COMMERCIAL PILOT TEST PREP CHAPTER 1 QUESTIONS AND
VERIFIED DETAILED SOLUTIONS ( MULTIPLE CHOICES) |100%
CORRECT!!
When the angle-of-attack of a symmetrical airfoil is increased, the center of pressure will - (ANSWER)not
move
A symmetrical airfoil moving through the air at zero degrees angle-of-attack - (ANSWER)will cause similar
acceleration of the airflow over both upper and lower surfaces, similar velocities of flow generating
similar pressures and therefore no lift.
The lift generated by an airfoil is - (ANSWER)proportional to the square of the velocity of the relative
airflow
If the airplane attitude remains in a new position after the control column is pressed forward and
released, the airplane is said to display - (ANSWER)neutral longitudinal static stability.
If the airplane attitude oscillates about its original position before gradually settling down after the
control column is pressed forward and released, the airplane is said to display - (ANSWER)positive
dynamic stability.
Longitudinal dynamic instability in an airplane can be identified by - (ANSWER)pitch oscillations
becoming progressively steeper.
If a tire has moved so that the creep marks are out of alignment, then - (ANSWER)the tire should be
inspected and possibly reinstalled or replaced.
Most light airplane braking systems are operated - (ANSWER)Hydraulically
How many hours are required for completion of the Commercial Certificate, following a Part 141
program? - (ANSWER)190 hours of flight training, 100 hours of ground training.
What is density altitude? - (ANSWER)The pressure altitude corrected for nonstandard temperature.
