Typical for the Hawk are the small, bean-shaped air intakes in front of the wing roots and the curved leading edge of the vertical stabiliser. Additionally it has horizontal stabilisers with significant anhedral.
British Aerospace Jetstream 41
The Jetstream 41 is the stretched version of the Jetstream 31, so the two aircraft have a large similarity. Apart from the length, the main differences are in the main landing gear, engine nacelles and ventral fin.
Britten-Norman BN-2 Islander
In general the Britten-Norman Islander can be easily recognised as it is a high-wing aircraft with engines underneath the wings and a fixed landing gear. The main gear is attached to the wings at the engine nacelles, meaning long struts.
Britten-Norman BN-2A MkIII Trislander
The Trislander is the three engined version of the BN-2 Islander. The third engine is located in the tail, making it easy to recognise. For the rest is looks like a larger Islander.
This amphibian aircraft was specifically designed as a fire fighter, being able to scoop up water from lakes, rivers and seas. The fuselage cross section is nearly square, ending in a flat tail cone. The cruciform tail is also a trademark of the aircraft.
Canadair CL-41 Tutor
For nearly four decades the Tutor was Canada's primary jet training aircraft. Characteristic for the aircraft are the side-by-side cockpit, small air intakes in the wing roots and a relatively small T-tail.
Canadair CP-107 Argus
This maritime patrol aircraft is based on the Bristol Britannia, visible in the tail and wings, but has a different fuselage including cockpit windows, bomb bays, chin-mounted radom, etc. Als the Argus has radial piston engines.
The Canadair Regional Jet series are essentially a stretched version of the Challenger 600 series. Later versions are more similar in appearance to the Global series, but have engine nacelles with a separate fan exhaust.
CASA 101 Aviojet
The CASA Aviojet has long, oval shaped air intakes in front of the wings. Also characteristic is the exhaust before the end of the fuselage, below the horizontal stabiliser.
CASA C207 Azor
Spanish transport aircraft eithout very specific features to recognise it, or it could be the DC-4 like nose gear, including doors. Just look at the details of cockpit/cabin windows, nacelles and tail to distinguish it from similar aircraft like the Martin 202/404 and Convair propliners.
