The ILS works by sending 2 beams up from the landing runway, one telling the pilots if they or high or low and the other telling them if they are left or right of the runway centreline. The radio beam signals are interpreted by the aircraft's computer systems and relay this information to the pilots.

My aircraft is equipped with a Stratus portable receiver and an approved ADS-B out transponder. Why do I not see traffic information displaying on ForeFlight Mobile? Why do I see a "ghost" aircraft mirroring me in ForeFlight Mobile while I am using my Stratus portable ADS-B receiver? View all 4 articles.
Everybody has a favorite band that they listen to, and different antennas work better on different frequencies. But the fact is, the general principles remain the same for everybody. The object of an antenna SYSTEM, is to deliver as much signal as possible to the antenna jack on the back of the radio at the frequency youre listening to.
All outdoor antennas work better than indoor ones, and window and set-mounted antennas have higher gain and work better than built-in ones. Bandwidth. An antenna's bandwidth is the range of frequencies (or wavelengths, if you prefer) over which it works effectively. The broader the bandwidth, the greater the range of different radio waves you ...
The TCAS has two antennas which could be used to scan the airspace around the aircraft at a 40 miles (64.4km) radius horizontally and 9900 feet (3km) upwards and downwards vertically so that it could search for a transponder of the intruders. These transponder signals are used to search for closure rate and relative altitude (in case it is ...
A cellular modifier, also known as a cellular repeater, is a form of bi-directional amplifier that improves your phone's cell reception. The cellular system contains a door antenna, whose purpose is to receive and transmit signals from a cell tower near you, coaxial cables, an indoor rebroadcast antennae, and a signal amplifier.
Fig. 1 presents an antenna installation under an aircraft composite structure. The composite material could impact on the antenna performance and, consequently, change its electromagnetic properties such as impedance matching, operational bandwidth, radiation pattern, gain and so on.
The main purpose of this Modeling and Simulation of Antennas course is to gain a true understanding of the principles of antenna theory and the major antenna modeling methodologies. You will review antenna architectures and modeling theory, with an emphasis on various methods of modeling the antenna architectures, as well as explore major modeling methods, with a focus on commercial modeling ...
A tin can waveguide antenna, or Cantenna, may be just the ticket. This design can be built for under $5 U.S. and reuses a food, juice, or other tin can. Also, here's the ten cent modification you can do to double your radio's range. I am not an electrical engineer, nor do I have access to any fancy test equipment.
It simply requires a connection to a digital HDTV antenna, positioned anywhere in your home, ideally placed for optimal reception. You can use the Fire TV Recast to record any of the over-the-air (OTA) programs currently available to you via a digital HDTV antenna in your area, and play them back on any or all of your compatible devices.
Localizer type directional aid. A localizer type directional aid (LDA) or Instrument Guidance System (IGS) is a type of localizer -based instrument approach to an airport. It is used in places where, due to terrain and other factors, the localizer antenna array is not aligned with the runway it serves. In these cases, the localizer antenna ...
When most laypeople think of aircraft antennas, they assume they are there for effective communication, which is correct. Com antennas are usually mounted on either the top or bottom of the aircraft, and their only concern is being affected by the shadowing of the fuselage. Each com transmitter has its own antenna, and the antenna are strategically placed mainly because their range and coverage can be negatively affected if positioned incorrectly.
How Planes Work. Airplanes fly when the movement of air across their wings creates an upward force on the wings (and thus the rest of the plane) that is greater than the force of gravity pulling the plane toward the earth. The physics behind this phenomenon was first described by Daniel Bernoulli, an 18th century Swiss mathematician and ...
