Commercial Flight Maneuvers Flashcards
What is a steep turn? (FAA-H-8083-3)
Steep turns are those resulting from a degree of bank (more than approximately 45 degrees) at which the overbanking tendency of an airplane overcomes stability, and the bank tends to increase unless pressure is applied to the aileron controls to prevent it. Maximum turning performance is attained and relatively high load factors are imposed.
What is the desired bank angle in a steep turn? (FAA‑S‑ACS-7)
A bank angle of at least 50° (±5°) is desired.
What is the recommended entry speed for a steep turn? (FAA‑S‑ACS-7)
Establish the manufacturer’s recommended airspeed or if one is not stated, a safe airspeed not to exceed VA.
How do you maintain altitude in a steep turn? (FAA-H-8083-3)
To maintain bank angle and altitude, as well as orientation, requires an awareness of the relative position of the horizon to the nose and the wings. If the altitude begins to increase or decrease, changing elevator back pressure can be used to alter the altitude; however, a more effective method is a slight increase or decrease in bank angle to control small altitude deviations. If the altitude is decreasing, reducing the bank angle a few degrees helps recover or stop the altitude loss trend; if the altitude is increasing, increasing the bank angle a few degrees will help recover or stop the altitude increase trend.
What are the altitude, airspeed, bank, and heading tolerances for a steep turn? (FAA‑S‑ACS-7)
Maintain the entry altitude, ±100 feet, airspeed, ±10 knots, bank, ±5°; and roll out on the entry heading, ±10°.
What is a chandelle? (FAA-H-8083-3)
A “chandelle” is a maximum performance climbing turn beginning from approximately straight and level flight, and ending at the completion of 180° of turn in a wings-level, nose-high attitude at the minimum controllable airspeed.
In a chandelle, constant bank and changing pitch occur in what part of the maneuver? (FAA-H-8083-3)
The first 90° of turn require a constant 30° of bank and a gradual and constant change in pitch attitude.
In a chandelle, constant pitch and changing bank occur in what part of the maneuver? (FAA-H-8083-3)
The last 90° of turn requires a very gradual change in bank from 30° to 0° and a constant pitch attitude so as to arrive at minimum airspeed as the airplane is rolled out to a wings-level attitude.
What is the maximum amount of bank in the chandelle? (FAA‑S‑ACS-7)
30° of bank.
What should your speed be upon completion of the chandelle? (FAA‑S‑ACS-7)
You should begin a coordinated constant-rate rollout from the 90° point to the 180° point, ±10° just above a stall airspeed, and maintaining that airspeed momentarily avoiding a stall.
At what two points will your wings be level in a chandelle? (FAA‑S‑ACS-7)
Immediately before entering the chandelle and upon rollout at the 180° point.
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.
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.
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.
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.
What are the altitude, airspeed and heading tolerances allowed when performing a lazy eight? (FAA-S-ACS-7)
You should achieve the following throughout the maneuver:
a. Approximately 30° bank at the steepest point.
b. Constant change of pitch, roll rate, and airspeed.
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°.
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)

What are eights-on-pylons? (FAA-H-8083-3)
Eights-on-pylons is a training maneuver that involves flying the airplane in circular paths, alternately left and right, in the form of a figure-8 around two selected points or pylons on the ground. No attempt is made to maintain a uniform distance from the pylon. Instead, the airplane is flown at such an altitude and airspeed that a line parallel to the airplane’s lateral axis, and extending from the pilot’s eye appears to pivot on each of the pylons.
How do you determine pivotal altitude for eights-on-pylons? (FAA-H-8083-3)
A rule of thumb for estimating pivotal altitude using true airspeed in no-wind conditions, or ground speed when the wind is blowing, is to square the speed and divide by 15 for miles per hour or 11.3 for knots.
Does the pivotal altitude change in eights-on-pylons? (FAA-H-8083-3)
Yes, the pivotal altitude is critical and will change with variations in ground speed. Since the headings throughout the turns continually vary from directly downwind to directly upwind, the ground speed will constantly change. This will result in the proper pivotal altitude varying slightly throughout the eight. Therefore, adjustment must be made for this by climbing and descending as necessary to hold the reference line or point on the pylons. This change in altitude will be dependent on how much the wind affects the ground speed.
Remember…
Ground speed goes UP, Pivotal Altitude goes UP.
Ground speed goes DOWN, Pivotal Altitude goes DOWN.
How far should one pylon be from the other pylon in eights-on-pylons? (FAA-S-ACS-7)
They should be of sufficient distance apart to permit straight and level flight between pylons.
At the steepest point, the bank angle in an eights-on-pylon maneuver should be what value? (FAA-S-ACS-7)
Establish the correct bank angle for the conditions, not to exceed 40°.
Where is the highest pivotal altitude likely to occur in eights-on-pylons? (FAA-H-8083-3)
As the airplane turns downwind the ground speed increases; consequently the pivotal altitude is higher and the airplane must climb to hold the reference line on the pylon.
Where is the lowest pivotal altitude likely to occur in eights-on-pylons? (FAA-H-8083-3)
As the airplane heads into the wind, the ground speed decreases; consequently the pivotal altitude is lower and the airplane must descend to hold the reference line on the pylon.
