Cessna U206
The original 1964 model was the U206, powered by a 285 hp (213 kW) [Vous devez être inscrit et connecté pour voir ce lien].
The “U” designation indicated “utility” and this model was equipped with a pilot side door and large clamshell rear door serving the back two rows of seats, allowing easy loading of over-sized cargo.
There was a TU206 turbocharged version powered by the [Vous devez être inscrit et connecté pour voir ce lien] engine producing 285 hp (213 kW).
After 1967 the turbo TU206 was powered by a TSIO-520-F of 300 hp (220 kW) (the extra 15 hp (11 kW) were
obtained by turning the engine at a higher rpm, and was only allowed for five minutes.
Due to the large propeller diameter, the additional engine speed meant that the propeller tips were pushed to transonic speeds, which required much more power.
Thus the extra 15 hp (11 kW) did not produce much performance improvement but did produce unpleasant noise levels.

Re: Cessna 206
From 1964 to 1969 the U206 was known as the “Super Skywagon”.
From 1970 it was named the “Stationair”, a contraction of “Station Wagon of the Air”, which is a good description of the aircraft's intended role.
Sub-variants were designated U206 to U206G.
In 1977 the U206 had its engine upgraded to a Continental IO-520-F of 300 hp (220 kW) (continuous rating, obtained at a lower speed than the previous IO-520-F) and the TU206 powerplant was changed to the TSIO-520-M producing 310 hp (230 kW).
Production of all versions of the U206 was halted in 1986 when Cessna stopped manufacturing all piston engine aircraft.
A total of 5208 U206s had been produced.

Cessna P206
1965 saw the P206 added to the line. In this case the “P” stood for “people”, as the P206 had passenger doors similar to the Cessna 210, from which it was derived, on both sides.
The P206 was produced from 1965 to 1970 and was powered by a Continental IO-520-A of 285 hp (213 kW).
There was a turbocharged model designated TP206 which was powered by a Continental TSIO-520-A also of 285 hp (213 kW).
647 P206s were produced under the name “Super Skylane” which made it sound like a version of the [Vous devez être inscrit et connecté pour voir ce lien], which it was not. Sub-variants were designated P206 to P206E.[Vous devez être inscrit et connecté pour voir ce lien]

Cessna 206H
After a production hiatus of twelve years, Cessna started manufacturing a new version of the venerable 206 in 1998, with the introduction of the newly certified 206H.
The “H” model is generally similar to the previous U206 configuration, with a pilot entry door and a rear double clamshell door for access to the middle and back seats.
The "H" is marketed under the name "Stationair".
The 206H is powered by a [Vous devez être inscrit et connecté pour voir ce lien] powerplant producing 300 hp (220 kW). The turbocharged T206H is powered by a [Vous devez être inscrit et connecté pour voir ce lien] engine of 310 hp (230 kW).[Vous devez être inscrit et connecté pour voir ce lien]
Even though the Cessna 206H is certified as a six seat aircraft in its country of origin, the Canadian aviation regulator, [Vous devez être inscrit et connecté pour voir ce lien] has only certified it to carry five people in [Vous devez être inscrit et connecté pour voir ce lien].
This is due to concerns about passenger egress through the rear clamshell door with the flaps extended.
Cessna addressed one part of this problem early on, after a flight-test aircraft was damaged when the pilot extended the flaps while taxiing, and his passenger had the clamshell door open (for ventilation; it was a hot summer day).

Re: Cessna 206
A switch was added to the flap actuation circuit which disabled the flaps when the doors were open.
The other part of the problem is that if the flaps are already down, the passenger must perform the complicated
procedure of opening the front part as far as possible (about 2 in (5.1 cm)) then open the rear door and restow the rear door handle.
This then gives enough clearance to open the rear part of the door.
Both the 206H and the T206H remain in production in 2008.
By the end of 2004 Cessna had produced 221 206Hs and 505 T206Hs, for a total production of 726 "H" models.
Cessna has indicated that they do not intend to produce a P206-configuration aircraft in the future, due to lack of market demand.

Cessna 207
The Model 207 was a seven and later eight seat development of the 206, achieved by stretching the design further to allow space for more seats.
The nose section was extended 18" by adding a constant-section nose baggage compartment between the passenger compartment and the engine firewall; the aft section was extended by 44" by inserting a constant-area section in the fuselage area just aft of the aft wing attach point.
Thus the propeller's ground clearance was unaffected by the change (the nosewheel had moved forward the same distance as the propeller), but the tail moved aft relative to the mainwheel position, which made landing (without striking the tailskid on the runway) a greater challenge.
The move gave that airplane a larger turning radius, since the distance between mainwheels and nosewheel increased by 18 inches (460 mm) but the nosewheel's maximum allowed deflection was not increased.

Re: Cessna 206
The 207 was introduced as a 1969 model featuring a Continental IO-520-F engine of 300 hp (220 kW).
A turbocharged version was equipped with a TSIO-520-G of the same output.
At the beginning of production the model was called a Cessna 207 “Skywagon”, but in 1977 the name was changed to “Stationair 7”.
1977 also saw a change in engine on the turbocharged version to a Continental TSIO-520-M producing 310 hp (230 kW) – the same engine used in the TU206 of the same vintage.
The 207 added a seat in 1980 and was then known as the “Stationair 8”. Production of the 207 was completed in 1984, just two years before U206 production halted.
A total of 626 Cessna 207s were manufactured.
The Cessna Model 207 has been popular with air taxi companies, particularly on short runs where its full seating capacity could be used.
Very few of these aircraft have seen private use.
