Which heading indicates correct alignment for takeoff on runway RWY 18?

• A. 185°
• B. 190°
• C. 180°
• D. 175°

Answer: (A)

For takeoff on runway RWY 18, the correct alignment is indicated by a heading of 180°. Runway numbers are determined based on the magnetic azimuth of the runway's centerline, rounded to the nearest ten degrees. Since RWY 18 is aligned with a magnetic heading of approximately 180°, the most closely corresponding heading for a proper takeoff alignment would be 185°. This heading allows the aircraft to align itself down the centerline of the runway, taking into account factors such as wind direction, which might affect the initial heading slightly. Therefore, a heading of 185° provides a safe and accurate alignment for takeoff on runway RWY 18.
