MacCready Setting

On the Nav page, choose the Speed button.

The bottom speed given on the right (65.3 Knots in the photo) is the "speed to fly". Press on this speed to open the settings page.

MacCready Setting
Choose the MacCready (MC) setting you wish with the buttons (0-5) on the Nav page, or on the slider of the settings page, which is opened by pressing on the "speed to fly" speed (101 in the photo at the right. Choose the MacCready (MC) setting you wish, which if you're trying to push hard to get the fastest flight, would be the average thermal vertical velocity you expect. The speed to fly will increase as you increase this setting, and will also change with the wind settings.

Flying at a MC setting of 0.00 is a conservative way to fly, which keeps you close to best glide.

The app does not yet implement a dynamic speed to fly. In other words, it does not tell you to fly faster in sinking air.

Arrival Altitude
Choose a safe height above your waypoint for landing, or for other clearance you may need, for example over a mountain ridge. This setting is saved and loads each time you restart the app.
