Britten-Norman BN-2 Islander/Defender
Seeing a need for a simple twin piston aircraft able to operate from short unprepared runways the Britten-Norman Islander was designed in the mid 1960s. In general the aircraft can be easily recognised as it is a high-wing aircraft with engines underneath the wings and a fixed landing gear. The main gear with double wheels is attached to the wings at the engine nacelles, meaning long struts. The nose gear has a single wheel. The wings have a large span and have the same chord and thickness along the span, except for the tips. The fuselage has a rectangular cross section and large windows. It is narrow and access to the seat rows is via large doors on the left and right side. Finally, the tail is of a conventional design.
The different versions of the Britten-Norman BN-2 can be identified by looking at:
- the shape of the engine nacelles
- the size of the wing span
- the shape of the nose
- the presence of droop flaps
- the presence of pylons under the wings (for storage)
Details will follow later.
Confusion possible with
This aircraft family is of similar size as the BN-2 and also has high wings and a conventional tail. The single wheel main gear of the Twin Commander is retractable though, in the nacelles which are thus longer. The wings are more slender, tapering towards the tips. Additionally, the horizontal stabilisers have dihedral. Finally, the cabin windows are smaller.
This is the larger, three engine version of the BN-2 Islander. Its fuselage is longer, as is the nose. The third engine is in the vertical stabiliser. For the rest both aircraft types are very similar.
Vulcanair AP68TP Viator/A-Viator
This aircraft has an all single wheel retractable gear, attached to stubs under the fuselage, and a long nose to house the nose gear. The smaller Partenavia P.68 has a fixed gear, but attached to the fuselage.
This aircraft can be seen as a more modern version of the Islander. The main differences are that the P2012 has the fixed main gear attached to the fuselage and the smaller cabin windows with 'race track' shape. (photo by Marco Papa, used with permission)
