NGX Brakes

Featured Replies

Dinshaw-So I guess what you are asking is: "PMDG: Have you modeled a truly inertia based autobrake for the NGX that works to accurately modulate brake pressure so that the airplane maintains a target rate of deceleration regardless of runway surface, braking conditions and/or the use of spoilers and/or reverse thrust? AND have you modeled the effects of converting the airplane's velocity changes as related to current aircraft mass during braking efforts while taxiing, RTO and on landing in order to realistically transfer energy to the brakes, while simultaneously accounting for the dissimilar energy distribution that would result from a failed brake or brakes? AND have you also accounted for radiative heating effects that accurately take into account the ability of static or moving air (Resulting from the airplane being stationary or in flight) to increase or decrease the radiation cooling effects of the brake assemblies? AND have you figured out how to allow us interested users to select between steel or carbon brakes on the airframes that offer the option? AND will there be difference in hot brake performance between steel and carbon brakes, AND have you developed an energy transfer model that will cause penalties for me as a pilot if I take off with superheated brakes and retract the gear into the gear wells?"If that is what you are asking, Dinshaw: Yeah... I got you covered on all of that. :(
:(If I could make this clapping little guy over here bigger I would...........well in theory, at least he can clap infinitely.

I assume your model takes into account air temp, humidity and density otherwise there's no reason to talk about realism here! :( Amazing Robert! It's all Greek to me and guess what... I'm from Greece! Big%20Grin.gif

I hate gravity!

I find it amazing how far people they have come in just the past few years. Everything RSR is saying I know in my heart has been modeled, because look at the 744, if you use the brakes too much they overheat. It blew me away the first time I got that warning message!! This plane is by far going to be up and over anything we have ever seen in the FS world to date!! With that being said I just have one more thing to say. THANK YOU PMDG!!!Big%20Grin.gif

Wait, what ? Seems like I'll need a break College degree so I can learn how to use the breaks!! :(

How can I takeoff with superheated breaks??And btw I would like to see different braking decelerations in dry, rainy, snowy, icy conditions. Best regardsKai Bock

Pushing back with the parking brake on would do the trick. Always heated up the brakes on the PMDG 747.What exactly would happen? Would it melt the tires or the legs of the gear? I could only imagine damage by overheating the gear bay.

Take-offs are optional, landings are mandatory.
The only time you have too much fuel is when you're on fire.
To make a small fortune in aviation you must start with a large fortune.

There's nothing less important than the runway behind you and the altitude above you.
It's better to be on the ground wishing you were in the air, than in the air wishing you were on the ground.

I just don't know where to start with the brakes: carbon or steel.........:(

My I politely suggest you read some of the posts above yours. You will find your questions have already been answered.

Brake degradation aside, what I would find revolutionary as far as FS is concerned is the ability to taxi on idle thrust. It seems to me like someone in Aces Studios in Microsoft left their finger on the friction button. The fact that I can idle out my small 1,200 lb Cessna 172, with a 5 knot tailwind, while going 20 knots, and still come to a stop in 200 ft says so much about Flight Sims faulty taxi mechanics.I don't even want to know how messed up the taxi mechanics are in Airliner sims for FS. I think I remember needing 60% N1 just to sustain a constant-speed taxi on the default birds. Yikes.
There is a way to change the coefficient of friction by updating a particular .DLL. This might have been for FS2004 only, but I'm kinda foggy on the details. Does anyone recall this?
