This
is an awkward question – I haven’t seen it yet in the UK, but it certainly has
appeared in other countries.
Also,
I suspect we might see it here in UK sometime soon –
Cruise
overhead to overhead 3hrs 12mins
Fuel
flow: 23 in.HG (or full throttle), 2300 RPM, 20°C
lean. FL70 ISA +20°C 68.75PPH (CAP 697 section 2 page
6)
So,
TRIP
FUEL = 3hrs 12mins + climb correction + descent correction
= 3hrs 12mins + (3mins + 10
lbs) + (10mins) = 3hrs 25mins +10lbs
= (3.417 x 68.75) + 10 = 245lbs
BLOCK
FUEL = Start up + Trip + Reserve = 10 + 245 + (30% x 245) = 328lbs
