Airport; Human Factors
While conducting a routine passenger flight under Part 91 in a Dassault Falcon 10; a problem arose on descent when it was discovered that our airport of intended landing was closed due to thick ice on the runway. The flightand departed at approximately XA57 local time. Due to the early showtime; I had downloaded our flight plan; weather; and NOTAMs the night before and reviewed them before going to bed. During the descent to the airport; I recalled that there had been freezing rain the night before; and called UNICOM to ask about the condition of the runways. UNICOM informed me that all runways were closed; and I in turn advised ATC. ATC then called the airport to double check; during which time I pulled out the notams to review. Sure enough there had been a NOTAM filed after our departure that both runways were closed. We advised ATC we would like to divert to Jamestown New York; JHW; and the flight diverted and landed there safely with no other issues.I believe this issue arose due to several contributing factors. First and foremost; the early show time was a primary reason I did most of my preflight planning and reviewing the night before; and thus neglected to review any updated NOTAMs the morning of departure.Secondly; our flight department normally operates in warmer climates. Despite being aware of freezing rain the night before; this could be a reason why I did not think to double check for runway NOTAM's again the following morning. Winter runway contamination has rarely been a factor at our normal warmer destinations. This could have caused a bit of complacency when it comes to winter operationsSecondly; our flight department normally operates in warmer climates.
