FAA LIGHTNING PROTECTION STUDY: LIGHTNING PROTECTION REQUIREMENTS FOR AN/GRN-27(V) INSTRUMENT LANDING SYSTEM
The withstand capabilities and protection requirements for solid state circuits of the AN/GRN-27 (V) Instrument Landing System susceptible to lightning-induced transients on buried control cables are presented. Susceptible circuits and components were identified from the wiring diagrams as transistors, diodes, relay contacts, and electrolytic capacitors. Withstand capabilities of each circuit were determined analytically using manufacturer's data and a 1000-volt, 10 x 1000 microsec test waveform. Avalanche diode surge protectors and series resistance are recommended to protect susceptible circuits from lightning-induced transients on buried control cable conductors connected to the circuits.
