

Hello Brad.  

Hotel Mode is what ATR call their prop brake system that is applied to the No. 2 engine only. The crew flick a switch on the above panel in the flight deck which activates a hydraulic brake that stops the prop from spinning even though the main turbine continues to spin allowing the engine to do the job of an APU.  It really is only used  at engine start up and shut down as it does have it's limitations - it is as loud as hell and cannot be used when a strong tail wind is prevailing as it can cause an overheat condition in the nacelle that will trigger a master caution in the flight deck.  A normal APU on a jet or Dash 8 is nowhere near as loud and are on most of the time.

SAAB 340's also have a Prop Brake system (don't know what SAAB called it), but most if not all were disconnected permanently due to resultant engine issues.

ATR have the Pratt & Whitney free spinning engines and SAAB have the General Electric free spinning engines.
