Thanks Tango.
I knew about setting 40% initially to allow the engines to stabilise (and "equalise") but I wasn't sure whether the TOGA buttons (on Boeings) commanded the pre-arranged derated thrust or were there for "Yikes! We suddenly need everything we've got!" and you've answered that, Thanks.
Is there any such thing as a pre-arranged derated go-around thrust or is that always full power (if doing it via the TOGA buttons rather than maually advancing the TL's). Seem to remember a thread on here suggesting full power at GA was not always appropriate.
