I have a question about a pending Flight Review I'm about to do with a Mavic 2 Pro: I understand that there is a "Manual" operation required, and this would be achieved by putting the RPAS into ATTI or Attitude mode. However, there is also a CAR rule that says the aircraft may not be modified in any way that would alter the design approved by Transport Canada for safety. This appears to be a classic Catch-22. If I do the mod that allows ATTI mode on a Mavic, I alter the aircraft in a way that takes it off the Approved list! Help!!
