Narrative:

Flight departed mdt at XX00 local time to ilg airport. While at 5000 ft in cruise confign and approximately 15 mi northwest of ilg on an airway a near miss with a glider almost occurred. There was a broken layer approximately 500 ft above our aircraft and the glider was evidently using thermals created under the clouds. We spotted the glider when he was approximately 1/4 to 1/2 mi away, fortunately both planes reacted using the right of way rules and each plane turned right. Had the pilot of our aircraft not reacted like he did it would have been very close. We reported the near miss to phl approach but they can not see gliders on their radar, so there wasn't much they could do. The only suggestion I have is more awareness be presented to gliderports about their operations. Especially gliderports that are located in close proximity to high density airports.

Original NASA ASRS Text

Title: FLC OF AN LTT TOOK EVASIVE ACTION TURN TO AVOID FURTHER CONFLICT WITH A GLIDER.

Narrative: FLT DEPARTED MDT AT XX00 LCL TIME TO ILG ARPT. WHILE AT 5000 FT IN CRUISE CONFIGN AND APPROX 15 MI NW OF ILG ON AN AIRWAY A NEAR MISS WITH A GLIDER ALMOST OCCURRED. THERE WAS A BROKEN LAYER APPROX 500 FT ABOVE OUR ACFT AND THE GLIDER WAS EVIDENTLY USING THERMALS CREATED UNDER THE CLOUDS. WE SPOTTED THE GLIDER WHEN HE WAS APPROX 1/4 TO 1/2 MI AWAY, FORTUNATELY BOTH PLANES REACTED USING THE RIGHT OF WAY RULES AND EACH PLANE TURNED R. HAD THE PLT OF OUR ACFT NOT REACTED LIKE HE DID IT WOULD HAVE BEEN VERY CLOSE. WE RPTED THE NEAR MISS TO PHL APCH BUT THEY CAN NOT SEE GLIDERS ON THEIR RADAR, SO THERE WASN'T MUCH THEY COULD DO. THE ONLY SUGGESTION I HAVE IS MORE AWARENESS BE PRESENTED TO GLIDERPORTS ABOUT THEIR OPS. ESPECIALLY GLIDERPORTS THAT ARE LOCATED IN CLOSE PROX TO HIGH DENSITY ARPTS.
