A UAV mission doesn’t start when the drone takes off. Before the flight, there is a series of checks and operational steps that keep the mission running under controlled conditions.
From defining the route and checking the aircraft to flying the mission, returning to the operating point and closing out the flight, each stage has a clearly defined role.
How does a UAV mission start?
The first stage is defining the mission objective.
The operator decides what needs to be checked, which area has to be covered, which route will be flown, and what type of data needs to be collected.
Depending on the purpose, the mission can be a patrol, an inspection, a spot check, or a scheduled mission.
What is checked before takeoff?
Before any flight, everything relevant to flying the mission safely is checked:
- the condition of the aircraft;
- battery level;
- communication systems;
- the payload and sensors;
- the position and route of the mission;
- weather conditions;
- the airspace and any restrictions that apply;
- availability of the required infrastructure.
The mission is launched only once the conditions for operating are met.
Who approves the mission and who launches it?
Roles are set out in the operator’s operational procedures.
Depending on the type of operation, the people involved may have different responsibilities for preparing, checking, approving and flying the mission.
For a BVLOS or autonomous operation, these responsibilities are defined in the operational framework and in the approved procedures.
How is the route planned?
The route is defined in the planning and control platform. It can include:
- waypoints;
- patrol corridors or routes;
- altitudes;
- speeds;
- points of interest;
- sensor actions;
- turnaround points;
- completion conditions.
Planning has to take into account both the mission objective and the real operating conditions.
What happens at takeoff?
Once the checks are complete, the drone is launched according to the applicable procedure.
With an autonomous dock system, the takeoff sequence can be automated. On an onsite mission, the pilot carries out the takeoff.
Whatever the setup, the operator must be able to monitor how the mission is being flown.
What does the operator watch during the flight?
The operator mainly follows four categories of information:
- Aircraft position: where the drone is relative to the planned route.
- Aircraft status: battery, communications, systems and other available data.
- The mission: progress along the route and completion of the set objectives.
- Sensor data: video, thermal imaging or other information collected.
Does the drone always fly exactly the planned route?
Not necessarily. The route is the initial plan for the mission, but the operator may need to react to what they see during the flight.
Depending on the system configuration and the operational procedures, the mission can be adjusted, interrupted or redirected when the situation calls for it.
When does the operator step in?
The operator steps in when a decision or action is needed that can’t be left to automation alone. For example, when:
- something unexpected happens;
- an area of interest is identified;
- operating conditions change;
- the mission has to be interrupted;
- an additional point needs to be checked.
The purpose of automation is to cut down repetitive work, not to remove the operator’s role.
What happens if something unexpected comes up?
Every operation must have procedures for abnormal and emergency situations. Depending on the situation, these can include:
- returning to a preset point;
- interrupting the mission;
- changing the route;
- handling a loss of communications;
- landing at a point defined in the procedures.
The exact action depends on the aircraft configuration and the procedures approved for the operation.
How does the mission end?
At the end of the route, the drone returns to the operating point or to the dock.
On an onsite mission, the pilot completes the flight and recovers the aircraft. With an autonomous system, the drone can return to the dock automatically, where it is prepared for the next mission.
What happens to the data collected?
The data collected during the mission can be used to analyze and document the result. Depending on the type of mission, it can include:
- photos;
- video;
- thermal images;
- telemetry;
- GPS positions;
- mapping data;
- other information generated by the payload.
The data can be analyzed during the mission or afterwards, depending on the objective of the operation.
Is a report generated after every mission?
Depending on the type of service, the mission can be closed by recording and documenting the result. Where relevant, the report can include information on:
- the date and duration of the flight;
- the area covered;
- the route flown;
- the data collected;
- the events or anomalies identified;
- the outcome of the mission.
The level of reporting is set according to the requirements of the operation and of the client.
What happens after the drone returns?
With a dock system, the aircraft can go straight into charging and stay ready for the next mission.
For onsite operations, the team carries out the post-flight checks and prepares the equipment for the next mission.
So the end of one flight is also the start of preparing for the next.
Can a mission be scheduled in advance?
Yes. Repetitive missions can be scheduled for certain intervals or times of day. This is useful for activities such as:
- perimeter patrols;
- infrastructure monitoring;
- periodic checks;
- repeat inspections;
- standardized data collection.
What is the difference between a manual and an automated mission?
In a manual mission, the pilot controls the aircraft directly for the whole flight.
In an automated mission, the route and certain actions are carried out by the system, based on parameters set beforehand.
In both cases, the mission has to be prepared, monitored and flown according to the applicable procedures.
Why does a standardized operational workflow matter?
A standardized process means missions can be flown in a repeatable, controlled way.
Standardization matters both for safety and for the quality and comparability of the data collected.
In short
When does a mission start?
It starts with defining the objective and planning the operation, not with takeoff.
What is checked before the flight?
The aircraft, battery, communications, sensors, route, weather and operating conditions.
Who monitors the mission?
The operator, through the control and monitoring system.
Can the route be changed during the flight?
Yes, when the system configuration and operational procedures allow it.
What happens at the end?
The drone returns to the operating point or to the dock, and the data collected is recorded and analyzed.
Can the mission be scheduled automatically?
Yes, with systems that allow missions to be planned and flown automatically.
Why do we need standardized procedures?
So that every mission is flown in a controlled, repeatable, and documented way.
