Which of the following is NOT part of the clearance items spoken by a controller?

Answer: A — Departure speed

The clearance items given by air traffic controllers typically include the route of flight, the squawk code, and the initial altitude. These elements are vital for ensuring that pilots are informed about their intended path and operational requirements once they enter controlled airspace. Departure speed, however, is generally not specified as a part of the initial clearance given to pilots. Instead, air traffic controllers may provide speed instructions during the flight or subsequent clearances, based on traffic conditions and safety considerations. The initial clearance primarily focuses on establishing the route, transponder settings, and initial altitude to ensure a safe departure and integration into the air traffic system.
