asl

For years I've been using an app for programmed flights, iOS It is still good but not updated for almost a year. I bought Litchi a couple of years ago but used it only for tests. I am planning to use it more frequently. One data info that is very useful for me is the ASL (above see level)...

I'll preface by saying... I'm NOT attempting to circumvent FAA recommendations so please don't chastise me for asking this question without seeing & understanding the context. I'm standing near the base of a +2,000-ft mountain and launching my P3P. I want to fly up the side of the mountain...
