Part 107 Practice Test

Part 107 Loading & Performance Practice Questions

Loading & Performance makes up 5 of every 50 questions on a Tigertest Part 107 practice test. Here are 10 of the 20 questions on it, each with the answer and the reason.

Updated 2026-11-10 by the Tigertest team. Weighted to the FAA Remote Pilot ACS. The real test adds sectional chart figures, so study a chart legend too.

1. 1. A remote PIC mounts a heavy camera at the nose of a fixed-wing sUAS, moving the CG ahead of the forward limit. What effect should be expected?

   • A.Reduced stability and difficult stall recovery
   • B.Higher stall speed and less elevator authority for landing
   • C.No effect if total weight stays below the maximum
   • D.Lower stall speed and a shorter landing roll

   Answer: B. A forward CG makes the aircraft nose-heavy, raising stall speed and requiring more elevator, which may be insufficient to flare. Reduced stability and poor stall recovery are aft-CG problems.

2. 2. What is the most dangerous effect of loading a fixed-wing sUAS with its center of gravity aft of the aft limit?

   • A.Longer endurance from reduced tail-down force, with no handling penalty
   • B.Heavier control forces and a steeper climb
   • C.Increased stability and a higher stall speed
   • D.Reduced stability and possible inability to recover from a stall

   Answer: D. An aft CG reduces longitudinal stability and can make stall or spin recovery impossible. Higher stall speed and heavier control forces are associated with a forward CG.

3. 3. A remote PIC loads a sUAS beyond the manufacturer's maximum takeoff weight to carry extra equipment. Which result should the PIC expect?

   • A.Reduced climb performance, reduced maneuverability, and shorter endurance
   • B.Longer flight time because inertia smooths power demand
   • C.Improved stability in gusts with no performance penalty
   • D.Lower stall speed from the added wing loading

   Answer: A. Exceeding maximum takeoff weight degrades climb rate, maneuverability and endurance, raises stall speed, and can overstress the structure. Weight never improves performance.

4. 4. In straight-and-level unaccelerated flight, which aerodynamic force directly opposes thrust?

   • A.Weight
   • B.Load factor
   • C.Drag
   • D.Lift

   Answer: C. Of the four forces, lift opposes weight and thrust opposes drag. In unaccelerated flight, thrust equals drag and lift equals weight.

5. 5. If a fixed-wing sUAS doubles its airspeed while angle of attack and air density stay the same, how does lift change?

   • A.It stays the same
   • B.It becomes about half as great
   • C.It becomes about four times as great
   • D.It roughly doubles, matching the change in airspeed

   Answer: C. Lift varies with the square of airspeed, so doubling airspeed produces about four times the lift. Lift also increases with angle of attack up to the critical angle.

6. 6. A fixed-wing sUAS wing will stall under which condition?

   • A.When it exceeds the critical angle of attack, at any airspeed
   • B.Only in a steep nose-up pitch attitude
   • C.When it reaches maximum takeoff weight in level flight
   • D.Only when airspeed drops below the published stall speed

   Answer: A. A wing stalls whenever it exceeds its critical angle of attack, regardless of airspeed, attitude or weight. Stall speed is only a reference for a given load factor and configuration.

7. 7. A fixed-wing sUAS holds a level, coordinated turn at a 60 degree bank angle. What load factor is it experiencing?

   • A.1.5 G
   • B.1 G
   • C.3 G
   • D.2 G

   Answer: D. Load factor in a level turn increases with bank angle, and a 60 degree bank produces 2 G. This doubles the load the wings must support.

8. 8. A 10 lb fixed-wing sUAS performs a level 60 degree banked turn. What total load must the wing support?

   • A.30 lb
   • B.20 lb
   • C.15 lb
   • D.10 lb

   Answer: B. A 60 degree bank produces a 2 G load factor, so the wing must support twice the aircraft's weight, or 20 lb. Higher loads also raise stall speed.

9. 9. A fixed-wing sUAS stalls at 20 knots in level flight. About what is its stall speed in a level 60 degree banked turn?

   • A.About 40 knots
   • B.About 28 knots
   • C.20 knots
   • D.About 24 knots

   Answer: B. Stall speed increases with the square root of load factor; at 2 G, the square root is about 1.41. 20 knots times 1.41 is about 28 knots.

10. 10. A multirotor that hovers for 25 minutes at sea level is flown at a high mountain site on a hot day. What should the remote PIC plan for?

    • A.Unchanged flight time, since batteries are unaffected by altitude
    • B.Lower motor RPM because there is less air resistance
    • C.Longer flight time because thin air reduces drag
    • D.Higher motor RPM and current, and noticeably shorter flight time

    Answer: D. High density altitude means less dense air, so propellers must spin faster to produce the same thrust. The higher current draw reduces flight time and leaves less power margin.
