Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated.

Conditions and concepts

Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated. LAANC processes eligible low-altitude airspace authorization requests; UAS Facility Map grid values are planning limits, not permission by themselves. Pilots must check applicable flight restrictions and avoid interfering with airport operations and traffic patterns; a base map is not a complete current briefing. An airspace authorization and a waiver of a waivable Part 107provision are distinct approvals; apply only within the actual granted scope.

Worked decisions

A proposed flight is in Class B airspace and no authorization has been obtained. Which statement fits? Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated. The supported result is Prior FAA authorization is required for the stated controlled airspace. A facility-map grid shows100 ft, but the operator has not received authorization. What is still needed for an operation requiring it? LAANC processes eligible low-altitude airspace authorization requests; UAS Facility Map grid values are planning limits, not permission by themselves. The supported result is An actual airspace authorization. A familiar flight site now has a temporary flight restriction. What should control the operation? Pilots must check applicable flight restrictions and avoid interfering with airport operations and traffic patterns; a base map is not a complete current briefing. The supported result is The current applicable restriction. A pilot obtains authorization for controlled airspace but plans an operation beyond visual line of sight without another approval. What distinction matters? An airspace authorization and a waiver of a waivable Part 107provision are distinct approvals; apply only within the actual granted scope. The supported result is Airspace authorization alone does not waive VLOS.

A change that matters

A proposed flight is in Class D airspace and no authorization has been obtained. Which statement fits? Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated. Here choose Prior FAA authorization is required for the stated controlled airspace. An operator receives a LAANC authorization with conditions. What governs the authorized operation? LAANC processes eligible low-altitude airspace authorization requests; UAS Facility Map grid values are planning limits, not permission by themselves. Here choose The granted authorization and its conditions. A small UAS mission would cause an approaching manned aircraft to alter course. Which action best fits the right-of-way duty? Pilots must check applicable flight restrictions and avoid interfering with airport operations and traffic patterns; a base map is not a complete current briefing. Here choose Yield and keep clear of the aircraft. A pilot holds a waiver for one specified operating provision. What must still be checked? An airspace authorization and a waiver of a waivable Part 107provision are distinct approvals; apply only within the actual granted scope. Here choose Other applicable rules and the waiver's conditions.

Transfer check and reasoning

A facility map shows100 ft while no actual authorization has been granted. What is the missing evidence? The actual authorization for the location, time, altitude and operation. The map supports planning but is not itself permission.

WORKED EXAMPLE

A proposed flight is in Class B airspace and no authorization has been obtained. Which statement fits?

  1. The relevant case condition is: A proposed flight is in Class B airspace and no authorization has been obtained.
  2. Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated.
  3. Therefore choose “Prior FAA authorization is required for the stated controlled airspace”. The alternatives must be tested against that same stated condition; an unrelated document, unit or approval cannot supply a missing requirement.
Answer: Prior FAA authorization is required for the stated controlled airspace
Compare the other answer choices
No controlled-airspace authorization is required solely because this isClass G

The proposed choice “No controlled-airspace authorization is required solely because this isClass G” does not follow from the given conditions. Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated.

A facility-map number alone is an authorization

The proposed choice “A facility-map number alone is an authorization” does not follow from the given conditions. Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated.

Property-owner consent replaces FAA authorization

The proposed choice “Property-owner consent replaces FAA authorization” does not follow from the given conditions. Part 107 operations in Class B, C, Dand surfaceClass E designated for an airport need the applicable prior ATC authorization; Class G is uncontrolled but still regulated.

Try it, then explain it.

Complete a short set without looking at the example. After each answer, explain which evidence or rule supports your decision and why the alternatives do not fit.
