ATC Basics Block 1 Test Quetsions With
Solutions
What is anomalous propagation (A.P.) - ✔️✔ Correct
Answer Beam is BENT because of moisture in the air.
What is temperature inversion? - ✔️✔ Correct Answer Cold air
trapped under warm air. Radar is DEFLECTED
What are the two types of radar jamming? - ✔️✔ Correct
Answer Passive and active
What is passive jamming? - ✔️✔ Correct Answer Dropping
chaff. Mechanical
What is active jamming? - ✔️✔ Correct Answer Electronically
disrupting the radar.
Displays objects in motion - ✔️✔ Correct Answer Movement
target indicator. MTI
,What radar requires no equipment in the aircraft - ✔️✔ Correct
Answer Primary
Focuses, broadcasts, and collects reflected radio energy - ✔️✔
Correct Answer Antenna
Depicts the position and movement of objects that reflect radio
energy - ✔️✔ Correct Answer Radar display
Reduces or eliminates echoes from precipitation - ✔️✔ Correct
Answer Circular polarization. C.P
Normal radar transmission that will cause an echo from anything that
has mass - ✔️✔ Correct Answer Linear polarization. L.P.
Radar indications of aircraft or objects that do not exsist - ✔️✔
Correct Answer False targets
,Appearance of clutter on the radar display caused my moisture in the
air bending the radar beam - ✔️✔ Correct Answer Anomalous
propagation. A.P
Occurs when warmer air is trapped on top of cooler air - ✔️✔
Correct Answer Temp. Inversion. Deflects beam
Appearance of clutter on the radar display that results from two radar
systems operating on similar frequencies - ✔️✔ Correct
Answer Radar interference
Appearance of clutter on the radar display caused by dropping large
amounts of chaff - ✔️✔ Correct Answer Passive radar jamming
Clutter pattern achieved by electronic disruption of the radar
Operating frequency - ✔️✔ Correct Answer Active radar
jamming
Area directly above the antenna that is not included in the signal
pattern? - ✔️✔ Correct Answer Blind zone
, Amplifies and converts reflected radio energy into video - ✔️✔
Correct Answer Receiver
What are the components to secondary radar? - ✔️✔ Correct
Answer Interrogator, antenna, transponder, decoder, radar display
What can sometimes cause false targets? - ✔️✔ Correct
Answer Transponder operating near obstructions, ring around, and
improperly adjusted transponders.
What are some advantages of secondary radar? - ✔️✔ Correct
Answer Less vulnerable to blind spots. it provides a longer range
than primary radar. Not degraded by weather.
What are some disadvantages of secondary radar? - ✔️✔ Correct
Answer Only displays aircraft with transponders.
Does not provide weather information.
