(from the FAA Commercial Pilot Rating Knowledge Test)

1). The magnetic heading is 350° and the relative bearing to a radiobeacon is 240°. What would be the magnetic bearing TO that radiobeacon?

a). 050°.
b). 230°.
c). 295°.

2). On a Surface Analysis Chart, the solid lines that depict sea level pressure patterns are called

a). millibars.
b). isogons.
c). isobars.

3). Virga is best described as

a). wall cloud torrents trailing beneath cumulonimbus clouds which dissipate before reaching the ground.
b). streamers of precipitation trailing beneath clouds which evaporates before reaching the ground.
c). turbulent areas beneath cumulonimbus clouds.

4). The most current en route and destination weather information for an instrument flight should be obtained from the

a). ATIS broadcast.
b). AFSS.
c). Notices to Airmen publications.

5). Which statement is true about magnetic deviation of a compass? Deviation

a). varies for different headings of the same aircraft.
b). is the same for all aircraft in the same locality.
c). varies over time as the agonic line shifts.

6). The mixture control can be adjusted, which

a). prevents the fuel/air combination from becoming too rich at higher altitudes.
b). regulates the amount of air flow through the carburetor's venturi.
c). prevents the fuel/air combination from becoming lean as the airplane climbs.

7). Which airspeed would a pilot be unable to identify by the color coding of an airspeed indicator?

a). The power-off stall speed.
b). The maneuvering speed.
c). The never-exceed speed.

8). What is an advantage of an electric turn coordinator if the airplane has a vacuum system for other gyroscopic instruments?

a). It will not tumble as will vacuum-driven turn indicators.
b). It is a backup in case of vacuum system failure.
c). It is more reliable than the vacuum-driven indicators.

9). One of the main functions of flaps during the approach and landing is to

a). decrease the angle of descent without increasing the airspeed.
b). provide the same amount of lift at a slower airspeed.
c). decrease lift, thus enabling a steeper-than-normal approach to be made.

10). Which is true about homing when using ADF during crosswind conditions? Homing

a). to a radio station results in a curved path that leads to the station.
b). to a radio station requires that the ADF have an automatically or manually rotatable azimuth.
c). is a practical navigation method for flying both to and from a radio station.
