View Full Version : Bit of an oddity for me.

Now I've been around this game for sometime and I thought I'd seen most everything there is to see but I just got a bit of a shock and would like someone to expound if they would.

When I fly with pit off I fly with only the gunsight reticle showing never with the navigation dials. But last night I flew with them for the first time just for kicks and the speed dial has me completely perplexed. What is up with the velocity indicator in KpH showing values considerably higher than the speed bar, even when the speedbar is in the same units of measurement... KpH? http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif Is this a bug or is there something I'm missing. I'm stupefied that something so obvious has shocked me this much.

Was going to say maybe it's a TAS/IAS thing, but with the ASI being higher than the speedbar http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif. Sorry.

I don't fly with cockpit off but I would assume the difference your seeing is one is showing TAS (true airspeed) and the other is showing IAS (indicated airspeed).

The IAS will change depending on the altitude: the reason being that the instruments read differently depending on the atmospheric pressure.

The higher you go, the lower the indicated airspeed is in comparison to your True Air Speed (which is your speed in relation to the ground).

The speed bar always shows you your True Air Speed (handy for bomber pilots: without it they have to calculate it manually to operate their bombsights correctly), whereas that dial thingy in the wonder-woman view is simulating the dial inside your cockpit, Indicated-Air-Speed.

Take your aircraft low to the ground, and you'll notice the speeds on both dials correlate again.

You got it wrong Junko.
Speed bar and cocpit instruments show IAS.
Cockpit off dials show TAS.

That's the one.

Ah! My bad...not enough coffee this evening. Also, it's been a LONG time since I've flown with the cockpit off and the speedbar on.


Anyway...what they said http://forums.ubi.com/images/smilies/16x16_smiley-tongue.gif
