http://www.simhq.com/simhq3/sims/features/a10history/ Comments on these performance numbers? And I have never heard of this stall horn as far as "a continuous tone when the aircraft is at its best performance" is that for reals and is it actually usefull for turn performance judgment? <BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote> The A-10 has a very good instantaneous turn rate, but the sustained turn rate isn’t as good because the aircraft does not have enough thrust to maintain its speed. However, it is still capable of more than 15 degrees per second maximum instantaneous G just prior to wing stall. There is a stall warning system which will warn the pilot that he’s getting close to a stall by sending out a ‘chopped’ tone. This system will also give a continuous tone when the aircraft is at its best performance, and for the best results you should hear that tone without getting to close to the stall point. The aircraft itself gives little stall warning but it has the earlier mentioned warning tones and when the gear is down a stick shaker will warn the pilot of impending stall. Stall speed depends on a lot of things, but without flaps and at a weight of around 30.000 pounds it’s about 120 IAS. Once in a stall, the A-10 has excellent stall/ post-stall/ spin characteristics. To get out of a stall the pilot has to reduce the AOA to below stall warning and do the obvious things like retracting the speed brakes. Overall it is a very easy aircraft to fly, which is good because a pilot’s first flight will be a solo flight. Sustained load factors at 150 knots 2.29G Sustained load factors at 275 knots 3.26G Instantaneous load factors at 150 knots 2.34G Instantaneous load factors at 300 knots 5.0G Stabilized 45 degree dive speed 260 knots Take off distance at max gross weight 3850feet Sustained turn radius at 1500meters/5000 feet with 6 mk82s No flaps 200 398m/1305f 250 568m/1864f 300 792m/2598f 20 degree flaps 130 306meter/1003feet 150 296meter/972 feet 170 358meter/1176feet <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote> "We sleep safely in our beds because rough men stand ready in the night to visit violence on those who would harm us".

Yes it is, we Have about 15 Differnt Tones in the F15 Alone. Some also Cycle in frequency at the gain rate of the AOA limits. When ya get to Double Beeper, its time to think of a better option <img src=icon_smile_wink.gif border=0 align=middle> "The power to Destroy the planet, is insignifigant to the power of the Air Force----Mudd Vader

Circa 1986 or so?

I think you are talking about the chop tone (stall warning) and the steady tone (peak performance) that are emitted at certain a given AOA. Yes they are real and we check them on the preflights with the pilots. It is part of our launch checklist.

I DO, Infact theres been a few more that have done the same, one of the reason there are 20 Blocks of F15A's Much Was learned (read Unfucked) Block 1-7 are non airworthy because of this, and it is a rarity to see anything Younger than a '76 F15A. I believe Otis and Oregon are flying the last of the oldest. 90% of the gateguards are busted Winged A models. The rule is not to exceed 20AOA and also at 40AOA you can expect a Wing FOLD or Full uncommanded roll, departure with zero input. Macair did a really good Job with the Jet, Its one of the few that aerodynamicaly can exceed and sustain more than the Pilot or the jet can sustain. F15 in the begining was a 8000HR airframe NO Shit that was extended to 12,000 In the C or so. The Mudhen is double that. Allot of dudes burned in or Punched. Lots of Artifacts from Sosterberg to Bitburg. "The power to Destroy the planet, is insignifigant to the power of the Air Force----Mudd Vader

Don't tell me you consider hitting the lift Xducer with your fingers an ops check do you? <img src=icon_smile_wink.gif border=0 align=middle> Just a queastion too, when your doing your checks just what angle do you set your AOA for tones?

Josh, I'm glad to see that the 75% TO review did not ruin your sense of humor! Let me know if you still want the NSN for the 205 remote. Kungfu "Take what you can...Give nothing back!"

I thought I might get that response HAWG166. And kungfu yea, I'd still like to get that NSN. BTW thx for the TVM procedures, I'm building that extention cable now before I pitch the idea to QA.
