4. Controlling traffic
This part is an illustrative guide about how you control an aircraft from the time you take over control until you hand it off to someone else. The guide is divided into two parts, Controlling departures and Controlling arrivals, since it differs some. First letīs see how to control aircrafts coming into your sector.
4.1 Controlling departures
There is no traffic under our control but, as you can see in the image above, a flightstrip has appeared and, as the color grey indicates, we have not yet accepted the handoff from tower. Just above the ATC-Comm field you can see a transmission sent to you from Tower asking you to accept handoff.
When clicking the grey flightstrip you inform tower that you accept the handoff. As you can see in the image above there is also a transmission sent to tower accepting handoff for KFB480.
The aircraft will check in with you after takeoff and then youīre in control. Let us command the aircraft to climb to FL120 and fly direct Nortel. This is easy, just issue the appropriate commands either using voice or text. The text command can look like this: "480 CM 120 PD NTL" (CM - Climb and maintain, PD - Proceed direct)
KFB480 is making a steady climb towards Nortel and, as the image above indicates, he has passed FL100 so we can initiate a handoff to the next controller by entering +802. The + indicates ATC to ATC communication and 802 is the aircraft datacode (which can be found either on the flightstrip or on the aircraft datatag).
While waiting for the next controller to accept, the flightinfo turns red. When an R comes up you can hand it over to the next controller by typing "480 CC" (CC - Contact Control). The controller will also accept the handoff by sending you a message through the ATC-Comm module.
After you handed the aircraft over it turns green. By pressing +802 again the datatag will disappear and you will only see the echo.
And there you have it, a successful handling of a departing aircraft! Now letīs take a look at how to guide an arriving aircraft safely to its destination.
4.2 Controlling arrivals
Time to handle some arriving traffic. Our first arrival has appeared as seen in the image above, itīs Scandinavian 904 from Newark, New York. Accept the arrival by entering +141 in the ATC-Comm field.
After accepting the aircraft turns magenta and checks in. Letīs clear it down to FL70 and give him heading 090 since there isnīt any other traffic in the area. Using textcommand: "904 DM 70 FH 090" (DM - Descend and maintain, FH - Fly Heading. You can also use TL - Turn Left heading 090).
After an additional command earlier, clearing SAS904 to altitude 2500ft, heīs now on the downwind leg for rwy 26 which is our selected landing runway.
Letīs clear him for approach: "904 FH 230 CI 26" (CI - Cleared Instrument approach rwy 26).
SAS904 is turning onto the localizer centerline, looks good. Initiate handoff to tower by entering +141 in the ATC-Comm field.
Tower accepted the aircraft. Letīs ask the pilot to contact tower now: "904 CT 118.5" (CT 118.5 - Contact Tower on 118 decimal 5)
SAS904 is now under tower-control expecting to land shortly, and that means our work is done.
