Ground guidance relies on clear, standardized communication between the marshaller and the aircraft. A marshaller directs taxi and movement on the ground using visual signals—hand signals, wands, or flags—and can supplement or replace them with radio communication to confirm instructions and receive the pilot’s readbacks. This dual approach covers both when the crew can see the signals and when radio contact is needed to ensure unambiguous guidance, especially in busy airports or low-visibility situations.

Autopilot guidance on the ground isn’t applicable, as autopilot controls flight paths, not taxiing, and isn’t used for marshalling. Relying on ground crew shouting alone isn’t standard practice because shouting can be misheard in noisy airfields and lacks the precision and universality of established signals. Visual signals alone can be insufficient in some conditions where radio communication provides necessary clarity and confirmation. Therefore, using signals or radio best fits real-world ground guidance.
