Back in the dark ages when the JAA were collecting question data bases from schools to write the first JAA QB the UK CAA offered to re-write the weirdest translations into clear English. The Europeans rejected this offer on the grounds that we spoke English, and that what they wanted was a sort of pigeon "Europinglish" that they could understand.

 

We still try and weed out the worst questions by referring them to the CAA

 

This one is rather strange, as it is self answering. If "tuck under" means a nose down trim change, then what gives you this? CP forward or back?  More or less downwash on the tail?

 

"Tuck under" is a loose throwback to the early days of high speed flight, when (personal experience) a Vampire 5 would violently tuck under, inducing some negative g - at about M0.78.

 

The question is badly worded, and of no value.
