The aircraft used for intra continental operations are ski-equipped DHC-6 Twin Otter aircraft.

The Twin Otter aircraft is a twin engine turboprop, fixed undercarriage STOL (Short Take Off and Landing) aircraft with a side entry cargo door.

Its configuration makes the Twin Otter suitable for general Antarctic operations, while the payload/range characteristics make it suitable for the long distances between our Antarctic stations.

A crew of two pilots and one engineer operate and maintain the Twin Otter aircraft which is owned and operated by contracted service providers Kenn Borek Air.
