The principal requirement for a signals area on an aerodrome is that it must be clearly visible from which location?

• 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)

What matters is that ground signals are visible to pilots wherever they are on the manoeuvring area. The signals area needs to be clearly seen from all parts of the manoeuvring area so that aircraft taxiing in any location can receive and interpret the instructions without needing to reposition themselves to see the signal. This ensures safe and unambiguous ground movement.

The other points aren’t the primary concern: being visible from the air isn’t required because these signals guide ground taxiing, not flight operations; the area doesn’t have to be large enough to contain every signal, as long as the signals are visible from everywhere on the manoeuvring area; and the use for VFR or IFR operations doesn’t determine the visibility standard.
