By now you probably know that BasicMed allows you to be PIC but not a safety pilot. But, there is a workaround that could get you in trouble with your insurance company.
When we got BasicMed, something wed done for a long time was taken away. BasicMed applies to acting as pilot in command. But, with BasicMed youre not legal to act as a safety pilot for your buddy whos under the hood practicing approaches in VMC. So, you exercise the workaround of agreeing ahead of time that you, the safety pilot, are indeed the PIC for this flight (more on that in a moment), then youre once again good to go even with BasicMed ... if, that is, the aircraft insurance agrees. Lets look more carefully at all this.
