MENU (bezel hard key) now opens a G1000-style PAGE MENU (Invert / Store / Delete flight plan) instead of only mirroring the sim command. HRZN HDG draws heading reference marks (N/E/S/W + ticks) along the attitude horizon, toggled from the PFD submenu. With TRAFFIC/NEXRAD/PROFILE/PATHWAY/APTSIGNS already wired, every softkey now does something; only ENT remains a pure sim-command mirror. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
