cmbaviator Posted July 22, 2022 Share Posted July 22, 2022 Hell guys, I was wondering how to perform an aerodynalic breaking with the F1 because as soon as the main wheel touches down, the nose to th F1 severly goes down ? thanks 1 Link to comment Share on other sites More sharing options...
Lace Posted July 22, 2022 Share Posted July 22, 2022 I imagine you don't. You want to get all three wheels down sharpish so you can start slowing with the braking 'chute. Of course, if your SOP says no 'chute, then aerobraking will make more sense. Laptop Pilot.

SlipHavoc Posted July 22, 2022 Share Posted July 22, 2022 Page 108 of the manual says: After touchdown: i ̴ 13°. It is advantageous to use aerodynamic braking by holding the nose high down to 120 kts. I haven't landed it all that many times yet, but I haven't had much trouble holding the nose high after touchdown, although it does seem to want to touch the nose gear initially. I've found that retracting the flaps keeps it from wanting to take off again, but that may just mean I'm landing too fast. I do agree that the drag chute is the way to go though, the brakes aren't terrible but they're not great either, and even with aerobraking it can be a long runout on landing. But the drag chute works great. 4 Link to comment Share on other sites More sharing options...

Granted it was by accident and I haven't been able to do it again since, but I did do an aerobraking maneuver. I believe I was going in around 130kts.

RhineHornet Posted July 30, 2022 Share Posted July 30, 2022 It works! I just did it last night, nose gear did not go down on touch down, kept the nose up until about 110 knots. Love this jet... 1 [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...

jaguara5 Posted July 31, 2022 Share Posted July 31, 2022 (edited) The key to prevent the nose to come down and perform a correct aerodynamic braking is to be in the correct position at touchdown. According to the pattern diagram at short final you keep rpm above 7000 / i 10 deg speed / ~ 150 kts (typical landing weight 8700kg / 1000lt fuel remaining). Just before the touchdown you flare the ac by bringing the nose up so that you have the I at 13 degr and after the main gear comes on the runway you throttle back to idle. This stick aft input raises the nose so that the runway in front of you is almost not visible ( you have to raise also the seat and lean forward for better visibility). As a result the ac is already in a perfect position to perform the aero braking , slight aft input on the stick is then required to maintain that position. If you don' t raise the nose sufficient just before the touchdown or if you are to slow the nose landing gear will come come down quickly.

jojyrocks Posted September 12, 2022 Share Posted September 12, 2022 It can be done, you need to be in the AOA between green and yellow, or even just yellow and modulate the stick...Yellow has more chance of getting a good hold to aerobrake.

This is something I've noticed to some degree or another in every DCS module, ED or 3rd party, perhaps excluding the F-15C and F-16C, though the latter still wants to drop a bit on touchdown. It just takes practice to catch the nose and modulate the stick to keep it there without overrotating. 1 Link to comment Share on other sites More sharing options...

If you land hard enough a moment will push the nose down. It's all about landing gently, though that doesn't mean that the suspension model might be off on some modules. 2 Awaiting: DCS F-15C Win 10 i5-9600KF 4.6 GHz 64 GB RAM RTX2080Ti 11GB -- Win 7 64 i5-6600K 3.6 GHz 32 GB RAM GTX970 4GB -- A-10C, F-5E, Su-27, F-15C, F-14B, F-16C missions in User Files Link to comment Share on other sites More sharing options...

Or the rubber/pavement physics model. I remember a lot of debate regarding the warbirds on that, and certain modules seem heavier or lighter than they reportedly should be in terms of required thrust for taxi, etc. 1 Link to comment Share on other sites More sharing options...

So far, when it comes to Difficulty on aerobraking for DCS planes: This plane is doable, when you get it to angle on Yellow on AoA, easier to hold the aerobrake nose up. It is easier when lightly loaded. If loaded, can be bit hard. The impossible model in DCS is F-18, unless you put flaps to half, you just cannot aerobrake (I've seen Finnish pilots do it). The second most hardest is Mig 21 and 3rd, the Tomcat. Link to comment Share on other sites More sharing options...
Baltic Pirate Posted September 13, 2022 Share Posted September 13, 2022 Seems to work fine. However the combination of aerodynamic braking and drag chute is a tid bit harder as the nose comes down with the deployment. Link to comment Share on other sites More sharing options...

I've never had trouble with landing tricycle planes in any sim, and DCS is no different. If you are having problems landing planes in DCS World, 99% it's on the pilot and not the flight model.

When you slam the center of gravity into the ground, its inertia will rotate the jet around the MLG and slam the nose wheel into the ground. I'm not saying that it is easy - certainly not for me. 1 "Muß ich denn jedes Mal, wenn ich sauge oder saugblase den Schlauchstecker in die Schlauchnut schieben?"

The issue is not landing correctly but maintaining the AoA on touch down, on the mirage F1 or F18, as soon as you down down and even with a kiss lànding, the nose wheel steering slams the runway big time 2 Link to comment Share on other sites More sharing options...
Giskvoosk Posted September 14, 2022 Share Posted September 14, 2022 Have been shamefully slamming on touchdown since day 1, here's my first attempt in a more gentle manner. There's a dip but feels totally manageable. https://imgur.com/HJOPYdD IRL aerobraking from hud cam view: 1 Link to comment Share on other sites More sharing options...

And its doable for sure i did one in the first run, check the imgur link above. The key point as others have already suggested is to control your vertical speed before touchdown.
