Question

To set the high intensity runway lights on medium intensity, the pilot should click the microphone seven times, and then click it ________.

1) once
2) twice
3) thrice
4) four times

Answer 1

The pilot uses the Pilot-Controlled Lighting (PCL) system to control runway light intensity by clicking the microphone button a specific number of times; five clicks are required to set medium intensity after initially clicking seven times for high intensity runway lights.

Step-by-step explanation:

To set the high intensity runway lights on medium intensity, the pilot should click the microphone seven times, and then click it five times. In most controlled airports, the Pilot-Controlled Lighting (PCL) system allows the pilot to adjust the intensity of the runway lights by keying the microphone button on a specific frequency. One to three mic clicks sets the lights on low, five to seven mic clicks for medium intensity, and seven or more clicks within five seconds for high intensity. It's essential for the pilot to know this procedure to ensure the proper visibility during landing and takeoff operations.
