When an airplane is operating under visual meteorological conditions, the captain holds the responsibility of avoiding collisions with other aircraft. Nevertheless, due to the confined space on and around the airfield, providing traffic information becomes imperative to assist the captain in collision avoidance. As an air traffic and controller knows this thing:

Crucial Airfield Information

• Any construction work along or near the runway in use.
• Rough areas of the maneuvering zone, whether marked or not.
• Presence of maintenance apparatus or workmen on or near areas utilized by aircraft.
• Runway or taxiway conditions indicate slipperiness.
• Malfunction or irregular operation of any part of the airfield lighting system.
• Any other relevant information.
• Timely provision of essential aerodrome condition details to all concerned aircraft for their proper utilization. While standard regulations do not inhibit controllers from exercising initiative during unusual situations, permanent deviations from these standards are only admissible if officially published as local air traffic control orders. Controllers must ensure that any local procedures do not compromise the safety or efficiency of visiting aircraft movements.

Control of Taxiing Aircraft

Special attention must be given to prevent accidents resulting from careless aircraft taxiing or reckless driving of ground vehicles. Aerodrome commanders are tasked with implementing measures to prevent such accidents, tailored to the specific circumstances and potential risks. Responsibilities include:

• Marking runway and taxi tracks following AIP guidelines.

Air traffic and controller in the Maneuvering Area

Movement of individuals or vehicles within the maneuvering area that may interfere with airfield traffic is prohibited unless authorized by the aerodrome control tower. Individuals, including vehicle drivers, must halt and await clearance from the control tower before crossing any runway or taxiway.

Control of Departing Aircraft (Visual Flight Rules)

Takeoff clearance for an aircraft is contingent upon the preceding aircraft crossing the end of the runway in use or all preceding landing aircraft clearing the runway. Additionally, clearance from approach control is required before takeoff, with the approach control office promptly transmitting the clearance to the control tower. The pilot in command receives necessary information before takeoff, including wind conditions, runway in use, altimeter settings, and air traffic control clearance.

Control of Arriving Aircraft (Visual Flight Rules)

Landing aircraft must not cross the aerodrome boundary in its final approach until the preceding departing aircraft is airborne or all preceding landing aircraft have cleared the runway in use. Exceptions include aircraft in formation, operating in different areas, or landing on airfields equipped for simultaneous landings or takeoffs.

Control of Arriving Aircraft (Instrument Flight Rules)

Successive aircraft operating in instrument meteorological conditions are only authorized to commence final descent for landing once the preceding aircraft has reported visibility to the aerodrome control tower, ensuring a safe landing is feasible.

Control of Departing Aircraft (Instrument Flight Rules)

Departing aircraft may take off in any direction if the arriving aircraft is conducting a complete instrument approach. If the arriving aircraft is making a straight-in approach, departing aircraft must adhere to specific directional requirements.

Suspension of Visual Flight Rules Operations

The airfield control tower may suspend visual flight rules operations in the interest of safety, implementing procedures to hold departures and recall local flights operating under visual flight rules. The approach control office and flight information center are notified accordingly.

Asymmetric Landings/Overshoot Procedures

Rules governing aircraft landing with asymmetric power or overshooting are outlined. Air traffic and controller clearance is mandatory before executing such maneuvers, and exercises are subject to weather and airfield limitations to ensure safety.
