Summary	0000192: Hornet: pitch-trim target AOA is established when setting flaps to 'half' or 'full', not gear-down
Description	NOTE: I do not know if this is a doc-bug or a RL discrepancy. But the FLCS pitch-trimming-to-control-AOA mode appears to be activated by flaps, not deploying gear.
Steps To Reproduce	Repro steps (1 of 3): - Stock BMS 4.35.2, KTO .. fly the Hornet in TR#24 - at 250 kts, about 6° AOA, with flaps=Auto, lower gear - vary throttle from 20% to 80% mil and back - Observe: nose stays mostly steady; doesn't pitch up or down to track to 6° above FPM - Expect: (per Naval Ops doc) jet enters pitch-trim mode, with target AOA set at moment of gear-deployment time Repro steps (2 of 3): - with flaps still in Auto, raise the gear - cut throttle to idle .. at approx 5° AOA set flaps=Half - vary throttle from 20% to 80% mil and back, slowly - Observe: nose tracks up and down with AOA, staying 0000002:0000005° above FPM - Expect: nose does not track 5° AOA with gear up Repro steps (3 of 3): - gently pull back on stick to achieve 8° AOA (circle on indexer) - extend flaps further (set flaps=Full) - vary throttle from 20% to 80% mil and back - Observe: nose tracks up and down with AOA, staying 0000006:0000008° above FPM - Expect: nose does not track 8° AOA with gear up
