Henning Dammann-Emden asked what "shoot an approach" means and John Smith
answered, "Possible origin is the Instrument Landing System. When flown
correctly the vertical and horizontal guidance indicators are centered in
the face of the display. These crossed indicators have the appearance of the
crosshairs of a telescopic sight. Hence, you shoot the approach. Keeping the
crosshairs centered generally assures that you will hit what you are aiming
for... the runway."

Good explanation, John! I've heard the expression for years and always
wondered about its origin, but never thought to ask.

Thanks,

Jon
