What is the approximate landing ground roll distance at a pressure altitude of 1,250 ft with a headwind of 8 kts?

The landing ground roll distance is influenced by several factors, including pressure altitude and wind conditions. At a pressure altitude of 1,250 feet, the air density is somewhat lower than at sea level, which can affect the aircraft's performance during landing. However, the presence of a headwind, such as the 8-knot headwind mentioned, plays a significant role in reducing the landing ground roll distance.

When an aircraft lands into a headwind, it is effectively reducing the ground speed at which it contacts the runway. This lower ground speed results in a decreased landing roll distance because the aircraft has less kinetic energy to dissipate upon landing. Therefore, the contribution of the headwind to the landing performance is significant.

The choice indicating 366 feet accurately reflects the combination of the pressure altitude and the effectiveness of the 8-knot headwind. It balances the performance adjustments that need to be made for landing at a moderate altitude while considering the benefits of the headwind.

In this scenario, the combination of the pressure altitude and a headwind allows for a safer and shorter landing roll, as opposed to landing without wind assistance or with a tailwind, which would increase the ground roll distance.
