Badger1-1 Posted October 1, 2023 Posted October 1, 2023 Hello all, just a short one but I wonder why nobody ever had the same issue. I feel like the brakes on many, if not all aircraft are very weak. Surely often times its a operator error but I tested for example the F15E on a 1500m Runway, upslope and with no external weapons, low on fuel, touchdown with about 170kts at the TDZ and i shot past the threshold with about 80kts to spare. With the F16 its the same(not limited to these two), the brakes in general feel rather weak. Almost a litte bit of slipping, even with Antiskid and no wind. And before everyone starts hating that I just have no Idea what Iam talking about. I guarantee you, I know you can land a 80000lbs Aircraft in less than that.(thats MTOW of course landing is much lower) anyone else also has the same feeling? for me its the friction of the tires thats not correctly modeled. Cheers Badger
Hiob Posted October 1, 2023 Posted October 1, 2023 That‘s funny. Because I would absolutely agree that braking needs an overhaul (which is mostly the fault of ground physics like the friction coefficient of the tarmac in my perception), the Aircrafts you mentioned are quite opposite on the spectrum. The Streagle brakes rather good. That is when you honor realistic landing weights. The Viper on the other hand really has weak brakes (which is realistic unfortunately). 2 "Muß ich denn jedes Mal, wenn ich sauge oder saugblase den Schlauchstecker in die Schlauchnut schieben?"
Badger1-1 Posted October 1, 2023 Author Posted October 1, 2023 I just did the same flight with a F14B, 60000lbs landing weight and it stopped after 600ish meters. Like it should. I guess its not EDs problem
Bremspropeller Posted October 1, 2023 Posted October 1, 2023 (edited) I also think the brakes are too weak, but then again military aircraft are prolly not adherent to the same RTO design-criteria (e.g. stopping at MTOW @V1 on brakes only). Now, you can tailor your V1 speed obviously, but you'll get ridiculously low numbers. What's more of an issue to me is that some aircraft are almost unflyable (TO / landing) with some medium degree of crosswind. Edited October 1, 2023 by Bremspropeller 2 So ein Feuerball, JUNGE!

That‘s what led me to believe that it is the friction on tarmac that is the root cause of the issue. But in the end we all agree that braking is an issue. 2 "Muß ich denn jedes Mal, wenn ich sauge oder saugblase den Schlauchstecker in die Schlauchnut schieben?"
