Diamond DA42 Twin Star

The Twin Star is an advanced four seater aircraft with a composite airframe, twin turbo diesel engines, and glass panel cockpit. It is fully IFR capable and equipped with known ice protection.

The DA42 features simple operation, smooth and quiet powerplants, and incredible range, consuming only 8.8 gallons of JetA per hour at 60% power setting. The wingspan of 13.4 m. (44 ft) provides maximum separation of wing tip magnetometers to 16.2 m. The DA42 can fly low and slow with a minimum survey speed of 90 kts and survey sorties of over 6 hours.

Recently a 3 foot nose stinger was added to house a Totem-2A VLF-EM receiver.

Our DA42 is operated by the Diamond Flight Centre London Inc., who look after the maintenance on the aircraft and supply us with experienced survey pilots.
