Chapter 5 Section A Test Guide

Unless otherwise authorized, if flying a transponder equipped aircraft, a pilot should squawk which VFR code?

1200 The transponder code for standard VFR is 1200. Code 7700 is to communicate an emergency and 7600 is for two-way radio communications failure

If air traffic control advises that radar service is terminated when the pilot is departing Class C airspace, the transponder should be set to code

1200. When radar service is terminated, you no longer squawk a discrete code and should switch to the standard VFR code of 1200.

When making routine transponder code changes, pilots should avoid inadvertent selection of which code?

7500 Avoid inadvertent selection of transponder codes that set off alarms at ATC facilities. These codes are: 7500 for hijacking, 7600 for two-way radio communications failure, and 7700 for other emergencies.

The automatic dependent surveillance-broadcast (ADS-B) system includes what primary components?

ADS-B ground station; aircraft GPS receiver, ADS-B Out transmitter, and ADS-B In receiver. The ADS-B system depends on accurate GPS positions transmitted from each aircraft-GPS is a core component. The ADS-B Out transmitter in your aircraft sends your GPS position to ATC through the ADS-B ground station, which transmits information back to aircraft through the ADS-B In receiver.

An ATC radar facility issues the following advisory to a pilot during a local flight: "TRAFFIC 2 O'CLOCK, 5 MILES, NORTHBOUND..." Where should the pilot look for this traffic?

Between directly ahead and 90° to the right. The pilot's 12 o'clock position is directly ahead, and the 3 o'clock position is 90° to the right. The 2 o'clock position is approximately 60° right.

You can obtain pilot reports and updated weather information along your route of flight by contacting

Flight Service. Flight Service provides all non-ATC services to pilots before and during flight. Hazardous in-flight weather advisory service (HIWAS) provides automated inflight weather advisories over selected VORS, but that service is limited to specific weather products and does not replace preflight or inflight weather briefings from Flight Service. UNICOM is a privately owned air/ground communication station. UNICOM advisories usually include wind direction and speed, favored runway, and known traffic.

During ground operations, from whom should a departing VFR aircraft request radar traffic information?

Ground control, on initial contact. Request radar traffic information by notifying ground control on initial contact with your request and proposed direction of flight. At airports in Class B or C airspace, you might make this request from clearance delivery. Flight Service does not provide radar services and requesting radar service from the tower just before takeoff could delay your departure.

An ATC transponder was tested and inspected on March 15, 2018. The next test is due on

March 31, 2020. An ATC transponder must have been tested and inspected within the preceding 24 calendar months, or its use is not permitted.

An ATC radar facility issues the following advisory to a pilot flying on a heading of 360°: "TRAFFIC 10 O'CLOCK, 2 MILES, SOUTHBOUND..." Where should the pilot look for this traffic?

Northwest Because the pilot's 12 o'clock position is north, the 10 o'clock position is northwest.

When should you activate the IDENT function on your transponder?

On ATC request. Press the IDENT button or softkey on your transponder system only when ATC asks you to "Ident."

(Refer to Figure 52.) Which type radar service is provided to VFR aircraft at Lincoln Municipal?

Sequencing to the primary Class C airport, traffic advisories, conflict resolution, and safety alerts. The VFR services provided within a Class C airspace area include: • Sequencing for all arriving aircraft to the primary Class C airport. • Traffic advisories and safety alerts between VFR aircraft. • Traffic advisories and conflict resolution (radar targets do not touch or 500 feet vertical separation) between IFR and VFR aircraft.

An ATC radar facility issues the following advisory to a pilot flying on a heading of 090°: "TRAFFIC 3 O'CLOCK, 2 MILES, WESTBOUND..." Where should the pilot look for this traffic?

South. Because the pilot is heading east, the 3 o'clock position is to the right, which is south.

What happens when you activate the IDENT function on your transponder?

The transponder return from your aircraft momentarily blossoms on the ATC display to enable easy identification. Pressing the IDENT button or softkey on your transponder system causes the transponder return to blossom on the ATC display and enables easy identification of your aircraft. It does not cause any change to the data block or zoom level on the ATC display.

What basic terminal radar services does ATC provide to VFR aircraft?

Traffic advisories, safety alerts, limited vectoring, and, in Class B airspace, separation between all aircraft. Basic radar service for VFR aircraft provides safety alerts, traffic advisories, and limited vectoring on a workload-permitting basis. In Class B airspace, ATC provides sequencing and separation for all aircraft. In Class C airspace, ATC provides sequencing for all aircraft and separation of VFR aircraft only from IFR aircraft; not other VFR aircraft.

Automatic dependent surveillance-broadcast (ADS-B) provides what services?

Traffic information service-broadcast (TIS-B) through your ADS-B Out transmitter and ADS-B In receiver. The ADS-B ground station receives the position that each aircraft transmits through ADS-B out, integrates it with non-ADS-B radar targets, and transmits the complete traffic picture back to aircraft. Properly equipped aircraft receive the traffic information broadcast through their ADS-B In receivers. Aircraft equipped with ADS-B In and Out can also receive traffic information directly from other aircraft, but this capability is not the same as the TCAS system that is required on airliners.

An ATC radar facility issues the following advisory to a pilot flying north in a calm wind: "TRAFFIC 9 O'CLOCK, 2 MILES, SOUTHBOUND..." Where should the pilot look for this traffic?

West. The pilot's 12 o'clock position is north, so the 9 o'clock position is west.

ATC advises, "traffic at your 12 o'clock." This advisory is relative to your

ground track. Controllers can see the ground track of an aircraft on radar, but cannot factor in any crab angle applied for wind correction. You must consider this when interpreting ATC traffic advisories.

Automatic terminal information service (ATIS) is the continuous broadcast of recorded information concerning

noncontrol information in selected high- activity terminal areas. ATIS is broadcast at certain busy airports, and provides noncontrol weather and runway information.

ATC issues a safety alert to aircraft under their control

that are at an altitude believed to place the aircraft in unsafe proximity to terrain or obstructions. The types of safety alerts are: • Terrain or obstruction alert-immediately issued to an aircraft under ATC control if ATC is aware that the aircraft is at an altitude believed to place the aircraft in unsafe proximity to terrain or obstructions. • Aircraft conflict alert-immediately issued to an aircraft under ATC control if ATC is aware of an aircraft not under their control at an altitude believed to place the aircraft in unsafe proximity to each other. ATC does not provide convective thunderstorm avoidance assistance unless a pilot requests it and ATC agrees to provide the service based on workload.

Absence of the sky condition and visibility on an ATIS broadcast indicates that

the ceiling is at least 5,000 feet and visibility is 5 miles or more. ATIS is broadcast at certain busy airports, and provides noncontrol weather and runway information. If the ceiling is at least 5,000 feet and visibility is 5 miles or more, reporting of the ceiling/sky condition, visibility, and obstructions to vision is optional.

TRSA service in the terminal radar program provides

warning to pilots when their aircraft are in unsafe proximity to terrain, obstructions, or other aircraft. Terminal radar service areas (TRSAS) are airspace areas surrounding about 30 U.S. airports that offer radar services, but where contact with ATC is not mandatory outside of the Class D airspace. TRSA provides basic radar service, including safety alerts-warnings to pilots when their aircraft are in unsafe proximity to terrain, obstructions, or other aircraft. In addition, TRSA service provides sequencing for participating VFR aircraft to the primary airport. Separation is provided between IFR aircraft, not all aircraft.
