From our Learning Centre lesson, The Basics of Flight, in this video we discuss air pressure and how to generate lift. http://learn.sigmarockets.com/lessons...
25 sty 2024 · A flight level (FL) is a standard pressure altitude, expressed as three numbers. Aircraft flying on flight levels all measure their altitude from the same pressure setting, 1013.2 Hpa (or 29.92 InHg).
As the aircraft climbs or descends, passengers may experience discomfort or acute pain as gases trapped within their bodies expand or contract. The most common problems occur with air trapped in the middle ear (aerotitis) or paranasal sinuses by a blocked Eustachian tube or sinuses.
CS 25.1517 Rough air speed, VRA; CS 25.1519 Weight, centre of gravity and weight distribution; CS 25.1521 Powerplant limitations; CS 25.1523 Minimum flight crew; CS 25.1525 Kinds of operation; CS 25.1527 Ambient air temperature and operating altitude; CS 25.1529 Instructions for Continued Airworthiness; CS 25.1531 Manoeuvring flight load factors
The flight levels correspond to the altitude in 100-ft increments (hectofeet) above the pressure surface of 1,013.25 hPa calculated according to the standard atmosphere. For example, FL050 is the pressure surface 5,000 ft above the pressure surface 1,013.25 hPa.
22 maj 2015 · It’s easy to take flying for granted. We hop on-board a comfy airliner and fly high in the stratosphere without giving breathing a second thought. The aircraft’s pressurization system makes it possible. Here’s how the magic works….
Poziom lotu ( ang. Flight level) – powierzchnia baryczna o określonym ciśnieniu oddzielona od innych takich powierzchni o określoną różnicę ciśnienia i odniesiona do specyficznej wartości ciśnienia zwanego ciśnieniem standardowym o wartości 1013,25 hPa (760 mm Hg).
