Surrounded by bird sanctuaries, holiday spots and areas of outstanding natural beauty, Luftverkehr Friesland (LFH) of Harle, Germany has taken measures to reduce the noise footprint of its three Islander aircraft.\rThe company flies scheduled missions to the Frisian Islands. The nearest and most popular of the islands is only five minutes from Harle airport, and consequently the Islanders can only reach up to 1,000 feet. LFH make up to fifty flights per day in the summer. Jan Brunzema of LFH explained: "A few years ago we decided to buy an Islander with a three bladed propeller direct from the manufacturer. However, the tip speed is the same as on a two bladed propeller. We found a German company called MT Propellers who made slimmer blades and put a fourth blade on. It was essential that the aircraft kept the same performance as we land on short runways."\rLFH's modified aircraft were certified by the GAA last summer, and reports no problems with its four bladed Islander, and plans to convert its other two Islanders to this format when their overhaul is due. The company is organising a meeting at Harle in the new year, and says it is courting interest from Europe, the US and Ecuador.
