Chapter 4 - Loading and Performance

Question 1

What must a person who is manipulating the controls of a small unmanned aircraft do if the standard remote identification fails during flight?

Answer 1

Land the aircraft as soon as practicable.

Question 2

Who is responsible for ensuring that there are enough crewmembers for a given sUAS operation?

Answer 2

Remote pilot-in-command.

Question 3

No person may attempt to act as a crewmember of a sUAS with

Answer 3

.04 percent by weight or more alcohol in the blood.

Question 4

(Refer to Figure 75, Area 6.) During preflight planning, you plan to operate in R-2305. Where would you find additional information regarding this airspace?

Answer 4

In the Special Use Airspace area of the chart.

Question 5

What is required to enter an airport SIDA?

Answer 5

You must have an airport-issued or approved ID.

Question 6

Which of the following considerations is most relevant to a remote PIC when evaluating unmanned aircraft performance?

Answer 6

Current weather conditions

Question 7

Which of the following is true regarding weight and balance of small unmanned aircraft?

Answer 7

Operations outside weight and balance limitations may result in loss of control.

Question 8

You are operating an sUAS that does not have GPS or an installed ground speed limiter. How can you determine the speed you are operating?

Answer 8

Dead reckoning.

Question 9

What purpose does a rudder perform on an sUAS airplane?

Answer 9

The rudder controls yaw.

Question 10

When range and economy of operation are the principle goals, the remote pilot must ensure that the sUAS will be operated at the recommended

Answer 10

long-range cruise performance.

Question 11

Maximum endurance is obtained at the point of minimum power to maintain the aircraft

Answer 11

in steady, level flight.

Question 12

The term “angle of attack” is defined as the angle

Answer 12

between the wing chord line and the relative wind

Question 13

What effect does an uphill terrain slope have on launch performance?

Answer 13

Increases launch distance.

Question 14

In a 45 degree banking turn, a small unmanned aircraft will

Answer 14

stall at a higher airspeed

Question 15

A small unmanned aircraft loaded with the most rearward center of gravity is

Answer 15

less stable at all speeds.

Question 16

(Refer to Figure 2.) If an unmanned airplane weighs 33 pounds, what approximate weight would the airplane structure be required to support during a 30 degree banked turn while maintaining altitude?

Answer 16

38 pounds.

Question 17

Scheduled maintenance should be performed in accordance with the

Answer 17

Manufacturers’ suggested procedures.

Question 18

During your preflight inspection, you discover that the casing of your sUAS battery has expanded beyond its normal dimensions. What action should you take?

Answer 18

Follow the manufacturer’s guidance.

Question 19

You are operating an sUAS that does not have GPS or an installed altimeter. How can you
determine the altitude you are operating?

Answer 19

Gaining a visual perspective of what 400 feet looks like on the ground before the flight.

Question 20

The most critical conditions of launch performance are the result of some combination of
high gross weight, altitude, temperature, and

Answer 20

unfavorable wind.

Question 21

The amount of excess load that can be imposed on the wing of an airplane depends upon
the

Answer 21

speed of the airplane.

Question 22

What effect does an uphill terrain slope have on launch performance?

Answer 22

Increases launch distance.

Question 23

An increase in load factor will cause an unmanned aircraft to

Answer 23

stall at a higher airspeed.

Question 24

When loading cameras or other equipment on an sUAS, mount the items in a manner that

Answer 24

does not adversely affect the center of gravity.
