Autobrake Landing Distance Calculation

Autobrake Landing Distance Calculation

In order to calculate the Landing Distance with the different Autobrake settings, use the following formula:

💡

Autobrake LOW = Grossweight (GW) in tons x 30

Example:

GW 60 tons = 60 x 30 = 1800 Meters required Landing Distance

💡

Autobrake Medium= Grossweight (GW) in tons x 20

Example:

GW 60 tons = 60 x 20 = 1200 Meters required Landing Distance

💡

In case the runway is wet, add another 15% to that.

I.e. Required Landing Distance = 1200 + 15% (180 m) = 1380 Meters
