The goal of H2FLY, a company that develops hydrogen fuel cell technology, is to “drive emissions-free flight.” H2FLY was founded in 2015 by five engineers from the German Aerospace Center in Stuttgart and the University of Ulm. H2FLY predicts that, in just a few years, hydrogen-electric aircraft will be able to transport 40 passengers over …

The microwave landing system (MLS) has been developed to overcome some of the problems and limitations associated with the ILS system. The MLS system currently being deployed is called a time-reference scanning beam microwave landing system, or TRSB. The ILS provides one narrow flight path and operates at VHF/UHF frequencies, whereas the MLS provides a …
Since before World War II ADF equipment has been used on aircraft as an aid to navigation. The function of an ADF system is to enable the pilot to determine the headings, or direction, of the radio stations being received. The ADF system operates on a frequency range of 90 to 1800 kHz, a range …
Have you ever wondered how pilots know where they are going? Airplanes travel thousands of miles across the sky, and although the horizon looks the same everywhere, they still manage to reach their destination with precision. Piloting an airplane to its destination is more like sea navigation than driving a vehicle such as a car: …
Transponder for aircraft identification In aeronautics, planes have transponders to help with their identification by radars and also as a system of collision avoidance The first transponder systems were developed in aeronautics by the British army and by the American army during the Second World War under the name of Identification friend or foe (IFF) …
The use of radio equipment and avionics, in general, has increased markedly for all types of aircraft during the past thirty years. One of the reasons for this increase is the Federal Aviation Administration’s (FAA) requirement, that all aircraft operating in high-traffic areas be equipped with a two-way radio for communication with air traffic controllers …
At the beginning of aviation, navigation was done by sight. In the event of degraded visibility conditions, aeronautical headlights marked out certain sections of roads regularly taken. During the second half of the 20th century, radio navigation developed. At the beginning of the 21st century, air navigation makes extensive use of GPS. Types of navigation …
An airliner is a type of aircraft for transporting multiple passengers and air cargo in commercial service and used in-flight activity for compensation or hire. Such types are most often operated by airline companies and assessed by the State Tax Commission. This aircraft category is divided into four main types : NARROW-BODY AIRPLANE : Also …
MCDONNELL DOUGLAS F-15 EAGLE The F-15 was the US answer to the MiG-25. In 1972, the F-15A took to the air for the first time. It was the prototype for what would become a flagship fighting plane for the US Air Force just two years later, when the first F-15 Eagle was delivered in November …
