Hey folks! Just created an IF calculator for randomized payloads, PLUS a quasi-E6B (somewhat limited) that computes various time-distance-fuel required/used-speed equations. There is also a searchable, sortable reference sheet tab for most of the aircrafts I used at the time I made the prototype of the app, that includes empty weight and passenger capacity. It is accessible here, although you will have to download “Open as App” from the AppStore to access it! Since I only have a basic account, it has to be run in the parent program’s shell. I could potentially get this app branded under my own name for the cost of a pretty penny per month!
Let me know what you think if you try it. Let me know what else I could integrate!
