Pop-Up attack

A question I have is the use of pop-up attacks when within  LOS and
36" of ADS. Does the the VTOL come under attack from ADS? How I solve
the problem is make the VTOLs in question make a reaction test at +2
to preform a pop-up attack in this position, If a 1 is rolled, the one
of VTOL comes under ADS before forced down. I am open to any other
answer to problem.

Thank you,
Rick N.
