Bacchus Marsh Airfield is located south〔 of Bacchus Marsh, Victoria, Australia. The airfield is owned by the Shire of Moorabool,〔http://www.moorabool.com.au/invest/road〕 but is operated by the Bacchus Marsh Airfield Management (BMAM).〔 BMAM comprises representatives of the shire, the three resident gliding clubs (the Geelong Gliding Club,〔(Geelong Gliding Club )〕 Victorian Motorless Flight Group〔(Victorian Motorless Flight Group )〕 and the Beaufort Gliding Club〔(Beaufort Gliding Club )〕), and the Tarago Valley School of Aviation〔(Tarago Valley School of Aviation )〕 (a power flying school). The airfield with an elevation of above sea level, consists of two sealed cross strips with wide grass verges on either side (alignments 01/19 , and 09/27 ).〔 The gliding clubs conduct a combined operation launching from the grass verges while the power school operates concurrently from the sealed strips ==Gliding== The site offers a variety of soaring conditions. Thermal conditions enable soaring for most of the year, and are sufficiently reliable to enable cross country flying from September to April. Late in the afternoon though, lift can be damped with sea breeze fronts moving in from the south east. The higher terrain to the north and north west can lead to the development of wave and ridge lift especially during the winter months. Frontal lift is also frequently seen at the site. The airfield is located in the rolling volcanic plains of western Victoria. The topography to the east and south consists of flat farming land extending to Port Phillip Bay and Bass Strait respectively. To the north the terrain dips initially into the Werribee River valley, with the Bacchus Marsh township, before rising to the Blackwood Ranges; the foothills to the Great Dividing Range. To the west the land is used mainly for agricultural purposes. An escarpment; the Brisbane Ranges, results in the terrain altitude increasing abruptly by , but is quite suitable for cross country flying at all skill levels. Due to the proximity to Melbourne, soaring at the site operates under a restricted ceiling of above sea level immediately above the site, however this ceiling steps to a few kilometres to the west and progressively thereafter to . To the south the ceiling again steps up progressively. Operations to the east are limited by the decreasing height of the ceiling, and to the north by a combination of the mountain ranges and air traffic ceilings.〔(Geelong Gliding Club - Members Site )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bacchus Marsh Airfield」の詳細全文を読む スポンサード リンク
