What is that beeping noise?

[Ricco]

Hi, I'm trying to like this game but I'm having so much trouble. First, I need to find out what that beeping noise is when I start up the training missions for the SU-25T.

When I get the electrical online, and am about to turn on the lights, an extremely annoying and urgent beeping starts up, and I'm so insanely into finding out what it is that I totally give up trying to continue the training.

I know I must complete this training because everytime I attempt to take off in the campaign mode, the first thing I notice is that I can't get up to take off speed without twisting the steering, which always ends up in a crash. When I do manage to get the crate in the air, after several crashes and restarts, I can never seem to keep the plane in the air after pulling up the landing gear and retracting the flaps, I can fly alright, but can never seem to make it to the front line. What the???

Is this game rigged or what can I do besides just keep trying over and over and over. I must be doing something wrong. Any suggestions would be appreciated at this point. I'll just turn the sound off until I can get it right.

There are 2 options. It is high AoA indicator or RWR.But I guess the 1st option. It is caused by wind which is moving with AoA sensor up and down. Once you will get enough speed, it will start working as it shoul'd.

AoA or Angle of Attack or so called Alpha indicator indicates the angle of attack of the wings against the wind. If you reach too high alpha, the AoA will warn you by fast beeping. It is very important tool because if you exceed the AoA limits, the aircraft will fall to stall. To avoid high AoA you must pull stick a bit to get nose a bit lower and/or increase your speed. You can aslo try to use flaps to make more lift but they also increases air drag.


You can turn off this warning sounds by hotkey shift+n (not sure if left or right shift)

Right shift + N ^

At the take off, the aircraft is steering because there is crosswind or your twist is too "sensitive" so it works when it shoul'd not. You can try to adjust axis curve to make it less sensitive at the neutral position. But the best but more expensive solution is to get flight rudder pedals. Saitek do some but they are not enough good. They have problem with their lifetime caused by plastic parts. You can try T-flight rudder pedals by thrustmaster or if you want something "pro", you can buy MFG crosswind, which are just the best pedals I ever had. http://www.simhq.com/air-combat/mfg-crosswind-pedals.html

Thank you, I'll try your advice. The flaps seem to be fine, I know how to adjust for takeoff and such. It's just frustrating that I can't figure out what it is exactly, and why it is. It seems like an important warning, but warning of what? There was a truck driving by just as the signal started, but then it happened again when I was just sitting on the starting point and all was clear. This whole scenario is playing out in the training mission for the first one. Starting and taking off.

I'll try the shift+n keys now to see if it works.

Thanks, I've tried rudders in the past and could not get into the spirit of them. The stick steering works fine if I get control before going too fast. I guess they want us to feel the realism.

This is how the AoA sensor looks: http://www.aircraftmech.com/pics/aoa.jpg
When you go too slow or when you stay in windy conditions, it is moving up and down and not working as it should. So it can indicate too high AoA which starts the "alarm".

That makes sense, however the only time this alarm goes off is right at the beginning, when I'm turning on the power and lights, and closing the cockpit, then a truck drives by, and the alarm goses off for a while, then stops, and might go off again if I just stay in one place.

It makes absolutely no sense to me. I'm on the first training mission (start and takeoff), the beeping hapens when I'm just sitting at the start place, power on, waied for the truck to go buy, beeping, truck gone, beeping... then silence for a while, then beeping. Sometimes it beeps for a long time then shuts off. Sometimes it's a few quick beeps, then off again. I can find nothing that seems to trigger it. Sometimes it is silent. I just wish I could figure out what it is. Shift+N does not work. Nothing works except getting on with the mission.

That's wind, as the wind blows over the wings the AoA sensor goes mad. It's normal

[Ricco]

Isn't there any indicator light of some sort? Been looking all around and can't find any indicator on the dash. I now know it's not the RWR. Those beeps are completely different.

Record the beeps and put it on youtube. Use cell phone camera or audio recorder if you have to.

HERE[picload.org] is the picture how the AoA sensor on SU-25T looks Because it is not animated in SU-25T, I will record it on another aircraft.

HERE[picload.org] is shown where is the AoA indicator located in cockpit

HERE[picload.org] you can see the situation when you can here the beeping in cocpit. When the AoA indicator indicates exceeded AoA. Until your airspeed is lower than 100kph, the AoA indicator is not working correctly because the AoA sensor is moving in the wind up and down like the weathervane.

HERE[picload.org] is explained, what is AoA.

EDIT: here is the video: https://youtu.be/MgbBXBc_EIg

I'm not terribly familiar with the Su-25/Su-25T but I believe the AoA warning light is a Greek alpha that lights up within the AoA gauge itself on the top left of the dash. So just down and left from the center of the hud (or gunsight in the case of the vanilla Grach).

It shouldn't really be a huge deal though. Most noises besides RWR should be gone by the time you're off the ground and flying level. RWR can be set for lock-only (which I don't recommend), or simply turned down to an acceptable level (much much more preferable.)

Most master warnings can be reset with right shift+N. I don't think it disables any actual systems, it is just an audible warning reset.

If none of this is the culprit/none of this works for the sound you're talking about, gonna need to see some evidence of what this sound is so we can figure out where it's coming from / why it's happening.

Sounds like you're having problems with takeoff though, which honestly, if I were you I'd just mute your game audio, blast some sick tunes and play over and over on a free flight map from takeoff until you can nail it every time. Takeoff should be the easiest part besides maybe level flight. Simply follow the takeoff procedure and you should be golden.

Flaps down (depending on load), hold wheel brakes, and throttle slowly to 70 or 80% RPM (I think it is? it shouldn't matter that much.) When RPMs settle, release wheel brakes, push the throttle all the way to maximum, and guide the plane down the runway with gentle, gentle rudder inputs. If your twist rudder is giving you trouble, try simply using Z and X on your keyboard and see if that helps. If it does, then consider adjusting your twist rudder axis tuning.

Rotation is at I wanna say 340ish km/h, it can vary with load up to 370 km/h (maybe?) On rotate, pull up slowly but surely, with some authority, increase climb slowly maybe 10 or 20 degrees at full throttle. When the plane is positively climbing itself (which shouldn't take long at all), gear up, flaps up, and either level off or continue a more shallow climb to desired alt. Throttle down to 80-90% (or just follow the little Russian letter labels on throttle itself for a good cruise speed; middle one is fine) and pitch-trim the aircraft for your speed.

I'm not going in and getting the official numbers from the manual cause honestly, ballbark is good enough just to practice getting yourself in the air when it comes to the Su-25 series. I found it was far, far better to just practice, practice, practice for the "feel" rather than obsess over the numbers, when it came to my first experiences in the sim. Obsessing over the numbers is a fun part of the sim but your main goal right now should be reliably getting yourself off the runway.

The training mission is fine to learn the process, but frankly it's faster to use your own map (or generate mission with no planes from takeoff) once you know the process. No audio queues, no dialog, not "hit space bar to continue," etc. When you get up (or mess up) simply hit Left Shift+R to restart the mission and go again immediately. You can get the most reps this way.

Once you learn this takeoff procedure, it's the same for basically all the FC3 planes and the principles of takeoff will even help you with other modules. The only variables that change are speeds, how much rudder, when to rotate, angle to climb, etc.

Good luck and happy flying.

Honestly if the Su-25T is too clunky for you (it is a pig tbh) just try the F-15C. Don't have to worry about trimming the aircraft at all, really. The CAS and flight computer stuff is flying for you. The plane flies itself off the runway. At 150 knots you just pull back and as long as you don't exceed AOA limit too quickly you will get off the ground without scraping your butt. I've found that even if you do scrape the tail on the runway, the plane will often times be completely flyable, no major damage. You still have to worry about simple rudder for crosswind factors et al, but you're getting up to high speed so much faster there's less time you have to do it and keer 'er steady. You're off the ground so fast. You can climb the damn thing like a rocket ship if you want at full burner, literally like 40 degree then down to 25 degree climb no problem, up to 10,000 feet. Landing's not as easy as in the Su-25T though imho, because it can be harder to get from that high speed down to the speed you need, and the F-15 has no drogue chute to help you stop. Still, nothing crazy. Point the nose down at 5-10 degrees depending on distance as you set up approach. Pull the plane up as you come into your glide slope at 3 degrees (so about half way between level and down 5. Keep your speed 200 or less as you touch down on your back wheels, don't let AOA exceed 22. Drop the nose down and begin braking. Voila.
