Yes. Performance calculations for the AFM provided surface conditions are available. Generally, these include actual distance for dry, wet, and contaminated runway surfaces, but this depends on each aircraft and its AFM.
Additionally, the landing performance view includes a Landing Factor input. This is a landing distance multiplier of 1.0 or greater. Depending on the operation type, a landing at the intended destination (and alternates) must be shown to be possible with forecasted weather conditions and the use of a landing factor, which increases the actual landing distance to provide a safety buffer. The landing factor use is designed to ensure a successful stop on a portion of the available landing distance (LDA).
Part 121 and 135 operators must show landing and stopping ability using the 60% distance factors, meaning the aircraft must be able to land and stop on 60% of the available LDA for predicted weather conditions at the time of arrival. For a predicted dry runway condition the AFM dry distance is factored (multiplied) by 1.67 to achieve the 60% Dry factored landing distance. This longer distance is compared to LDA. The process is identical for a wet runway condition, but the 60% Wet factor is now 1.92 times the dry AFM distance, which is 1.67 increased by 15%.
Part 91K and some approved 135 operators use 80% distance factors, which are 1.25 for dry and 1.44 for wet runway conditions.
The landing factor selector includes these four common factors, as well as the ability to set a custom factor.
NOTE: If your operations always use a landing distance factor, you can set its default for your aircraft in MORE > AIRCRAFT > YOUR AIRCRAFT > FIELD PERFORMANCE.
