How do pilots talk to ATC?

The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.

What type of communication is used between ATC and aircraft?

Explanation: The communication between an aircraft and an ATC is half duplex meaning only one can speak at a time. The ATC asks or gives guidance for the aircraft, which the pilot has to fully hear before he can respond. If he responds before, the signal is not received by the ATC. 11.

What is aircraft radio communication?

VHF communication radios are the primary communication radios used in aviation. They operate in the frequency range from 118.0 MHz to 136.975MHz. Seven hundred and twenty separate and distinct channels have been designated in this range with 25 kilohertz spacing between each channel.

What do radio pilots say?

When communications between aircraft and the ground switched to a radio-based format, the use of ‘R’ to mean ‘received’ carried on. However, as is common today with the NATO Phonetic Alphabet, pilots and controllers used short, easily discernible words, rather than the letters themselves, to increase clarity.

Why does military say Niner?

Aviators often speak “pilot English” to avoid miscommunications over radio transmission. “Tree” for instance, means three, “fife” is the number five and “niner” means nine, says Tom Zecha, a manager at AOPA. The variations stemmed from a desire to avoid confusion between similar-sounding numbers, he says.

Why is nine said as Niner?

Changing “nine” to “niner” adds another vowel sound, which may help distinguish them when radio reception is poor. Show activity on this post. “Niner” is spoken for the numeral 9 to avoid it being mistaken for 5. This would be better as a comment once you gain enough reputation.

Who uses high frequency (HF) communications?

Our highly reliable High Frequency (HF) communications systems support both shipborne and fixed-station platforms used by the U.S. Navy and U.S. Coast Guard (USCG). Thales is proud to be the HF system of choice for the USCG to include the new Sentinel Class Fast Response Cutter.

What is high-frequency communication?

High frequency allows for quicker and direct communication techniques. With a combination of other techniques such as adaptive systems, high-frequency communications can be as effective as satellite and telephone communications.

What is the future of HF communication?

HF communication using digital modes like FT8 is an example of how techniques evolve with digital communications. The ham and hacker communities have stated that evolving methods could enhance global communications while improving the use of limited spectrum. There is a trade-off, however.

Is it possible to use high frequency waves for long-distance communication?

Therefore, direct long-distance communication is possible with the help of high-frequency waves. However, variable conditions such as season, sunspot cycles, proximity to the solar terminator for both sender and receiver equipment, polar aurora and solar activities can limit the use of the high-frequency spectrum.
