kap 4- transfere of communications Flashcards
What is transfer of VHF communications?
An aircraft shall be advised by the appropriate aeronautical station to change from one radio frequency to another in accordance with agreed procedures. In the absence of such adice, the aircraft shall notify the aeronautical station before such a change takes place.
When establishing initial contact on, or when leaving a VHF frequency, an air raft station shall transmit such information as ay be prescribed by the appropriate authority.
What is the procedure for transfer of communication?
a. CONTACT … (freq);
b. AT (or OVER) (time or place) CONTACT (unit call sign) (freq)
c. IF NO CONTACT (instructions);
d. *STAND BY (freq) FOR (unit call sign)
e. REQUEST CHANGE TO (freq)
f. FREQUENCY CHANGE APPROVED
g. MONITOR (unit call sign) (freq)
h. ** MONITORING (freq)
i. WHEN READY CONTACT (unit call sign) (freq)
j. REMAIN THIS FREQUENCY
- an aircraft may be requested to STAND BY on a freq when it is intended that the ATS unit will initiate communications and to “MONITOR” a frequency when information is being broadcast thereon such as an ATIS broadcast
** Denotes pilot transmissio. For transfers of communication within one ATS unit, the call sign of the ATS unit may be omitted, when so authorized by the competent authority.
Test procedures for radio check
- The id of the aeronautical station being called
- The aircraft call sign
- The words “RADIO CHECK”
- The freq being used
ATS replies with
1. the id of the station calling
2. the id of the station replying
3. info regarding the readability of the transmission
What is the readability scale?
1 = unreadable
2 = readable now and then
3 = readable but with difficulty
4 = readable
5 = perfectly readable
What is Issue of Clearance and Read Back Requirements?
- A clearance may vary in content from a detailed description of the route and levels to be flown to a bried landing clearence
- Controllers should pass a clearence slowly and clearly since pilot needs to write it down and wasteful repetition will thus be avoided
- Whenever possible a route clearance should be passed to an aircraft before start up
- Controllers should avoid passing a clearance to a pilot engaged in complicated taxi manoeuvres and on no occasion should a clearance be passed when the pilot is engaged in line up or take- off manoeuvres.
Where are provisions governing clearances contained?
PANS-ATM
What is PANS-ATM short for?
Procedures for Air Navigation Services - Air Traffic Management
What is an ATC route clearance not?
It is not an instruction to take- off or enter the runway
What are the rules regarding the words “TAKE OFF”
The words “TAKE OFF” are used only when an aircraft is cleared for take- off, or when cancelling a take- off clearance. At other times the word “DEPARTURE” or “AIRBORNE” is used. Pilots only use the word TAKE- OFF when acknowledgning their clearance to do so.
What are the read back requirements?
Read back requirements have been introduced in the interests of flight safety and ensures:
- Correct received
- The right aircraft
What shall the controller transmit after an incorrect read back from an aircraft?
“negative”, then followed by the correct version
What to do if there is doubt whether a pilot can comply with an ATC clearance?
advise the controller using the phrase “UNABLE” and give the reason (e.g. due to weight)
What are conditional phrases?
Conditional phrases shall not be used for movements affecting the active runway(s), except when the aircraft or vehicles concerned are seen by the appropriate controller and pilot(s). In all cases a conditional clearance shall be given in the following order and consists of:
1. identification
2. the condition (specify)
3. the clearance
4. brief repetition of the condition
“Arctic 57G, BEHIND 737 on short final, line up behind”
What does ATC want to know if they ask you to “report flight conditions”?
They want to know whether you are flying in Instrument Meteorological conditions (IMC) or Visual Meteorological conditions (VMC). It is not related to turbulence.
