Here's is a version that I have customized for my own personal use, it allows me to input the Headwind or Tailwind correction and the Runway Limited Weight from the TPS and calculate the corrected Runway Limited Weight based on the current winds. I've also included the wind limitations for the MD-80 for quick reference. When you tap on the "HDWND or TLWND / KT" or "RWY LIM WT from TPS" fields, the same button bar that's used for inputting the wind direction and speed appears. Use this as the means to input the values rather than using the graffiti pad. Enter the "RWY LIM WT" as 4 consecutive numbers. The decimal place will be added automatically. THIS VERSION IS NOT OFFICIALLY SANCTIONED BY AMERICAN AIRLINES. I ASSUME NO RESPONSIBILITY FOR THE MISUSE OF THIS PROGRAM. PLEASE VERIFY THE ACCURACY OF YOUR RESULTS BEFORE MAKING A GO/NO-GO DECISION.
