¶ 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, Udon 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 Phuket: RNAV and conventional SIDs.
| RNAV SIDs | |||
|---|---|---|---|
| Airway | Waypoint | Runway 12 | Runway 30 |
| R470 (Northbound) | ELNET | 1B | 1D |
| R470 (Southbound), W4, Y21 | POVEX | 1B | 1D |
| W5, Y22 | ANPUS | 1B | 1D |
| W15 (Eastbound) | GULNO | 1B | 1D |
| W15 (Westbound) | ESGIB | 1B | 1D |
| W21 | SURGU | 1B | 1D |
| Y1 | TERCO | 1B | 1D |
Initial Climb for Udon Thani is 11,000 ft.
¶ SID Restriction
Normally, RNAV aircraft flying into Don Mueang International Airport / Suvarnabhumi International Airport or overflying Bangkok VOR will be subject to using an alternative route when VT-D30 Area 1 is active.
When VT-D30 Area 1 is active, the route will be:
| Origin | Destination | Route |
|---|---|---|
| VTUD | VTBD | ANPUS Y22 KKN Y23 KRT Y20 UBLOD DCT ENDUU |
| VTUD | VTBS | ANPUS Y22 KKN Y23 KRT Y20 UBLOD DCT EASTE |
| VTUD | Overfly BKK | ANPUS Y22 KKN Y23 KRT Y20 BKK […] |
When VT-D30 Area 1 is not active, the route will be:
| Origin | Destination | Route |
|---|---|---|
| VTUD | VTBD | TERCO Y1 UBLOD DCT ENDUU |
| VTUD | VTBS | TERCO Y1 UBLOD DCT EASTE |
| VTUD | Overfly BKK | TERCO Y1 UBLOD Y20 BKK […] |
¶ 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.
