Definition
Yellow arrow heads are pavement markings painted across the width of a runway just before a relocated threshold, indicating that the pavement behind them is not available for landing, takeoff, or taxi.
Plain English
They are yellow arrow tips painted on the runway surface to warn pilots that the section of pavement behind them cannot be used at all — no landing, no takeoff, no taxiing.
Context Anchor
Seen on a runway when the threshold has been temporarily moved, often because part of the runway is closed or not available for normal use.
Why Pilots Care
Landing short of the indicated threshold can place the aircraft on pavement that is closed or unsafe, risking runway excursions or structural damage.
Intuition Check
Do not read these as general direction arrows telling you where to turn. In this runway context, yellow arrow heads mark a relocated threshold and point attention to the new usable runway starting point.
Example Sentence 1
On approach, the pilot noted the yellow arrow heads and aimed for the relocated threshold further down the runway.
Example Sentence 2
During the pre-landing check, the crew confirmed the yellow arrow heads were visible and aimed touchdown beyond them.
