The ABV position is used to display traffic within which vertical range relative to your altitude?

• A. 9,900 ft above and 2,700 ft below
• B. 9,900 ft above and 3,000 ft below
• C. 9,900 ft above and 1,650 ft below
• D. 9,900 ft above and 9,900 ft below

Answer: (A)

ABV sets how far you see traffic on the navigation display relative to your own altitude. The standard window is 9,900 ft above and 2,700 ft below your altitude, meaning traffic up to about 9,900 ft higher or 2,700 ft lower will be shown. This asymmetric range is chosen to give you early awareness of traffic that could intersect as you climb or level off, while keeping the display manageable by limiting lower-traffic clutter. Other ranges would either clutter the display with unlikely threats or risk missing closer-in traffic, so this 9,900 ft above / 2,700 ft below window is the best balance for the ABV display.
