¶ 5. ATC POSITION PROCEDURE
Controllers are required to complete the ATIS information and tune to the correct frequency before connecting to the server.
In the event that there are no further upper ATC facilities available, controllers shall instruct pilots to switch to UNICOM on the frequency 122.800 MHz.
¶ 5.1. Chiang Rai Tower
¶ Delivery Phase
Due to the low volume of traffic at Chiang Mai Airport, Chiang Mai Ground will be responsible for handling the delivery clearance for departing aircraft as well as managing ground movement for all aircraft.
- After a Pilot has requested ATC Clearance to destination, Controller shall check, if following information in flight plan are filled correctly:
a. Flight rules
b. Equipment
c. SID and Route
d. Requested Flight Level
e. Destination Aerodrome
f. EET and Endurance - Controller shall give appropriate ATC clearance with following information:
a. Callsign
b. Destination Aerodrome
c. Flight Level
d. SID and Route
e. Initial Climb (11,000 ft)
f. Transponder Code
g. NOTAMs (If Required)
NOTAMs: NOtice To AirMens.
SIDs: Standard Instrument Departures.
STARs: STandard Arrival Routes.

¶ Ground Phase
- If the aircraft is departing:
a. When a Pilot is ready for push back and start up Controller shall give the clearance with the Facing (North, South, East, West depends on parking stand) to the Pilot.
b. After Pilot ready to taxi Controller shall give the following information/clearance to the pilot:
i. QNH
ii. Taxi route depends on runways in use and NOTAMs.
c. Transfer Pilot to Tower frequency on 118.100 MHz - If the aircraft just arrived:
a. Controller shall Issue taxi clearance to Gate, If Pilot doesn’t request any specific Gate Controller could select the random Gate for the aircraft
b. After Parking completed Controller shall release Pilot to switch to UNICOM on 122.800 MHz
The ground controller has the capability to refer to the aerodrome chart to identify and provide the appropriate taxi route for aircraft movements on the ground.
