91.144 abnormally high barometric pressure

Asked by: 1588 views FAA Regulations

91.144(a) no person may operate an aircraft, or initiate a flight contrary to the requirements established by the administrator and published in the NOTAMS under this section.

does this mean you cannot fly if barometric pressure is above 31.00 without authorization (aka 91.144(b))? 

also, what does the NOTAMS part mean exactly?

    What 91.144(a) is saying is that if the barometric pressure is going to be at or above 31 inches of mercury, there WILL be a NOTAM outlining the requirements/restrictions to deal with that abnormal pressure and you have to follow whatever restrictions are in that NOTAM…unless you get a waiver for the purposes outlined in (b).
