This is the larger, land-based version of the P136 amphibian, with two piston or turboprop engines driving pusher propellers mounted on top of the gull wings. These wings go through the fuselage, somewhat above the middle of its cross section. Tip tanks are standard.
When you hear an Avanti in approach or take-off you will immediately recognise its distinctive sound. In appearance, it is also unlike any other aircraft. Like the Beech Starship it has a canard wing configuration with pusher props, but the wing is attached right through the middle of the fuselage and the engines are in the wing. Moreover, the aircraft has a T-tail.
This quite typical bizjet type is the result of an adventure between Piaggio and Douglas. You can easily recognise the PD808 from the front as the engines look as if they are “glued” directly against the fuselage, instead of being placed on pylons. Also note the long dorsal fin and the slightly "popped-out" cockpit.
The P-3 was the horizontally opposed piston powered predecessor of the PC-7. Both have similar lines, except for the wider nose. The P-3 has bubble canopy with three frames.
As the only single engine turboprop with low wings and a T-tail the Pilatus PC-12 was easy to recognise, until the arrival of the similar looking Beechcraft Denali. The main differences are in the tail area: the PC-12 has a bullet fairing on top of the vertical fin, a large dorsal fin and ventral fins.
The Pilatus PC-21 is a further development of the PC-7 and PC-9. It has a higher fuselage than both predecessors and a shark-like vertical stabiliser. Also the nose with prop spinner looks like that of a shark, more than on the PC-7 and PC-9.
Being very similar in appearance you could easily mistake the PC-24 for a Learjet 45 or Cessna Citation CJ4. However the Pilatus has no winglets (compared to the Learjet), a typical dorsal fin (compared to the Citation CJ4) and a large cargo door on the left side, between the wing and engine.
The PC-6 is a single engine, high wing, tail wheel aircraft with a characteristic non-swept vertical tail and uniquely shaped cabin windows: they look like two parts of an oval. It comes with many different engines, piston and turbine.
The Pilatus PC-7 was one of the first turboprop powered training aircraft, and the starting point of a whole family of Pilatus turboprop trainers, like the PC-9 and PC-21. Other manufacturers have since developed similar aircraft. The basic PC-7 is recognised best by the large, nearly single piece canopy.
The Pilatus PC-9 is a developement of the PC-7, with as main external change the two-piece canopy with the back seat placed higher than the front seat. The wings have no dihedral close to the fuselage; only the outer wings have dihedral.
