Chapter 22 of 23
Integrated Mission Planning and Operational Risk Control
Real exam scenarios combine airspace, weather, loading, regulations, and human factors in a single question. A complete planning workflow teaches learners to identify the controlling rule and choose the safest legally defensible answer.
1. Start With the Mission, Then Find the Controlling Rule
Translate the Request
Convert "film a sunset roof inspection near downtown" into aircraft, location, altitude, time, people, route, weather, and airspace questions. One request can trigger several rules at once.
Basic Part 107 Pathway
A small unmanned aircraft is "An unmanned aircraft weighing less than 55 pounds on takeoff, including everything that is on board or otherwise attached to the aircraft."
Find What Controls
Check registration, Remote ID, pilot eligibility, airspace, weather, people, and loading. The most restrictive applicable rule controls the plan, even if every other factor is acceptable.
Redesign Before You Waive
A waiver is not an instant workaround. Often the safest legal solution is a different time, location, route, altitude, or operational zone.
2. Build the Regulatory and Airspace Gate
Registration Is Not Remote ID
Part 107 aircraft must be registered and externally marked with the registration number. Registration and Remote ID are separate checks; completing one does not prove compliance with the other.
Remote ID Types
The Types of Remote Identification under 14 CFR part 89 are: 1. Standard remote identification 2. Alternative remote identification
Controlled Airspace
Class B, C, D, and Class E surface areas require prior FAA authorization. Class G does not. A UAS Facility Map supports planning but is not authorization.
Altitude Logic
The normal ceiling is 400 feet AGL. Near a structure, operation may be higher only while remaining within 400 feet of that structure's uppermost limit.
3. Worked Site Survey: Downtown Roof at Dusk
Map the Exact Point
A hotel near an airport may sit in controlled airspace even when the pilot plans a low flight. Plot the launch and work area, then identify the actual airspace class and airport relationship.
Map Values Are Planning Data
Compare UAS Facility Map values with roof height and needed clearance. The map is not authorization; authorization limits still control the operation.
Use the Structure Exception Precisely
A 220-foot roof could allow flight up to 620 feet AGL only while within 400 feet of its uppermost limit and only if airspace authorization permits it. Fly lower if lower completes the task.
Site Control at Dusk
Control the adjacent sidewalk, identify cranes and rooftop obstacles, and plan for darkness. Night operations require anti-collision lighting visible for at least 3 statute miles.
4. Combine Weather, Loading, and Performance
Legal Minimums
Part 107 requires 3 statute miles visibility from the control station, 500 feet below clouds, and 2,000 feet horizontally from clouds. These minimums are not automatically safe operating conditions.
Read the Whole Weather Picture
Use METAR for current conditions and TAF for the mission window. Then assess local effects: rooftop turbulence, channeling between buildings, fog pockets, and hidden wind gradients.
Density Altitude and Payload
Heat, elevation, humidity, payload, and battery mass reduce performance margin. Wind raises power demand and can make the return leg much more demanding than the outbound leg.
Battery Is a Contingency Resource
Plan energy for transit, task time, return against likely wind, and an abnormal landing or diversion. Published wind resistance does not guarantee a safe mission.
5. Decision Exercise: Is the Weather Good Enough?
Make the call
A planned mapping mission is in Class G airspace. The METAR reports 4 statute miles visibility, scattered clouds at 1,200 feet AGL, wind 16 knots gusting 24 knots, temperature 34 C, and no precipitation. The manufacturer's guidance lists a 22-knot maximum wind resistance. The aircraft is carrying its heaviest approved mapping payload. The route requires a 0.8-mile outbound leg, several minutes of crosswind passes, and a return that may be directly into the wind.
Pause and identify three facts:
- Which facts establish that the basic Part 107 visibility and cloud-clearance rules can be met?
- Which facts create a performance concern even though no specific Part 107 wind maximum is exceeded?
- What objective criterion would you add before launch?
Suggested analysis
The reported visibility exceeds 3 statute miles, and the cloud base permits a low-altitude operation that stays 500 feet below clouds and 2,000 feet horizontally away. But the gusts exceed the manufacturer's stated wind-resistance figure, and high temperature plus maximum payload reduce hover, climb, and battery margin. A prudent plan is no launch until on-site wind measurement and a conservative battery-performance check show conditions within the aircraft's limits. If launched after conditions improve, define a continuation trigger such as: abort the mapping pattern if sustained wind or gusts exceed the selected limit, if ground speed on the return-heading test is inadequate, or if projected landing reserve falls below the mission reserve.
The key distinction: regulatory minimum weather may be met while the mission remains operationally unacceptable.
6. Assign the Crew Without Giving Away PIC Authority
One Final Authority
The remote PIC must be designated and is directly responsible for and the final authority over the small UAS operation. More crew members do not divide that authority.
Control Manipulator
A person manipulating the controls flies under the remote PIC's direction. They can identify danger and make an immediate safety maneuver, but they do not replace the remote PIC.
Observer and Ground Support
A visual observer scans aircraft and hazards using concise callouts. Ground support manages batteries and site access. Neither role should create unnecessary distraction during critical phases.
Customer Is Not the PIC
A customer can identify the desired result, but cannot compel an unsafe or noncompliant flight. Brief communication failures, stop-work calls, and emergency actions before launch.
7. Turn Hazards Into an Operational Risk Register
A Risk Register Must Be Specific
For every hazard, record initial risk, mitigation, residual risk, trigger, and owner. "Use caution" is not a mitigation because it does not state an action or who will take it.
Example: Pedestrians
A sidewalk hazard can be mitigated with cones, a ground-support person, and a rerouted flight path. The trigger is clear: anyone entering the buffer causes a hold or abort.
Residual Risk Remains
Controls reduce risk; they rarely erase it. A mitigation is credible only if the crew can perform it despite workload, noise, changing weather, and time pressure.
Phase-Based Criteria
Set separate launch, continuation, abort, and recovery criteria. A sound plan defines safe options before the aircraft is airborne.
8. Quiz: Airspace and Altitude
Choose the most accurate answer. Focus on the difference between planning information, FAA authorization, and the structure-based altitude provision.
A remote PIC plans to inspect a 300-foot building in controlled airspace. A UAS Facility Map depicts an altitude value that appears usable. Which action is required before relying on that map value for the operation?
- Obtain the required FAA airspace authorization and comply with its conditions; the map alone is not authorization.
- Fly without authorization because inspection work is within 400 feet of a structure.
- Fly only below the building roof because UAS Facility Maps automatically authorize low-altitude flight.
- Request a Part 107 waiver because all controlled-airspace operations require a waiver.
Show Answer
Answer: A) Obtain the required FAA airspace authorization and comply with its conditions; the map alone is not authorization.
UAS Facility Maps support planning and may inform available authorization altitudes, but they are not authorizations. Controlled-airspace operations require prior FAA authorization. The 400-feet-of-a-structure provision affects the Part 107 altitude limit; it does not remove controlled-airspace authorization requirements. A waiver and an airspace authorization are different regulatory tools.
9. Brief, Fly, Recover, and Report
Brief for Shared Action
Confirm mission boundaries, authorization, weather, altitude, crew positions, communications, operational zone, emergency landing areas, battery reserve, and abort calls. Seek positive acknowledgement from every crewmember.
VLOS Is an Active Duty
Visual line of sight means unaided vision, except corrective lenses, is used to know location, attitude, altitude, direction, hazards, and whether the aircraft endangers life or property.
Postflight Inspection
After landing, inspect the airframe, propellers, motors, payload, and batteries. Isolate damaged batteries, record discrepancies, and escalate maintenance before the next operation.
FAA Reporting Trigger
Under 14 CFR 107.9, report within 10 days a serious injury, loss of consciousness, or qualifying property damage of at least $500, excluding damage to the small unmanned aircraft.
10. Flashcards: Integrated Planning Recall
Flip each card, answer aloud, then connect the term to a planning decision.
- What is the first planning task?
- Translate the request into a specific operation: aircraft, location, time, altitude, route, people, airspace, weather, payload, and crew.
- UAS Facility Map
- A planning tool showing altitude information used to support airspace planning. It is not, by itself, FAA airspace authorization.
- Part 107 basic weather minimums
- At least 3 statute miles visibility from the control station, at least 500 feet below clouds, and at least 2,000 feet horizontally from clouds.
- Remote PIC
- A remote pilot in command must be designated before or during the flight of the small unmanned aircraft. The remote pilot in command is directly responsible for and is the final authority as to the operation of the small unmanned aircraft system.
- Residual risk
- The risk that remains after planned controls or mitigations are applied.
- Abort criterion
- A preplanned, objective condition that requires stopping the task and transitioning to a safe recovery action.
- FAA accident reporting under 14 CFR 107.9
- Report to the FAA within 10 days if an operation causes serious injury, loss of consciousness, or qualifying property damage of at least $500, excluding damage to the small unmanned aircraft.
11. Quiz: The Safest Legally Defensible Decision
This scenario combines crew, weather, and ground risk. Select the action that best follows the integrated planning workflow.
During a planned night facade inspection, the visual observer reports pedestrians entering the planned buffer zone. Wind gusts have risen to the remote PIC's prebriefed abort limit, and the aircraft has enough battery to return. The customer asks the control manipulator to finish one last camera pass. What should happen?
- The remote PIC should abort the task and recover using the planned safe landing procedure.
- The control manipulator should finish the pass because the customer requested it and battery is adequate.
- The visual observer should take command because pedestrians are the primary issue.
- Continue only if the aircraft remains below the roofline and the customer moves farther away.
Show Answer
Answer: A) The remote PIC should abort the task and recover using the planned safe landing procedure.
Two objective abort triggers have occurred: people have entered the protected area and gusts have reached the prebriefed limit. The remote PIC retains final authority and should stop the task and recover safely. Adequate battery does not erase the risk, and neither the customer nor the visual observer takes over the remote PIC's authority.
