2nd Segment climb gradient.
JAR/FAR 25.121 states (with One Engine Inop)
.......but without ground effect, the steady gradient
of climb may not be less than 2·4% for two-engined...
My question, what does "steady mean"?
Since, as airplane climbs performance decreases, does it mean the minimum acceptable gradient when minimum acceleration altitude (not less than 400 feet and can be increased by operators for their performance calculation) is reached or the minimum instantaneous value at the beginning of second segment (35 feet)?
Thanks
