@ 50 knts, add full PWR & Max pitch up
Watch for stall symptoms
Recover from the stall
PWR Off Stall
Clearing turns
Set PWR to 1,500 RPM
Set Flaps to T/O (Vfe T/O)
Set Flaps to LDG (Vfe LDG)
Simulate descent @ 65 knts (PWR idle) w/ 200'
@ 200' Simulate Flare
Watch for stall symptoms
Recover from the stall
Turns Around a Point
Perform pre-maneuver checks
Select a reference point
Set power to maintain an airspeed of 90 KIAS
Maintain 1000’ AGL
Clear the area of other aircraft
Trim the airplane for level flight
First turn to the left at the highest ground speed and steepest bank angle (max 45 degrees)
Bank angle will gradually need to be decreased to the upwind point (slowest ground speed)
From the upwind point, bank angle will need to gradually increase to the downwind point (fastest ground speed)
S-Turns
1. Perform pre-maneuver checks
2. Select a line feature that lies crosswind (road, etc.)
3. Set power to maintain an airspeed of 90 KIAS
4. Maintain 1000’ AGL
5. Trim the airplane for level flight
6. Approach the line feature downwind
7. Cross the line feature wings level
8. Initial turn is to the left at the fastest ground speed and steepest bank angle (not to exceed 30 degrees)
9. Directly crosswind moderate bank angle and decrease as the airplane turns upwind
10. Maintain coordinated flight throughout
11. Cross the line feature while rolling wings level
12. Upwind turn begins in the opposite direction with a shallow bank angle
13. Increase bank angle to moderate at the crosswind position
14. Continue to increase bank angle through the turn to downwind
15. Cross the line feature with wings level
16. Exit the maneuver at the same altitude and airspeed
Chandelles
Constant Bank, Changing Pitch
Changing Bank, Constant Pitch
Perform pre-maneuver checks
Start @ 3,500’ AGL
Clearing turns
Set power to around 90 KIAS
(POH recommends 116 KIAS)
Pick a 90-degree reference point off wing tip.
Add Full PWR when starting the maneuver
Roll into a 30-degree bank.
After the bank is established, smoothly and continuously increase the pitch, and simultaneously add climb power to arrive at the 90-degree point with maximum pitch up.
Upon reaching the 90-degree point, begin rolling out slowly to arrive at the 180-degree point with maximum pitch up, wings level, and the airspeed at approximately 50-55 KIAS.
At the 180-degree point of the maneuver, complete the cruise checklist
Lazy Eights
Perform pre-maneuver checks
Start @ 3,000’ AGL
Clearing turns.
Set power to around 90 KIAS
POH recommends 116 KIAS
Select a heading that will establish the aircraft perpendicular to a well-defined reference line. Select visual references at the 45 and 135 degree points relative to the direction of the maneuver.
Initiate the maneuver by slowly increasing the pitch while simultaneously rolling into a bank to arrive at the 45-degree point with maximum pitch up and 15 degrees of bank.
Passing the 45-degree point, increase the bank and decrease the pitch to arrive at the 90-degree point with 30 degrees of bank and pitch attitude passing through level.
As the aircraft passes through the 90-degree point, continuously decrease the pitch, and decrease the bank to reach maximum pitch down and 15 degrees of bank at the 135-degree point.
Passing the 135-degree point, continuously decrease the bank and increase the pitch so the aircraft is straight and level upon reaching the 180-degree point.
After completion of the first 180-degree circuit, perform the maneuver in the opposite direction
Upon completion of the maneuver, complete the Cruise configuration.
Steep Spirals
Perform pre-maneuver checks
Select an altitude that will allow for three 360-degree descending turns
4,000’ MSL
Select a suitable ground reference point.
Enter the maneuver downwind.
Before reaching the abeam point on downwind, reduce power to idle and hold altitude.
Time maneuver to reach the abeam point at best glide speed (73 KIAS)
Abeam the reference point roll into a bank(~45 degrees)
Begin a constant radius turn around a point, compensating for wind drift by continuously changing the wind correction angle and bank (using a maximum of 60 degrees of bank.)
Adjust pitch to maintain best glide speed.
Divide attention between aircraft control and maintaining ground track.
During descent, power is occasionally applied power to keep engine warm.
Make 3 constant radius turns around the reference point.
Exit maneuver on downwind, no lower than 1,500’ AGL
Upon completion of the maneuver, re-establish training cruise and complete the post-maneuver check.
8’s on pylons
Perform pre-maneuver checks
Calculate pivotal altitude prior to flight, (PA=Ground speed squared divided by 11.3)
Clearing turns
Establish 90 KIAS for entry
Select suitable reference points (“pylons”) and position the aircraft so the maneuver will be entered on a heading 45 degrees to downwind.
When the pylon passes below the wing, smoothly roll into a turn using coordinated aileron and rudder so that the pylon maintains a constant position relative to the wingtip.
As the turn around the pylon progresses, make pitch changes to compensate for variations in ground speed and maintain the pylon’s position relative to the wingtip.
Pylon forward- control forward- reduce bank
Pylon rearward- control rearward- increase bank.
