Aviation - what is the en route or on route freqency in the USA?

Question

In Canada, we monitor 126.7 when there are no other frequencies to monitor or when not close to any airports. FSS will listen to this frequency, and position reports are usually made on this frequency. Is there such a frequency in the US?

Answer 1

As far as I know it is the same in the US.

I am Canadian too.

Answer 2

When flying VFR over most of the USA, you're never far from an airport, and most pilots monitor the local Unicom frequencies, which can be found on your sectional navigation charts.  The official air-to-air frequency is 122.75, and the official emergency/distress frequency is 121.5.

When flying IFR, or with VFR flight following, you are assigned a specific radio frequency to maintain contact with the regional air traffic control.

Answer 3

In the USA many airlines and other operators monitor 121.5 "emergency" frequency and 122.0 "flight watch" in addition to assigned ATC channels. I'm a corporate pilot and fly all over the country, and I regularly monitor both in addition to my assigned frequency. As a general rule, I also tune in the closest airport or approach control frequency for a "heads up" on conditions ahead and to keep tabs on departing traffic. When flying VFR in my own aircraft, I usually monitor the local center, approach, or tower frequencies too, along with 121.5 and 122.0 on long flights when communications aren't required. In certain  parts of the country and Alaska with lots of VFR traffic in uncontrolled airspace, there are often local frequencies assigned for pilots to monitor when flying heavily traveled routes, particularly along valleys and in "tour heavy" areas...these freq's are usually 121.7, 121.8, or 121.9.
