Definition
A four-pointed cross marking shown on an instrument approach chart's profile view to identify the precise point where a non-precision approach procedure transitions from the intermediate segment to the final approach segment. It marks the Final Approach Fix (FAF) and indicates where the pilot begins the final descent toward the runway.
Plain English
A small cross-shaped symbol on the approach chart that shows exactly where you start the final descent to the runway on a non-precision approach.
Context Anchor
Seen in the profile view of instrument approach charts, especially on nonprecision approaches.
Derivation
Named after the cross used by the Knights of Malta — a four-pointed cross with V-shaped arms. The shape was adopted as a chart symbol because it is visually distinct and easy to spot on a busy approach plate.
Why Pilots Care
It tells the pilot the exact point at which descent to the next published altitude may begin and the final approach course must be tracked.
Grounding Statement
When you see the Maltese cross in the profile view, think: this is the marked start of the final approach segment for this nonprecision approach.
Intuition Check
Do not treat the Maltese cross as decoration or a general warning mark. On an approach chart, it has a specific meaning: it marks the final approach fix for a nonprecision approach.
Example Sentence 1
Crossing the Maltese cross, the pilot started the timer and began the final descent to the minimum descent altitude.
Example Sentence 2
In the profile view the Maltese cross symbol appears several miles from the runway to mark the start of the landing segment.
