Narrative:

I mistakenly used flaps 1 chart to compute V speeds for a flaps 5 takeoff. Fortunately we were light and loaded (approximately 90000 pounds). Captain did not catch the error since light weight flaps 1 speeds were approximately what we would expect for flaps 5 speeds. To correct, recommend V speeds chart placarded in all air carrier X airlines airplanes.

Title: INCORRECT FLAP SET 'V' SPDS SELECTED BY FO BEFORE TKOF. CITES LACK OF PLACARD IN ACFT PREVENTED PIC FROM CATCHING ERROR.

Narrative: I MISTAKENLY USED FLAPS 1 CHART TO COMPUTE V SPDS FOR A FLAPS 5 TKOF. FORTUNATELY WE WERE LIGHT AND LOADED (APPROX 90000 POUNDS). CAPT DID NOT CATCH THE ERROR SINCE LIGHT WT FLAPS 1 SPDS WERE APPROX WHAT WE WOULD EXPECT FOR FLAPS 5 SPDS. TO CORRECT, RECOMMEND V SPDS CHART PLACARDED IN ALL ACR X AIRLINES AIRPLANES.
