View Full Version : Cruising Speed & Formation Flying?

While setting up a FMB for formation practise I realised that I don't know the cruising speeds for any aircraft.

For instance, I'm starting with P-40s.

Cruising speed should be a fuel effecient speed obviously, but is it safe to assume cruising speed is a throttle at 50% at say 5k high in level flight?

I bet every aircraft has it's own cruising speed unless in escort of bombers.

Is "Military" power cruising speed or boost or AB or just 0-100% throttle?

And lastly, let's say this flight of P-40s is in formation 'hunting' the enemy. Would that flight be at a particular 'cruseing' speed as well?

Any pointers or links? Thanks for your help & time!

For the game, anything up to 80% throttle would suit your purposes. Higher than 80% makes it too hard for both AI and humans to join formation.

Most of the default missions use between 50% and 65% throttle for cruise. I tend to choose a speed that gets the aircraft where I want them at the right time. Unless it's a really long fuel critical mission, that works fine. For playability, very few missions are designed that long http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif.

Well, FWIW, I tried a formation practice using the 'official' cruise speed of a P-40 and found it a bit easier than other speeds. (237 mph or 378 kph).

Thanks Tully for tip there. That USAFM link has a lot of additional info about many WW2 planes not in the stats of the View Object feature in IL2/PF including cruise speeds, etc. Check it out!
