6.4.5 Above Field Callout
A “500 ABOVE” or “500” callout is provided when the aircraft is within 5 nm’s of a runway and the aircraft is configured for
the above field callout.
Geometric altitude and the runway database are used to calculate the height above field and the 500 Above Field Callout is
initiated when descending below 550 feet.
Once this condition occurs a power save NVM lockout latch will be set to drive the message request latch. Once set, this
lockout latch will inhibit the 500 Above Field Callout from being requested again until a Height Above Runway Field is
greater than 700 feet (the next approach or go around). A transition detection on the output state of this latch will drive the
voice message request latch.
