When can IAFDOF color coding be deleted?

• A. After coordination is accomplished or the LOA altitude overrides the IAFDOF.
• B. Immediately after crossing boundary.
• C. Only when LOA demands even altitudes.
• D. Never.

Answer: (A)

IAFDOF color coding is a temporary display used during coordination to show which initial approach fix and related altitude constraints are active. It should be deleted once coordination is accomplished or when an LOA altitude override makes the IAFDOF no longer the controlling reference. This keeps the display accurate and prevents confusion as the clearance context changes. It isn’t removed immediately after crossing a boundary, since the coordination and clearance status may still be evolving. It isn’t limited to cases where the LOA demands even altitudes alone, and it isn’t never—there are explicit conditions under which the coding is removed.
