embarking&disembarking with engine runing

[minipilot100]

Dear All

I have question about embarking and disembarking passenger of aircraft with one engine runing,is there any document and/or regulation related to this object or not?
is it legally approved that one engine of aircraft is run and embarking the passenger or disembarking?

best regards

It is done routinely on the ATR 42/72 thanks to a rather clever device called a propeller brake; engine no.2 (starboard) is kept running (at idle) but the prop is stopped. The engine thus acts as a pseudo-APU with no need for a real one in the tail cone - it's called "Hotel mode" (after a similar technique used on cruise ships). At most airports, however, a GPU is provided so that No.2 can actually be stopped (and so cut down on the noise). By then, however, PAX disembarkation/freight offloading is already underway from the port side.

Interesting to see from the outside the propeller stop fairly quicky whenever the prop brake is engaged!

The reverse is true on embarking/loading, when no.2 can be running already (PAX are saved a great deal of noise by the shielding effect of the airframe).

Not aware of any restriction on the use of Hotel mode during PAX boarding, but some ramp personnel object to working by the rear RH door for "Health and Safety" reasons when Hotel mode is used.

There is an approved Boeing procedure to board/service/fuel an aircraft with an engine running. I did this once in Finland when the GPU failed and we arrived in a 400 without APU. Pax off first, with no1 shutdown, crossbleed no1again and shutdown 2, then, baggage, refuel and crossbleed no 2 and shutdown no1 for pax boarding, then crossbleed 2 again and home!

Totally dodgy but approved on a very one off type basis. If you are looking at doing this to save time or money or some LCC type mental idea its a non starter.

Good Luck!

During quick turn-arounds when the old guy - rarely - or one of his minions - often - was in a hurry - we would routinely shut down #1 to ingress/egress passengers and/or contracts/money by the caseload/??? and leave #2 lit.

B200, mind you !

Drifting slightly, on the odd occasion with helicopters, we used to change crew and refuell with rotors turning.

Our airline (Beech 1900s in the United States) does this on a daily basis. Shut down #1, swap pax and paperwork, and you're off an running. I find it handy on occasion, (if we're just dropping pax at an intermediate stop), but don't like to do it much. If people are borading, then they must be briefed in a very loud cabin, it's difficult to communicate the basics like carry on stowage with them, it generally adds to the chaos factor.
