The hand signal to indicate that the airplane is safe to approach involves the marshaller raising both arms above their head with light wands pointed straight up. This signal clearly communicates to ground personnel that it is safe to proceed toward the aircraft.

In this position, the arms are typically well above head level, ensuring that they are easily visible from a distance. This action signifies to the team that all necessary precautions have been taken, and it is appropriate to approach the aircraft for further operations, such as unloading or preparation for departure.
