Pressure altitude is the height above the standard datum plane (SDP). The aircraft altimeter is essentially a sensitive barometer calibrated to indicate altitude in the standard atmosphere. If the altimeter is set for 29.92 “Hg SDP, the altitude indicated is the pressure altitude—the altitude in the standard atmosphere corresponding to

High to low look out below, low to high clear the sky! If you have never heard that saying before you are probably pretty confused right now. Let me help ease that confusion and explain that today we are discussing altimeter errors when flying in areas of changing atmospheric pressures.
…2017 was a big year for us at ASA. We’ve been busy, releasing new editions of all three Pilot’s Manual textbooks (Flight School, Ground School, and Instrument Flying), William Kershner’s The Student Pilot’s Flight
…Have you ever wondered how pilots are able to determine the location of an airport at night or in reduced visibility? Well the answer is actually very simple. At night, the location of an airport can be determined by the presence of an airport rotating beacon light like the one
…Today, we’re sharing an excerpt from The Pilot’s Manual: Instrument Flying. This post is a follow-up to last month’s IFR: The Instrument Landing System (ILS).
To assist pilots transitioning to a visual landing at the conclusion of a precision instrument approach, precision
…Today’s post comes from the Pilot’s Handbook of Aeronautical Knowledge (FAA-H-8083-25), which is now available as an eBook.
Runway conditions affect takeoff and landing performance. Typically, performance chart information assumes paved, level, smooth, and dry runway surfaces. Since no two runways are alike, the runway surface
…Today, we’re featuring an excerpt from The Pilot’s Manual: Instrument Flying (PM-3).
Automatic Dependent Surveillance-Broadcast (ADS-B) is a surveillance technology being deployed throughout the entire National Airspace System. ADS-B enables improved surveillance services, both air-to-air and air-to-ground, especially in areas where radar is ineffective due to
…You have been asking us for an aviation flight computer with a backlit display, and trust us we’ve been listening. But we thought, if we are going to design a flight computer with a backlit display, why stop there? Wouldn’t it be cool if we had a backlit keypad as
