What is the principal requirement for a signals area on an aerodrome?

• A. It must be clearly visible from the air
• B. It must be clearly visible from all parts of the manoeuvring area
• C. It must be big enough to contain all signals
• D. It is used for VFR + IFR operations

Answer: (B)

Signals on the aerodrome must be readable from wherever an aircraft is operating on the ground. The main requirement is that the signals area be clearly visible from all parts of the manoeuvring area, so a pilot taxiing, waiting, or lining up can confidently see and respond to the signals. This ensures consistent guidance and reduces the risk of misinterpretation or wrong actions due to blind spots in sightlines. Visibility from the air or the area’s size isn’t the primary concern—the essential factor is that ground signals are visible to aircraft anywhere they may be on the manoeuvring area, regardless of the operating conditions or flight rules.
