Fly-by

Waypoints and VOR stations can be used to define tracks or paths in air navigation. Such tracks can be airways, the segments of an approach procedure, etc.

If you are flying an aicraft equippd with an FMS (flight management system) it will tell you what anticipations are required in order to fly-by such waypoints or VOR/DME stations. If not ... well it is up to you, as an aviator, to work it out.

In still air, the fly-by manoeuvre depends on the inbound and outbound courses, the speed, the angle of bank and the rate of bank (rol-in and roll-out). In case of VOR/DME stations one also needs to know the height above such stations since the measured distance (DME) is a slant range!

The mobile application allows you to determine these anticipations. Have fun!
