OVFY Δ Key

When pushed, Δ appears in the scratchpad. Line selecting the waypoint to be overflown causes the Δ to appear next to that waypoint designator in the flight plan, and the lateral flight plan is modified so that the airplane directly overflies the waypoint. The overfly function provides for flight directly over a waypoint while maintaining NAV. Once a waypoint has been commanded to be overflown, OVFY Δ can only be removed by reentering the waypoint name.
