Liquid fuel is not as dangerous as the vaporized variant (e.g. This risk is minimal due to grounding of both fuel truck and ACFT over the complete process. According to an AIRBUS representative at PPRuNe-Forums, it is no problem if you switch them on while refueling, however, it won't speed up refueling. Ilankrt, an A380 pilot for Luthansa once told me, that you could possibly switch them on before and while refueling in order to speed up the process. During fill make your flightplan and after inspection APU and passengers. So what does it mean for us: GPU / Batteries / FMCU / Loadsheet / fuel weight and fuel plan. normally, until the FCMC is not stopping the refuelling, Nothing is supposed to be done, but, thats the duty of the person in charge of the refuelling. in a perfect world, Nothing special is supposed to happen, except if some valves are having internal leaks, if there are no leaks in the tanks, etc. Īnd to the refuelling process: refuellings are managed by the FCMCs, depending on the qty required, the FCMCs will open and shut the refuelling valves, maintain balancing, etc. Īlthough possible many operators are not allowing to start APU, not only a fuel pump will be activated during the APU starts, but relays, exciters, etc. thats the most Dangerous time when the Aircraft is on the ground for so obvious reasons. "a lot of sparks are created in and around an Aircraft, thats the reason why, all AMMs have warnings at the beginning of the refuelling sections, normally, Nothing is allowed during refuelling except what is needed for the refuelling. Otherwise a simple brake down of the GPU would result in a big increasement of ground time and therefore more costs to the airline.īy the way it's aöready possible to refuel the A332 while apu is running by calling the fuel truck via the MCDU and then why not via the loadsheet? For example do you need more than half an hour to refuel your car?Īnd as electricity is one of the ground operations essentials I've to agree to Luke173 that it should be possible to refuel the 332 with Apu running. Well ilankrt, you can't compare refueling a car with refueling an aircraft. It is not a question of help but a simulation of reality ! What is your problem to click (right side down) on GP to get power for MCDU? So refueling with the APU on would really help hereĭu you fill you car with gasoline while the motor is running? The MCDU only comes to life with ground power (which I have to call through the non active MCDU) or with the apu on. I don't see how I should do my loadsheet before starting the APU: JAR: yes, I did this after starting the APU. May be You just trying to add fuel after start engines or APU? If so - This is not good idea.
