Stabilised Glide Slope Indicator (SGSI)
The stabilised glide slope indicator is used on moving landing platforms such as aircraft carriers. The SGSI projects a beam of light, with coloured sectors, from the aft face of the ship. This beam is stabilised to remove the effects of the ship's roll and pitch and provides the pilot with visual information relating to the approach angle. The coloured sector of the beam indicates if the aircraft is above, below or on the correct glide path. There are various beam configurations available to suit different naval requirements.
Famous quotes containing the word glide:
“Our life is not so much threatened as our perception. Ghostlike we glide through nature, and should not know our place again.”
—Ralph Waldo Emerson (18031882)
