摘要: An aircraft upon approaching a runway for landing receives "measurable signal" from transmitter located at the far end of active runway. The strength this is indirectly proportional to distance between and transmitter. After signal converted digital data, computer uses in conjunction with preprogrammed performance characteristics make "safe" or "unsafe" decision. This decision communicated pilot by means special meter on instrument panel. "safeness system" may be coupled aircraft's automatic braking system provide correct amount deceleration. If properly enabled, will initiate go-around another try should current attempt unsafe. A similar procedure would also abort takeoff not reach rotation speed time clear an obstacle
