Highland Express is based in Salzburg LOWS and serves Austria, Italy, France, and Switzerland.

If you are looking for some challenging, shorter flights in the mountains in questionable weather, then California Express is looking for you!! High-altitude mountain flying has always been one of the more dangerous activities GA aircraft undertake each year. Winds are usually fairly high at higher altitudes, particularly following a large weather system, The wind then funnels through mountain valleys, spills through the passes' cracks and crevices, and mixes with winds from other valleys and winds coming over the mountains. This can lead to a lot of disturbed air, and some serious turbulence. To make flying more challenging, density altitude must also be factored in. High density altitude leads to decreased aircraft performance, especially during hot summer days. Density altitude is a way of factoring heat, barometric pressure (and, for absolute accuracy, humidity) and elevation to determine an equivalent altitude that, at on an atmospheric standard day, would provide similar conditions. For instance, on a hot summer day, a 5,000 foot elevation could very well cause the aircraft to perform much the same as if it were flying at 8,000 feet.
