NOTES: 1. EXAMPLES ABOVE ARE ILLUSTRATIONS OF THREE WAYS TO CIRCUIT RUNWAY EDGE LIGHTING.
2. INBOARD IN-PAVEMENT THRESHOLD LIGHTS SHOULD ALTERNATE BETWEEN APPROACH LIGHT
CIRCUIT AND RUNWAY EDGE LIGHT CIRCUIT(S).
3. TYPES OF SIGNS THAT MAY BE CONNECTED TO RUNWAY EDGE LIGHTING: RUNWAY EXIT SIGNS,
MANDATORY HOLD SIGNS, MARKERS. OTHER SIGNS SHOULD BE CONNECTED TO TAXIWAY CIRCUITS.
4. DO NOT ALLOW MORE THAN ONE PRIMARY CIRCUIT TO BE INSTALLED IN ANY ONE CAN OR LIGHT
BASE. USE CANS TO ISOLATE PRIMARY CIRCUITS.
15-5.1.2
Saturable Reactor (liquid type, where degree of reactor saturation via
closed control loop determines output current).
