iFly GPS Forum

I don't know if this is general or iOS specific.

Using simulator mode to familiarize myself with some features, I set up a flight to a nearby airport. At a point in the flight, I was alerted to begin my descent. The alert fired based on a target descent rate of 620 FPM. is that 620 a fixed value or can I change it? I looked around the app and couldn't find a setting for it.

Climb rate and descent rate are user inputs on the Aircraft Profile screen that you set up.  It can be different for each aircraft.  Tap Menu/Setup/Edit Aircraft.  If you have the VST (Vertical Speed to Target) instrument on screen, it will light up before you reach the desired vertical speed, and you will get the popup alert when the desired climb/descent rate is reached.

I don't use the simulator so I'm not sure how it works.  I would think it works exactly as if really airborne, but it might can get confused by immediate changes in the aircraft's location and altitude, as in resetting a location to fly an approach, etc.
