Pilatus PC-6 Turbo Porter The Jeep of the Air

Utility Airplane �What is it good for? �Hauling people and cargo into and out of somewhere that is otherwise accessible only by helicopters �Has many configuration options and quick conversions – Yeah it has trap doors so be nice to the pilot! � https: //www. youtube. com/watch? feature=player_embedded&v=eu. Ol. F YZIITw Example of STOL

Where can it operate? �Cold: to -67 degrees F �Hot: to 131 degrees F �Desert (Sand), Rocky terrain �High density altitudes �Snow / Water � https: //www. youtube. com/watch? v=92 Er. Tsi. Mw. Lw �Max operating altitude is 25, 000 feet �It can even handle an occasional paved runway

Design Basics

Weight & Fuel � 3, 080 pound empty weight � 6, 173 pound take-off weight �Wing tanks = 170 gallons �Optional under wing tanks = 128 gallons � 39 gallons per hour

Distances and Rates �Normal Take-off ground roll 646’ �Normal Distance to 50’ 1, 558’ �STOL take off distance 1, 443’ �STOL Landing ground roll 417’ �STOL Landing distance (50’) 1, 033’ �https: //www. youtube. com/watch? v=np. EY 7 z. TZ 3 C 8 �Climb rate at sea level / 5, 000’ 1, 010 / 935 fpm

Let’s Talk About That Engine �Unlike a piston turbo, it is normally aspirated �It taps into its “extra” power as it encounters less dense air �What does 680 SHP flat-rated to 550 SHP mean? � 130 SHP in the bank! �This is the source of its superior high altitude capability and stable climb rate

Propeller Capabilities �A GA airplane with REVERSE �What is Beta Mode? �Skydive 1 �Reverse

Control and Maneuverability Peter Collins review of the modern Porter: �“I found the PC-6 easy, pleasant and accurate to fly. The control forces were light and well harmonised. The aircraft felt nimble in roll with a sustained roll rate of around 60°/s. Strong adverse yaw was exhibited with any large lateral stick input, but this was quickly corrected by the fin. ”

Maintainability and Reliability �Yes to both �They are built by hand the builders actually sign their names to the airframe in the tail section. �Engine has few moving parts & is easily accessed.

Cost �Operating : $320/Hr �Buy one new for “just” $1, 800, 000 �Includes: $179. 0 o Fuel, engine reserve, prop reserve, oil consumption, maintenance labor hours �Partial Engine Overhaul �Total Engine Overhaul: �Prop Overhaul: � 100 hour inspection: $20, 000 $40, 000 $11, 500 $3200

Disadvantages �Yeah, it’s slow for an airplane �High wing is less maneuverable than a low wing �T-tail / V-tail have better spin recovery �The trim for the pitch axis has a large amount of authority, so any malfunction causes major control issues �Visually unattractive

I still don’t see the downside… �Versatile, rugged, reliable, and capable Landing on foot path
