I have discovered that Jens' Avro Tudor IV seems to have somewhat longer legs than the record gives it credit for. Several medium hall flights (~ 1000nm) have yielded a cruising fuel burn average of some 1250 PPH which seems somewhat low.
Jens' North Star, also equipped with Merlin engines has typically averaged between 1600-1800 PPH in cruise, similar to the Lancastrian and York from Manfred Jahn and company.
After some trials (and error!) I settled on amending the fuel flow scalar on the Tudor IV to 1.35 from 1.00 which has had the desired result, increasing fuel flow in cruise into the 1700-1800 PPH range and so making the 2000+ nm trip from Santa Maria in the Azores to Bermuda potentially a bit more challenging.
As always however, I was reluctant to edit the aircraft.cfg not only out of respect to the author but also due to the laws of unintended consequences producing nasty results in other areas of the FDE. I have not noticed any as yet but...
Also I have been unable to source reliable fuel burn data for the Tudor so using other contemporary Merlin engined FS9 aircraft for models seemed like a plan.
So, how safe or reasonable is it to modify the fuel flow scalar and what FDE complications might arise? Thanks in advance for any advice or input.
