What are the most common uses of radio communication when flying? What are the most common uses of radio communication in aviation? I know that many aviators communicate with the people in towers with radio, but what do pilots say to the people in the towers and vice versa? What do pilots and ATCers communicate about.
It will be hard to list everything that is said, but I can try to start with some of the basic examples:


Pilot is ready to taxi to the Runway
P: Tower, N12345, has information Tango, at South Parking, ready to taxi.
T: N12345, taxi to runway 13 via Alpha, Delta.



Pilot is ready to take off
P: Tower, N12345, is ready to go at runway 13. Request SouthEast Departure
T: N12345, cleared for takeoff, SouthEast Departure approved.



Pilot wants to cross another airspace
P: Tower, N12345, is 10 miles to the East, 1,500, request transition east-to-west
T: N12345, transition approved as requested.



Pilot wants to approach an airport to land
P: Tower, N12345, is 10 miles to the South, 1,500. To Land
T: N12345, make Left-traffic for runway 17; report a 2 mile final
