Radio check

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.)

Standard clearance

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.

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.

Incomplete/wrong readback

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.

Clearance modifications

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.

(This section is not finished yet!)

Now one Example for normal Clearence. You will learn in detail in the next section. Situation: Austrian 251 is Requesting clearance to München, Gate C34, Fokker 70, Info C on board.

AUA251: Good Day Wien Delivery, Austrian 251 Info C on board, Gate C34, requesting clearence to München.
LOWW_DEL Austrian 251, cleared to München via SITNI4C, initial climb 5000 ft, Squawk 4612, info C correct.
AUA251: Cleared to München, Sitni4C, Squawk 4612, AUA251.

Handover/Handoff: At some point, it's time to say good bye - that is handoff or handover. It is vital that no aircraft disappears from the radio. Handover is transfer to another station. Handoff is dropping contact into uncontrolled airspace (like UNICOM).

LOWW_DEL Austrian 251, readback correct, for push and start contact Wien Ground (LOWW_GND) 119.4, Bye Bye.
AUA251: Contacting Ground 119,4, bye!
