Mt. Dandenong launch is a technically demanding take off with one of the most spectacular views in Victoria. It is an inland site, closest to Melbourne, with both excellent thermal activity but also under the influence of the SW sea breeze in Summer.
ATTENTION: Prior to flying Mt Dandenong all pilots must obtain a site induction from a PG5 pilot (or above) who has flown the site previously. The Site Induction document must be signed and initialed by the pilot receiving the endorsement, and signed by the pilot giving the endorsement. The Site Induction document should be emailed to web@skyhighparagliding.org.au prior to the flight. An onsite induction must also be provided.

| Conditions | For launching purposes, the ideal wind direction is WSW-WNW. SW and NW possible in light to moderate winds. Best wind conditions are W wind, 2-10 Kn. In nil wind thermal cycles should provide the minimal airflow needed for a safe launching sequence. The recommended take off techniques are either the Cobra launch (in strong conditions) or the reverse launch. If using the reverse launch the pilot needs to be standing on the foot path with the glider laid out over the ramp. Pilots flying this site should be highly skilled and well versed in launching from small technical inland launches. |

| Options | Description |
|---|---|
| Pavitt Lane Paddock |

| Liverpool Rd Retarding Basin paddock |
|
| Sheffield Rd bomb out |
|
| Emergency Options | Although there are many other PG viable paddocks within closer glide, we do not have permission to land in these paddocks. Also, the vast majority of these properties are occupied by horses, which are VERY EASILY spooked by PG & HGs. Landing anywhere except the official landing or bomb-out zones will jeopardise this site. |

| Risks | Explanations | Mitigation strategies |
|---|---|---|
| Lines snagging | When launching from standing on the Kyeema Track, the lines can easily get caught on the ground on either side of the ramp. | Roll out the astro turf either side of the ramp and pay close attention to the placement of lines on the ground. The astro turf must be rolled up after launching. |
| Aborting launch once committed | The presence of large boulders beneath Kyeema Track make aborting launch once committed extremely challenging. | Before committing to the launch run, make sure the wing is in the appropriate configuration above your head and is positively inflated. Do not attempt to launch in nil wind. |
| Misjudging wind strength and direction on launch. | Due the the launch being below the top of the ridge and a tree slot launch, wind on launch is significantly less than in the air. Thermals which cycle up the face can make the wind direction appear straighter than the prevailing wind or even overcome an easterly influence. This is a problem as if the pilot encounters a strong SW wing after launch, it may not be possible to make the landing fields. Launching into the lee can see the pilot encounter rotor. Launching in moderate cross wind can also create significant mechanical turbulence after launch. | Verify surface wind speed before launching. The most relevant weather observation stations are Scoresby, Coldstream and Ferny Creek. Expect wind speed of double of what you experience on launch. Use advanced observations techniques to identify local wind strength (refer to onsite briefing induction). |
| Thermals triggering from launch | The launch is one of the most significant trigger sources in the surrounding areas. Launching in a cycle which triggers from launch can see the pilot encounter large sink and turbulence after launch which can make it difficult to clear the trees on launch. | Only launch when a significant cycle passing through the trees below launch or in the presence of sufficient wind. |
| Mechanical turbulence from surrounding trees | The trees surrounding launch create mechanical turbulence. This is particularly prevalent in cross winds or stronger conditions. | Maintain active canopy control after launching. Do not sit until you are clear of the trees. Never release your hands from the controls. |
| Overdevelopment behind launch | It is possible for the day to overdevelop (OD) behind launch, without the being able to observe this development until in the air. Gust fronts from OD were observed in the evaluation flights. | On days when OD is forecast or possible, closely monitor the sky for OD. Closely monitor rain radar for precipitin in the mountains behind launch. |
| General public | Due to launching from (or over) Kyeema Track, the public must be managed for a safe launch. | If another person is not available to help manage the public’s movement during launch, inform the nearby public of your intentions and expected time frame. Give way to pedestrians and cyclists on the track if they have not stopped before commencing your launch. |
| Risks | Explanations | Mitigation strategies |
|---|---|---|
| Maintaining glide to landing options | In a strong SW wind or from below hill height, it may not be possible to reach the landing options. | In sinky air, at altitude below launch, and in SW cross wind, the flight plan is to turn left and fly towards the landing. If the wind is cross from the SW the pilot should immediately turn left after launching unless the pilot is launching into lift. |
| Incoming sea breeze | TheIn the afternoons it is common for the sea breeze to reach Mt Dandenong, changing the direction to SW and increasing the wind speed. If not closely monitored this has the potential to complicate the glide to the landing options. | Constantly evaluate penetration and confirm you have suitable glide to the landing. If you suspect a sea breeze in the near future, move away from the hill towards the landing paddocks. |
| Thermal drift towards the towers | Directly behind launch there are three telecommunication towers. In moderate westerly winds, thermal drift will take pilots towards the towers. | Be prepared to leave the thermal to maintain the required distance from the towers. |
| Risks | Explanations | Mitigation strategies |
|---|---|---|
| Mechanical turbulence in Pavitt Lane | The presence of high trees around the narrow landing field in Pavitt Lane generates mechanical turbulence. | Actively pilot the glider and anticipate the mechanical turbulence. Avoid making low turns. |
