Airspeed Indicator Markings

The airspeed indicators in the club gliders have been marked with critical speeds. This was done with simple colored tape on the instrument glass rather than trying to open the ASIs in order to do colored arcs. The colors and indicated speeds are given below. Note that these speeds are from the POH for each glider and are approximate.
    White     Stall
    Blue     Minimum Sink
    Green     Best L/D
    Yellow     Maneuvering
    Red     VNE
