What is the best way to do a falling leaf maneuver?
What happens when you do a falling leaf with the following:

 

No flaps?

 

1 Notch?

 

2 Notches?

 

3 Notches?

 

What tendencies?

What recovery techniques have you been using?
Are there any recovery techniques that could be dangerous?
Return to airport to inspect the aircraft prior to the next flight.

Takeoff and Landing Performance

Record the following takeoff and landing data on asphalt: 

 

WITH ONE PILOT, LOW FUEL

 

No flaps?

 

1 Notch?

 

2 Notches?

 

3 Notches?

 

AT GROSS WEIGHT

 

No flaps?

 

1 Notch?

 

2 Notches?

 

3 Notches?

Record the following takeoff and landing data on grass: 

 

WITH ONE PILOT, LOW FUEL

 

No flaps?

 

1 Notch?

 

2 Notches?

 

3 Notches?

 

AT GROSS WEIGHT

 

No flaps?

 

1 Notch?

 

2 Notches?

 

3 Notches?

Record any runway data you can gather during other flight tests, 

i.e. with 10mph wind, etc.

Lift and Drag performance Ratios, Power on and off

Climb for 1 minute and record the VSI reading along with actual 

altimeter readings at start and finish if possible.  This data must 

be duplicated with 2 runs and will be graphed.  Do everything 

one time, then repeat in reverse order to get an average for 

changing fuel conditions.  Do everything at the same altitude on 

the same day, preferably 3500MSL thru 4500MSL range
Generate the following FPM climb data with no flaps:

 

40mph

 

45mph

 

50mph

 

55mph

 

60mph

 

65mph

 

70mph

 

75mph

 

80mph

Generate the following FPM climb data with 1 notch:

 

35mph

 

40mph

 

45mph

 

50mph

 

55mph

 

60mph

 

65mph

 

70mph

Generate the following FPM climb data with 2 notches:

 

35mph

 

40mph

 

45mph

 

50mph

 

55mph

 

60mph

 

65mph

Generate the following FPM climb data with 3 notches:

 

35mph

 

40mph

 

45mph

 

50mph

 

55mph

 

60mph

 

65mph

Generate the following sink FPM power-off data with no flaps:
