Is there any way to check the atmosphere settings for on and off line? Is one or neither a 'standard day'?

Hi Klem,

Here's what I got yesterday for the Spit Ia at sea level:

6.5 lbs, 2800 rpms: 245 online, 249 offline
6.5 lbs, 3000 rpms: 252 online, 253 offline

Did you try offline at 3000 RPM? Comparing different RPM settings is rather counter-intuitive.

I don't understand your question. Both online and offline are there, for two rpms. What's so "counterintuitive" about that?

WOW. I can't read. Sorry.

May I ask how does it compare with historical test data?

Hi Insuber,

Top speed for the Ia at sea level should be 283 IAS at full overboost at 3000 rpms (before the engine blows up LOL). If the boost control cut out functioned as it should in this sim and provided another short-term emergency speed boost of 25 mph, (253 + 25 = 278 mph), we'd actually be within 5 mph of Real Life data. IMHO, of course.

Hi Snapper - thank you! Do you refer to the 6.25 lbs or the 12 lbs boost?

12 lbs boost

I figure top speed is top speed ie. balls out full throttle-through-the-gate-gonna-catch-that-yellow-nosed-bastage top speed....even if it's only gonna last 5 minutes on a good day.

Others more learned than I (and there's lots of THEM!) may differ, and so be it. Me? I just wanna shoot 109's. Oh, and 110's, too.

LOL! With dangerous maniacs like you in circulation I would reduce the Spit's speed even a little more then!

He means that if we would have +12 boost in-game, which would add 25mph to the +6.25 in-game speed, the in-game speed at +12 boost would be within 5mph of the real life +6.25 boost.
