Amendment 42 applies to FAR25-107(1978)which applies to all Types..Thats why the VEF definition appeared in the AFM's,or should be..
cheers
True, not all types took into account the, Amendment 42,two seconds more of runway distance required for the accelerate stop distance..And to date only the B777 has complied to all the nes rules(Boeing give the non FAR carriers the JAA data in their AFMs-performance B)...Never the less ,should one have occasion to refer to the REGS,the current references only reflect post amendment 42..
Cheers
