Narrative:

2 aircraft ready for departure with similar call signs. Air carrier X was VFR with an arsa heading of 030 degree, and air carrier Y was IFR on a sunol 2 departure. I departed air carrier X then, looking at the wrong flight progress strip, and departed air carrier Y on a 340 heading and altitude restriction of 1500' or below, VFR, which the pilot accepted without question. When air carrier Y was about 3 mi from the airport, I realized my error and contacted approach control and advised him of the occurrence, and handed off air carrier Y to his control.

Original NASA ASRS Text

Title: DUE TO MISREADING OF FLT PROGRESS STRIP, AN IFR ACR WAS RELEASED USING VFR SEPARATION STANDARDS.

Narrative: 2 ACFT READY FOR DEP WITH SIMILAR CALL SIGNS. ACR X WAS VFR WITH AN ARSA HDG OF 030 DEG, AND ACR Y WAS IFR ON A SUNOL 2 DEP. I DEPARTED ACR X THEN, LOOKING AT THE WRONG FLT PROGRESS STRIP, AND DEPARTED ACR Y ON A 340 HDG AND ALT RESTRICTION OF 1500' OR BELOW, VFR, WHICH THE PLT ACCEPTED WITHOUT QUESTION. WHEN ACR Y WAS ABOUT 3 MI FROM THE ARPT, I REALIZED MY ERROR AND CONTACTED APCH CTL AND ADVISED HIM OF THE OCCURRENCE, AND HANDED OFF ACR Y TO HIS CONTROL.
