This app was created, to practice the calculations off the VAPP and the RLD or FOLD, for the following A320 models: A320-214 and 216 CFM, 232 IAE, 251N CFMI and the 271N PW.
The tables used for the calculation are, the ones found in the QRH, IN FLIGHT PERFORMANCE chapter, "VAPP DETERMINATION WITHOUT FAILURE". All the corrections including the "SPD" are calculated automatically (remind that any "PILOT VREF CORRECTION" will be added to the "SPD" correction).The FOLD calculation is achieved by adding xx% to the corrected landing distance.
