Airplanes: Turbine engine powered: Landing limitations: Destination airports

This regulation sets weight and runway length limits for turbine-powered airplanes to ensure safe landings at destination airports.

First, the airplane's anticipated arrival weight (after burning fuel en route) cannot exceed the maximum landing weight in the Aircraft Flight Manual for the destination's elevation and expected temperature.

Second, for most operations, the airplane must be able to stop within 60% of the available runway length from a 50-foot height. Calculations assume landing on the most favorable runway in still air, but also consider the most suitable runway given expected winds and conditions.

Special provisions allow:

• Turboprops to use an alternate airport requiring only 70% of runway length if the destination doesn't meet the 60% rule
• Turbojets to use an alternate meeting the standard 60% requirement as an alternative to the destination
• Turbojets require 115% of the calculated runway length when runways are forecast wet or slippery, unless shorter distances are specifically approved
