Visual signals and NORDO aircraft Flashcards
Since NORDO aircraft cannot communicate via radio, they must receive clearance using this method before landing at a controlled aerodrome.
What are visual signals?
When approaching the traffic circuit, NORDO pilots should enter from this side of the runway before joining crosswind at circuit height.
What is the upwind side?
This is the part of the landing pattern where a plane flies parallel to the runway with the wind behind it, and approaching aircraft from the upwind side should join it halfway down the runway.
What is the downwind leg?
If a flight needs to cross the airport before joining crosswind, it should do so at this minimum altitude above circuit height.
What is 500 feet?
Before turning onto this leg of the circuit, a pilot must check for any aircraft on a straight-in approach.
What is the final approach?
A NORDO aircraft will receive landing clearance at this stage of the approach.
What is final approach?
If landing clearance is not received, a NORDO pilot must take this action unless there is an emergency.
What is pulling up and making another circuit
After landing, a NORDO aircraft does not need this type of clearance unless crossing a runway or taxiing back to a turn-off point.
What is taxi clearance?
If a NORDO aircraft’s landing roll carries it past the last available turn-off point, it should take this action.
What is taxi to the end of the runway and wait for instructions?
A NORDO aircraft receiving this light signal from the tower is cleared to land.
What is a steady green light?
A NORDO aircraft seeing this light signal must give way to other aircraft and continue circling.
What is a steady red light?
A NORDO aircraft receiving this light signal should return for landing, but must wait for further clearance.
What is a series of green flashes?
A NORDO aircraft receiving this light signal should not attempt to land because the airport is unsafe.
What is a series of red flashes?
Whether by day or night, this visual signal overrides any previous instructions and means “do not land.”
What is the firing of a red pyrotechnical light?
A NORDO pilot should acknowledge clearances and instructions in flight during a day flight by performing this maneuver.
What is a distinct rocking of the aircraft?
At night, a NORDO pilot acknowledges visual signals by using this method.
What is a single flash of a landing light?
Before moving onto the maneuvering area of a controlled airport, a NORDO pilot must inform the control tower of their intentions and arrange for these.
What are visual signals?
Before operating within a control zone with Class C airspace, a NORDO aircraft must obtain this from the control tower.
What is a clearance?
A NORDO aircraft should maintain this minimum distance from the edge of any runway if holding position markings or signs are not visible or established.
What is 200 feet?
When stopped by this visual signal, a NORDO pilot must wait for further clearance before proceeding.
What is a steady red light?
A NORDO pilot may attract the attention of the airport controller when ready for takeoff by day by performing this action.
What is turning the aircraft toward the tower?
A NORDO pilot acknowledges visual signals on the ground by fully moving these control surfaces, repeating the motion at least three times.
What are rudder or ailerons?
A NORDO aircraft receiving this light signal is cleared to taxi.
What is a series of green flashes?
