Yeah, there has been confusion about this for a long time.
A chap who went on to become one of Okie's C/P's and I had an uhmmm, ... strong debate about it.
He insisted we could use 721 and 102.3 for T/O with both engines operating. My take from the GE manual was 696 and 100.
Where -2 really helped us was if we lost a donk.
And loggers? Well, they are .... loggers - after all
