Analysis of Techniques for Aircraft Ground Guidance at Airports

摘要

Assuming future use of runway approach and flareout guidance in extremely low visibility, the report describes an investigation of suggested techniques for aircraft guidance during landing and takeoff roll and taxiing in poor visibilities down to zero-zero conditions. The techniques examined are: ILS localizers (including DME); gyro compasses and inertial systems; infrared; magnetic cables; aircraft radar; light and line patterns from conventional light sources including lasers and radioactive materials; and miscellaneous techniques including wheel tracks. These systems are judged relative to the operational requirements and considerations, including some economic analysis. It is concluded that, for landing and takeoff ground operations, improved ILS localizer plus DME offers the best solution. For taxiing operations, magnetic leader cables show the most promise. Research programs are indicated as being necessary for both ILS/DME and leader cables. (Author)
