Final answer:
The point near the runway end for touchdown RVR and winds helps pilots obtain visibility and wind condition information for landing. It requires calculating the right approach angle accounting for runway direction, wind, and plane's speed. Pilots must be ready for last minute maneuvers for wheel alignment.
Step-by-step explanation:
The purpose of a point near the approach end of a runway for touchdown runway visual range (RVR) and winds is to provide pilots with critical information regarding the minimum visibility required for landing, as well as the wind conditions that affect the final approach and landing phases. In a scenario with crosswinds, pilots must calculate the correct approach angle to maintain a velocity parallel to the runway. This requires considering the direction of the runway, the wind speed and direction, and the airplane's speed relative to the air mass. After making these calculations, a pilot must still be prepared to perform last minute maneuvers, such as adjusting the yaw of the aircraft, to ensure the wheels are aligned correctly for a safe touchdown.
