Ch.3 - Radio Procedures Flashcards
Station
A transmitting or receiving radio facility located either on the ground or in an aircraft
Are callsigns permanent
Some are whereas others may alter from fight to flight
What are the three types of aircraft callsigns
- Aircraft registration letters
- Telephony designator and registration letters
- Telephony designator and flight identification
Aircraft registration letters - callsign type
Type of aircraft, followed by the last 3 letters of the aircrafts registration marking
ZK
All aircraft in NZ have a registration that consists of ZK
Telephony designator and registration letters - callsign type
The telephony designator of the aircraft operating agency followed by the last three letters of the aircraft’s registration marking in the phonetic alphabet. For example: KAT-AIR CHARLIE DELTA ECHO.
Telephony designator and flight identification - callsign type
The telephony designator of the aircraft operating agency followed by the flight identification number, e.g. RUSH-AIR 15
Which type of call sign can not be abbreviated
Telephony designator and flight identification
What call signs are only for the use of holders of an Air Operator Certificate
- Telephony designator and flight identification
- Telephony designator and registration letters
Callsign - Control
Area and approach control including area and approach radar
Callsign - Approach
Approach control where provided as a seperate function
Callsign - Arrival
Approach control radar arrivals
Callsign - Departure
Approach control radar departures
Callsign - Tower
Aerodrome control or aerodrome and approach/area control where these services are provided from a control tower
Callsign - Ground
Surface movement control including clearance delivery
Callsign - Radar
Area or approach control radar on a discrete frequency
Callsign - Flight service
AFIS
Callsign - Information
Area Flight Information Service
Callsign - Delivery
Clearance Delivery
Callsign - Radio
Air-Ground Service
Callsign - ATIS
Automatic Terminal Information Service
How are ground stations identified
The name of the location followed by the service available
Callsign - UNICOM
UNICOM service (at unattended aerodromes)
TIBA
Traffic Information Broadcasts by Aircraft
When is TIBA introduced
If significant disruption to ATC or related services occurs
What happens under TIBA procedures
Pilots provide their own separation
Initial call
Made to establish radio communication - callsign of station being called followed by aircraft callsign
Reply to the initial call
Callsign of the station that made the initial call and callsign of station responding
Say again (an item)
Say again the specific item in the message
What must be readback
Clearances and numbers
VFR loss of radio communication
Don’t declare emergency as separation from is possible with a good lookout
IFR loss of radio communication
Declaring an emergency is an option
Loss of communication following procedure
- Fly aircraft
- Squawk 7600
- Maintain separation
- Keep a good lookout
- Carry out onboard checks
Onboard radio checks - loss of communication
- Check masters, avionics, radio ON
- Mic leads IN
- Circuit breakers
- Volume + squelch level
- High ground
Communication failure after onboard checks
- Change frequency
- Change mic
- Relay through other aircraft
- Prefix with transmitting blind
- Fly higher
Controlled airspace loss of radio communication
Follow recent clearance instructions, avoid high traffic areas, divert to unattended aerodrome if possible, if not enter airspace via published arrival procedure, or approach side onto the runway and do an overhead join
How will pilots be advised of TIBA
NOTAM action
Pre-flight radio test
After the radio has been turned on listen to communications with ATS or ATIS broadcasts, if the radio is working no further testing is required, IF ATS isn’t on duty or you are shielded by high ground make a call to ATS after takeoff if there is no response land and investigate the problem
Signal Check
When the aircraft is airborne and radio is ON an in-flight radio check is required
Maintenance check
For a ground test during maintenance
Readability scale
1 (unreadable) - 5 (perfectly readable)
Requesting ground station participation in a radio check
Name of station calling, aircraft callsign, RADIO CHECK ON (frequency)
Requested by a ground station to participate in a radio check
The ground station transmits your aircraft callsign followed by numerals and you respond with your callsign, READING YOU (1-5)
TIBA frequency
If initiated through NOTAM the frequency will be included in the advice, if it is not planned use the primary frequency for that airspace
TIBA listening watch
Maintained 10 minutes prior to entering airspace, or if leaving an aerodrome within the airspace commence ASAP before takeoff
TIBA time of broadcasts
Give as much advance as possible of your intentions, broadcasts should be made 10 minutes prior to entering airspace, ASAP before/after takeoff, 10 minutes prior to crossing a reporting point, 2-5 minutes prior to changing altitude, when at designated altitude, anytime the pilot considers necessary
When to use the speechless technique using unmodulated transmissions
The transmitter is working but the mic is unserviceable but able to be used for unmodulated transmissions
The relay system is not able to be used for flight under what alt
400ft
Where can you find info on LRG VHF frequencies in NZ
FISCOM charts
What should you do if you are unable to contact with an ATS unit due to high terrain
Select LRG frequency and ATS unit for the area Fly at a higher alt Contact other aircraft to relay Transmit blind Use 5592kHz if HF radio is equipped
Speechless technique using unmodulated transmissions ATS procedure
Upon hearing the unmodulated transmission ATS will instruct the pilot to activate the transmitter 3 times and then proceed to ask questions
Unmodulated transmissions YES
Press once
Unmodulated transmissions NO
Press twice
Unmodulated transmissions SAY AGAIN
Press three times
Unmodulated transmissions AT NOMINATED POSITION
Press 4 times
Light signal - Steady green
In-flight - cleared to land
On aerodrome - cleared to takeoff
Light signal - Steady Red
In-flight - give way to other traffic and continue circulating
On aerodrome - stop
Light signal - Green Flashes
In-flight - return for landing
On aerodrome - cleared to taxi
Light signal - Red flashes
In-flight - aerodrome unsafe don’t land
On aerodrome - taxi clear of the landing area in use
Light signal - White flashes
In-flight - land at this aerodrome and proceed to the apron
On aerodrome - return to the starting point on this aerodrome
Light signal - Red and green flashes
In-flight - Danger be on alert
On aerodrome - Danger be on alert
Light signal - Red pyrotechnic
In-flight - Don’t land (notwithstanding previous instructions)
