A higher altitude, low pressure area, higher temperature and high humidity all For example at 15°C and with ISA QNH the lapse rate will be: 96 (15+273). At mean sea level (msl), the pressure = 1013.25 hPa and temperature = 15.0 degC. An altimeter set to the airfield QNH reads the elevation of the airfield when on conditions are significantly different from ISA: i. e. at 'hot and high' airfields.
High to Low QNH Effect on Indicated Altitude, Ask a Flight Instructor
6 Sep 2014 Regional or airfield pressure setting (QNH) is set when flying by. after levelling at FL 070, it flew into the side of a 6608 foot high mountain. 31 Jan 2013 QNH is the pressure at mean sea level, reduced from QFE by applying In an area of high pressure the air is generally stable and is usually.
