Q

How does primary radar work?

A

On the echo principle, meaning that some of the energy is “reflected” back to the antenna. Distance is measured based in time back lapsed between transmission and reception of reflection.

Q

What are the limitations of primary radar?

A

Bending of radar pulses due to atmospheric temperature inversions…toward the ground results in ground clutter. Also precipitation or heavy clouds can block returns. Size of radar returns impacted by surface area of aircraft and finally it does not provide altitude information.

Q

What’s the general manner in which a transponder works?

A

The transponder receives a coded signal from the ATCRBS which causes it to reply automatically with a specific coded signal. This produces a distinctive return on the controllers radarscope.

Q

What is ARTSlll?

A

The Automated Radar Terminal System used by most ASR facilities. This radar display shows primary and secondary returns as well as computer generated alphanumeric data including the aircraft call sign, altitude readout, and ground speed.

Q

What is the ARSR?

A

Air Route Surveillance Radar is the long range radar system that displays traffic in controlled airspace. There are about 100 ARSR facilities to relay traffic information to controllers throughout the country. The stations can detect traffic within 200 miles of the surveillance site.

Q

What is the TRSA?

A

Terminal Radar Service Area provides basic radar service as well as sequencing of all IFR & participating VFR aircraft to the primary airport. The purpose of this service is to provide separation between all participating VFR aircraft and all IFR aircraft in the terminal area.

Q

What is ATIS?

A

Automated Terminal Information Service is a continuously broadcast information service that provides the current observed conditions of the airport. It includes: the time of the report, ceiling, visibility, obstructions to visibility, temperature, dew point, magnetic wind direction & velocity, altimeter setting, ILS approach and runways in use. Each ATIS report is succeeded by an assigned phonetic alphabet to distinguish reports.

Q

What is Clearance Delivery?

A

A facility established at busy airports for ATC to relay IFR clearances to departing IFR traffic. In some instances VFR will be asked to contact Clearance delivery to improve controllers ability to coordinate traffic.

Q

What is ground control?

A

An ATC function for directing the movement of aircraft and other vehicles on the airport service. You must obtain clearance from ground control before leaving the parking area.

20
Q

What is a hover taxi?

A

Move the helicopter below effective translational lift and in ground effect…fast walk at about 3ft off the ground.

21
Q

What is an air taxi?

A

Moving the helicopter above ground effect and up to 100 AGL at a speed determined to be safe by the pilot.

22
Q

What is Departure Clearance?

A

Service provided by ATC after your departure clearance has been approved. Typically radar contact will be confirmed and flight following provided until you clear the terminal airspace.

23
Q

What is Approach Control?

A

An ATC function that provides separation and sequencing of inbound aircraft. It provides traffic advisories or safety alerts when necessary. Should be contacted while still outside of the terminal airspace.

24
Q

What should you do first if you experience a radio failure?

A

Check radio frequency, volume and headphone volume to ensure it’s not a setting problem.

25
Q

Once you’ve established a communication failure isn’t setting related what should you do?

A

Set the transponder to 7600 to signal to ATC you are experiencing a communications failure. Continue transmitting in case ATC is still receiving your transmissions.

26
Q

What does a steady green light mean while in flight?

A

Cleared to land.

27
Q

What does a flashing green light mean while in flight?

A

Return to land…followed by a steady green light.

28
Q

What does a steady red light mean while in flight?

A

Give way to other aircraft and continue circling

29
Q

What does a flashing red light mean while in flight?

A

Airport unsafe, do not land.

30
Q

What does a flashing white light mean while in flight?

A

No assigned meaning.

31
Q

What does a alternating white and red light mean while in flight?

A

Exercise extreme caution

32

What does a steady green light mean while on the ground?

A

Cleared to take off.

33
Q

What does a flashing green light on the ground mean?

A

34
Q

What does a steady red light mean while on the ground?

A

Stop

35
Q

What does a flashing red light while on the ground mean?

A

Taxi clear of landing area, runway in use.

36
Q

What does a flashing white light mean while on the ground?

A

Return to starting point on airport.

37
Q

What does an alternating red and white light mean while on the ground?

A

Exercise extreme caution

38
Q

During the day, how should you acknowledge light signals from the tower?

A

By rocking the helicopter.

39
Q

How should you acknowledge light signals from the tower at night?

A

By flashing your landing or navigation lights

40
Q

What is the definition of Distress according to AIM?

A

The condition of being threatened by serious and imminent danger that requires immediate assistance.

41
Q

What is the definition of Urgent according to AIM?

A

A condition of being concerned for your safety and requiring timely, but not immediate assistance.

42
Q

What transponder frequency should be used during an emergency?

A

7700

43
Q

What radio frequency should be used during an emergency?

A

121.5 MHZ

44
Q

When should the term “MAYDAY” be used?

A

During a distress call.

45
Q

When should the term “PAN-PAN” be used?

A

During a situation of urgency.

46
Q

What are the four “C”s to follow when lost?

A

Climb, Communicate, Confess, and Comply.

47
Q

What is the ELT?

A

The Emergency Locator Transmitter is a battery operated transmitted that is activated with crash generated force automatically and should operate for 48 continuous hours transmitting a distinctive tone on 121.5 MHZ and 243.0 MHZ. It’s used to aide in Search and Rescue of downed aircraft.
