Flying the Cessna Citations and Beechcraft King Air 350

A year of charter and corporate flying in the Cessna Citation Encore, Citation II, Citation Mustang. Citation Excel and the beechcraft King Air 350. This is a representative video of a year of flying with cockpit views of takeoffs and landings.

Beechcraft King Air 350 Cockpit View of Night Landing

The cockpit view of a King Air 350 Night landing and flight over south St. Louis. Half way through the video we pass over a house fire. In the cockpit you can see the night lighting of the instrument panel and in the center of the panel is a Garmin GNS 530W combined GPS,Nav, Comm integrated avionics unit . The Garmin is great for situational awareness. It gives the pilot a map view with his course and weather super imposed on top as well as your normal navigation and communications functions

the Beechcraft Super King Air 350

The Beechcraft Super King Air 350 is a commuter category part 23 certified twin turboprop capable of carrying 8 to 12 passengers comfortably.  The aft portion of the cabin has an enclosed potty and a baggage area capable of handling 550 lbs of bags. It cruises at 310 kts and has a range of 1,700 nm. This capable twin has a max takeoff weight of 15,000 lbs which means that unlike the king air 200 a 350 captain must be type rated in the aircraft. With a nine passenger seat configuration you can carry nine passengers and a full load of fuel. At max takeoff weight, at sea level, on a 30o C day, with flaps  up, bleed air open and air-conditioning on the takeoff distance is 5,015 ft. Under the same conditions with the flaps at approach the takeoff distance is 4,187 ft.

Rudder Boost must be operational for all flights

Yaw damp is required above 5,000 ft. If dual strakes are installed yaw damp must be operational above 19,000 ft

Prop speed of 1768 indicates failure of the primary governor. Limit torque to 96% and flight may be continued.

Over speed governor limits speed to 1768 rpm by dumping oil from the prop

Fuel topping governor limits prop to 106% of selected rpm, also limits reverse to 95% n1

Speeds above 1768 rpm indicate primary and over speed governor failure

Auto feather must be operational for takeoff, climb, approach and landing.
Both power levers must be above 90% N1
If torque drops below 17% the other side disarms
If torque drops below 10% the prop feathers

Auto ignition activates at 17% torque

Pneumatic pressure normal operating range 12-20 psi

AC compressor is on the right engine, automatically cuts out if-
Refrigerant pressure too high or low
Ambient temp below 10oC
Right engine below 62% N1

Electric heat – for ground use only
Temperature controller must be in manual heat
Both forward and aft blowers must be on
Electric heat light must out before turning off blowers

Landing gear warning horn activates and the gear handle illuminates red when-
Flaps up or at approach, Power below 85% N1 and gear not down. Can be cancelled
Flaps beyond approach and gear not down. Cannot be cancelled
On the ground with the handle in the up position

Cabin pressure switch –DUMP- dumps cabin with a limit of 13,500 ft cabin altitude

BAT BUS switch – opens a RCCB between the battery bus and the battery (isolates the battery)

Battery switch – closes the battery relay and the battery bus tie to power the triple fed and center busses

BATTERY CHARGE Illuminates at 7.5 amps. Extinguishes at 6 amps

Flight idle low pitch stop – is a mechanically activated hydraulic stop. Set on ground as power climbs above 68-70% N1 and L/R PROP PITCH extinguishes

Ground idle low pitch stop – electrically actuated solenoid set at 10o below the flight idle pitch stop. The right squat switch de-powers the stop at lift off.

If in flight the solenoid receives power for more than 10 seconds PROP GND SOL illuminates – pulling the PROP GOV TEST circuit breaker de-powers the solenoid – the light is inhibited on the ground by the left squat switch.

L/R PROP PITCH – indicates the prop is more than 8o below the flight idle pitch stop

Compressor bleed valve – a pneumatic piston that ports P2.5 Air to prevent compressor stalls

Jet flap – vents P2.5 Air through a variable slot in each hollow strut that connects the accessory section to the compressor this produces a swirl effect for air entering the compressor, to improve low speed compressor characteristics.

Hot battery bus lights– entry way lights, baggage light, emergency lights

10,000 ft  CABIN ALTITUDE illuminates
12,000 ft  CABIN ALT HI illuminates
12,500 ft passenger oxygen mask deploy
13,500 cabin dumb switch limit

king Air 350 Instrument Panel

The Beechcraft Super King Air 350 is a large twin engine turboprop capable of comfortably carrying 8 to 12 passengers. Two Pratt and Whitney PT6A-60A 1,050 shp turbo prop engines  give this popular corporate aircraft has the ability to operate out of short runways with heavy loads and fly 1700 nm at 310 kts. The panel is from an early serial number aircraft with analog flight instruments and a Garmin 500 installed. For more info, specs and limitations on the KA 350.
