A few days ago Textron Aviation presented the new family of legendary executive turboprops aircraft to the public: the King Air 360 and King Air 360 ER. The historic family of King Air aircraft, was introduced by Beechcraft in the 1960s and since then more than 7600 aircraft have been sold, this record has earned the "King of Air" the world's best-selling twin-engine turboprop executive aircraft.

The first two series of executive turboprops were the Model 90 and Model 100 marketed from 1964 onwards and known as King Airs.

The "major" variants with the "T" tail empennages were the series Model 200 and Model 300, known throughout the world by the name Super King Airs. The prefix "Super" even if abandoned by Beechcraft in 1996 is still used to distinguish the minor series (90 and 100) from the major (200 and 300).

Overview

The King Air 360 and King Air 360 ER are therefore the evolution of the Super King Air family, the latest after King Air 350i. The improvements of this new series mainly impact on situational awareness and comfort of pilot and passengers, they are in fact equipped with the system Solutions & Support (IS&S) ThrustSense Autothrottlea device capable of automatically adjust the power (over-speed, under-speed, over-temp, over-torque control) of the engine in the various phases of flight, reducing the workload, improving situational awareness and decision-making for the pilot.

Another avionic's feature is the digital cabin pressure control that automatically fit the pressure according to climbs and descents. This integration is included in the latest generation of deck Collins Aerospace Pro Line Fusion.

Also improved comfort for passengers who can appreciate the improved internal cabin pressure (5,960 feet in cabin vs 27,000 flight altitude N.A.) that is 10% lower than the predecessor King Air 350i. This improvement makes the flight more pleasant, especially on long distances.

Description

The Beechcraft King Air 360 is a low-wing, twin-engine turboprop company with “T” tail. It has tapered wings equipped with winglets at the ends, an aerodynamic solution that reduces total drag, improving wing efficiency and flight performance.

It is equipped with two turboprop engines Pratt & Whitney PT6A-60A from 1050 SHP and pulled by Hartzell four-blade propellers at constant speed, equipped with auto-feathering and reverse.

It can carry over 9 passengers and has a load capacity of 1,154 kg. Regarding the load, it is possible to place part of the luggage in compartments obtained from the rear cowlings of the two engines (photo).

Avionics

As mentioned above, the King Air 360 is equipped with the integrated flight deck Collins Aerospace Pro Line Fusion with Autothrottle functionality that automatically adjusts engine power during take-off, landing, ascent and descent. This technology significantly reduces the pilot's intervention by preventing the critical conditions of over-speed, under-speed, over-temperature and over-torque. Another important upgrade is the automatic adjustment of the pressure in the cabin based on the various flight altitudes.

The on-board avionics features are as follows:
