Lyman - I don't think so.
The airplane’s pitch attitude increased progressively beyond 10 degrees and the plane started to climb.
The important word there is
and. If the climb did not begin until 10 degrees nose-up had been reached, the correct word would be
"then". "And" simply states that two things happened, whereas "then" would imply one thing happened after the other.
"As the Pitch increased beyond ten degrees NOSE UP, the a/c continued its climb?"
All this means is that nothing has changed in terms of general aircraft response. The pitch angle increases beyond +10deg, and the aircraft continues the climb it began as soon as the aircraft began to pitch up past the cruise trim pitch.
