What are the points of contact that an aerial has?

• A. Flat ground clearance, angle of approach, wheel base, ramp breakover angle, and angle of departure
• B. Wheel base, ground clearance, angle of departure
• C. Angle of approach, wheel base, engine torque, and suspension travel
• D. Ground clearance, wing span, tail height, rotor speed

Answer: (A)

Understanding how an aerial interacts with the ground hinges on its contact points—the parts of the vehicle’s geometry that determine how it sits, moves, and clears obstacles. Flat ground clearance tells you how high the chassis sits above the ground and whether you’ll clear bumps or curbs. The angle of approach shows how steep an obstacle the front end can meet without the bumper or structure hitting first. The wheel base—the distance between the front and rear axles—affects stability and weight distribution during turns and when the aerial is extended. The ramp breakover angle (breakover angle) indicates the maximum slope the vehicle can traverse or crest without the undercarriage scraping. The angle of departure describes how steep an obstacle at the rear can be cleared as you move away. Together, these factors describe how safely the aerial can contact and interact with ground and obstacles during setup, positioning, and operation. Other listed features, like engine torque or unrelated vehicle dimensions, aren’t about how the aerial contacts the ground.
