Introduction

The RLG GIS204-3 Automated Guide-In System was developed (in 1969) to guide in and stop aircraft in precise positions at airport terminals. New airport design generally calls for nose-in docking with precision positioning of aircraft to loading bridges and fuel pits. The RLG System is designed to this concept, and with the addition of wide-bodied aircraft, to accommodate all aircraft types on a single docking device, eliminating error factor involved with changes in height of aircraft due to variation of gross weight. The system complies with ICAO Annex 14 recommendations.

Parking tolerance to loading bridge with aircraft having pilot tubes forward of the passenger doors is extremely critical. The RLG System holds a tolerance of + or - 6 inches.
