Indeed. This is why it is quite pointless comparing fuel burns of jet engines when the airframes are different. Mine is nearly twice that of Dave Johnson's big Vulcan because he is, on average, using lower power settings reverting to full power for those big climbing turns and gliding at low power thereafter.

Remember, too, that wing-loading is a factor; I have 45 sqft, Dave has something like 70sqft. Take-off weight of the Hunter is 170 lb i.e. ~3.7 lb/sqft, the Vulcan is 150lb i.e. ~2.2lb/sqft - a significant difference.

Being a good Lancashire lad you know '--- tha get's nowt for nowt ---!'
