Communications Flashcards
What is meant by RFT (or R/T)?
Radio Telephony
Review 2 (Page 53) table to review phonetic alphabet.
Back of Book
The VHF radio frequency band is from ….. to ….. MHz.
30 - 300 MHz
What is MHz?
Megahertz - signal frequency in millions of cycles per second.
Should the squelch be set at minimum or maximum or somewhere in between.
In between - to respond to signals without admitting excess hash.
What is amplitude?
The magnitude of the peaks and troughs of an oscillation.
What significance does the word MAYDAY have?
The international prelude to distress message.
Is the transmit button the same thing as the PTT?
Yes
Why have a transmit button on the control column?
So the pilot’s hands remain free to control the aircraft while transmitting.
Say ATC in phonetics.
Alpha Tango Charlie.
What transponder mode do set for circuit operations.
Standby.
If the radio fails completely in the circuit area, what would you do?
Continue a normal circuit, make normal transmissions, look for a green light on final approach, look for traffic on the runway.
What do the letters ELT stand for?
Emergency locator transmitter.
What is the significance of VHF COM versus VHF NAV?
VHF COM is the radio transmitter/receiver. VHF NAV is navigation (VOR) receiver.
About how far can you expect to receive VHF transmissions from an altitude below 5000 feet.
60 nm maximum.
Say IHTFP in phonetics.
India Hotel Tango Foxtrot Papa
What are the pros and cons of a hand-held microphone versus a headset?
There are no pros for the hand-held. It is a back-up only.
If another aircraft says “how do you read me” and the transmission is feint clarity is blurred, what numbers, in regard to readability, would you choose?
Strength 2 readability 3.
Why should we select STBY when changing transponder codes.
Otherwise there are spurious transmissions as it passes through other selected codes.
If the oil pressure drops slowly, would you declare and emergency and, if so, what call would you make?
Not if all other indications were normal. I would turn for home and if there were any unusual indications a pan-pan would be declared.
If the radio fails completely in the training area, what would you do.
Return via normal reporting points and lanes of entry. Make normal calls. Select 7600 on the transponder. Enter the circuit form 500ft above on the dead side and look for traffic.
In the event of no noise whatsoever in your headset, what actions/checks would you undertake.
Reset the connections. Check radio and intercom turned on volumes and squelch adjusted. If still quiet try the hand held mic.
What is the international VHF distress frequency?
121.5 MHz.
If an aircraft is called to be in your left, seven o’clock high. Where exactly is it?
Check page 54 for pic.
Over your left shoulder - nearly behind.
What do you do if you are on final and see a red light from the control tower.
Go around for another circuit.
