STEFLY Canopy Flasher - Design and Function

SteFly Canopy Flasher Manual Version 1.2 5
• All required cables (12 VDC power supply to on-off switch / on-off switch to control box /
control box to canopy flasher)
• Masking foil template for precise alignment of the canopy flasher in the direction of flight
• Yaw string with clear adhesive pad and alignment template
3.2 Design and Function
SteFly canopy flasher was specially designed as visual awareness light for gliders and sailplanes. LEDs
are emitting green flashes with high luminous power. The light beam is formed by a reflector and the
housing, which is coated by a mirror foil.
The system architecture is shown below.
The canopy flasher is connected to the Control Box, which evaluates FLARM signals of aircraft in the
surrounding area. For safety reasons (dazzling) and energy saving, the canopy flasher only emits light
flashes, when the aircraft is flying. Therefore, FLARM is connected to the Control Box via a RJ45
cable.
An on/off switch has to be installed, to activate and deactivate the visual awareness light. It has an
integrated fuse against system overloads and system shorts. This switch is electrically positioned
between the storage battery(ies) and the Control Box. The switch must be accessible during the
operation of the aircraft and should therefore be installed in the instrument panel.
In case of jettison of the canopy for emergency exit, the design provides a quick separation
connector (standard) or a canopy contact (useful for side opening canopies, available as accessory).
