Ch. 6 - Control Airspace Procedures Flashcards
What is controlled airspace defined by
Type and Class
Types of controlled airspace
CTR, CTA, TMA, UTA
CTR
Control Zone
CTA
Control Area
TMA
Terminal Control Area, arranged around busy airports
UTA
Upper Control Area, located above 9500ft
Classes of controlled airspace
C or D
Airspace that touches the earth surface
Zone
Airspace that doesn’t touch the earths surface
Area
Uncontrolled airspace types
No types
Uncontrolled airspace classes
G
When do you contact the ATC unit responsible for the airspace
10 miles from reaching the boundary of the airspace
What class is VFR separated from IFR
C
What class is VFR separated from VFR
None
What class is SVFR separated from SVFR
C and D
What class is SVFR separated from IFR
C and D
What class do you need clearance to enter
C and D
CLEARED … ON TRACK …
Proceed along the track you’ve requested. Read back cleared route.
CLEARED … AT (alt)
You must go to & remain at the cleared altitude. Once at the cleared altitude if you wish to climb or descend, you need to request and obtain an amended clearance. Read back cleared altitudes.
CLEARED … AT OR BELOW (alt)
Which means you can fly at the cleared altitude or any altitude below the cleared altitude. Read back cleared altitudes.
When should you contact ATC to obtain a clearance for entering controlled airspace
10nm from airspace boundary
Items in a clearance request
- Callsign
- Position
- Level
- Intended route
- Destination
- Clearance request
What should you familiarise yourself with before flight
- Airspace boundaries
- Upper + lower limits
- Controlling authority
- Frequencies
- Visual reporting points
If another controller has arranged a clearance on your behalf without you having to request one whose responsibility is it to ensure that a clearance has been obtained prior to entering the controlled airspace
Yours
If you are in controlled airspace and need to request clearance to enter another controlled airspace what must you do
The request is made on the frequency you are currently using, they will then instruct you to contact … control where you will make a position report and again request clearance to enter their airspace
What must you do when you are under the control of an ATC unit that doesn’t have a radar
You must report when you are at the places stated in the clearance, and you must report when reaching and leaving assigned altitudes
SQUAWK …
Set the code as instructed and read back.
RESET SQUAWK … (mode/code)
Reselect the assigned mode/code. used if the controller thinks you have selected the wrong code Read back “RESET SQUAWK 3714”
RESUME OWN NAVIGATION
Is used after the radar controller has vectored you, means that vectoring has finished and you may turn as required to regain you cleared track. You respond with “RESUMING OWN NAVIGATION TO…”
DESCEND/CLIMB TO …
Commence your descent/climb as soon as practicable, your are required to read back these instructions
WHEN READY … (descend/ climb to … alt)
Used by ATC when issuing a clearance to descend/climb, it means that you start your descent/climb to the given altitude when you are ready. You are required to read back these instructions
REPORT YOUR LEVEL
Report your altitude
IDENTIFIED
The radar controller has positively identified which target on the radar screen is your aircraft, you acknowledge using your callsign
FLY HEADING
Turn onto a given heading and follow this heading until ATC advises further, this is used when under radar control, read back headings
CONFIRM SQUAWK
Confirm the Mode A code set on your transponder. Your response would be to check that you have the correct code selected on your transponder and read back this code to the controller
SQUAWK CHARLIE
Set your transponder, so it will transmit your mode c info, do this by selecting alt function
SQUAWK (code and) INDENT
Press indent button, causing your radar symbol to flash so that the controller can identify you , you don’t need to verbally respond
CONFIRM (level) …
Check and report your altitude to the nearest 100 ft
When ATC is checking your Mode C info how close must ATC’s readout be to your actual alt
Within 200ft
If it not possible to comply with instructions what should you do
Request an amended clearance
If you don’t understand what is required of you by ATC what should you do
Advise the controller and ask for a repeat
If you cannot find which frequency to use who should you ask
Flight Information
CHECK ALTIMETER SETTING AND CONFIRM
Check that you have the correct setting on your altimeter subscale (correct QNH set) and report your alt to the nearest 100ft, respond with ALTIMETER …, LEVEL …ft
STOP SQUAWK
Select OFF
STOP SQUAWK CHARLIE WRONG INDICATION
Having tried the previous transmission and procedure to correct a wrong readout of your altitude, it is still not within acceptable limits. It could also be that your altitude readout on the screen is erratic. It is better not to transmit Mode C information rather than have wrong information. To stop squawking Charlie (Mode C) you set your transponder to the ON function.
SQUAWK
Return to normal transponder operation, check that you are using the correct transponder function
SQUAWK STANDBY
Select SBY on your transponder
SQAUWK MAYDAY
Squawk emergency code 7700
When is it a requirement for transponders to be selected to ON or ALT
In controlled and uncontrolled airspace, so radar controllers can identify you and aircraft equipped with ACAS can receive the transponder transmissions and enhance their ability to avoid a collision
When should the transponder be selected to SBY
After engine start and while taxiing to takeoff position
When should the transponder be selected to ON/ALT
Immediately before takeoff and left there during flight
After landing what should the transponder be set to
SBY or OFF
