Series 9900 Pushback Systems (Wireless)

Designed for Ground Crews
Series 9900 Wireless Systems for pushback operations are designed to provide ground crews with enhanced mobility and situational awareness without being tethered to the aircraft or pushback apparatus. Pushback operations are handled with greater efficiency and turnaround time at the gate is improved.

The Series 9900 System can be configured for a single user (tug operators working alone with no wing walkers) or as a 3-position system to facilitate communication between the tug operator and wing walkers. Rugged, reliable system components include pushback gateway and interface cord for connecting to the aircraft service panel, noise-attenuating headsets and belt stations shown below.
