I still think it is ZERO
A bearing of zero degrees is directly North, and you can't get much steeper than perpendicular!

I think you are probably right, jj109 although I don't think it's a great clue if that is the answer - bearing would have been better than angle since angles need a unit (degrees)

the zoom suggestion may relate to zoom climbs for aircraft
