Scenario, hypothetical of course
Boss wants to take company airplane and camera crew, along with upteen lithium batteries, "power packs", backpack size stuff, etc etc on a trip in support of his daughters wedding. Airlines already said no to above camera crew due to batteries and stuff.
Airplane is not a Global Express or BBJ (size), it is cabin of a Citation II.
Boss says "his plane" is Part 91, so it is "not a problem."
Besides the PIC discretion regarding safety (while is probably gonna be a "no"), what regulations apply to this situation (lithium batteries). Is Part 91 truly exempt or what ?
Sorry in advance, my fluency in taking a boat-load of batteries and power packs is not the highest.
Thanks
