A taxi clearance to an assigned takeoff runway authorizes the aircraft to cross all taxiways ___.

• A. and active runways
• B. and non active runways
• C. and runways along the route
• D. the taxi route intersects

Answer: (D)

The key idea is that a taxi clearance to an assigned takeoff runway only covers crossings on the aircraft’s actual route to that runway. You are authorized to cross only those taxiways that intersect that taxi route. If a taxiway does not cross (intersect) the planned path, you’re not cleared to cross it under this clearance.

So, you’d cross every taxiway where your route intersects, and you would not cross taxiways that run beside or parallel to the route or that don’t intersect it. Also, it’s important to note that crossing an active or non-active runway isn’t granted by this taxi clearance; runway crossings require separate explicit clearance.
