Medium level of robustness

M1B.C1.M.I

Criterion 1- Evaluation of people at risk

The applicant must provide space-time based restrictions (e.g., flying over a market square when it is not crowded) to substantiate that the actual density of people during the operation is lower than the iGRC. This must be done by:

(a) An analysis or appraisal of characteristics of the location and time of operation.

And/or.

(b) Use of temporal density data (e.g., data from a supplemental data service provider) relevant for the proposed area. This may incorporate real time or historical data.

M1B.C2.M.I

Criterion 2 – Impact on at risk population

The at-risk population must be lowered by at least 1 iGRC population band (~90%) using one or more methods described in the Level of Integrity for Criterion 1 above.

M1B.C1.M.A

Criterion 1- Evaluation of people at risk

The applicant must provide compliance evidence of the data sources and processes used to claim lowering the density of population at risk.

M1B.C2.M.A

Criterion 2 – Impact of at-risk population

The applicant must provide compliance evidence that the required level of integrity is achieved. This is typically achieved by means of analysis, simulation, surveys or through operational experience.

High level of robustness

Lower robustness level requirements to be complied with:

• M1B.C1.M.I

• M1B.C2.M.I

• M1B.C1.M.A

• M1B.C2.M.A

Additional requirements to be compiled with:

M1B.C1.H.I

Criterion 1- Evaluation of people at risk

No additional requirements.

M1B.C2.H.I

Criterion 2 – Impact on population

The at-risk population must be lowered by at least 2 iGRC population bands (~99%) using one or more methods described in the Level of Integrity for Criterion 1 above.

M1B.C1.H.A

Criterion 1- Evaluation of people at risk

No additional requirements

M1B.C2.H.A

Criterion 2 – Impact on population

No additional requirements

 

GM1 Article 11 Annex B. M1B Strategic mitigation using operational restrictions

CAA ORS9 Decision No. 46

GM.M1B

M1(B) mitigations are intended to reduce the number of people at risk on the ground independently of sheltering. These mitigations are applied pre-flight.

GM.M1B.C1.M.I

Characteristics of the location should be understood as land use that relates to the presence of people, e.g., industrial area, urban park, or shopping centres. Time should be understood as time of day or day of the week that would influence the presence of people, e.g., weekend for industrial plants, night-time, time after opening hours of shops.
