The FARs (or Federal Aviation Regulations) are the regulations imposed by the FAA on aviation within the United States.
Many questions make reference to FAR 23, or FAR 91 etc. What are each of these? Where can one lookup the text?
In the US the "Federal Aviation Regulations" (FARs) is shorthand for referring to Title 14 of the Code of Federal Regulations.
You can browse all sections of FARs at this link:
FAR 23, for example, covers airworthiness standards. § 23.25 regulates weight limits.
There are several sites on the web, but my favorite is the FAA's own Regulatory and Guidance Library at http://rgl.faa.gov/. If you click the Code of Federal Regulations link on their main page, you can look at current and historical regulations as well as preamble information, links to the dockets, NPRM's, and more. Just click on "By Part" under the "Current CFR" section, and you can browse through each section. If you then scroll down, you will find the two that you asked about:
Part 23 - AIRWORTHINESS STANDARDS: NORMAL, UTILITY, ACROBATIC, AND COMMUTER CATEGORY AIRPLANES
Part 91 - GENERAL OPERATING AND FLIGHT RULES
Click the arrow next to each part and it will show links to the full text of each regulation.
The site also includes the following databases:

Is there a Canadian law or regulation which requires me to have my Radiotelephone Operator's Restricted Certificate (Aeronautical) on-board the aircraft with me? This is what I've found so far... service only where the person holds an appropriate radio operator certificate [...] However, I can't find a regulation saying I need the piece of paper with me. An example of the wording Canada uses in its regulations to say that you need to actually have the document with you is at CARS 401.03 (1)(d) (regarding pilot licences): the person can produce the permit, licence or rating
For fun I want to build a flight simulator at home. What are my options from most basic toy environment to more realistic set-up. Great if you can give for each solution a basic indication of cost (software / hardware), and if appropriate the space needed.
From what I understand, whether or not a flight is classified as private or commercial in the eyes of US Customs and Border Patrol (CBP) has nothing to do with the Federal Aviation Regulations (FAR) flight rules that they are operating under. For instance, I understand that I can legally be operating under FAR Part 91 and still be a commercial flight in the eyes of CBP. What then is the determining factor?
Advisory Circular AC 61-136 which outlines the approval and limitations of flight training devices seems to contradict 14 CFR 61.57(c). To what extent can I use an AATD for instrument currency? In addition, to what extent can an AATD be used toward and instrument proficiency check (IPC)? Edit: I have located this document from the FAA Office of Aviation Safety that clarifies that AATDs and BATDs are governed by FAR 61.4(c) and are authorized for specific purposes and can be used in the same manner at a Flight Training Device instead of a Aviation Training Device as long as they have
Many larger airports (class Bravos) have a landing fee. What's the process for assessing and collecting the fees? How do these landing fees work with general aviation aircraft? Where can I find out what the fee will be? Is it published? How will I be charged the fee? (Pay before leaving the airport, bill sent to my home, etc.) Is the landing fee a flat rate or is it calculated based on aircraft weight or some other factor? I've heard that the landing fee is generally waived if you buy a few gallons of (overpriced) gas at an FBO, is that true? Example scenario: I offer to take a friend up
After answering this question on History.SE, I started to wonder if it would be possible to find out even more detail about the plane now that its serial number is known. I have no idea what kind of flight records the US Army Air Corps kept, however. I know most flight logs today are kept by pilot, but I imagine there would be some way to trace what pilots flew a particular plane. I have no idea if this is possible for USAAC trainer planes in the 1930s. Could I get access to these records? If so, how would I go about it? I'm mostly interested in seeing if I can find out more information
Where can I find nice flutter animations/videos (other than YouTube) to add to a presentation without violating Copyright regulations ? It can either be for wings as well as blade arrays. Are you aware of any OpenSource database on this topic ?
the AFD entry for airports we intend to visit (part of FAR 91.103's "become familiar with all available information" requirement), and to comply with any restrictions noted - typically things like "no touch-and-go landings", "Standard traffic pattern required of all aircraft", "Prior Permission Required for jet aircraft", etc. Aside from it being The Right Thing To Do, and avoiding the possibility of local fines/sanctions, are the remarks in the Airport/Facility Directory "regulatory" such as to require compliance, or are they advisory where compliance is encouraged but not mandatory?
This is what I know: $V_1$ is the takeoff airspeed after which the aircraft must take off, no matter what happens after $V_1$ has been reached. That's the easy part (I think). $V_R$ is the rotation airspeed Are there any other $V$-speeds? What I'm specifically curious about: Is $V_1$ related to runway length? Is there an absolute maximum $V_1$ for each aircraft type? If so, can it vary based on conditions (takeoff weight, density altitude, etc.) Are there circumstances where $V_1$ is higher than $V_R$? If so, does that mean that $V_1$ is never called on a normal takeoff
