If desired verify the security of the super barrier design in edge, protected location, according to mode below, fly:
In center line both sides, respectively according to the desired properties navigation grade biasing flight (direction is the same with normal procedure with height) of twice, verify that whether identified barrier data are correct, whether super barrier remaining meets the demands; And observe the barrier (not being identified at the barrier on program chart) that whether has " newly ", if there is " newly " barrier, need to record its position.
If aircraft is provided with GPWS(ground short range warning system in addition), whether pilot/checker will note observing has warning information to occur.If there is warning information to occur, repeat flight, observe whether still have warning information, if still exist record occur warning information position (longitude, latitude, highly).
(3) motor-driven zone design security verification
Object: by the designed motor-driven region of practical flight appraisal procedure safe enough whether.
Method: carry out circumference according to program motor-driven, verify whether safety of motor-driven region, will assess especially for the type that will adopt this program safety whether.The flight check in motor-driven region will be carried out respectively with night by day.
(4) airport sign and runway light
Object: confirm that by practical flight airfield runway sign and light meet flight needs.
Method: by daytime and two kinds of modes of night flying, whether the runway light that the visualization of take is main inspection target airport and sign meet the needs of programed flight.
(5) communication and radar cover checking
Object: by practical flight, check earth-space communication and the radar coverage condition of each leg.
Method: identical with the covering method of calibration of VHF communication equipment (VHF) and radar in traditional subject, whether record has VHF and radar to use in flight course.
(6) other performances of program
Object: the readability of appraisal procedure, ease for use.
Method: by using mission program, pilot judges whether its design is succinct, understandable.The complicacy of program chart has dropped to minimum, to adapt to pilot's memory capability.Pilot thinks whether working load can be accepted.
Finally, according to the result of the real-time analysis of flight check data and information aftertreatment, provide flight check report.
This method, according to International Civil Aviation Organization's standard design, meets related needs, for the verification of two stadimeter RNP mission program provides reference method.
