A First Officer allowed the aircraft to slow during takeoff in foul weather because he was unfamiliar with the new flat panel PFD so the Captain nudged the yoke forward to aid airspeed recovery.
Departed on Flat-Panel Display aircraft. Due to rain showers and wind gusts in the vicinity; we elected to perform a max power takeoff. Aircraft weight was approximately 200;000 LBS. First Officer was pilot flying and has not often seen or operated a Flat-Panel aircraft on the line. Due to lighter aircraft weight; wind gusts and pitch fluctuations of the command V-bar and a higher initial pitch up with max power; airspeed began to bleed back toward V2. As pilot not flying; I reminded First Officer of pitch attitude and nudged the yoke forward to assist recovery of airspeed. Flaps remained at takeoff setting until airspeed recovered. Continued climb out and clean-up on schedule as airspeed increased. I believe that First Officer's lack of regular and recent experience with the flat-panel display allowed for pitch and airspeed transgressions out of the normal takeoff range. Also; I could have provided more timely pitch and airspeed feedback to pilot flying to help avoid this situation. Continued and discussed what could have prevented a re-occurrence of this situation.
Thunderstorms; precipitation and not very familiar with flat panel equipment were factors. On climb out; pilot flying pitched up toward command bars as autothrottles pulled throttles back. Pilot flying slow to recognize airspeed getting slow for present configuration. Pilot not flying pushed yoke forward and slowed climb rate down to allow aircraft to accelerate. Pilot flying also pushed throttles up to increase airspeed.
