What happens if the center of gravity is too far aft?

The aircraft becomes less stable, controls feel very light and stall recovery gets harder.

Who is responsible for weight and balance on a Part 107 flight?

The remote pilot in command, who must check performance and loading before every flight and follow the manufacturer's instructions.

Part 107 Loading and Performance — Area IV — weight, balance and performance, 2% of the test

Loading and Performance is the smallest Area — 2% of the test, usually a single question. It checks that you understand how weight, balance and maneuvering loads change what your drone can do.

What the FAA tests in Area IV

The knowledge elements of the Airman Certification Standards (FAA-S-ACS-10B) for Loading and Performance. The FAA weighs this Area at 2% of the test since September 29, 2025.

General loading and performance: effects of loading changes
Balance, stability and center of gravity
The importance and use of performance data to calculate the effect on the aircraft's performance

In the Admezo bank: 1 topics, 3 questions

A. Loading and Performance

Key facts to know

PHAK ch. 10: Overloading increases takeoff distance and stall speed and reduces climb rate, range, speed and maneuverability.
Remote Pilot Study Guide: Load factor increases in any maneuver other than straight-and-level flight: about 2 G in a 60° level turn.
Remote Pilot Study Guide: Stall speed increases with the square root of the load factor: a 50-knot stall becomes 100 knots at 4 G.
14 CFR 107.49(e): Payloads must be secured and must not adversely affect the flight characteristics or controllability of the aircraft.

From the Admezo bank for Loading and Performance, outside the 20 free questions, as they appear in the app once answered — with the rule and a link to the official source. Rules checked October 27, 2026.

1 / 3IVMultiple choiceIV. Loading and Performance — A. Loading and Performance
I add a heavier camera to my drone, still within its limits. What effect should I expect?
- Reduced climb performance and shorter flight endurance (correct answer)
- Better stability in gusts and longer battery endurance
- No effect, because multirotor performance is weight-independent
Correct answer: A
Added weight increases the power required, which reduces climb performance and maneuverability and shortens range (PHAK p. 10-2; Study Guide p. 33). On a battery-powered drone, this higher power demand also shortens flight time.

2 / 3IVMultiple choiceIV. Loading and Performance — A. Loading and Performance
My fixed-wing drone stalls at 30 knots in level flight. In a maneuver producing a load factor of 4, what is its stall speed?
- 34 knots
- 60 knots (correct answer)
- 120 knots
Correct answer: B
Stall speed increases with the square root of the load factor: the square root of 4 is 2, so 30 knots becomes 60 knots (Study Guide, Load Factors and Stalls).

3 / 3IVMultiple choiceIV. Loading and Performance — A. Loading and Performance
The maker of my fixed-wing drone publishes no performance data. Where does the Remote Pilot Study Guide suggest starting?
- With the generic charts found in the appendix of Part 107
- With the performance tables printed in the AIM
- With data published by other users of the same model (correct answer)
Correct answer: C
Manufacturer performance data for small UA are not standardized; when none is available, data published by other users of the same model is a starting point (Study Guide, Determining Performance).

How to prepare for Loading & Performance

Study tips, not a promise: Admezo doesn't guarantee a result beyond its pass guarantee.

Learn three relationships
Weight versus performance, center of gravity versus stability, bank angle versus load factor. Almost every question in this Area tests one of them.
Read the load factor chart once
The testing supplement includes a load factor chart. Know how to read it; you may see it on test day.
Keep it short
One question on average: an hour of review is enough. Make sure it's a sure point, then move on.
