English to French Tech/Engineering Aerospace / Aviation / Space remorquage d\'aéronefs

Bonjour à tous,
Wing walkers must be positioned outside and slightly behind the wingtips prior to pushback.
Upon receiving the ready signal from the tractor driver/headset operator, wingwalkers will clear the area (ensure there is no encroachment), and raise their outside arm (arm farthest away from the aircraft) above their heads.
They should walk facing the direction of aircraft movement while maintaining visual contact with the driver/Headset person.
Je ne suis pas sûr de bien exprimer le mouvement suivi par ces agents par rapport à l'avion.
marcher dans le sens de manœuvre de l'aéronef ?
Merci de votre aide.
