Part 107 loading and performance practice test
20 questions · Updated October 6, 2026
Loading and performance is 7–11% of the test, and the only part with arithmetic. The load factor questions use one table from the FAA testing supplement; once you know how to read it, each one takes a single multiplication.
What this test covers
Load factor in turns, why stall speed rises with it, weight and balance and the center of gravity, the four forces, stability, and how heat, altitude and humidity reduce performance. Our load factor guide works through the chart step by step.
| Bank angle | Load factor (G) |
|---|---|
| 0° | 1 |
| 10° | 1.015 |
| 30° | 1.154 |
| 45° | 1.414 |
| 60° | 2 |
| 70° | 2.923 |
| 80° | 5.747 |
| 85° | 11.473 |
| 90° | Not possible in level flight |
(Refer to Figure 2.) If an unmanned airplane weighs 33 pounds, about how much weight must its structure support during a 30° banked turn while maintaining altitude?
- A34 pounds
- B38 pounds
- C47 pounds
Show answer
B. 38 pounds
The load factor at 30° of bank is 1.154. Multiply by the weight: 33 × 1.154 ≈ 38 pounds.

A stall occurs when the smooth airflow over an unmanned airplane's wing is disrupted and lift degenerates rapidly. This happens when the wing
- Aexceeds its maximum speed
- Bexceeds its critical angle of attack
- Cexceeds its maximum allowable weight
Show answer
B. exceeds its critical angle of attack
A stall is caused by exceeding the critical angle of attack. It can happen at any airspeed if a high enough angle of attack is imposed.

When operating an unmanned airplane, the load factor on the wings may increase any time
- Athe CG is shifted to the aft limit
- Bthe airplane is maneuvered other than in straight-and-level flight
- Cthe gross weight is reduced
Show answer
B. the airplane is maneuvered other than in straight-and-level flight
Any force that deflects the flight path from a straight line, such as a turn or pull-up, stresses the structure and increases the load factor.

To make sure the unmanned aircraft's center of gravity (CG) limits are not exceeded, follow the loading instructions in the
- APilot's Operating Handbook or UAS Flight Manual
- BAeronautical Information Manual
- CChart Supplement U.S.
Show answer
A. Pilot's Operating Handbook or UAS Flight Manual
Weight and balance limits are set by the manufacturer or builder and found in the aircraft's operating handbook or flight manual.

An aircraft stalls at 50 knots in level flight. At about what speed could it stall in a maneuver producing 4 Gs?
- A100 knots
- B200 knots
- C54 knots
Show answer
A. 100 knots
Stall speed increases in proportion to the square root of the load factor. The square root of 4 is 2, so 50 × 2 = 100 knots.

(Refer to Figure 2.) A 20-pound unmanned airplane makes a level turn at 60° of bank. What load must its structure support?
- A20 pounds
- B30 pounds
- C40 pounds
Show answer
C. 40 pounds
In a level 60° bank the load factor is 2.0 Gs, so the structure supports 20 × 2 = 40 pounds.

(Refer to Figure 2.) About what load does a 10-pound unmanned airplane's structure carry in a level 45° banked turn?
- A10 pounds
- B14 pounds
- C20 pounds
Show answer
B. 14 pounds
The load factor at 45° is 1.414, so 10 × 1.414 ≈ 14 pounds.
Source: FAA-CT-8080-2H, Figure 2
(Refer to Figure 2.) A 5-pound unmanned airplane is flown in a level 70° banked turn. What load is imposed on its structure?
- AAbout 7 pounds
- BAbout 10 pounds
- CAbout 15 pounds
Show answer
C. About 15 pounds
The load factor at 70° is 2.923, so 5 × 2.923 ≈ 14.6, or about 15 pounds.
Source: FAA-CT-8080-2H, Figure 2
How does load factor change as bank angle increases in a level turn?
- AIt increases slowly and evenly at all bank angles
- BIt increases at a rapidly accelerating rate beyond about 45° to 50° of bank
- CIt decreases after 60° of bank
Show answer
B. It increases at a rapidly accelerating rate beyond about 45° to 50° of bank
Load factor rises gradually at first and then very rapidly past 45°–50°: 2 Gs at 60°, about 5.75 Gs at 80°, approaching infinity near 90°.

After adding a camera payload, you find the CG is outside the allowable limits. What should you do?
- AFly carefully at reduced speed
- BRelocate or remove weight until the CG is within limits before flight
- CFly only in calm winds
Show answer
B. Relocate or remove weight until the CG is within limits before flight
If the CG is not within limits after loading, or will not stay within limits in flight, relocate or shed weight before flight. A CG outside limits causes control difficulty.

Which is a typical effect of operating an aircraft above its maximum weight?
- AA shorter takeoff run
- BA reduced rate of climb and a higher stalling speed
- CImproved maneuverability
Show answer
B. A reduced rate of climb and a higher stalling speed
Excess weight means a longer takeoff, reduced rate and angle of climb, lower maximum altitude, shorter range, reduced maneuverability and a higher stalling speed.

If an aircraft is not properly loaded, the first indication of poor performance usually appears during
- Atakeoff
- Bcruise
- Clanding
Show answer
A. takeoff
An improperly loaded aircraft usually shows poor performance first during takeoff.

In stabilized level flight, how does lift compare to weight?
- ALift is greater than weight
- BLift equals weight
- CLift is less than weight
Show answer
B. Lift equals weight
When lift equals weight, the aircraft is in equilibrium. If lift is less than weight, vertical speed decreases; if greater, it increases.

When the center of gravity is forward of the center of pressure, the aircraft tends to
- Apitch nose up
- Bpitch nose down
- Croll to the left
Show answer
B. pitch nose down
Weight acts at the CG and lift at the center of pressure. With the CG ahead of the CP, the aircraft has a natural nose-down pitching tendency.

You plan a heavy-payload flight on a hot, humid afternoon at a high-elevation site. What should you consider?
- AReducing weight, because high density altitude reduces takeoff and climb performance
- BAdding weight to improve stability
- CNothing, because maximum takeoff weight is fixed regardless of conditions
Show answer
A. Reducing weight, because high density altitude reduces takeoff and climb performance
High elevation, high temperature and high humidity mean a high density altitude, which may require reducing weight before flight even below the published maximum.

The manufacturer of your small UA publishes no performance data. What does the FAA suggest?
- AFly without performance planning
- BUse performance data published by other users of the same model as a starting point
- CUse the data for the heaviest model on the market
Show answer
B. Use performance data published by other users of the same model as a starting point
If manufacturer data is unavailable, seek out performance data already determined and published by other users of the same model and use it as a starting point.

Your small UA releases a payload during flight. What should you anticipate?
- ANo change in handling
- BA change in weight that can shift the CG and affect balance
- CAn increase in stall speed
Show answer
B. A change in weight that can shift the CG and affect balance
Using expendable items or a jettisonable load changes weight during flight, which can shift the CG. Plan for how the CG will move and how the aircraft will respond.

Which force is the only one that counteracts weight and sustains an aircraft in flight?
- AThrust
- BLift
- CDrag
Show answer
B. Lift
Lift is the only force that counteracts weight. The lift produced is limited by airfoil design, angle of attack, airspeed and air density.

The center of gravity of a small UA is best described as
- Athe point at which all of the aircraft's weight is considered to be concentrated
- Ba fixed point marked by the manufacturer
- Cthe point where lift acts on the wing
Show answer
A. the point at which all of the aircraft's weight is considered to be concentrated
The CG is where the weight may be considered concentrated. It is not a fixed point: its location depends on how weight is distributed, and it shifts as loads move or are released.
Source: Remote Pilot Study Guide (FAA-G-8082-22), Ch. 4
Which statement about the center of gravity is correct?
- AIt never changes once the aircraft is built
- BIt only changes when the battery is replaced
- CIt moves when payload is added, moved or released
Show answer
C. It moves when payload is added, moved or released
Because the CG depends on weight distribution, shifting or expending variable load items moves it. The remote PIC should determine how it will shift and what that does to handling.

The ideas people miss most
- Multiply, don't add. The load factor is a multiplier: 33 pounds in a 30° bank is 33 × 1.154, about 38 pounds.
- Stall speed grows with the square root. At 2 G the stall speed rises by √2, about 41%, not 100%.
- Moving weight moves the CG. Adding, moving or releasing a payload changes the balance, not just the weight.
