Contact and Handover are not referenced here any more: Every station handles it the same way - see the section Study_Guide:Radio_Telephony#Contact_-_messages_-_handover for details.
Sometimes, pilots come up first with a radio check:
AUA251: Delivery, AUA251, Radio Check ATC: Austrian 251, Wien Delivery, read you 5 by 5
(where the numbers mean "loud" and "clear": 1 by 5 is very low, but clear; 5 by 1 means very loud, but almost unreadable.)
AUA251: Wien Delivery, Austrian 251 [guten Abend], gate C31, Fokker 100, requesting clearance to Munich, Info A [on board]. Syntax= <called station>, <myself>, <position>, <aircraft>, <request>, <ATIS information received>
ATC: Austrian 251, [Wien] Delivery [servus], cleared München SITNI4C, [climb 5000ft,] squawk 4600, info A [correct]. Syntax= <calling station>, <myself>, <clearance destination>, <SID>, [<init. climb altitude>], <squawk>, [<ATIS confirmation>]
Wien Delivery does not need to say initial climb altitude - it's in the charts. 90% of all aircraft ask or mess it up, so you might as well say it right away. At LOWI for example, the charts say "Initial climb altitude: by ATC", so you have to add it. IN LOWS, there are different climb altitudes per SID - you have to say it.
Pilots must read back the clearance, and ATC must acknowledge correct readback (mostly linked with #Handover/Handoff):
AUA251: cleared München SITNI4C, climb 5000ft, squawk 4600, info A on board, Austrian 251. ATC: Austrian 251, readback correct, contact Ground 1121,6 bye. AUA251: contacting ground 121,6, bye.
On very busy events (like Finally Austria), Wien Delivery can put in his/her ATIS line:
Wien Delivery: Report ready for clearance callsign-only
Then it comes down to:
AUA251: Delivery, AUA251 ATC: Austrian 251, Delivery, cleared München SITNI4C, squawk 4600, Info A.
On incomplete or wrong clearance, the wrong part is repeated:
AUA251: Delivery, AUA251 ATC: Austrian 251, Delivery, cleared München SITNI4C, squawk 4600, Info A. AUA251: cleared München SITNI2C, squawk 4600, Info A received. ATC: Austrian 251, confirm SITNI4C. AUA251: SITNI4C, Austrian 251. ATC: Austrian 251, readback correct, contact Ground 121,6.
Flight plan corrections
ATC: Austrian 251, you need an odd flight level, do you request 210 or 230? AUA251: Flight level 210, Austrian 251. ATC: Austrian 251, flight plan amended with flight level 210, cleared Frankfurt SITNI4C, Squawk 4600, info A. AUA251: Flight plan amended Flight level 210, cleared Frankfurt SITNI4C, Squawk 4600, Info A on board.
In some cases, clearances have to be modified due to changing runways or clearance altitudes. Most likely, it is GND or TWR who do this, but still it is a clearance chage:
ATC: Austrian 251, re-cleared SITNI5B runway 34, rest of clearance unchanged. AUA251: re-cleared SITNI5B, Austrian 251.
ATC: Austrian 251, initial clearance altitude 4000ft AUA251: cleared 5000ft, Austrian 251.
