High Level Incremental Fuel (HLI)
Hi,
Can someone please explain to me the purpose of High Level Incremental Fuel (HLI)?
Was it just a case of squeezing a bit more fuel in all the tanks above their normal refuelling levels to increase the fuel load for maximum range, possibly something like LHR - BGI with unfavourable weather conditions?
How often was it used and were there any special operating procedures in place when it was used?
Many thanks,
Steve.
