OS & J_T
If I may add a plug for a company in Colorado that does runway analysis for operators based on FAA AC 120-91, Runway Analysis. My employer subscribes, it is Ops Manual requirement to use them. I have found them very good, once each pilot has received training on the problem and the analysis. In the spirit of the thread, the company is A.P.G.; also available if one subscribes to brand AR Incorporated flight planning.
