After looking at the map my airspeed drops alot?

From FlightSim

Q:

Every time i return to cockpit view after looking at the map, my airspeed drops by a considerable amount. Has anyone else had this problem, and know of a solution?

A:

The Map View is a tool to set your altitude, location and speed it was in the "Goto Exact location" in FS98. To avoid invoking this function, use the"X" button to return.
