13. Explain how you should recover from a chandelle.
14. What can you expect with regard to control pressures at the completion of a 180 degree change in direction during a chandelle? Explain.

10. Explain the correct use of the controls during a crosswind takeoff.
11. Assume a left crosswind during a landing approach. Explain the correct use of the controls during the approach, flare, and landing.
12. What is the maximum demonstrated crosswind component for the aircraft? Is this a limitation? Explain.
13. If the aircraft is low and slow on final approach, what corrective action should you take?
14. Explain the procedures for executing a go-around in the aircraft.
15. What is the significance of the "key position" during a landing?
16. During a short-filed approach and landing, how accurately must you land the aircraft relative to a selected touchdown point?

Lazy Eights and Pylon Eights

1. Compare and contrast eights-around-pylons and eights-on-pylons. Which of these is considered to be a ground reference maneuver?
2. At what altitude should you enter eights-around-pylons?
3. What is the maximum angle of bank that you should use during eights-round-pylons? Where will this bank angle occur?
4. How does wind direction affect the entry for eights-around-pylons?
5. What is the maximum angle of bank you should use for eights-on-pylons?
6. Describe how you make changes in altitude during eights-on-pylons to hold the pylon position relative to the wing.
7. Where do the highest and lowest altitudes occur during the performance of eights-on-pylons?
8. What reference points do you use during the performance of lazy eights?
9. Where do the highest and lowest altitudes occur during lazy eights?
10. Do you use pitch or power to control the altitude and symmetry of the loops during lazy eights?
11. What altitude and airspeed should you use to enter lazy eights?

Cross-Country Procedures Briefing

1. Explain what weather product you would use to obtain the most current weather condition at your destination?
2. What is the meaning of code "9900" found on a winds aloft forecast?

To answer questions 3 thru 8, use the appropriate pilot's operating handbook.

3. compute the density altitude based on the following conditions.
Field elevation..........4,000 ft.
Temperature..........24 deg. C
Altimeter setting..........30.00
4. Using the date from the previous question, determine the distance required to take off and clear a 50-foot obstacle, assuming maximum takeoff weight and a 10 knot headwind.
5. Determine the time, fuel, and distance needed to climb from a field elevation of 2,000 feet to a cruising altitude of 7,500 feet. Assume standard conditions and calm wind.
6. Based on a cruise altitude of 7,500 feet and standard conditions, determine the true airspeed and fuel flow at approximately 65% power.
7. Using data from the previous question, what is the maximum range of the aircraft with full fuel?
8. Based on the following conditions, determine the distance required to land over a 50-foot obstacle.
Field elevation..........3,000 ft
Temperature..........ISA +20 deg. C
Altimeter setting..........29.92
Wind..........Calm
9. What are the basic VFR weather minimums? What are they in a traffic pattern in controlled airspace?
10. What is a special VFR clearance? Can you request it at night? What visibility and cloud clearances apply?
11. What are the pilot and equipment requirements to fly above 18,000 feet MSL?
12. What is the purpose of Class E airspace when it surrounds a nontowered airport?
13. What are the effective altitudes for Class E airspace in the vicinity of an airport?
14. Name the various types of special use airspace and explain the restrictions they impose.
15. How can you tel when the control tower is in operation at part-time locations?
