Narrative:

I flew through R-3401 because I believed the area to be cold. Being unfamiliar with the general area I interpreted tue-sat to be tue and sat rather than tue through sat. To avoid this happening in the future I would suggest that the hyphen be eliminated and the word through used instead. Callback conversation with reporter revealed following information. Reporter states he found out about the airspace penetration upon landing when told to call FAA. Feels pretty foolish to have misinterpreted days of operation. Use of hyphen one place and 'thru' in another does cause confusion.

Original NASA ASRS Text

Title: PENETRATION OF RESTRICTED AIRSPACE.

Narrative: I FLEW THROUGH R-3401 BECAUSE I BELIEVED THE AREA TO BE COLD. BEING UNFAMILIAR WITH THE GENERAL AREA I INTERPRETED TUE-SAT TO BE TUE AND SAT RATHER THAN TUE THROUGH SAT. TO AVOID THIS HAPPENING IN THE FUTURE I WOULD SUGGEST THAT THE HYPHEN BE ELIMINATED AND THE WORD THROUGH USED INSTEAD. CALLBACK CONVERSATION WITH RPTR REVEALED FOLLOWING INFO. RPTR STATES HE FOUND OUT ABOUT THE AIRSPACE PENETRATION UPON LNDG WHEN TOLD TO CALL FAA. FEELS PRETTY FOOLISH TO HAVE MISINTERPRETED DAYS OF OPERATION. USE OF HYPHEN ONE PLACE AND 'THRU' IN ANOTHER DOES CAUSE CONFUSION.
