Report: Approach Hold Short Lines Confuse Flight Crew

A flight crew departing Madison, Wisconsin (KMSN) reported confusion during taxi about approach hold-short markings for Runway 14. Here's what happened...

But was this necessary? Here's what you need to know...

Approach Area Markings

At some airports, approach hold areas are designated to prevent taxiing aircraft from conflicting with those landing on nearby runways. You'll find them in areas where taxiways lie underneath or directly adjacent to a final approach path. A red sign with a white designation of the approach end of the runway followed by a "dash" (-) and letters "APCH" will be located at the holding position on the taxiway.

Identical to runway hold-short markings with two solid yellow lines and two dashed yellow lines, approach holding position markings will be located on the taxiway pavement too.

Hold-Short Of Approach Areas When Instructed

According to the FAA's AIM 2-3-5, "when specifically instructed by ATC, 'Hold short of Runway XX approach or Runway XX departure area,' the pilot MUST STOP so that no part of the aircraft extends beyond the holding position marking."

If you are not given this specific instruction, you're NOT obligated to hold short of the approach area. However, just like pilots, ATC can make mistakes too. If you notice that the runway corresponding to the approach area is in use, you should clarify that you are cleared across.

Because they're not always right next to a runway, you'll find approach hold-short markings in some unexpected spots along taxiways. That's part of the reason why they can be confusing or startling to pilots, especially at night.
