Question 8

The reason why pre take-off holding areas are sometimes further from the active runway when ILS Category 2 and 3 landing procedures are in progress than during good weather operations is:

Accepted Answer

Aircraft manoeuvring near the runway may disturb guidance signals

Answer

Heavy precipitation may disturb guidance signals

Answer

To increase aircraft separation in very reduced visibility conditions

Answer

To increase distance from the runway during offset approach operations
