Simultaneous operations on parallel runways require the missed approach course to diverge immediately by what angle?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 60 degrees

Answer: (B)

Simultaneous operations on parallel runways require the missed approach course to diverge immediately by 30 degrees to ensure safe separation between aircraft. This divergence angle is crucial in preventing potential conflicts or collisions when two aircraft are missed approaches on parallel paths; the 30-degree angle helps maintain enough lateral separation during the critical phase immediately following takeoff or go-around.

Choosing an angle of 30 degrees is based on safety standards established to effectively manage the airspace, allowing for sufficient distance between aircraft to reduce the risk of wake turbulence, lest the two trajectories intersect. Additionally, this angle allows aircraft to safely transition into their respective flight paths without encroachment, thus promoting safer and more efficient operations in busy terminal airspace.
