Technically yes - it is very important to ensure both tanker and aircraft are grounded to earth first prior to connecting the hose and/or bonding tanker to plane. Whilst you may be thinking in terms of small aeroclub sized planes, refuelling also applies up to the large commercials and these can hold big static charge, which needs to be eathed before bonding.
I don't want to change the answer you selected and the direction of this thread - I merely want to clarify an important safety point.

For the nickname...

So there you are really close to a taxiing 747. But if you were to look up and see a 747-400 flying overhead at max operating alt, how high would it be (in feet).
An easy one really

yup, most big commercial aircraft are bonded with the hydrant, according to our manuals at work, you don't earth aircraft or the refueller, only bond them, as it equalises the two, infact it is specifically stated that the aircraft and refueller must not be earthed, with out a lot of special conditions.
Dman, i was looking forward to those jafas, would have been nice to see the harriers!!In the ongoing battle between objects made of aluminum going hundreds of miles per hour and the ground going zero miles per hour, the ground has yet to lose.

Edit: Oh, in feet - 45000?
Close, but It needs to be to the nearest 100 ft for the choccy fish !!

Hmmm interesting I wonder why this differs to my experience. Mine is all military and in my time as a Tech I have refulled Strikemasters, Skyhawks, Orion, Hercules and 727. We always had to earth tanker and aircraft before bonding. If you did not do that, then they would not give you gas. Same went for Singapore, Aussie, Canada and US. Also I taught Aircraft Maintenance for 2 years and the same text book info was preached. I'm assuming that because of the use of hydrants with the large commercials and maybe some other means of earthing for aircraft is why you don't earth. Its hard to find stuff on the net, but most say to earth if a proper earth point is available (which we always had on aprons) otherwise bonding is more important. People pay lip service to this, but there have been plenty of cases of aircraft destroyed by static electric discharge during refuelling. At the end of the day its about following the procedure laid down for your organisation.
