1. Tires Table 12.1 Principal Chassis Tuning Items a. Different designs, sizes and front/rear combinations b. Tire pressures/tire temperatures c. Stagger (different tire circumference) frequently used across an axle d. Rim widths and offsets (possible track change) e. Static alignment (toe, camber, caster) 2. Static Wheel Loads a. Longitudinal CG location (shifting ballast) b. Lateral CG location (shifting ballast) c. Wedge, diagonal weight jacking, or warp (changes in spring preload) 3. Lateral Load Transfer Distribution (LLTD) a. Roll couple distribution front to rear b. Roll center heights (front and/or rear) c. Ride spring rates d. Anti-roll bars or Z-bars e. Progressive rate springs, linkages and bump stops (Notes: Coupling occurs with ride height changes when progressive rate linkages are used. Cockpit adjustment of LLTD may be provided.) 4. Ride Height and Body Attitude (Roll and Pitch) a. Wheel orientation changes via suspension geometry • Camber curves • Ride (bump)/roll steer • Anti-dive/squat • Steering geometry • Wheel travel b. Aerodynamics (function of ride height and body attitude) Table 12.2 Additional Principal Chassis Tuning Items 1. Aerodynamic Forces and Moments a. Lift/downforce b. Drag c. Pitching and yawing moments (Note: As affected by size, shape, angle of wings, car shape/underbody, internal air flow, etc.) 2. Brakes a. Distribution, front to rear b. Cooling 3. Driveline a. Gearing b. Differential(s), type and functional behavior c. Spool d. Engine performance characteristics 4. Dampers 5. Driver/Vehicle Interface a. Steering ratio b. Pedal forces and movements c. Force feedbacks (kickback, oscillations) 6. Compliances a. Chassis and suspension stiffness maximized by design b. Suspension compliances are not adjustable for tuning (as in road cars)

Four months into a six month deployment, you are a solo pilot returning to home base after an uneventful overwatch mission to a non-disclosed desert location. Your mission was extended 90 minutes requiring at least one additional aerial refuel. The moon has now set. A shift in prevailing winds causes an infrequently used runway to be active. You are less familiar with the approach to this runway and have only used it during VFR conditions. The instrument approach plate reveals you will fly a prolonged DME arc taking you out over the unlit desert away from the dimly lit base. While flying the above instrument approach, you take another look at the approach plate. When you look up again the airfield lights are visible through the upper portion of your canopy. You did not sense any change in your aircraft attitude. Which of the following best describes what happened while you looked at the approach plate? OA. The black hole effect has amplified the normal reflection of the airfield lights…
