Hi Team-This feautre would be great for me and I wondered if it would be possible?Could you make it so when landing in the rain the brakes are not as effective? For example, if you select auto brake 2 the instruments show the appropriate amount of hydraulic pressure for auto brake 2 however it "secretly" only applies say auto brake one pressure and so simulates a wet runway and reduced braking effectiveness. Or is this too extreme?Regards,PaulP.S. Expect more ideas soon ;-)

The idea is good, just not for autobraking ;-)An autobrake preset doesn't apply a constant brake pressure, instead it aims for a constant deceleration rate. Thus, landing on rainy or on a dry runway with autobrakes "2" won't result in a landing roll difference (except if the runway is too wet, and the friction available isn't enough for the preset deceleration rate...)Regards,Mark

Indeed, autobrakes aim to stop you in a set distance and adjust braking force accordingly (or so i read)Liam(edit added name)

I didn't know that. Anybody got any tables?

Not quite.Again, autobrakes aim for a preset deceleration rate. The stopping distance depends on your groundspeed at touchdown. (So, if your groundspeed would be constant, then yes, your distance would be the same as long as the friction between the wheels and the runway is sufficient)Regards,Mark

What's the rate of deceleration using autobrake1, autbrake2 etc in metres per second per second. Anyone know? I bet some NG Captains out there know. ;-)Paul

Ah you are right..I think i mis read something in the past or perhaps its different on different aircraftLiam
