SCOPE:This document specifies requirements for an Airborne Landing Guidance System (ALGS) electronic device. This equipment shall derive relative

2、aircraft position and situation information for flight along precision three-dimensional paths within the appropriate coverage area. The precision three-dimensional path may be an ILS straight-in look-alike path or a complex, curved path. The requirements are applicable to electronic devices capable

3、 of receiving signals or other information from one or more sources, including but not limited to ILS, MLS, GNSS, or IRU inputs.2.

10、 2 -3. OPERATIONAL REQUIREMENTS:3.1 General Requirements:Manually Controlled and Automatic Flight: The ALGS shall be capable of providing information that allows appropriate guidance for both manually and automatically controlled flight.Crew Workload: During critical phases of an approach or departu

11、re, the use of ALGS derived guidance shall not increase crew workload above that required using other acceptable guidance sources. During any phase of flight, the workload should not interfere with normal crew vigilance required for safety.Flight Deck Integration: The ALGS related airborne equipment

12、, installed in the flight deck, shall meet the requirements established by flight deck standards for instrumentation and controls, including human factor considerations.Information and Guidance Integration: ALGS derived guidance shall be smooth and ALGS situation information shall remain coherent wh

13、en transitioning from enroute navigation to ALGS signals and throughout the entire approach while within the appropriate ALGS signal coverage.Display and control of barometric altitude/height as the basic system of altimetry shall not be affectedby the availability of ALGS derived altitude. ALGS der

14、ived altitude may be used for guidance and control along the portion of the final approach course route in which the final descent has been programmed.3.2 Functional Requirements:3.2.1 Types of Flight Paths: The ALGS shall be capable of providing information that allows appropriate guidance for stra

15、ight-in precision (ILS-LOOK-ALIKE) approaches, landings, and missed approaches.Where the implemented guidance system permits, the ALGS shall be capable of providing information that allows appropriate guidance for the following phases of flight: STARsThree-dimensional multiple-segment curved path ap

16、proachesComputed centerline aproachesLanding rollMissed approachesDuring the execution of a missed approach, the ALGS system shall be capable of providing information that allows appropriate guidance and path information from any point on the approach path to the runway threshold.SAE ARP4102/12 Revi

17、sion A- 3 -3.2.1 (Continued):If the ALGS uses multiple sensors for different sections of the approach and missed approach, the system should utilize appropriate navigation sources for each section.Where the implemented guidance system permits, the ALGS may also be capable of providing information th

18、at allows appropriate guidance for the following phases of flight:Takeoff roll/initial climbDepartures/SIDs3.2.2 Airborne Landing Guidance System Electronic Device: The final approach course, the glide path, and the missed approach course may be automatically programmed or manually selected. In eith

19、er mode, the final approach course and the initial segment of the missed approach course shall be able to be referred to both true and magnetic North, whichever is required for the instrument procedure. The glide path of the final approach course shall be a constant, earth-referenced descent.If the

20、ALGS is in a manual mode, the crew shall select values for the final approach course, the glide path (if applicable), and the missed approach course. A means shall be provided to prevent selection of values outside of acceptable limits.If the final approach course, the glide path angle, and/or the m

21、issed approach course selected in the receiver are different from the values received through a data link, an alert shall be presented.3.2.3 Database Requirements: The NAV data base shall contain sufficient data to completely define the approach procedure(s) that shall be used. The crew should not b

22、e required to insert additional navigation data to conduct an approach unless modifications are required by air traffic control.It shall be possible to verify the data used to define the approach and the landing runway.Verification of the data shall not affect navigation and guidance.For an approach

23、 on a given runway, once the aircraft has passed the final approach fix, the final approach path shall not be modifiable by the crew, and, in this case, if the crew attempts to modify the path, the crew shall be clearly informed of the reason why his attempt has failed. Before the final approach fix

24、, the approach path may be modified within applicable ATC constraints.3.2.4 Safeguards:Tolerance to Electronic Transients: Transients or loss of electrical power usual to normal operations (including generator or bus transfer) shall not erase or alter the flight plan route, display configuration, or
