Which of the following items is typically included in a pre-trip AVOP vehicle inspection?

• A. Tires/tread
• B. Horn color
• C. Passengers' seating preference
• D. Alarm system color

Answer: (A)

A pre-trip AVOP vehicle inspection focuses on safety-critical components that affect the vehicle’s ability to operate safely around aircraft and personnel. Tires and tread are a core part of this because the condition of the tires directly influences grip, braking, and stability. You check tread depth to ensure there’s enough rubber for traction, inspect for cuts, bulges, embedded objects, and uneven wear, and verify proper inflation according to the manufacturer’s specification. Poor tire condition or underinflation can lead to blowouts or poor handling on ramp surfaces, creating serious safety risks. That’s why tires/tread are routinely included in the pre-trip check.

The other options are not part of the standard safety inspection: horn color, passengers’ seating preference, and alarm system color are cosmetic or comfort aspects and do not affect the vehicle’s safe operation during a pre-trip inspection.
