May 21, 20224 yr Just wondering why planning for reverse idle or max reverse seemingly has no impact on the landing distance calculations in the EFB? Edited May 21, 20224 yr by Andreas Stangenes Andreas Stangenes http://www.youtube.com/user/krsans78 Add me on gamertag: Bullhorns78

Because in real life with automatic braking selected and good braking conditions they also don’t, it’s mostly to reduce wear and tear on the brakes, the braking distance remains the same the brakes simply don’t apply as hard as they’d have to if the reversers weren’t used.

May 21, 20224 yr If you change the runway condition you'll see that it makes a difference on contaminated runways.

May 21, 20224 yr The autobrake setting is a deceleration target, not a fixed amount of brake pressure. If for example you set autobrake low and full reverse, on landing the aircraft might not apply ANY brakes, because the deceleration target is being met from the thrust reversers alone. It does not 'sum' the autobrake and reverse. Note that I don't have the Fenix EFB in front of me so it could be a bug, but you could experiment with contaminated runways and it should make a difference.

On contaminated runways MAX reversers give about 10% less landing distance, so that works too (in the calculations). For transparency: I'm a community mentor at the BATC discord. However, I do not get paid for it in any way.
