Cessna 172  “Hawk XP”  

Seaplane and amphibian

The aircraft is usable by all Club's members.


The Cessna 172 XP (R172K) represents the evolution of the 172 and is used in amphibious mode in order to allow students to carry out the land part of the training for their license, as well as for members to transfer or stop over at airports.

It is equipped with a 6 cylinder continental IO-360KB engine, that gives 195HP at 2400 RPM.

The floats are Wipline 2350 amphibious, and the aircraft is also equipped with EDO 2440 streight floats.

  An amphibious 172

Ideal for the final parts of training, it's the best amphibious aircraft in the four-cylinder class


Most lessons to achieve the pilot license are carried out in a Cessna 172 seaplane, an ideal aircraft for discovery, towards the end of the course; in the navigation section you need an amphibious aircraft. You can in fact complete the navigation in a seaplane, however it is very true that the pupil should learn the airport procedures and the many procedures of this complex environment.
    An amphibious aircraft for training, should be as similar as possible to the training aircraft used in earlier stages in order to avoid the students having to familiarise themselves with a new aircraft at this delicate stage of training. Here explaining why the Cessna 172 XP amphibious is the ideal aircraft, as the transition from the regular 172 is made with minimal problems.

The acquisition of the I-DROV was a laborious process, after having found an excellent example, with only 280 hours of flight; we attached the floats (amphib wipline 2350, which was a tough task. The aircraft then possessed two types of floats, but it is mainly used as an amphibious aircraft.

To outline all that is different from a 172, the XP has a variable pitch propeller with the relevant controls and a pressure gauge that shows pressure and flow.
In addition the aircraft has six cylinders that makes the control of the engine temperature a bit sensitive. The engine flaps are always visible are usually left open during basic operations. The rudder trim is also a new feature on the XP.
    The performance of the XP is excellent, it consumes 10 gallons per hour, has good clime rates and cruise speed, more or less 100 knots. The shape of the float hull is V shaped meaning less stress from the waves when landing. The variable pitch propeller comes in useful when climbing on the step.

There isn't much to say about piloting, other than the necessity to be careful not to overheat and overcool the engine too suddenly.
As for all amphibious aircraft with floats, the weak point is the payload.

Another thing to remember for the XP is to not make the critical error of fully extending the landing gear when landing on water. The audio warning for the position of the landing gear is very useful, but the check should also be carefully made.
