ATC AP Characteristics Practice Test

Which description best matches ILS hold position markings?

Two Dashed Lines On The Runway Side Two Solid Lines Spaced 2 Feet Apart Connected By Pairs Of Solid Lines Spaced 10 Feet Apart, Without Any Signage Two Solid Lines Spaced 2 Feet Apart Connected By Pairs Of Solid Lines Spaced 10 Feet Apart, With A Mandatory Sign Reading ILS Adjacent A Yellow X At The Hold Point

Correct Answer:

Two Solid Lines Spaced 2 Feet Apart Connected By Pairs Of Solid Lines Spaced 10 Feet Apart, With A Mandatory Sign Reading ILS Adjacent

Explanation:

ILS hold position markings mark the boundary where aircraft must stop to protect the instrument landing system’s critical area during an approach. The correct description includes the distinctive line pattern of two solid lines spaced 2 feet apart, connected by pairs of solid lines spaced 10 feet apart, and it is paired with a mandatory sign reading ILS adjacent. That sign tells pilots this hold point is specifically guarding the ILS critical/approach area, so crossing only occurs with explicit clearance. The other options either omit the required ILS signage, depict a different marking, or show a symbol used for a runway closure, which isn’t what the ILS hold uses.
