H - Horizontally Opposed
A - Air-Cooled
N - Normally Aspirated
D - Direct Drive

360 Cubic Inches
Fuel-Injected

Question 2

Describe the propeller.

Answer 2

McCauley, 76 inch, 2 blade, all metal, fixed pitch propeller.

Question 3

Describe the fuel system.

Answer 3

1 Tank in Each Wing –> Fuel Selector –> Reservoir –> Fuel Shutoff Valve –> Aux Fuel Pump –> Strainer –> Engine Driven Fuel Pump –> Air/Fuel Mixture –> Manifold Distribution Chamber

Fuel Burn : 10 GPH
Fuel Capacity : 56 Gallons
Useable Fuel : 53 Gallons
Oil Sump : 10 Quarts

Question 4

Describe the braking system.

Answer 4

Hydraulically actuated disc type brakes on both the main landing gear wheels connected to master cylinders which are connected to the rudder pedals on both sides of the cockpit.

Question 5

Describe the landing gear system.

Answer 5

Tricycle, fixed landing gear system. Both the main wheels are connected and held by metal legs. The front wheel is connected to an Oleo (oil/air) strut that absorbs shock.

Question 6

Describe the vacuum system.

Answer 6

2 engine driven vacuum pumps connect to a manifold check valve, which connects and powers the gyros powering the attitude indicator and the heading indicator, then from the heading indicator it connects to the suction gauge, then finally both connect to a filter.

Question 7

What is the max horsepower?

Answer 7

180 HP

Question 8

What is the maximum weight?

Answer 8

2,550 lbs

Question 9

What is the stall speed in landing configuration (Vs0)?

Answer 9

40 knots

Question 10

What is the stall speed in clean configuration (Vs1)?

Answer 10

48 knots

Question 11

What is the best angle-of-climb (Vx)?

Answer 11

62 knots

Question 12

What is the best rate-of-climb (Vy)?

Answer 12

74 knots

Question 13

What is the rotation speed (Vr)?

Answer 13

55 knots

Question 14

What is the maximum structural cruising speed (Vno)?

Answer 14

129 knots

Question 15

What is the never exceed speed (Vne)?

Answer 15

163 knots

Question 16

What is the best glide speed (Vg)?

Answer 16

68 knots

Question 17

Describe the electrical system.

Answer 17

Equipped with a 28 volt DC electrical system and a 24 volt lead-acid battery. Electrical energy is supplied by a 60 AMP alternator located on the front end of the engine. Electrical power is distributed through electrical buses and circuit breakers.

Question 18

Describe the stall warning system.

Answer 18

A pneumatic type stall warning system consists of an inlet on the left wing leading edge, which is ducted to a horn near the top left of the windshield. As the aircraft approaches a stall, the lower pressure on top of the wing shifts forward drawing air through the horn resulting in a warning noise.
