2-11. SIGNALING MIRROR, TYPE 1,
MARK 3 (Figures 1-3, 1-4, 1-5;
items 18. 12 and 15)
The signaling mirror is a glass signaling instrument equipped with a
retaining cord on one corner and a see-through sighting device in
the center of the glass. When used in daytime and with good
visibility, a mirror flash can be seen at a distance of 30 miles at an
altitude of 10,000 feet. Though less effective, and with possible
shorter range, mirror flashes can also be seen on cloudy days with
limited visibility. The mirror can also be used on bright moonlit
nights. Procedures for using the mirror are as follows:
a.
Hold the mirror in a manner which will allow the
sunlight to reflect on a nearby surface, such as the hand or other
close object.
b.
Bring the mirror up to eye level and using one eye, look
through the sighting device until an intense bright spot is located.
This is the aim indicator.
