There's a difference between minimum V2 (V2min) - and actual V2 being used for climbout:
From JAR 25, Section 1:
[(b) V2MIN, in terms of calibrated airspeed,
may not be less than –
(1) 1·13 VSR for –
(i) Two-engined and threeengined
turbo-propeller powered
aeroplanes; and
(ii) Turbojet powered aeroplanes
without provisions for obtaining a
significant reduction in the one-engine inoperative
power-on stall speed;]
[(2) 1·08 VSR for –
(i) Turbo-propeller powered
aeroplanes with more than three engines;
and
(ii) Turbojet powered aeroplanes
with provisions for obtaining a significant
reduction in the one-engine-inoperative
power-on stall speed: and
(3) 1·10 times VMC established under
JAR 25.149.]
(c) V2, in terms of calibrated airspeed, must
be selected by the applicant to provide at least the
gradient of climb required by JAR 25.121(b) but
may not be less than –
[(1) V2MIN;
(2) VR plus the speed increment
attained (in accordance with JAR 25.111(c)(2))
before reaching a height of 35 ft above the
take-off surface; and
(3) A speed that provides the
manoeuvring capability specified in JAR
15.143(g).]
