摘要: Non-precision approaches (without vertical guidance) are known to expose aircraft greater risk of CFIT (controlled flight into terrain). One solution consists RNAV (area navigation) with a computer-generated lateral and path, which use the aircraft's management computer fly an approach without any conventional ground-based radio facilities. We studied 22 pilots who flew 66 real approaches. Of special interest us were human factors safety implications using this new technology for old problem. The high level automation used brings it potential surprise (e.g. unexpected level-offs at go-around altitude) extra monitoring requirements, especially pilot-not-flying. There is also effect low temperature that makes shallower as compared ILS (instrument landing system). Pilot acceptance measured in study high, perceived mental workload both pilot flying not-flying low. This can be explained large part by shift from double-checking height against distance traditional non-precision approaches, pattern matching (aircraft symbol/reference) during
