¶ Overview
The purpose of the ground controller position is to provide air traffic control services related to aircraft movements on the ground. The ground controller is one of the key positions within the air traffic control system responsible for coordinating and guiding aircraft on the airport surface. Additionaly due to lack of traffic, Chiang Mai Ground will be giving departure clearance.
- Issues departure clearances, including route, altitude, and instructions.
- The position ensures a smooth and efficient flow of departing aircraft.
- Giving taxi instructions to departing and arriving aircraft.
- Giving departure instructions to VFR aircraft if necessary.

¶ SID Assignment
SID assignment in Bangkok FIR is fairly simple. Depending on the route the aircraft is taking, the SID will be chosen to align the aircraft with that route.
There are two types of SIDs at Chiang Mai: RNAV and conventional SIDs.
| RNAV SIDs | |||
|---|---|---|---|
| Airway | Waypoint | Runway 18 | Runway 36 |
| A464 | ENBAT | 2S | 2C / 2N |
| A581 (Northbound) , W20 | ADLUS | 2S | 2N |
| A581 (Southbound) | GOGOP | 2S | 2C / 2N |
| R207 (Northbound) , W36 | LAMUN | 2S / 2W | 2N |
| R207 (Eastbound) , W12 | MONLO | 2S | 2C / 2N |
| W7 | PUMAM | 2S | 2C / 2N |
| W9 (Westbound) | VISES | 2S / 2W | 2N |
| W9 (Southbound) , Y7 | PANTA | 2S | 2C / 2N |
| W15 | KABMU | 2S | 2C / 2N |
| W16 | ASAVI | 2S | 2C / 2N |
| Conventional SIDs | |||
|---|---|---|---|
| Airway | Waypoint | Runway 18 | Runway 36 |
| A464 | KEDOB | 1A | 1B |
| W9 (Eastbound) | PSL (Phitsanulok VOR) | 1A | 1B |
| W9 (Westbound) | MHS (Mae Hong Son VOR) | 1A | 1B |
| W15 | PR (Phrae NDB) | 1A | 1B |
| W16 | UTTAR | 1A | 1B |
| W20 | CTR (Chiang Rai VOR) | 1A | 1B |
Initial Climb for Chiang Mai is 11,000 ft.
¶ Squawk Code
The squawk code for Bangkok FIR are as follows:
| Flight Status | SSR Code |
|---|---|
| International | 0700-0777, 6100-6177 |
| Domestic | 1260-1277, 3301-3377, 4200-4277, 4400-4477, 4500-4577, 7200-7277 |
It is recommended to use the squawk request system in Aurora to prevent duplication of squawk codes.
¶ Special Procedure
The ground controller and tower controller coordinate for the transfer of aircraft control. Ideally, the transfer occurs before the aircraft reaches the holding point for the runway. This promotes smoother traffic flow.
¶ Overview
The purpose of the tower controller position is to provide air traffic control services related to the management of aircraft within the airport's air traffic zone. The tower controller is one of the key positions within the air traffic control system responsible for ensuring the safe and efficient movement of aircraft in the vicinity of the airport.
- Giving take-off and landing clearance to departing and arriving aircraft.
- Giving departure instruction for aircraft.
- Giving traffic information to aircraft to look for traffic.
- Handle VFR aircraft in the airport circuit pattern.
Aerodrome traffic circuit:
Runway 18 by entering left traffic circuit only.
Runway 36 by entering right traffic circuit only.
Overhead approach pattern:
Runway 18 by left turn pattern.
Runway 36 by right turn pattern.
