A single weatherproof unit houses 2 single colour projectors, synchronised to produce 3 indications which are visible to approaching aircraft : HIGH, CORRECT and LOW signals relative to the chosen glide slope.

Detachable weather protection shroud keeps sight glass clear of contamination.
The indication
protocol is factory set and uses combinations of RED and WHITE signals.
This is simple and easy to follow with clear un-ambiguous transitions. The signal appears a single bright
light. Intensity can be altered and selected via a 3 position switch.
The angle of the
beam is adjusted electrically & controlled by a switch. The angle is
indicated by an LED display. The range of adjustment is from 3 deg. to
16 deg. in 0.1 degree increments. 2 sensors detect and measure the
angle of :
a) the projector assembly & beam angle
b) the complete assembly relative to 0 deg. This is a 'tilt' system that
disables the unit if the level
is disturbed. Minor vibration or temporary movements do not deactivate
the system.
No calibration or maintenance is required except for scheduled checks
and the unit contains no user serviceable parts. Lamps have a service
life of over 40000 hours. An on-board heater and drier prevents misting
on the lens surface. Long term storage in normal indoor conditions will
have no adverse effects. All bearings are lubricant free. The sight
glass does not require special treatment & can be cleaned with water and
a clean cloth.
The unit can be switched on in 'standby' mode, which operates the lens demisting heater and turns on the level circuits.
Power consumption is only one quarter of full lighting mode. When the lamps are switched on they activate immediately.
The GL3 is a battery powered portable approach path indicator, designed for rapid field deployment from improvised landing sites. Minimal training is required for setup and the unit is ideal for Home Defence and Disaster Management.
...............Night brightness and accuracy is comparable to fixed airport systems such as PAPI or APAPI
The
device is housed in a 6mm. thick aluminium case which is sealed
for life and is capable of accepting very rough treatment. The
lens aperture is thoroughly shielded to prevent physical damage
and prevents rain, snow or mist from settling on the glass. The
operating switches are fully recessed and protected from damage.
Water/dust proofing is to IP67.
Although rugged, the GL3
is a precision instrument that does not compromise portability
for accuracy.
The beam angle is instantly adjustable
The lighting head, along with its accessories, is compact & strong enough to fit in a shoulder bag but is normally packed in small Peli-Case . see KIT OPTIONS
