Narrative:
I (aircraft X) was flying east, aircraft Y (piston twin) was flying nwbound. It appeared from directly in front of the sun and appeared on a collision course, at close range. Turning to my left would have put me in front of a faster aircraft. Turning right would have increased collision risk. I elected to climb, but did not have adequate speed, lost sight of second plane and stalled, nearly inverted. I then pulled and completed a loop, which gave adequate altitude and delay to miss the plane. Entry speed would have permitted a climbing turn had I not pulled so hard. A more gentle pull after the stall would have allowed a course reversal away from the second plane. The primary problem was that it was directly in front in the sun. This is clearly an omen at decreased visibility which must be watched. It is still not clear to me how close we came, since I did not get a good look until later.
Original NASA ASRS Text
Title: CH10 PLT INITIATES AGGRESSIVE EVASIVE MANEUVER WHEN OBSERVING ANOTHER ACFT ON APPARENT COLLIDING COURSE.
Narrative: I (ACFT X) WAS FLYING E, ACFT Y (PISTON TWIN) WAS FLYING NWBOUND. IT APPEARED FROM DIRECTLY IN FRONT OF THE SUN AND APPEARED ON A COLLISION COURSE, AT CLOSE RANGE. TURNING TO MY L WOULD HAVE PUT ME IN FRONT OF A FASTER ACFT. TURNING R WOULD HAVE INCREASED COLLISION RISK. I ELECTED TO CLB, BUT DID NOT HAVE ADEQUATE SPD, LOST SIGHT OF SECOND PLANE AND STALLED, NEARLY INVERTED. I THEN PULLED AND COMPLETED A LOOP, WHICH GAVE ADEQUATE ALT AND DELAY TO MISS THE PLANE. ENTRY SPD WOULD HAVE PERMITTED A CLBING TURN HAD I NOT PULLED SO HARD. A MORE GENTLE PULL AFTER THE STALL WOULD HAVE ALLOWED A COURSE REVERSAL AWAY FROM THE SECOND PLANE. THE PRIMARY PROB WAS THAT IT WAS DIRECTLY IN FRONT IN THE SUN. THIS IS CLRLY AN OMEN AT DECREASED VISIBILITY WHICH MUST BE WATCHED. IT IS STILL NOT CLR TO ME HOW CLOSE WE CAME, SINCE I DID NOT GET A GOOD LOOK UNTIL LATER.
