for an aircraft on the ground: Taxi clear of landing area or runway in use
for aircraft in the air: Airport unsafe- Do not land
for vehicles on the ground: Clear the taxiway/runway
A flashing white control tower light signal indicates that the aircraft should return to the starting point or the ramp. This signal is typically used when there is a need for the aircraft to taxi back to its original position, often due to a request from air traffic control or a safety concern. Pilots should always follow specific instructions from air traffic control when interpreting light signals.
A flashing red light from a control tower typically signifies that an aircraft must not take off or land. This warning indicates a potential hazard, such as poor visibility or an obstruction on the runway. Pilots are required to maintain their position and await further instructions from air traffic control. Compliance with these signals is crucial for ensuring safety in aviation operations.
Exercise extreme caution.
It means get off the runway now, or, if flying, do not land here.
A flashing red traffic light is used the same way as a stop sign. You treat a flashing red traffic light the same way you do as a stop sign. If the traffic light is "blacked-out", it's to be treated as an all-way stop. What I do when I come up to a flashing red traffic light, I look at the cross-traffic signals to see if they're also flashing red, or if they're flashing yellow to see if they stop or if they don't stop.
A flashing red traffic light is treated the same as a regular red traffic light because it indicates that drivers must come to a complete stop before proceeding.
The red flashing traffic light means that you are to come to a stop, yield to other traffic and then you can procede when the way is clear.
It's fancy wording for one of two things. (1) You ran a stop sign. (2) You ran a red light. Either one is a traffic violation, and gets you a ticket. Any device that can legally be used to control traffic such as a sign or a flashing light is also a traffic control device.
Flashing red and yellow light control intersections are typically used to manage traffic flow at intersections where a full traffic signal may not be necessary. A flashing red light indicates that drivers must come to a complete stop and yield to any oncoming traffic or pedestrians before proceeding, similar to a stop sign. In contrast, a flashing yellow light signals caution, allowing drivers to proceed with caution but requiring them to be aware of potential hazards. These controls help enhance safety while facilitating the movement of vehicles and pedestrians.
If your aircraft is on the ground, a steady red light from the control tower light gun means STOP. If you are airborne, a steady red light means to give way to other aircraft, and continue circling.
It tells you to proceed with caution.
Traffic approaching the light is to stop. If the way is clear, traffic can then proceed through the intersection.
