ATC COMMUNICATIONS

1. BASIC ATC
COMMUNICATION
C104 / Israel Reyes

2. ATC COMMUNICATION
Many new pilots are afraid to pick-up
the radio and say hello. In this lesson we will
prepare you to do just that. The positions air
traffic controllers staff don’t change; only the
voices do.
In the next few slides, we will review each
position and the basics behind communication.
To be fair, there is no one way to speak with
ATC. Each controller has his or her own style.
However they will all need the same basic
information that we will cover here.

3. ATC COMMUNICATION
THE ATC POSITIONS
• DEL = Clearance Delivery – Get your route
• GND = Ground – Get taxi to/from Runway
• TWR = Tower – Get take-off/landing clearance
• DEP = Departure – Vectors / Climb
Instructions
• APP = Approach – Vectors / Arrival
Instructions
• CTR = Center – Monitors / Re-Routes as
needed

4. Clearance Delivery (DEL)
DEL is the first position you will speak to when you are park at a
gate. DEL controller is responsible for checking your field flight plan.
They will make amendments as needed and inform you of any
changes made. They will also give you the specific details related to
your departure clearance. Lets look at two basic examples. Radar
Vectors and RNAV clearances. In this example you are AAL2387.
Kennedy Clearance Delivery, American 2387, request IFR to Miami as filed.
American 2387, Kennedy Clearance Delivery, Cleared to Miami International Airport via the Kennedy 3
Departure, radar vectors to WHITE than as filed. Climb and maintain 5000. Expect FL280 10min after
departure. Departure will be on 132.7. Squawk 0507.
Cleared to Miami via the Kennedy3 Dep. Initial 5000, expect 280 10after dep. Dep on 132.7 Squawk 0507
for AAL2387.
NWK_DEL, AAL2387, request IFR to Miami with information Alpha.
AAL2387, NWK_DEL, Cleared to KMIA via the PORTT3 DEP. Climb via SID top altitude 5000. Expect FL280
10min after dep. DEP_FRQ 132.7. Squawk 2371.
2371 AAL2387.
Its is important to know, that clearances can be amended for any number of reasons. Some can
include, weather, incorrect SID filed, invalid exit gates, incorrect altitudes and so on. Your
instructor will review some examples with you.

5. Ground - GND
The ground controller is tasked with all movement areas
on the airport located between the ramp area and runways.
Each airport is very different and require your understanding
of the airport diagram.
Example 1 – KJFK
http://155.178.201.160/d-tpp/1705/00610AD.PDF
Example 2 – KMIA
http://155.178.201.160/d-tpp/1705/00257AD.PDF
Your instructor will use the provided diagrams to
illustrate a number of different taxi instructions.

8. Tower - TWR
The tower controller, will issue you take-off and landing
clearance. They will also provide you with a wind check and initial
vectors if not departing RNAV. The tower will also provide you with an
initial traffic advisory if it’s needed.
JFK_TWR, AAL2387, Short of 4L ready to go.
AAL2387, JFK_TWR, wind 045@7, runway 4L cleared for take-off.
Cleared for take-off, AAL2387.
NWK_TWR, AAL2387, Short of 4L ready to go.
AAL2387, NWK_TWR, on dep fly heading 060, wind 048@8, runway
4L cleared for take-off.
Cleared for take-off, 060 on dep, AAL2387.
Again, different variations are possible depending on the
airport you are departing. Speak with your instructor for more
examples.

9. Departure - DEP
Departure controllers get you from the initial
climb to the start of your en-route stage.
NY_NWK_DEP, AAL2387, climbing 1.5 for 5.
AAL2387, NY_NWK_DEP, radar contact turn
right heading 110 climb and maintain 7000.
110 and up to 7 for AAL2387.
AAL2387, contact NY_CTR on 132.05.
Over to CTR on 132.05, thanks, AAL2387.

10. Center - CTR
The center controller, gets you to your cruise level and monitors
your flight progress. Center will continue to hand you off center to
center until you commence your approach into your destination.
NY_CTR, AAL2387, with you 7000.
AAL2387, NY_CTR, radar contact, proceed direct MERIT, climb and
maintain FL210.
Direct, Merit up to FL210, AAL2387.
AAL2387, Contact Boston Center on 134.5.
Over to 134.5, thanks for your service.
Boston Center, AAL2387, with you climbing 15000 for FL210.
AAL2387, Boston_CTR, radar contact, 24miles from Bradley VOR,
Welcome Aboard
And so on, until reaching your approach area.

11. Approach – APP
The approach controller is tasked with guiding you to your terminal airspace.
There job is to position you to shoot the approach.
REG_APP, AAL2387, with you, descending via the WHINY4 arrival.
AAL2387, REG_APP, cross HILLZZ @ 6000 expect ILS RNW 18R approach,
DFW alt 2992.
HILLZZ@6000, expect ILS18R approach, AAL2387.
(**you may receive vectors to final or follow RNAV instructions as
needed**)
AAL2387, you are 8 miles from YOHAN, descend and maintain 2000 until
established. Cleared ILS RNW 18R Approach.
Descend and maintain 2000 until established, Cleared ILS RNW18R APP, AAL2387.
AAL2387, Contact DFW_TWR on 134.3.
Over to tower, AAL2387, See Ya!
Again, many different things can happen here. The instructions can be split
or given all at one time. Speak with your instructor for more examples.

12. Tower - TWR
We are now back with tower. Like before towers job, is to
provide you with a wind check, traffic and wake turbulence advisories
as need and finally clear you to land at the airport.
DFW_TWR, AAL2387, established ILS 18R.
AAL2387, DFW_TWR, wind 170@15, RNW 18R Cleared to land.
Cleared to land, AAL2387.
DFW_TWR, AAL2387, with you 18R to land.
AAL2387, DFW_TWR, wind 170@15, #2 behind company 777 on 4
mile final, caution wake-turbulence, RNW18R, Cleared to Land.
Cleared to land, #2 behind the company heavy, AAL2387.
Once more, depending on the situation, multiple factors can
change your clearance or cause you to go around. Speak with
your instructor for more examples.

13. NOTE
This is a good time to give you some differences from real world flying
and VATSIM flying. In the real world, you will always have an air traffic
controller to assist you. In VATSIM this may NOT always be the case. You
might find your self departing JFK without speaking to anyone. This is due
to individual availability.
To solve this, VATSIM has implemented a top down control system. What
does this mean to you.
You might find yourself speaking to NY_CTR for an IFR clearance instead
of JFK_DEL. To further this, if no controller is online, you are authorized to
depart any field on unicom freq 122.800. This is a text only freq. It is a
way to allow pilot coordination when no controller is available.
Note that if a controller comes online, they will send you a contact
request, you MUST contact the controller within a reasonable time. DO
NOT ignore the request. It can cause you to be flagged by that controller
and a VATSIM supervisor may disconnect you and even suspend your
account.

When your ground controller is a DEP controller or above it
is a good curtsey to inform them when you are parked. This is
because most of them, have multiple airports under their control
at one time.
