Question 1

Airspeed Limitations

Accepted Answer

SPEED:  VS     Maximum Stall Speed at Maximum takeoff weight
CAS (mph/kts):   48 / 42
 
SPEED:  VA  Design Maneuvering Speed
CAS (mph/kts):   115 / 100
REMARKS:  Do not make full or abrupt control movements above this speed.
 
SPEED:   VNE Never Exceed Speed
CAS (mph/kts):  145 / 126
REMARKS:  Do not exceed this speed in any operation.
 
SPEED:  VC Design Cruising Speed
CAS (mph/kts):  120 / 105
REMARKS:  Do not exceed this speed except in smooth air and then only with caution.

Question 2

Best Angle of Climb

Accepted Answer

Best angle of climb Vx is 65 mph CAS, full power at 1320 lbs.

Question 3

Cruise Speeds & RPM

Accepted Answer

Cruise speeds and RPM in standard atmosphere and 75% power
(above 7,000 ft. the power is less)
 
ALTITUDE :  S.L. = 0 
RPM:  2500 
CAS (mph/kts):  120/104 
RANGE (mph):  500+

ALTITUDE :  3,000 feet
RPM:  2600
CAS (mph/kts):  124/108
RANGE (mph):  500+
ALTITUDE :  6,000 feet
RPM:  2700
CAS (mph/kts):  128/112
RANGE (mph):  500+
ALTITUDE:  9,000 feet (less than 75%)
RPM:  2750
CAS (mph/kts):  117/102
RANGE (mph):  500+
At 75% power, the fuel consumption is about 5 gal/hr.
With 2 x 12.5 = 24 gal. fuel tanks full, the endurance is about 4  hours with about 30 minutes of reserve (unusable fuel is not less than 1 gallon for each tank).

Question 4

Crosswind

Accepted Answer

The demonstrated takeoff and landing crosswind component is 20 kts.

Question 5

Service Ceiling

Accepted Answer

Where rate of climb is 100 FPM in standard atmosphere: 17,000 feet.

Question 6

Stall Speed at 1,320 lbs. (Max. takeoff weight)"

Accepted Answer

Vs  =  48 mph CAS

Question 7

Take-off Roll:  From hard surface, full power at brake release"

Accepted Answer

S.L. = 0
Std. Temp:  600
Above values are in feet
On grass, increase above values by 20% approximately.

Question 8

Take-off Roll + Climb to Clear 50 ft obstacle at 60 mph CAS

Accepted Answer

From hard surface, full power at brake release
 
S.L. = 0
Std Temp:  950
Above values are in feet
On grass, increase above values by 20% approximately.
With headwinds, above values are decreased by 25% for 10 kt headwind and 40% for 20 kt headwind.

Question 9

Landing Distance

Accepted Answer

Landing distance from 50 ft. height, throttle idle, approach speed = 55 mph CAS
 
S.L. = 0
Std. Temp 1000 ft
