Abstract

The present invention is directed to novel methods for depicting glide range on moving map displays and on perspective-view primary flight displays. These methods involve processing data gathered from various aircraft sensors and, using a variety of electronic databases, generating intuitive symbols that aid the pilot.

Claims

1. A moving map display for an electronic flight instrument system comprising:

a map depiction; and

a glide range depiction.

2. A primary flight display for an electronic flight instrument system comprising:

a horizon depiction; and

a glide range depiction.
