More FROL Flashcards
What are the three radio transmissions
Reports: Made to specific ATS
Broadcasts: transmissions to all stations (prefixed with all stations)
Calls: Made to specific stations
What frequency band does the VOR operate in?
112.0-117.95
What frequency band(s) do NDB operate in?
200-430 kHz
When operating in a radar environment, what mode should the transponder be set to?
ALT
What freq band does the military use
UHF
UTC to EST is?
+ 10 hrs
UTC to ESuT is
+11 hrs
UTC to CST is
+9 hrs 30min
UTC to WST is
+ 8 hrs
When must you read back an assigned code?
always
What does “squawk charlie” mean
put the XPDR on ALT
Of all the transponder instructions given by ATC, which ones are read back?
Only squawk codes
why should we set the XPDR to STBY when switching codes?
to avoid inadvertently activating any of the emergency codes
How would a radio check be done?
“Moorabbin ground
Echo Oscar Delta
Radio check on wun wun niner dayseemal niner”
If a message was sent to you but you didn’t hear it fully/were busy, how would you ask for it to be repeated?
“Echo Oscar Delta
Say again”
Unless otherwise designated, all uncontrolled airspace is
class G
What are FIAs?
Flight Information Areas
What is CTAF
Common Traffic Advisory Frequency
Informs pilots as to what the correct frequency is
What is the MULTICOM
126.7
Used when no CTAF is available
In what places is the carriage and use of a radio mandatory when the tower is closed
Class C and MIL aerodromes
what are broadcast areas
areas within class G that have CTAF assigned
What is the Surveillance Information Service
traffic advice on other known traffic that may conflict with your flightpath
When should clearance into controlled airspace be given to the SIS frequency
5-10 min before entering the airspace
What code letter is used for the ATIS outside of hours
ZULU
What is FLIGHTWATCH
Gives latest weather information for a local area
Where MUST aircraft be radio equipped
CERT, REG or MIL
Are non-radio aircraft allowed to operate at a CTAF aerodrome
yes
In terms of AFRU, how long must no transmission have occurred for there to be a generated response
5 min
when is a beep triggered on the AFRU
When there was a transmission in the last 5 minutes
when do you have to amend you SARTIME
When you change your flight plan
If you need to make a distress call and there is no response after multiple attempts, what frequency should you broadcast on
121.5 (international emergency frequency)
what two frequencies does an analogue ELT simultaneously transmit on?
121.5 and 243 MHz
what frequency can a digital ELT operate on
406 MHz
Why does turning to the left or right sometimes help with improving radio signal
because the airframe itself can actually cause interference
Non-directional Beacons utilise what frequency
Low and Medium frequencies
Global Navigation Systems operate under what frequency
Very Low Frequency
why are repeater stations unsuitable for VHF
because VHF systems rely on there being only one source from one ground station
during the day, what can the thickness of the ionosphere be
50-500km
during the night, what can the thickness of the ionosphere be
100-400km
As a general rule for HF,the closer the station……..
the lower the most suitable HF frequency
waves that actually travel in contact with the earths surface are known as…
surface waves
