### SID Selection
Aircraft planned via **KEXAR**, **LIMLO**, **MONDO**, **UBSON**, shall be assigned the **Procedural SID** that terminates at the appropriate waypoint.
Aircraft who are not planned via those points or who are negative RNAV may be assigned a RADAR SID or a visual departure.

#### Coded Departures (Fast Jets)
Visual Departures are commonly requested by high performance military jets and often processed in the form of a coded departure (e.g. CLASSIC1 departure), which can be found in the AD2 Sups Page for YWLM. These coded departures provide a corridor with altitude constraints to join the Military Training Areas east and west of Williamtown, avoiding civilian traffic inbound to Sydney.

| Tracking Gate | Departure | Initial Constraint | Route |
| ----- | ---------| --------------- | ------------------------ |
| G1-G2 | PEPPER 1 | `A080` at ERVEV | ERVEV G1/G2 (Transition)
| G3-G7 | CLASSIC 1| `F125` at G3-G7 |
| G9 | RADAR | 'F125' at G9 |
| UKDIP | CLASSIC 1| 'A090' at UKDIP |
| OLVEP | CLASSIC 1| 'F130' at OLVEP |

!!! note
ACFT Departing RWY 12 for G3-7 are required to avoid SAWR on the Classic 1.
ACFT Departing on Classic 1 will be issued a direction of turn during take off clearance, preferablly to the south in order not to impede on the SAWR boundries on the departure.

Is there any guidance on how these aircraft should track to avoid the weapons range?

Typically either climb quickly up to F130 or depart to the south.


!!! example
WGTL21 plans to enter M550 via Gate 4 for Military Training.
**WLM ADC**: "WGTL21, cleared to YWLM via Gate 4, flight planned route. Runway 12, Classic 1 Departure. Climb to `F125`. Squawk 5001, Departure Frequency 133.300"

Is it likely that aircraft would file Gate 4 in their flight plan, or is it an ATC responsibility to amend their flight plan via the most appropriate gate?

Typically, we file M550 and assume ATC gives us Gate 4.

I put in a note saying Gate 4 is the most common if that helps @mattkelly4

In that case, we'll need guidance for controllers to be able to make these sorts of decisions. We have to assume the controller reading this content has no knowledge of the local operations (because they likely don't)


!!! example
MAPL03 was assiged the CLASSIC 1 departure with their initial clearance.
**WLM ADC**: "MAPL03, make left turn, reach `F125` by Gate 3 , cleared for takeoff"
**MAPL03**: "Make left turn, reach `F125` by Gate 3, cleared for takeoff, MAPL03"

!!! note
Since the Coded Departures are not SIDs, WLM ACD needs to write the name of the coded departure in the Global Ops Field of the FDR and amend the flight plan route to include all relevant tracking points.

### Gates for the SUA
There are 8 gates to facilitate departures and arrivals into these Training Airspace, based on the WLM Tacan.
WLM Eastern Airspace
G1 029/25
G2 050/25
G3 068/25 (Lighting Corrider Entry)
G4 088/25
G5 105/25
G6 125/25
G7 135/25
G9 007/25
WLM Western Airspace
UKDIP 311/25 (Thunder Corridor Entry)
SAWR (Salt Ash Weapons Range)
OLVEP 033/10

I'm assuming that G1 029/25 means Gate 1 which is bearing 029 at 25nm? Is there any chance we could get a diagram showing these positions?

Yeah, there is one in the ad2 sup, that I could modify into vatsys.


### Initial and Pitch Procedures
The Intial Points for RWY 12 is the SW tip of Grahamstown Dam, and RWY 30 is the coastline.
