What is the required additional feet of landing ground roll for heavy weight flaps?

When considering the effects of landing with heavy weight flaps, it's crucial to understand that the aircraft's configuration significantly influences its landing performance. Heavy weight flaps reduce the stall speed and increase lift, but they also introduce more drag, which can lead to an extended landing roll.

In this context, the appropriate landing ground roll for heavy weight flaps is an additional 500 feet. This figure is derived from data that demonstrates how much longer it takes to decelerate and come to a complete stop when an aircraft is configured with flaps in a heavy state, as the aerodynamic characteristics of the aircraft change.

This extended landing ground roll is essential for pilots and flight planners to consider, as it affects runway length requirements and approach management. For instance, knowing this metric helps in safely planning landings, particularly at airports where runway length may be a limiting factor. Overall, using the additional 500 feet as a reference ensures safe operation under different weight and flap configurations.
