A sectional is a standing picture. A NOTAM is how that picture changes today. Part 107 points at both. Section 107.49 says the remote pilot in command, before flight, assesses the operating environment, including local airspace and any flight restrictions. Section 107.47 says the remote pilot must comply with §§91.137 through 91.145 and §99.7 of 14 CFR. Those sections are the temporary flight restriction and national-security airspace rules that are published by NOTAM.
What you are looking for
Temporary flight restrictions cover hazards, disasters, VIP movement, stadiums and major sporting events, and security-sensitive airspace. The chart does not update when a wildfire TFR goes up this morning. The NOTAM does. Stadium restrictions and §99.7 security airspace are the reason "I checked the sectional last month" is not a preflight.
Section 107.47 incorporates the temporary-flight-restriction rules in §§91.137 through 91.145 and the security airspace in §99.7. Those notices can appear the morning of the flight. A stadium event, a disaster area, or a security restriction does not have to be printed on the sectional you studied last month.
The ACS specifically expects you to know that an established NOTAM briefing is available from Flight Service. Call 1-800-WX-BRIEF or use 1800wxbrief.com, and ask for the NOTAMs relevant to the operation. A PDF of a sectional saved on a tablet is not that briefing. Assuming no NOTAM applies to small unmanned aircraft is not that briefing either.
The course is careful about one sentence students over-read. A NOTAM is not automatically required to exist for every UAS operation unless the authorization or waiver says the operation itself must be NOTAMed. You can fly a legal Part 107 flight in Class G with no NOTAM filed about you. You still look up the NOTAMs that other people have filed, because one of them may restrict the airspace you wanted.
Chart notes that point at NOTAMs
Some sectionals tell you the chart is incomplete on purpose. FAA-CT-8080-2H Figure 22, the Coeur d'Alene excerpt, prints a note to see NOTAMs and the directory for the effective hours of Class E at the surface. The directory is the Chart Supplement. While that surface Class E is in effect, you need prior ATC authorization under §107.41. When it is not in effect, the surface is Class G, up to the overlying Class E floor. Near Coeur d'Alene that floor is the 700-foot magenta vignette. The note is not itself a LAANC approval. It is an instruction to go check.
Part-time Class D and part-time towers work the same way. The star on the airport symbol means "look up the hours," not "the tower is closed."
Special-use airspace and TFRs are different layers
A restricted area has published times and a controlling agency. A TFR can cover a town that has no restricted area at all. Clearing one does not clear the other. Military Operations Areas and restricted areas are charted special-use airspace, covered on the MOA and restricted area page. A TFR is temporary even when the reason, such as a major sporting event, happens on a schedule. Read the NOTAM text for the radius, the altitude, and the times. The chart, the Chart Users' Guide notes, depicts only certain security-related TFRs. The rest exist only in the notice.
Where this sits in the preflight
Weather, NOTAMs, and the aircraft manual are separate resources. A clear TAF does not cancel a TFR. A LAANC approval does not cancel one either. If you are the remote pilot, you are the person §107.47 applies to. Delegating the tap on a consumer map, without knowing what source it used and how fresh it is, does not move the duty. Use an official briefing, then fly inside what it allows.
