What should controllers avoid issuing as a frequency change to during air taxiing, hovering, or low-level flight?

During air taxiing, hovering, or low-level flight, controllers should avoid issuing a frequency change to single-piloted helicopters. This is because single-piloted helicopters often require more attention from the pilot due to the unique challenges associated with their operation at low altitudes.

In these phases of flight, pilots need to maintain a heightened sense of situational awareness, which is critical for safely navigating areas with potential obstructions or other aircraft. Issuing a frequency change could distract a single-piloted helicopter pilot, drawing their focus away from essential operational tasks, such as monitoring their surroundings or managing the aircraft's performance during these crucial phases.

In contrast, multi-piloted helicopters have an additional crew member who can manage communications, making it safer for them to switch frequencies without compromising situational awareness. Similarly, jets, whether single or multi-piloted, are typically less vulnerable during these low-speed operations due to their structural and operational characteristics, allowing for more flexibility in communication.
