What does the black D symbol near the airport diagram on an instrument approach plate denote?

• A. Declared Distances
• B. Distance Measuring Equipment
• C. Degree of Approach Terrain
• D. Declined Airspace

Answer: (A)

That black D tells you declared distances are published for that airport. It flags that the takeoff and landing performance numbers you’d use—TORA, TODA, ASDA, and LDA—are not necessarily equal to the runway’s physical length because of displaced thresholds, stopways, or other obstacles. To get the exact values, look up the declared distances in the airport’s data in the Chart Supplement (A/FD) or the notes accompanying the approach plate. It isn’t indicating DME, terrain degree, or airspace.
