So fly with P3D and will mainly be in the PMDG 737 or 747. I like to fly a lot of charter-type flights and am always looking for new destinations. My question is how do you determine if an airport is capable of supporting an aircraft of your size such as 737 or 747? I know some airports may have a long enough runway but may not have taxiways or parking spaces of a big enough size. For example I recently flew into Bar Harbor in the sim with the 737 BBJ and even though the runway is long enough it felt like there would bee enough room for parking.
Airports have standing NOTAMs/remarks that will list things such as maximum wingspan, surface weight bearing capacity, whether air carrier aircraft are allowed, and other limitations. airnav.com is a good site for this. There's also the more unscientific method of looking at FlightAware and seeing what types of aircraft fly into specific airports.
At BHB, a BBJ might need to PPR if they wanted to take off at gross weight (and would have issues anyway due to runway length), but should be ok otherwise.
