APU Use
Nunc est bibendum
Not sure what the regs say but I would be surprised if an aircraft so equipped could operate without a serviceable APU.
Were air con not available and fuel critical to the extent of not being able to run an engine then plan C is needed. Full aircraft, temp in the 30s, and no air would have the temp close to 40 before engine start. Heck, the cabin can be in the high 20s when it's empty, no air and only 20 degrees outside.

Hot refuelling is only permitted under strict conditions, to get one to a maintenance base, should the APU fall over at an out-port.
As an aside, i've run an engine for air-con during boarding with no issues from the aerodrome operator.

Righto keg and Captn Claret et al. Thanks, that clears up my query.
I guess my original worry was hearing that an airline possibly had pax sitting on the ground sweltering without air. An airline would do that at it's own peril I suppose.
There's been plenty of publicity about leaving pets and babies in cars on hot days or any day for that matter and the potential for overheating and even death.
I don't imagine that APU's break down that often anyway.

If you observe O H and S there would be no physical reason why a 744 or indeed any Jet couldn't refuel on the right side while 1 or even 2 Engines were running on the left side.
Whether operator and or local regs allow for it............another story.

We used to hot refuel on the 146 when the APU was U/S.
... mind you - a three sector day like that in tropical heat was a loooooong day.
- Arrive on stand
- Shut down engines 1,2 & 3 (leave 4 running)
- Offload passengers, cleaners get on
- Cross-bleed start engine 1, shut down engine 4
- Off load & on load bags, hot refuel
- Cross-bleed start 4, shut down 1
- Cleaners get off, new passengers get on
- Cross-bleed start 1,2 & 3 and depart

G'day Checkers,
Ansett must've operated the Super 146. Ours had/have electric starters.
G'day to Reddo too.

There is/was no written guidance in my organisation re boarding with the APU u/s and cabin conditions too extreme. How to manage it seemed to be left to the PIC. Having said that, I've never heard of a PIC having pressure not to run an engine during boarding, even to the point of not commencing until after the baggage (right hand side) loading was complete, to allow the right engine/s to be utilised.
If on an aerobridge, I'd liaise with the ground staff & engineers, and usually start the left engine/s.

Shows you how long it's been 
- and as an FO, I didn't get to start engines
Cross-gen start, I guess
Reddo would say "hi" - but she's out earning a crust, like a good woman She was "ramped" today, as well
