@exam.revolution: QFE, QNH, QNE, QFF… can you remember the difference? These four Q Codes show up regularly in Meteorology and Air Law exams, yet many students mix them up. A quick recap: • QFE = Pressure at the airfield elevation • QNH = Pressure reduced to mean sea level • QNE = Standard setting (1013.25 hPa / 29.92 inHg) • QFF = Actual pressure at sea level The challenge isn’t memorising the definitions. It’s knowing which setting to use and when. That’s exactly what catches students in exam questions.
