This is the second segment of a two-segment post. Mathematical calculations can be used to determine Vref and Vapp based on wind speed, direction, and gusts. Failure to do this may result in the aircraft landing at an non-optimal speed causing runway overshoot, stall, or floating ( ground affect).

When landing with a headwind, crosswind, or tailwind the Vref and Vapp must be adjusted accordingly to obtain the optimal speed at the time of touchdown. LEFT: Final Approach: Finals using 'crab approach' (Airbus A320) Vref is defined as landing speed or the threshold crossing speed, while Vapp is defined as the approach speed with wind/gust additives.

The purpose of FLAPS-2-APPROACH is two-fold: To document the construction of a Boeing 737 flight simulator, and to act as a platform to share aviation-related articles pertaining to the Boeing 737 thereby, providing a source of inspiration and reference to like-minded individuals.
