A certificate of waiver under §107.200 may authorize a deviation only from a regulation listed in §107.205, and only when the Administrator finds the operation can be conducted safely under the waiver's terms. The remote pilot certificate requirement in §107.12 is not on that list. Operating one small unmanned aircraft at a time (§107.35), visual line of sight (§107.31), and the operating limits in §107.51 are on the list. A normal Part 107 flight in Class D airspace needs an airspace authorization under §107.41, not a waiver.
What §107.205 actually names
The waiver list is specific. It includes operation from a moving vehicle or aircraft (§107.25); the anti-collision light required at night and during civil twilight (§107.29(a)(2) and (b)); visual line of sight (§107.31); the visual observer rules (§107.33); operation of more than one small unmanned aircraft (§107.35); yielding the right of way (§107.37(a)); operation over people (§107.39); operation in certain airspace (§107.41); the operating limitations in §107.51; and operations over moving vehicles (§107.145).
Two sentences on that list limit what the FAA will issue. Section 107.205(a) says no waiver of the moving-vehicle rule will be issued to allow the carriage of property of another by aircraft for compensation or hire. Section 107.205(c) says the same thing about a waiver of visual line of sight. Those sentences do not add a new waivable operation. They refuse a waiver of §107.25 or §107.31 when the purpose is carriage of someone else's property for compensation or hire.
The certificate is the item that cannot be waived. Asked which requirement can never be waived, the answer is the requirement to hold a remote pilot certificate. The 100 mph groundspeed limit is a §107.51 limit, and §107.51 is waivable. Visual line of sight is waivable, and a waiver of §107.31 is the current path for beyond visual line of sight. The night-training condition in §107.29(a)(1) is also absent from the list. Only the anti-collision light portion of the night rule is waivable. Who must hold the certificate is covered on the remote pilot in command page.
A routine Class D flight uses an authorization
A remote pilot plans a daytime, visual-line-of-sight photography flight at 200 feet above ground level inside Class D airspace, and every Part 107 operating rule will be followed. The pilot needs an airspace authorization under §107.41 before flying. LAANC is the routine way to request one. A certificate of waiver aimed at §107.41 is not the tool for ordinary controlled-airspace entry. Following the other operating rules does not remove the authorization.
Section 107.41 does appear in §107.205(h). That listing is a possible deviation from the airspace rule in an unusual case. It is not the permission a normal Class D flight uses. The normal flight complies with §107.41 by getting the authorization. Asking for a waiver, or asking for both a waiver and an authorization, treats a routine flight as a rule deviation. How authorizations differ from waivers, including where an application goes, is on the waivers and authorizations page. This page does not repeat the application contents.
Beyond visual line of sight through Class C needs both
An energy company plans a beyond-visual-line-of-sight powerline patrol that passes through Class C airspace. The operation needs a waiver of §107.31 for the beyond-visual-line-of-sight portion and an airspace authorization under §107.41 for the Class C segment. The visual-line-of-sight waiver does not authorize entry into Class C. The airspace authorization does not waive the requirement to see the aircraft. There is no infrastructure exemption that removes both approvals because the work is a powerline patrol.
The same pairing shows up anywhere a waivable deviation and controlled airspace occupy one flight. One remote pilot operating several aircraft needs a waiver of §107.35 if that operation will happen at all. If that flight also enters Class C, the airspace authorization is additional. A survey that needs more than 400 feet over open terrain, with no structure to use the §107.51 exception, is a waiver of §107.51, not a self-granted altitude.
The trap the items are built to catch
The certificate feels like paperwork, so it gets treated as waivable, while speed and visual line of sight feel absolute, so they get treated as permanent. The list is the opposite on all three. Section 107.12 stays. Sections 107.31, 107.35, and 107.51 can be waived when the safety case supports it, except that a visual-line-of-sight waiver will not be issued to carry another person's property for compensation or hire.
The airspace trap runs the other direction. Because §107.41 is printed on the waiver list, a normal Class D photo flight gets filed as a waiver. File the authorization. Save the waiver for a real deviation, and when the route is beyond visual line of sight inside Class C, obtain both.
