1、AEROSPACE RECOMMENDED PRACTICEARP1061REV.AIssued 1971-11Revised 1999-04Superseding ARP1061Altitude Alerting Devices and SystemsFOREWORDChanges in the revision are format/editorial only.1. SCOPE:This SAE Aerospace Recommended Practice (ARP) provides performance criteria for Altitude Alerting Devices

2、and Systems. These devices can be self-contained or receive remote altitude information and can have integral or remote barometric corrections. Only the generation of the alerting signals is covered by this recommended practice and not the details of the visual or audio alerts operated by these sign

3、als. It is recommended that the systems operational correspondence between the selected altitude settings of the Altitude Alerting Device and the Altitude Level Indication normally used to control the aircraft should not exceed 250 ft RSS throughout the operating range of the device.1.1 Range of Alt

4、itude:This recommended practice provides for operational performance up to 80,000 ft of altitude based on pressure altitude, radar altitude or radio altitude in any combination or singular inputs.1.2 This device should contain or accept inputs of altitude, equal to that information displayed and use

5、d by the pilot for height control of his aircraft, in increments of not greater than 100 ft of indicated altitude. This device should provide for audio/visual warning signals when the flight altitude deviates from the preselect altitude or height level and for approaching and/or departing a preselec
