Intro Flashcards
What frequency bands is VOR / ILS localiser
108 - 118mhz
What frequency range is voice comms
118-137mhz
What affects range of vhf
Power Line of sight Terrain Ducting (super refraction) Obstructions
How does atmosphere affect vhf
Transmissions degraded by moisture in atmosphere
Absorbed or scattered by:
Rain / fog/ snow/ hail/ humidity
Greater at High frequencies
What is the distance between different frequencies
8.33 kHz
If you can’t select a frequency or have 8.33khz between a frequency above FL195 what do you say
“Negative eight POINT three three”
When do you not need to pronounce all digits of a frequency
When final 2 digits are 0
What is time normally given as
Just the minutes
Sometimes hours and mins of confusion
What is a time check
Time given by atc to nearest half min
When should the word “immediately” be used
Safety reasons
What is the readability scale
1 = unreadable 2= readable now and then 3= readable with difficulty 4= readable 5= perfectly readable
What requires a read back
Pressure settings Transition level Clearances / instructions (taxi and runway) Frequencies Transponder settings Heading / speed / level VDF (direction finding) information Type of service
What are the 3 types of call sign
Registration (with aircraft type)
Telephony designation plus reg (easy -EZAS)
Designator plus flight ID
When is heavy csllsign used
MTOM greater than or equal to 136,000kg
What ways can you abbreviate your callsign
First letter and last 2/3 letters of ac reg
“G-wavv” > “g-vv”
Designator plus last 2/3 of reg
“Speedbird vv”
Designator plus flight ID = no abbreviation
“ZK-CTC” > “X-TC”
When can you change callsign mid flight
Only atc can request it temporarily
Changes back to original on frequency change
How can “Heathrow tower” be abbreviated
Either “Heathrow” or “tower”
What is said for general broadcasting
“All stations”
What is the difference between “arrival” and “approach”
Arrival = approach control radar arrivals Approach = approach control
What is said to unattended aerodromes
“Coventry traffic”
What happens if you are told to frequency change with either “contact” “standby” or “monitor”
Contact = call up and contact Standby = someone will contact you Monitor = just listen
What does atc say if you need to abort take off
Before you move:
Atc; “cancel take off”
Pilot: “holding”
Have take off power set/ are moving;
Atc; “stop immediately”
Pilot: “stopping”
What services are available inside controlled airspace
Flight info service (traffic info)
Alerting service (traffic avoidance)
Radar control service (levels and headings)
What services are available outside controlled airspace
Flight info service (info)
Radar info service (alert to traffic)
Radar advisory service (levels / headings)
