As we all know, it's not only necessary to comply with minimum fuel requirements for your aircraft to complete the flight... in the "unpublished FAR/AIM" it clearly states "PIC should have enough coffee to complete the flight plus 30 minutes of extra caffeine during the day and 45 minutes of extra caffeine at night" Now staying within regs it's easier than ever, all thanks to these custom stainless steel travel mugs. Each mug holds 14 oz. of your favorite pilot's fuel. With a glossy white enamel finish, a spill-proof and screw-on cap, as well as a lined-in insulating plastic.
