Principal Dimensions

How big the SR20 is outside and in: span, length and height, the space in the cabin and the baggage compartment, and how much room it needs to turn on the ground.

Outside

The wingspan is 38.3 ft (11.67 m), read on the front view. The side view gives an overall length of 26.0 ft (7.92 m) and an overall height of 8.9 ft (2.71 m). The main wheels stand 9.1 ft (2.8 m) apart.

The three-view draws a 3-blade propeller 74 inches (188 cm) across.

Inside

Cabin

• Length: 122 in

• Width: 49.3 in

• Height: 49.7 in

• Volume: 137 cu ft

Baggage compartment

• Length: 36 in

• Width: 39.8 in

• Height: 38.5 in

• Volume: 32 cu ft

Ground turning clearance

Four radii describe a tight turn on the ground. The wing tip sweeps the largest circle and the inside gear the smallest.

Turning radii

• Wing tip: 24.3 ft (7.41 m)

• Outside gear: 9.1 ft (2.77 m)

• Nose gear: 7.0 ft (2.16 m)

• Inside gear: 0.5 ft (0.15 m)

These radii are calculated with one brake and partial power. In practice the radius may differ by as much as three feet.

Check yourself

• What are the SR20's wingspan, overall length and overall height?

• How far apart are the main wheels?

• Which part of the airplane sweeps the largest radius in a ground turn, and how large is it?

• Under what conditions were the turning radii calculated, and by how much can the real radius differ?
