Radio Procedures at Aerodromes

Question 1

Most controlled aerodromes have what?

Answer 1

ATIS

Question 2

what is typically in an ATIS? (14)

Answer 2

• Terminal Info (Name of aerodrome)
• code letter of the transmission (e.g information Delta)
• issued at (time)
• expect … (type of approach e.g visual)
• runway (in use)
• surface conditions
• any other operational information
• surface winds (in degrees magnetic and knots)
• visibility
• present weather
• temperature and dew point
• QNH
• 2000ft wind
• statement “ ON FIRST CONTACT WITH … TOWER/ APPROACH CONTROL (as applicable) NOTIFY RECEIPT OF INFORMATION, e.g BRAVO)

Question 3

when should you listen to the ATIS?

Answer 3

before taxiing or prior to arriving at an aerodrome.

Question 4

what is an unattended aerodrome?

Answer 4

uncontrolled aerodromes that do not have ATC or flight service in attendance.

Question 5

radio transmissions at unattended aerodromes are normally prefixed with what?

Answer 5

name of the aerodrome followed by the word traffic e.g OMAKA TRAFFIC

Question 6

when should you make radio calls at unattended aerodromes? (4)

Answer 6

• prior to taxi
• prior to lining up on the runway for takeoff
• Not mandatory to make calls approaching but you should make a broadcast when below 3,00ft and 5-10NM from aerodrome using position report
• carrying standard overhead procedure for joining, report when overhead aerodrome, the make another broadcast before joining circuit.

Question 7

where are mandatory broadcast zones established?

Answer 7

around some uncontrolled aerodromes where traffic density is high.

Question 8

when must pilots transmit their position and intentions when in an MBZ? (4)

Answer 8

• on entering an MBZ, advise callsign, position, altitude, and intentions
• when joining the circuit of the aerodrome in MBZ, do the same
• before entering the runway for takeoff, advise callsigns, runway used, intentions within MBZ after takeoff
• at specified time intervals prescribed for the MBZ indicated in the text box that identifies the zone on VNC. Advise callsigns, positions, altitude and intentions.

Question 9

what calls are used at MBZ?

Answer 9

the same as unattended aerodromes (TRAFFIC) even when UNICOM services are available

Question 10

at busy MBZ what should happen to reports?

Answer 10

keep them brief. callsign, position, altitude, and direction.

Question 11

where is UNICOM available?

Answer 11

some unattended aerodromes normally with MBZ such as Ardmore

Question 12

what is UNICOM?

Answer 12

a base radio staffed by local qualified persons not AIR NZ

Question 13

what can you obtain with UNICOM?

Answer 13

operational information such as surface wind, location of other known aircraft, and similar items, service can only give information, not direct traffic, specify runway etc.

Question 14

UNICOM services typically include what? (5)

Answer 14

• Basic weather info (wind, visibility cloud cover, temperature, QNH)
• AWIB
• Current aerodrome info and condition
• A base radio service
• A telephone service during published hours

Question 15

what do AWIB at unattended aerodromes serve as?

Answer 15

Similar to ATIS, both provide pre-recorded info on runway-in-use, wind velocity, other meteorological details, and operational information.

Question 16

How do you get AWIB?

Answer 16

some aerodromes you can just select a published frequency on VHF radio, but some you might have to select a published frequency and press the mic transmitter button for a stated number of times, with a stated period of time.

Question 17

what does CFZ stand for?

Answer 17

common frequency zones

Question 18

what are CFZ?

Answer 18

similar to MBZ, where aircraft position, altitude, intentions and any other appropriate info is broadcast.

Question 19

how are CFZ zones marked on VNC charts?

Answer 19

thick blue line and a text box within the area explaining the name of zone, frequency to be used, and vertical extent.

Question 20

whats the difference between MBZ and CFZ?

Answer 20

the difference is that CFZ isn’t mandatory. Good airmanship, however, means full compliance with the information listed in the text box within the boundary of the zone.

Question 21

how is a controlled airspace defined as?

Answer 21

by a type and a class.

Question 22

what are the two types of controlled airspace?

Answer 22

(CTR) Control Zone or (CTA) Control Area

Question 23

in busy controlled places, what extension of controlled airspace can be found?

Answer 23

Terminal Control Area (TCA) at busy airports and Upper Control Area (UTA) located generally above 9500ft

Question 24

what are the classes of controlled airspace?

Answer 24

Class C or D

Question 25

what is the class of uncontrolled airspace?

Answer 25

Class G (no types)

Question 26

In a Class C controlled airspace what is expected for pilots to do in regards to ATS? (5)

Answer 26

• IFR & VFR flights require clearance to enter
• ATC separates VFR flights from IFR
• ATC separates special VFR (SVFR) flights from IFR
• ATC separates SVFR from other SVFR when visibility is less than 5km
• ATC don’t separate VFR from other VFR

Question 27

In a Class D controlled airspace what is expected for pilots to do in regards to ATS?(5)

Answer 27

• IFR & VFR flights require clearance to enter
• ATC separates VFR flights from IFR
• ATC separates special VFR (SVFR) flights from IFR
• ATC separates SVFR from other SVFR when visibility is less than 5km
• ATC don’t separate VFR from other VFR`

Question 28

In a Class G uncontrolled airspace what is expected for pilots to do in regards to ATS?

Answer 28

Aircraft whether VFR or IFR don’t requre a clearance either by day or night, ATC doesn’t separate any aircraft day or night.
