What is ground frequency used for?
However, the frequency 123.45 MHz is designated as an air-to-air VHF communications frequency to enable aircraft engaged in flights over remote and oceanic areas out of range of VHF ground stations to exchange necessary operational information and to facilitate the resolution of operational problems.
What is ground frequency?
All FAA facilities monitor the emergency frequency, 121.5 MHz. Typical unicom frequencies are 122.7, 122.72, 122.8, 122.97, 123.0. 123.05, and 123.07 MHz. At controlled airports, ground frequencies are likely 121.3, 121.5, 121.7, and 121.9. Note that all begin with 121 and end in an odd tenth.
What are the frequencies used for ship to aircraft communication?

What are the radio frequencies for test flights?
Test flight frequencies are sprinkled throughout the VHF aviation band between 123.125 MHz and 123.575 MHz. Within this range are 123.4 MHz and 123.45 MHz, colloquially referred to as “Finger” and “Fingers” respectively. In some circles, these frequencies have been used for casual air-to-air communications.

What are the frequencies for air traffic control?
All flight service station (FSS) frequencies in the 121.975 to 122.675 MHz band will be assigned on any selected 25 kHz channels. c. New air traffic control or advisory services that require assignments in the 118.000 to 136.975 MHz band will be assigned 25 kHz channels only.
