Every country has a governing authority that allocates a specific operating frequency for a small satellite mission. The International Telecommunication Union (ITU) Radio Regulations regulate the utilization of radio frequencies and the law of nations scale radio-communication services. However, the proces...
In the contiguous US, the base station callsign is "San Francisco Radio" except on Gulf Net, Maritime Net and Mex Net which are "New York Radio." ARINC Voice Service (this page has current HF/VHF coverage maps) ARINC Frequencies in the NE US VHF en route frequencies changed effective ...
HF COM– High Frequency Communication. HIRF– High intensity radiated field. HP– Horsepower. HPA– High-power amplifier. HUD– Head-up display. Hz or Hertz– Cycles per second, used to describe radio frequencies; usually with the prefix k for kilo (one thousand), M for mega (one million...
In reality, even with 30 such precious aircraft, plus a very elaborate network of shore-based HF/DF stations, sea-going SIGINT spy-trawlers (AGIs), HUMINT assets, tattle-tale destroyers and even satellites, the Soviet Navy still had considerable coverage gaps even close to its operating areas,...
(a) uses frequencies from 960 to 1215 MHz (almost 10 × higher than VOR) so that smaller antennas can be used; (b) employs a multi-lobe radiation principle which improves bearing accuracy; and (c) enjoys equipment economics as a result of using the same radio frequencies for range and ...

VOR 1 and VOR 2 Frequencies are set in the banner. The MD-80 users will be nodding and saying "Yeah, yeah.. not to much different is it", but there is a lot of different detail or minute in this MCDU to study... a lot is straight forward, but still different, so be aware....
To the naive observer, aircraft radio communications can be as incomprehensible as a foreign language. As with any language, understanding what is said requires not only a knowledge of specific terms, but also a familiarity with the context in which the communication occurs. The novice, whether ...
And it is shorted concentrically with a set of conductive vias. By adjusting the parameters of the antenna, the dual resonant frequencies for two modes ... L Sun,BH Sun,GX Zhang,... - ,38,(2013) 被引量: 0发表: 2013年 CONVERTER FOR AN AIRCRAFT, and AIRCRAFT The present invention rela...
[0026] This display 300 allows users to access to past frequencies previously used along the flight. The historical radio frequencies list 308 provides a "life-line" in case pilots lose contact with the controller while changing frequencies. The historical frequency list 308 allows for quick error...
