Air Navigation 空 中 領(lǐng) 航 學(xué) 43 Wind Velocity 風(fēng)速向量 The wind velocity is nearly always expressed as a five or sixfigure group。 Air Navigation 空 中 領(lǐng) 航 學(xué) 55 Traffic Separation（ 空中交通間隔 ） Safe traffic separation requires all aircraft in the same vicinity to use the same QNH altimeter setting. Air Navigation 空 中 領(lǐng) 航 學(xué) 56 Area QNH To ensure a proper vertical separation , all aircraft operating in the same general vicinity must use the same altimeter subscale setting, the area QNH. Area QNH settings are used by all aircraft operating at or below 10,000 ft AMSL (transition altitude). The area QNH is a forecast value that is valid for a period of 3 hr and normally applies throughout an area QNH zone. Before flight, the area QNH will be available through the AVFAX system. In flight, the area QNH will be available from ATS. Air Navigation 空 中 領(lǐng) 航 學(xué) 57 Accuracy of Area QNH Setting Area QNH values are required to be accurate to within 5 hPa of the actual QNH at any lowlevel point (below 10,000 ft AMSL) within, or on, the boundary of their respective AQZs during the period of validity of the forecast. The indicated altitude will be within 177。 FL115 is not available for level flight when the Area QNH is less than 997 HPA, and so on. To ensure that the 1,000foot buffer of the transition layer is maintained, the lowest FL available for cruising bees higher and higher with a progressive decrease in the value of the area QNH.

VFR Altimeters With an accurate QNH set, a VFR altimeter(s) should read site elevation to within 100FT (110FT at test sites above 3,300FT) to be accepted by the pilot as serviceable. Air Navigation 空 中 領(lǐng) 航 學(xué) 67 Accurate QNH and Site Elevation A QNH can be considered accurate if it is provided by ATIS, Tower or an automatic remotereporting aerodrome sensor. Area or forecast QNH must not be used for the test. Site elevation must be derived from aerodrome survey data published by Airservices or supplied by the aerodrome owner.
