Do I need a VHF or CB radio?

In order to talk to an air plane from the ground you would need a VHF radio rather than an CB? And of you would have to have one of each one on the plane and another on the ground.Do I need a VHF or CB radio?
OK, if you are talking to someone from the ground to an airplane privately, you can CB, VHF, UHF, HF, the new family band radios, or two cups and a real long piece of string.



Yes, you would need one radio on the airplane and one on the ground.



VHF is used to communicate to ATC. I don't know what you are trying to do, so to answer this question we'd need more info.
Yes we use VHF radios on aircraft. Not Citizens Band (CB)

and yes for a pilot to communicate with a ground station there must be a VHF radio on board the aircraft as well as one in the ground station, %26amp; in order to communicate each must be tuned to the same frequency.Do I need a VHF or CB radio?
you need a VHF AM airband radio, be carefull though cos there are only certain frequencies you can speak on. you can buy them from companies such as icom. as long as theres a standard VHf on the airplane you can just tune into that frequency and chat away
The person on the ground and the person in the air both need to have a transmitter/receiver that operates on the same frequency. You have a choice of solutions; two are listed below:

- VHF aviation band radios are already installed in all aircraft (except certain ultralights or sport aircraft). You can buy a hand held radio (www.sportys.com or www.icom.com) for the person on the ground. Handhelds have less power, but you likely want to talk to someone reasonably close anyway. You will want to be particularly careful about what frequency you use. You will want to stay off local ATC, weather, unicom, and flightwatch frequencies (to name a few), and most of all, STAY OFF "GUARD" 121.5 MHz, but your pilot friend and you can select a frequency. I lent a spare handheld to a friend whom I would visit often. Before taking off, I'd call by phone to give a rough ETA and would have her monitor the local unicom frequency. When she heard me call in at 5 miles out, she'd jump in the car and pick me up at the airport :-)



- Cell phones - these are great since just about everybody has one. You are supposed to turn them off in powered aircraft (may interfere with navigation devices) but it is noteworthy that you can buy aviation headset adaptors to plug into cell phones. We used them all the time in gliders (where you didn't have to contend with engine noise). Of course, the ground based antennas for the individual cells in the network were designed for ground-based users so the aerial coverage can be a bit spotty.



I'm told that the networks get a bit miffed if you are using a cell phone in a plane as you switch from cell to cell quickly and it provides an additional switching burden. That wasn't much of a problem in a glider (60-80mph) which is car highway speed, but it is pretty obvious in a powered aircraft at 150 knots or faster.Do I need a VHF or CB radio?
I would like to say there are three methods of communication possible.



HF communication



It provides wide range communication its is operated within the range of 3MHz-30MHz. Pilot uses this mainly for getting recorded meteorology readings of designation airports. Rarely communicates.



VHF communication



It provides short range communication. VHF spectrum falls within the range of 30Mhz-300MHz. This is method is used for communicating to ATC for landing, parking , taxing and take-off. The operational range falls between 118.0Mhz to 132.0Mhz for commercial aircrafts, which are Amplitude Modulated (AM wave). Emergency frequency is 121.5Mhz also known as International Air Distress (IAD) and for military aircraft the emergency frequency also known as Military Air Distress (MAD) is 243.0MHz.



Cockpit-Ground Communication



This is a headset %26amp; mic jack. located at the ground crew contol panel which is located in a place nearby the front wheel. When the audio control panel (ACP) in cockpit is enabled to ground, cockpit and ground crew can communicate through this while towing, engine run up, any testing needs supervision from outside.



Public are not allowed to operate on the frequency spectrum specified to aviation communications.
