And windshear recovery mode will be shown with FD on/armed regardless of VNAV armed before take off.
Wasn't there a notice to users or some such that there's a bug with VNAV regarding windshear? I think the jet would exit TO/GA and you'd have to hit it again while in the recovery.
NADP-1 is easier to accomplish in VNAV than is NADP-2 (at least with my then airline's profile).
