Justification for Deviating Computations

In plain language

If you use your own custom calculations instead of the standard formulas to define your flight geography, contingency volume, or ground risk buffer, you must provide clear proof and documentation to justify them.

Requirement as structured

UAS operators who submit flight volume computations that deviate from the standard formulas must provide sufficient justification and documentation.

Original regulatory text

If you submit deviating computations, please ensure that there is sufficient justification and documentation.
