Narrative:

I was giving rides to friends from ZZZ mostly to the west, clear of airspace at ZZZ1 airport. WX was starting to go MVFR west so I started maneuvering more north of ZZZ than expected at 7500 to 8500 ft MSL. I was squawking 1200 with no flight following. I noted on my WAC and GPS that I was nearing P40, and I believed that I could be at 7500 to 8500 ft and not be in their airspace. I was flying and checking the map, I did not see the R4009 in-flight. I was approaching ZZZ and was asked to 'identify' by someone and I did. I was then told to contact ZZZ2 approach for possible airspace violation. I thought the reason was that I 'clipped ZZZ1 airspace, but looked at my track and saw I was ok.' I called approach and was told that I violated P40 and that the supervisor would 'file a pilot deviation with FSDO.' I was unaware of the NOTAM expanding the prohibited airspace. As such a major NOTAM, I feel it worthy of issuing new second/WAC charts and outline the no fly zone in red hash marks when it is surface to class a airspace. I believe the FAA should also have a website with all no fly zones clearly depicted on a USA interactive map with a red DOT. I could then click the 'red DOT' and see an exploded view (map) and read the NOTAM details -- none exists as I know of. In the last month, I have flown with clearance into many class B airspaces properly. I believe better reporting of NOTAM with pictures (and new maps) would better help me than any other 'remedial' training that may result because of this.

Title: GA PLT OBSERVED OVER FLYING P40, CHALLENGED AND INTERVIEWED BY FAA.

Narrative: I WAS GIVING RIDES TO FRIENDS FROM ZZZ MOSTLY TO THE W, CLR OF AIRSPACE AT ZZZ1 ARPT. WX WAS STARTING TO GO MVFR W SO I STARTED MANEUVERING MORE N OF ZZZ THAN EXPECTED AT 7500 TO 8500 FT MSL. I WAS SQUAWKING 1200 WITH NO FLT FOLLOWING. I NOTED ON MY WAC AND GPS THAT I WAS NEARING P40, AND I BELIEVED THAT I COULD BE AT 7500 TO 8500 FT AND NOT BE IN THEIR AIRSPACE. I WAS FLYING AND CHKING THE MAP, I DID NOT SEE THE R4009 INFLT. I WAS APCHING ZZZ AND WAS ASKED TO 'IDENT' BY SOMEONE AND I DID. I WAS THEN TOLD TO CONTACT ZZZ2 APCH FOR POSSIBLE AIRSPACE VIOLATION. I THOUGHT THE REASON WAS THAT I 'CLIPPED ZZZ1 AIRSPACE, BUT LOOKED AT MY TRACK AND SAW I WAS OK.' I CALLED APCH AND WAS TOLD THAT I VIOLATED P40 AND THAT THE SUPVR WOULD 'FILE A PLT DEVIATION WITH FSDO.' I WAS UNAWARE OF THE NOTAM EXPANDING THE PROHIBITED AIRSPACE. AS SUCH A MAJOR NOTAM, I FEEL IT WORTHY OF ISSUING NEW SEC/WAC CHARTS AND OUTLINE THE NO FLY ZONE IN RED HASH MARKS WHEN IT IS SURFACE TO CLASS A AIRSPACE. I BELIEVE THE FAA SHOULD ALSO HAVE A WEBSITE WITH ALL NO FLY ZONES CLEARLY DEPICTED ON A USA INTERACTIVE MAP WITH A RED DOT. I COULD THEN CLICK THE 'RED DOT' AND SEE AN EXPLODED VIEW (MAP) AND READ THE NOTAM DETAILS -- NONE EXISTS AS I KNOW OF. IN THE LAST MONTH, I HAVE FLOWN WITH CLRNC INTO MANY CLASS B AIRSPACES PROPERLY. I BELIEVE BETTER REPORTING OF NOTAM WITH PICTURES (AND NEW MAPS) WOULD BETTER HELP ME THAN ANY OTHER 'REMEDIAL' TRAINING THAT MAY RESULT BECAUSE OF THIS.
