  "description": "Normal procedure checklist for the Piper PA-28-161 Warrior II, a low-wing fixed-gear trainer with a Lycoming O-320 engine, fixed-pitch propeller, and manual flap lever. Fuel selector (LEFT / RIGHT / BOTH) is a key operational difference from high-wing trainers — confirm the detent is engaged at each selection. Wing fuel levels can be checked visually through small windows in the leading edge. No airspeeds, power settings, fuel quantities, or other numerical limits are stated — those must come from the specific aircraft's POH. Verify every item against the actual aircraft before flight.",
