Aircraft; Human Factors; Weather
After deice procedure (Type 1 and 4) we had a long taxi; performing a crossbleed start on the taxiway. After a normal power up and acceleration to V1/Vr; First Officer (flying pilot); reported that the aircraft would not rotate and he was aborting the takeoff. A quick visual check by me showed that he had the yoke pulled way back and was just getting the nose wheel off the ground. We aborted the run and returned to gate for maintenance inspection. Prior to taxi [Load Planning] had us move 3 passengers aft; filling the last seats. Failure to achieve normal rotation. I feel that procedures were followed; and a safe outcome resulted.
The Captain states that he had to rely on the First Officer's judgment in this situation and reject the takeoff; as there appeared there was sufficient runway remaining to stop. The aircraft was easily stopped and taxied back to the gate. Maintenance; unfortunately could find no discrepancies and the aircraft flew later that day. He also reported that a substantial amount of type IV fluid was noted to be coating the bottom of the horizontal stabilized upon returning to the gate; which may have affected the way the elevator 'felt' to the First Officer.
Normal Operations on a snow weather day. De-iced with Type 1 and anti-iced with Type 4. [We] utilized Company De-icing/Anti-icing Checklist prior to and following procedures. No APU onboard aircraft and with long lines for runway taxied out on Engine Number 2. Completed crossbleed start prior to end of taxi for times and temperatures. [We] ran checklists accordingly. [We] were cleared into position and cleared for takeoff. Following all callouts to rotation speed by Captain; non-flying pilot engines and instruments were crosschecked and shown to be normal. At rotation call out I attempted rotation finding the yolk heavy and utilizing almost full back deflection to create rotation; rotation was slow and not normal; extreme backpressure and no sign of full rotation. At this time I called no ability to fully rotate and a call for aborted takeoff. At which time the Captain executed the aborted takeoff procedure accordingly. I contacted ATC; as well as spoke to the passengers. I was then instructed to contact Operations; as well as Maintenance while the Captain contacted Ground for taxi instructions. The aircraft was taxied back without incident to gate for maintenance inspection. High speed abort at rotation speed. Excessive speed with a lot of runway behind us.
EMB145 flight crew reports rejecting a takeoff after Vr due to failure to rotate. The aircraft is successfully stopped on the runway and taxied back to the gate.
