Chapter 15 Control of Aircraft Flashcards
What are the 4 types of radar service?
- radar control
- approach radar
- radar vectoring
- PAR and SRA (military only)
What must achieved before any radar service?
Ac must be identified
What are the methods of identification?
- geo location
- location relative to a navaid
- lat and long
- geo ref position
- turns through 30 degrees or more
- positive handover from a controller who has previously identified you
What does radar contact signify?
Aircraft has been identified on radar and instructions will be provided until radar service is terminated
When is position info passed to aircraft?
- on radar identification
- on termination of radar service
Where is can radar vectoring be carried out?
In a radar vectoring area (RVA)
On termination of radar service what is given?
Resume own nav and position is given
Are obstacles shown on RVA charts?
Yes
What is the closest an aircraft can come to the edge of a RVA?
Half radar separation or 2.5nm whichever is greater
What type of headings does the controller give?
Magnetic headings
Who is responsible for terrain clearance when being radar vectored?
The controller
When vectoring onto a localiser what is the max closing heading?
45 degrees (mode 1 and 2 = 30 degrees)
Is PAR a precision approach?
Yes
What will be advised if radar contact is lost in the last 2nm?
A missed approach
Who is responsible for obtaining landing clearance if still on approach frequency and when must this be received by?
The approach controller and must be received by 2nm (missed approach if not)
On an SRA approach what is passed to the crew?
Advisory heights and distances
What is the normal radar termination range (RTR) in an SRA approach?
2nm (can be less)
If the RTR is less than 2nm how often are range and advisory heights passed to crew?
Every 0.5nm
If the RTR is 2nm how often are range and advisory heights passed to crew?
Every 1nm
What type of approach is an SRA approach?
Non-precision
What is the latest a landing clearance can be given?
2nm
Is “land after” a clearance to land?
No (it’s a provisional clearance)
What info is passed to crew prior to taxi?
- runway in use
- wind
- qnh
- air temperature (jets only)
- visibility or RVR
- time
What info is passed to crew prior to entering the traffic pattern?
- rwy in use
- wind
- qnh
When do you switch from approach control to aerodrome control?
In the vicinity of the aerodrome
When should atc advise of delays?
When delays are expected to exceed 30 mins
Who is responsible for separation on a visual approach?
Atc
When should an assigned speed be reported to atc by pilots?
- at any position report
- in an initial call after a frequency change
What is the separation from a holding area?
5 mins flying time (unless lateral separation exists)
What can be used as a checkpoint for a timed approach?
A suitable point on the approach path that is capable of being determined by the pilot
What action is required by atc with regards to timed approaches?
To pass to the aircraft a specified point inbound at the previously notified time
What is a definition of a significant change of wind?
Headwind = 10kts Tailwind = 2kts Crosswind = 5kts
(Remember “what’s the time? 10 to 5”)
What is the objective of class f airspace?
To separate of IFR traffic operating on an IFR flight plan
How do you cross an airway and an advisory route?
At right angles and at the appropriate FL
What traffic receive advisory services in advisory airspace?
Only participating IFR traffic
What flights can receive FIS in class f airspace?
All flight if requested
What are the two emergency frequencies?
Air to ground = 121.5
Air to air = 123.45 (used as a backup)
Who must be warned in the case of an emergency descent?
Aircraft in the vicinity (must broadcast the altitude at intervals)
What should you do if you are informed of an emergency descent?
Unless instructed to clear the area:
- maintain hdg and speed in accordance with current clearance
- stand by for further clearances from ATCU
What is the minimum altitude for fuel jettison?
6000ft
Where must fuel jettison be carried out?
- clear of towns and best over water
- clear of CBS
What is a strayed ac?
One that has deviated significant from its intended track or if reports that it is lost
What is an unidentified ac?
One that ATC is aware of but doesn’t know who they are
