TKOF ABORTED. TKOF DELAYED.

Narrative

ON DEP WITH A V1 117 VR 117 V2 127; THE CAPT ABORTED PAST V1; IN FACT SPD AT ABORT WAS JUST BELOW V2 AS I HAD NOT YET MADE THAT CALLOUT. THE RTO FEATURE WAS IN USE AND MAX REVERSE THRUST WAS APPLIED; THE ACFT STOPPED WITH 1000 FT OF RWY REMAINING. BACKGND: WX WAS HIGH OVCST WITH LIGHT SNOW FALLING. OAT 21 DEGS F (APPROX) A STRONG XWIND WAS BLOWING OUT OF THE W (AS I REMEMBER IT WAS ABOUT 340 DEGS AT 21 G 25). DURING PREFLT I NOTICED ICE HAD FORMED ON THE FUSELAGE BUT IT WAS CLR THAT THE WINGS HAD BEEN DE- ICED. I LATER MENTIONED THIS TO THE CAPT BUT HE STATED THAT THEY HAD JUST FINISHED DE-ICING AND ALL WAS CLR (HE HAD OBSERVED THE FINAL DE-ICE). WE PUSHED BACK; STARTED ENGS; RAN CHKLISTS (ENG ANTI-ICE ON). WE WERE CLRED FOR TKOF AND PROCEEDED TO GO. STAND UP WAS NORMAL; AUTO THROTTLES ADVANCED THE PWR TO TKOF AND ALL ENG INDICATIONS WERE NORMAL. AS AIRSPD APCHED 80 KTS; THE EFFECTS OF THE XWIND WERE NOTICEABLE. HOWEVER; THE CAPT DID NOT APPLY AILERON INTO THE WIND (NOT THAT BIG A DEAL). AT 117 KTS HE ROTATED THE ACFT (2-3 DEGS PER SECOND) AND I FELT AND SAW THE L WING RISE A LITTLE. AT THIS POINT HE ADDED 10 DEGS OF CTL WHEEL DEFLECTION WHICH WAS INSUFFICIENT TO COUNTERACT THE XWIND. JUST AS I WAS GOING TO ADD SOME CTL INPUT FOR HIM; HE ELECTED TO ABORT; CLOSED THE THROTTLES (HE NEVER DID ANNOUNCE THE ABORT); PUT THE ENGS INTO REVERSE. I CALLED THE TWR AND MADE A PA AS WE CLRED THE RWY. DURING THIS TIME; HE TOLD ATC THAT WE ABORTED FOR A TKOF WARNING HORN (WE HAD NO MALFUNCTION OF THAT SYS); AND WE RETURNED TO THE RAMP WHERE HE WROTE IT UP AS A TKOF WARNING AT 125 KTS. HE THEN STATED THAT HE FELT THERE WAS ICE ON THE R WING AND SO WHEN HE FELT IT ROLL R HE ELECTED TO ABORT. THERE WAS NO ICE; THE WINGS WERE CLR AND FREE. HE SIMPLY DID NOT USE ENOUGH AILERON CTL INTO THE WIND. AFTER 64 MINS FOR BRAKE COOLING; WE CONTINUED WITHOUT INCIDENT.
