Narrative:

I was flying from ZZZ1 to ZZZ2. The flight inadvertently encroached into a tfr area near the city. Mr X was using a VOR radial and distance to identify the tfr area. Apparently that does not provide sufficient resolution for accurate identification, even though it was included in the NOTAM. We were not aware of the problem until we landed at ZZZ2 and were asked to contact the tower. No flight safety issues were involved. Since pilot mr X was responsible for all navigation I could not have been aware of our position. Tfr areas should be identified more accurately in NOTAMS.

Title: PLT ENTERED A TFR EVEN THOUGHT HE WAS USING THE GIVEN NOTAM INFO TO REMAIN CLR OF THE AREA.

Narrative: I WAS FLYING FROM ZZZ1 TO ZZZ2. THE FLT INADVERTENTLY ENCROACHED INTO A TFR AREA NEAR THE CITY. MR X WAS USING A VOR RADIAL AND DISTANCE TO IDENTIFY THE TFR AREA. APPARENTLY THAT DOES NOT PROVIDE SUFFICIENT RESOLUTION FOR ACCURATE IDENTIFICATION, EVEN THOUGH IT WAS INCLUDED IN THE NOTAM. WE WERE NOT AWARE OF THE PROBLEM UNTIL WE LANDED AT ZZZ2 AND WERE ASKED TO CONTACT THE TWR. NO FLT SAFETY ISSUES WERE INVOLVED. SINCE PLT MR X WAS RESPONSIBLE FOR ALL NAVIGATION I COULD NOT HAVE BEEN AWARE OF OUR POSITION. TFR AREAS SHOULD BE IDENTIFIED MORE ACCURATELY IN NOTAMS.
