📘14 CFR §91.129 – Operations in Class D Airspace
🚩 Overview
Pilots operating in Class D airspace must maintain clear communication with Air Traffic Control (ATC), follow specific operational procedures, and adhere to mandatory instructions from the control tower.
✅ Key Operational Requirements
🛫 1. Communications
Establish two-way radio communication with ATC before entering Class D airspace.
Maintain communication while operating within Class D airspace.
🛩 2. Operating Procedures
Comply with ATC instructions, clearances, and traffic pattern directions provided by the control tower.
If ATC assigns a runway, pilots must use that assigned runway unless given permission otherwise.
Taxi, takeoff, and landing clearances must be obtained from ATC.
🛬 3. Equipment Requirements
Aircraft must have an operational two-way radio for communication with ATC.
🌙 4. Departures from Satellite Airports (No Control Tower)
When departing from a non-towered airport within Class D airspace, establish communication with the primary control tower as soon as practical after departure.
🛩️ Example Scenario
You're flying toward a Class D airport. You must call the control tower on the published frequency before entering their airspace. Once you establish two-way radio contact (ATC acknowledges your callsign), you may enter the airspace. Always comply promptly with any ATC instructions provided.
📌 CFI Pro Tips
