The new update was approved yesterday. I have an update to the update almost ready to submit. This adds a couple nice features to the altitude prediction calculator. It will show the percentage motor class and the thrust to weight ratio. The thrust to weight ratio will display green if above 5, and red if below. If below 5, it will warn the user. It will also alert the user of possible inaccurate results if the flight is transonic. This calculator uses a static drag coefficient, but in a transonic flight the Cd will increase rapidly at Mach 1. The enabling/disabling of alerts will be manageable from the app settings. These features should be available sometime next week.
