refulling with engine running
Somebody knows if there is a refueling procedure (for B737 ) with one main engine running?????.......
I mean Boeing procedure or military procedure or for BBJ ??
or a special company procedure approved ???? or even other type trasportation-cargo airplane ....
tks............

Fuelling With Engine/s Operating(Hot Refuelling)
Link Here
The FCOM manual will more than likely have a procedure laid down for hot refuelling, including whether it is allowed or not.
I should write that please do not carry out hot refuelling procedures unless permitted by your organisation. If hot refuelling is permitted I am sure that your organisation will have a procdure in place. The procedure is also likely to have variations for each version of B737

Can I ask why a civil a/c would need to perform a hot refuel?
Would it be due to landing at an airfield that doesn't have the required GSE to support the a/c type whilst said a/c has a U/S APU?

On a slightly different note back in the 70s the powers that be were asked to provide a procedure for refuelling 25 Kva aircraft generators whilst they were running. The usual things such as bonding and diesel powered rather than petrol were mentioned but the last bit was it must not be supplying power. It begs the question, why would you want to refuel it with the engine running if it was not supplying power!!!
At a guess, i would do it as follows..
Aircraft arrives on chocks.
No 2 Engine Shutdown
A/C Steps to the R1 door
Refuel Connected & Started
No 2 Engine Oil levels checked etc / RH side of a/c walkround carried out.
Refuel completed & Disconnected
Crew member on board, R1 a/c steps removed, No 2 engine started.
No 1 Engine Shutdown
A/C Steps to L1 door
No 1 Engine Oil levels checked
LH side of a/c walkaround carried out
Crew member onboard, L1 a/c steps out. No 1 engine started.
Taxi out.
The key here would be that the minimum amount of people around the aircraft, with fire cover in attendance

Moi,
You also have to include the following: -
1/ Park in location away from anything that could be destroyed if there were an explosion. Turn off engine on side of access.
2/ Deplane all unnecessary persons to safe location
3/ Establish exclusion zone (500 m diameter) minimum
4/ Ensure attendance of briefed and trained fire personnel with fire equipment (tenders and hand extinguishers)
5/ Ensure aircraft chocked
6/ Ensure aircraft is earthed
7/ Ensure access to fueling points is safe and will not produce fod
etc...
When embarking pax and crew after refueling complete, ensure engine near to access point is not running, unless it is considered safe to embark with engines running.
The above assumes that all persons are briefed prior to task taking place, as to hazards, risks and tasking. Tool Box talks can be emailed to those involved at the airfield prior to arrival. Take spares with you and brief them again on arrival. If translation required, ensure a translater is there (with the ability to translate technical speak).
Any crew remaining with aircraft must be properly clothed, and must have a safe route of exit.
All doors shut whilst refuelling takes place can save anyone that remains aboard. If there is a fire they can exit by the nearest "safe" exit.
I recommend that you take fire safe hand held radios with you so that all can communicate. probably four or five sets.
I could go on, but hopefully you will have some ideas from my notes.
Oh yes, think about a minimum of two tenders. One to attack any fire and the second to keep safe route of exit clear of fire and also any leaking fuel that flows towards safe exit route and fuselage
How are you checking for fuel contamination? How are you checking for accuracy of amount of fuel delivered?
If you go to the Following Link, there are some useful pointers. I realise it is an Airbus document, but much is relevant.

There is a load of waffle about hot refuelling. I was refuelled rotors running both miltary and civil for some 43 years. During all that time I never saw or even heard about a fire breaking out when refuelling with jet fuel.
The onlr fire I know about was when one was deliberately started when making a Royal Navy training film involving refuelling a piston engined Whirwind.

I doubt the hot refuelling regs for civil airliners require said refueller to climb over a Nightsun and squeeze down the side of an in-use engine exhaust to carry out a refuel though!

Fareastdriver, on the Wessex they stopped us being on intercom when doing engine running refuels as it had been worked out there was a serious amount of static about that could case an explosion, the fact that you were open line refuelling next to a hot exhaust didn't seem to bother them though....
Now Wessex refuels in the hover, that was interesting fun..
Sorry for the drift, back to the topic.

Not exactly refueling with engine(s) running - but refueling always goes along with some "danger".
I also wonder about the frequent spillages through the vent tanks on the B747s.
If the spillage meets a hot surface one day... PUFF...!

Engineers are valuable.
I've never seen Osprey BA in 'rotund' sizing, which might be one reason I guess.

Every day millions of untrained operatives put highly inflammable petrol in their cars. I have never heard of a forecourt fire. I understand that they have been, but not very many.
Basic aviation safety (or any type of safety) reduce risk to ALARP. Not hard just needs sensible precautions and a proper RA.
First question is 'Is it really necessary to engage in this activity?'
