How many radials should aircraft avoid in climbs or descents from the marshal radial on the holding side?

Aircraft should avoid 30 radials in climbs or descents from the marshal radial on the holding side to ensure safe vertical separation and lateral distance from other traffic. This practice is crucial for maintaining safe operations as aircraft maneuver through controlled airspace, particularly during the critical phases of climb and descent.

When discussing the rationale behind this specific number, it’s essential to note that the 30 radial avoidance ensures that aircraft are sufficiently distanced from other traffic that may be operating within the same airspace. By implementing this standard, air traffic controllers can effectively manage congestion and avoid potential conflicts, especially near busy airports or during high-density traffic situations.

This procedure enhances overall safety and efficiency, providing pilots with clear guidance on how far to remain from the marshal radial while executing their ascent or descent. Adhering to this practice mitigates risk and increases operational predictability in air traffic management.
