Part 107 ACS Task Area 8: Aeronautical Decision-Making and Judgment

Aeronautical Decision-Making and Judgment is Task Area 8 of the Unmanned Aircraft General, Small (UAG) Airman Certification Standards (ACS). Every other task area on the Part 107 knowledge test gives you rules and numbers to memorize (altitude ceilings, airspace classes, weather minimums). This task area is different: it tests a decision-making process, not a fact set, because the FAA (Federal Aviation Administration) has found across decades of aviation safety data that most accidents trace back to a chain of small judgment errors rather than a single mechanical failure, and a remote pilot who never learns a structured way to catch that chain early is flying on luck.

What aeronautical decision-making actually is

Aeronautical decision-making (ADM) is a structured, repeatable process for recognizing a hazard, evaluating the risk it poses, and choosing a course of action, applied continuously through a flight rather than once during preflight planning. It exists because good stick-and-rudder skill (or, for a remote pilot, good hands-on control skill) does not by itself prevent accidents caused by flying into a situation you should have avoided in the first place. The ACS tests four specific ADM tools: the PAVE checklist, the five hazardous attitudes, the DECIDE model, and crew resource management (CRM).

The PAVE risk checklist

PAVE is a four-category framework for identifying risk before you launch, one letter per source of risk:

• Pilot. Your own fitness to fly: currency, experience with this type of operation, and physical or mental condition. See Task Area 7 for the fitness-for-duty standard this category draws on directly.
• Aircraft. The airworthiness of the specific drone you are about to fly: battery condition, firmware status, control-link health, and anything flagged during preflight inspection. See Task Area 10 for what a real preflight check covers.
• enVironment. Weather, airspace, terrain, and the people and property below your flight path, all of which can change between when you planned the flight and when you launch it.
• External pressures. Client deadlines, a long drive already made to the site, or a schedule that makes canceling feel more costly than it actually is. This is the category pilots most often underweight, because the pressure is real but the consequences of ignoring it are not visible until something goes wrong.

The five hazardous attitudes and their antidotes

FAA risk-management material identifies five recurring thought patterns that lead pilots into bad decisions, each paired with a specific corrective thought (the “antidote”) a pilot is taught to recognize and consciously substitute:

1. Anti-authority (“Don’t tell me.”) Antidote: follow the rules, they are usually right.
2. Impulsivity (“Do something quickly.”) Antidote: not so fast, think first.
3. Invulnerability (“It won’t happen to me.”) Antidote: it could happen to me.
4. Macho (“I can do it.”) Antidote: taking chances is foolish.
5. Resignation (“What’s the use?”) Antidote: I’m not helpless, I can make a difference.

Expect the test to describe a pilot’s internal reasoning in a scenario question and ask you to identify which hazardous attitude it demonstrates, or which antidote applies.

The DECIDE model

DECIDE is a six-step decision loop meant to be run continuously during a flight, not just once before takeoff: Detect a change or problem, Estimate its significance to safety, Choose a desired outcome, Identify the actions that achieve it, Do the necessary action, and Evaluate the effect of that action, which feeds back into detecting the next change. The loop repeating is the point: a single pass through DECIDE is not enough for a flight of any real duration, because conditions keep changing after you act.

Crew resource management for a one- or two-person crew

Crew resource management (CRM) is usually associated with airline flight decks, but the same principles apply to a remote pilot working with a visual observer (VO), and the ACS expects you to know how. Clear role separation matters: the VO’s job is to maintain visual contact with the aircraft and communicate hazards immediately, while the RPIC’s job is to fly and make the final call, and both roles fail if either person assumes the other is watching for something they are not. The most important CRM principle for a small crew is shared stop authority: either person, VO or RPIC, must be able to call for the flight to stop or the aircraft to land immediately, without waiting for permission, if they see something wrong. A crew where only the RPIC can call a halt has already lost the main safety benefit of flying with a second person.

How this gets tested

This task area is almost entirely scenario-based. Expect a short narrative describing a pilot’s situation, thought process, or crew interaction, followed by a question asking what the pilot should have done, which hazardous attitude is present, or which PAVE category the described risk falls under. There is very little pure recall here, which makes it one of the harder task areas to cram the night before a test. Work through scenario questions in the free practice bank until applying PAVE and the hazardous attitudes feels automatic rather than like a lookup exercise.
