If the crew has decided to use the radio to communicate, which hand signal should they expect the engineer to accept?
Answer: Stop signalFeedback: - The engineer is not expected to respond to hand signals when the crew is working with the radio. - Any movement of the crew's hands or arms are irrelevant unless it is a signal to stop. - A job safety briefing is required before crew members on the ground can decide to switch back to hand signals.
