When a remotely piloted aircraft is operating under scenarios S-1, S-2, or S-3, the operator must establish a third-party exclusion zone.<\/p>\n

This zone is used to keep people who are not involved in the mission away, to minimize the risks in the event of a crash or emergency landing.<\/p>\n

The operator must ensure that no third party enters the exclusion zones at any time during the flight.<\/p>\n

Who can be considered a third party?<\/u><\/strong>
\nA third party is a person who is not directly involved in the mission. Under no circumstances may these third parties enter the exclusion zone. <\/p>\n

The following are not considered third parties:
\n<\/strong>– persons involved in flying the aircraft (the remote pilot)
\n– people involved in operating mission equipment (such as the cameraman)
\n– people isolated by a safety<\/a> a device or structure that provides sufficient protection
\n– individuals directly involved in the specific activity who have signed a certificate (available by clicking here)<\/a> stipulating that they have been informed of the emergency procedures established by the operator in the event of an in-flight incident involving the aircraft (this may be the case, for example, at a wedding: the guests being photographed are not part of the mission, but in order to be photographed, they must agree to have the drone fly over them and therefore sign a statement).<\/p>\n

Scenario S-1:<\/u><\/strong>
\nIn the case of an aircraft used in Scenario S-1, the maximum third-party exclusion zone is a disk with a 30-meter radius<\/strong> centered on the aircraft’s projection on the ground.<\/p>\n

However, when the remote pilot has ground speed information, the 30-meter radius may be reduced(but never below 10 meters<\/strong>) if the remotely piloted aircraft is:
\n– an airship weighing < 8 kg
\n– an aerodyne equipped with a third-party protection device (parachute) weighing \u2264 8 kg
\n– an aerodyne weighing \u2264 2 kg when used at a height \u2264 50 meters<\/p>\n

In this case, the radius of the circle defining the third-party exclusion zone must be calculated using the following formula:
\n(source : JO n\u00b00298 du 24\/12\/2015<\/a>)<\/p>\n

In practice, this formula is difficult to implement. If you need to know this (especially for the exam), the Guide Drones: Guide Cat\u00e9gorie Sp\u00e9cifique<\/a> includes an appendix with tables listing R values based on the altitude and speed of the remotely piloted aircraft. These handy tables simplify mission planning. They are provided at the bottom of the page. <\/p>\n

Note that, in the case of scenario S-1, it is possible to move the third-party exclusion zone at the same time the unmanned aircraft is moving! However, caution is required: in the event of a loss of radio connection, the device must be properly configured so that it does not leave the exclusion zone. <\/p>\n

Scenario S-2:<\/u><\/strong>
\nIn the case of an aircraft used in Scenario S-2, the minimum exclusion zone for third parties is an area\u2014fixed for the entire duration of the flight<\/strong>\u2014corresponding to the ground projection of the maximum flight volume plus a horizontal safety margin of 30 meters<\/strong>.<\/p>\n

Unlike the S-1, the exclusion zone cannot be moved at the same time as the remotely piloted aircraft. It is therefore advisable to plan the flight route in advance so as to create a single exclusion zone that encompasses all of the drone’s possible maneuvers. <\/p>\n

Scenario S-3:<\/u><\/strong>
\nFor Scenario S-3, the procedure is very similar to that of Scenario S-1.
\nHowever, one requirement has been added:
\n– For tethered- >, 8 kg, and tethered-aerodynes weighing over 2 kg that are not equipped with a third-party protection device, a disk centered on the attachment point of the restraint device, with a radius equal to the maximum cable length expected during use, plus 5 meters.<\/p>\n

The formula and the way it is used therefore remain the same as in the S-1 scenario.<\/p>\n

Resources:<\/u><\/strong>
\nThere are many ways to mark out your route:
\n– use marker trestles
\n<\/p>\n

– marker tape:
\n<\/p>\n

– In the city center, you can contact the municipal police or security guards:<\/p>\n

In some cases, you’ll be able to use existing barriers: for example, you can use the fence surrounding a building that you need to fly over. However, it is still your responsibility to ensure that no third party enters this area, so don’t hesitate to put up signs! <\/p>\n

Summary tables:<\/u><\/strong>
\nHere are the summary tables to simplify the use of the formula shown above.
\nThey are taken from Appendix 7 of the Drones Guide: Specific Category Guide<\/a>.
\nOf course, you don\u2019t need to know them, but they will help you prepare for your missions.
