Which hold position is designed to hold short of the ILS approach critical area?

• A. ILS Critical Area Hold Position
• B. Runway Approach Hold Position
• C. Runway/Runway Hold Position
• D. Taxiway/Runway Hold Position

Answer: (A)

Protecting ILS navigation signals during approach is what this question is about. The ILS critical area is a protected zone around the approach equipment where interference could degrade the localizer and glideslope signals. To prevent any traffic from entering that space when needed, there is a specific hold point that stops aircraft and vehicles short of the boundary, ensuring the protected area remains clear until clearance is given. The hold position designed to hold short of the ILS critical area is the ILS Critical Area Hold Position. It provides a clearly marked boundary and instructs pilots to stop before entering the protected space, preserving signal integrity for approaching aircraft. Other hold positions exist for different runway and taxiway scenarios—such as preventing entry onto a runway or at runway intersections—but they are not specifically aimed at protecting ILS signals.
