## Stereo Approaches
Stereo Approaches are the primary procedure for fighter & strike aircraft (e.g. F18, HAWK, PC21) recovering back to airbases after operations in SUA. Aircraft track from specified SUA exit gates where they join the procedure, tracking along charted TACAN arcs/radials which position them for an initial and pitch or instrument approach.

Stereo approaches should generally be used during high military traffic levels and nominated on the appropriate aerodrome ATIS.

Stereo Approach charts can be found in the [RAAF TERMA](https://ais-af.airforce.gov.au/australian-aip){target=new}

## Airspace
### Default
By default, WLM TCU owns the airspace within the WLM MIL CTR `SFC` to `F125`. This may be amended by NOTAM.
WLM TCU owns the airspace within the WLM MIL CTR `SFC` to `F125`.

When WLM TCU is active above `F125` by ad-hoc release or NOTAM, WLM-L_APP owns the airspace `SFC` to `F125`, while WLM APP owns the rest of WLM TCU airspace above `F125`. This may be adjusted as required with coordination.

@alphadelta332 @ST6-Bravo either of you guys know what the upper limit of the WLM TMA is when both positions are online?

It's not particularly well documented in the SOPs at the moment, but I don't believe there is a default. It's just whatever additional airspace is released or RAs activated above F125

Yeah ok. I had a look at work today, there's an airspace segment which extends above the eastern TMA block to FL600 but we don't want FL600 TMAs haha. Maybe we could top it out at say FL245?

It is the responsibility of the WLM TCU controller(s) to negotiate any airspace releases with ARL(All).

### ADC
When WLM ADC is online, they own the airspace within the WLM MIL CTR A (`SFC`-`A050`). This may be amended/released as required between WLM ADC and WLM TCU.

## Stereo Approaches (Fast Jet Aircraft)
Fast jet aircraft typically transit from M550 to YWLM via Gate 6 at `F125`. When requested, or advised via ATIS, the stereo approach may be utilised to facilitate aircraft recovery.

!!! tip
See [Controller Skills](../controller-skills/military.md#stereo-approaches) for more details about stereo approaches.

!!! Example
**MAPL45**: "WLM TCU, RTBing via G6 for RWY12"
**WLM TCU**: "MAPL45, cleared the stereo appraoch for RWY 12 via G6, once 9DME north of the tacan descend not below `A050`"
**MAPL45**: "Once 9DME north, descend not below `A050`"

!!! note
Stereo approach charts are available in the [RAAF TERMA](https://ais-af.airforce.gov.au/australian-aip){target=new}.

## Charts
!!! note
Additional charts to the AIP may be found in the RAAF TERMA document, available towards the bottom of [RAAF AIP page](https://ais-af.airforce.gov.au/australian-aip){target=new}
