In plain language

If weather or other conditions make it impossible to test a specific flight variable during your drone exam, your instructor must have you complete a computer simulation or give a detailed oral explanation instead, and document why the live test was not possible.

Requirement as structured

If operating conditions prevent the demonstration of a flight variable during an innovative RPA assessment, the instructor must require the applicant to complete a computer simulation or provide a detailed oral explanation, and certify the exception in writing.

Original regulatory text

If a variable was not selected for demonstration because operating conditions made it impossible in practice to demonstrate the variable, the RePL training instructor must: (a) require the applicant to provide: (i) a satisfactory computerised simulation of the flight characteristics of the RPA... or (ii) a detailed oral explanation of the variable... and (b) certify in writing to the RePL training organisation... that: (i) operating conditions made it impossible in practice to demonstrate the variable
