Max range flying

[zcrazyx]

Curious to see what everyones concesnus is on flying for max range, thought i'd try give it a go by flying around the map on the 4YA areo online server. Loaded 100% fuel, 100gal drop tanks and climed to 27,000ft using full power (i know probably shouldn't do that). Then i made it about 625nm total and had 25% internal fuel remaining. 

 

My question is what actually is the fuel consumption per hour at such altitudes and what are the best altitudes generally at for distance and speed.

And what is the absolute max range?

Speed for best climb is 150 kts at 2850 and +9. Climb for max range is 150 kts but with 2650 and +7 until 18'000 ft. 

 

Due to supercharger, fuel consumption stays roughly the same for a given power setting at any altitude. So without knowing which speed you flew, total consumption can vary between 70 and 110 gallons/hour.

But as an example, according to the charts, at 25'000 ft you get the most air nautical mile per gallon at 235 kts TAS (around 157 kts IAS, but manual recommends to increase that speed to 200 kts IAS or use what economical boost +7 gives) with 2100 RPM with mixture in weak. That gives about total 75 gallons/hour consumption. 

This is according to the pilots flight instruction manual. It's free to download on the web and the performance charts are in there.

Interesting, i know there's charts on the manual for it, i'll have to give it a look as i'm rather interested in seeing how long it would take to fly around the caucauses map using econ cruise. I shall endevour to share my findings when i get the time.
