Which statement best differentiates Runway Incursion from CMAV?

• A. Runway Incursion is on the runway; CMAV can involve taxiways as well
• B. CMAV is only on taxiways
• C. Runway Incursion involves weather
• D. CMAV involves signage only

Answer: (A)

The key idea is understanding what each term covers in the airfield movement area. A Runway Incursion happens when an unauthorized aircraft, vehicle, or person enters the runway surface and could interfere with an aircraft using that runway. CMAV, or Cleared Movement Area Violation, describes operating in the movement area without proper clearance, and that movement area includes both runways and taxiways. So, Runway Incursion is specifically about the runway surface, while CMAV can occur anywhere in the movement area, including taxiways. The other statements don’t fit because CMAV is not limited to taxiways only, Runway Incursion is not defined by weather, and CMAV is not about signage only.
