Narrative:

I failed to set the flaps to 5 degrees before the 'before taxi checklist.' the captain and I did not notice during the checklist that the flaps were at 2 degrees not 5 degrees. After he set the power and called set takeoff thrust; I verified it set. Captain then noticed flaps were at 2 degrees not 5 degrees. He then asked me to set them to 5 degrees. I responded and we continued without incident. We were light weight on a long; dry runway so I felt that what he did was safer and more comfortable to the passenger than rejecting. Better verification during the checklist! In the lighting conditions at the time; at a glance; the flaps looked to be in the proper position.

Narrative: I FAILED TO SET THE FLAPS TO 5 DEGS BEFORE THE 'BEFORE TAXI CHKLIST.' THE CAPT AND I DID NOT NOTICE DURING THE CHKLIST THAT THE FLAPS WERE AT 2 DEGS NOT 5 DEGS. AFTER HE SET THE PWR AND CALLED SET TKOF THRUST; I VERIFIED IT SET. CAPT THEN NOTICED FLAPS WERE AT 2 DEGS NOT 5 DEGS. HE THEN ASKED ME TO SET THEM TO 5 DEGS. I RESPONDED AND WE CONTINUED WITHOUT INCIDENT. WE WERE LIGHT WT ON A LONG; DRY RWY SO I FELT THAT WHAT HE DID WAS SAFER AND MORE COMFORTABLE TO THE PAX THAN REJECTING. BETTER VERIFICATION DURING THE CHKLIST! IN THE LIGHTING CONDITIONS AT THE TIME; AT A GLANCE; THE FLAPS LOOKED TO BE IN THE PROPER POS.
