DONE 9C Commercial Flight Maneuvers - Lazy Eights Flashcards

2. What procedures are recommended prior to beginning a lazy-eight maneuver? (FAA-H-8083-3)
Prior to performing a lazy eight, the airspace behind and above should be clear of other air traffic. The maneuver should be entered from straight-and-level flight at normal cruise power and at the airspeed recommended by the manufacturer or at the airplane’s design maneuvering speed.

1. What is a lazy eight? (FAA-H-8083-3)
A lazy eight consists of two 180° turns, in opposite directions, while making a climb and a descent in a symmetrical pattern during each of the turns.

3. Where should the highest pitch attitude occur in a lazy eight? (FAA-H-8083-3)
At the 45° point the pitch attitude should be at a maximum and the angle of bank continuing to increase. Also, at the 45° point, the pitch attitude should start to decrease slowly toward the horizon at the 90° reference point.

4. Where should the lowest nose-down attitude occur in a lazy eight? (FAA-H-8083-3)
When the airplane has turned 135°, the nose should be at its lowest pitch attitude.

5. What are the altitude, airspeed and heading tolerances allowed when performing a lazy eight? (FAA-S-8081-12)
You should achieve the following throughout the maneuver:
a. Approximately 30° bank at the steepest point.
b. Constant change of pitch and roll rate.
c. Altitude tolerance at 180° points, ±100 feet (30 meters) from entry altitude.
d. Airspeed tolerance at the 180° point, ±10° knots from entry airspeed.
e. Heading tolerance at the 180° point, ±10°.

6. To summarize, describe the appropriate values to be obtained in a lazy eight at the entry, 45-, 90-, 135- and 180-degree points. (FAA-H-8083-3)
Entry — Level flight — Maneuvering or cruise speed (whichever is less) or manufacturer’s recommended speed 45° point — Maximum pitch-up attitude — Bank angle at 15° 90° point — Bank angle approximately 30° — Minimum airspeed — Maximum altitude — Level pitch attitude 135° point — Maximum pitch-down attitude — Bank approximately 15° 180° point — Level flight — Original heading (±10°) — Entry airspeed (±10 knots) — Entry altitude (±100 feet)
