Primary Flight Display Symbols
Vertical Deviation Indication
On GPS-equipped airplanes, the vertical deviation indication, scale, and index appear magenta when:
- A non-precision approach (VOR, ADF, RNAV, or GPS) has been selected, and
- The PERF APP phase is active.
The Vertical Deviation Indication flashes amber if the ILS/LS button is selected ON when the APP NAV mode is armed.
