Takeoff description
PG/HG - ASL: 565m (HG can use take-off ramp at ASL of 850m) Lijak is one of the most favorite take-off places in Slovenia. Its special location offers an extraordinary number of flying days throughout the year. There are very good weather conditions for flight also during winter time; even when in the nearby Vipava valley blows strong bora, Lijak is quite well protected. Also, in the winter time the cloud base can be higher than in summer. This geat take-off place is situated above a karstic spring of the brook Lijak, on a sharp edge of the Trnovo landscape rising over the characteristic, funnel-shaped steep slope – hence the name; Lijak is a Slovenian word for funnel.

Max 750m/AGL; North of TO: max 2900msl; over LZ: max 300m/AGL. AVOID flying LOW over ridge to the East during Bird nesting season. PLEASE USE LANDING STANDART APRPROCH!
