30
Which two units/agencies have to be established in a Search and Rescue Region (SRR), and what are they responsible for?
- Rescue Coordination Center: Communication with ATS, contact with vessels, contact with adjacent RCC, MET offices, rescue units, satellite centres etc. - Rescue Unit: Means of locating and assisting at the accident, with aircraft/ships/ground vehicles that are equipped with COMM, rescue personnel, survival equipment etc.
31
True/false: FIS is only given as a service in areas without Air Traffic Control
False: FIS is given in all airspace classes (A t/m G) and ATC is usually responsible for giving FIS. However, ATC is always given priority over FIS.
32
How can you close a flight plan?
In person Radiotelephony Data link to ATS unit at the destination aerodrome
33
What does a controller need to do when the flight crew of an aircraft informs ATC that they have a failure or degradation of an a/c system which can affect the separation minima?
The controller shall take action to establish another type of separation.
34
For longitudinal separation, what is the minimum time over the same point when the preceding ACFT is 20kts faster?
5 min
35
For longitudinal separation, what is the minimum time over the same point when there are frequent position reports?
10 min
36
What are the levels used in RVSM airspace?
FL290 - FL410 (inclusive), 1000 ft vert separation
37
Procedural vertical separation. What are the 3 exepctions for when an a/c can not be cleared to a previous occupied level that has been reported vacating by another a/c?
Severe turbulence known to exist Higher a/c effecting cruise climb (is slow climbing) Difference in performance such that separation may be lost
38
If the preceding a/c is Mach .03 faster, what is the needed time separation?
8 min
39
How can two a/c be lateral separated when making use of a VOR?
At lease one a/c is 15 NM from VOR Other a/c is on a radial that differs at least 15 degrees
40
When can an departing a/c be identified using PSR?
By correlating an observed radar position indication with an a/c which is known to have just departed, identification is established within 1 NM from the end of the runway used.
41
Using the turn method for PSR identification, what is the minimum change in heading?
30 degrees
42
What are the three stages of the SSR identification procedure?
General location of a SSR response or position which is POSSIBLY the a/c concerned Application of an approved identification method to a SSR response or position symbol which is PROBABLY the a/c concerned POSITIVE IDENTIFICATION of the a/c after completion of one or more of the approved identification methods
43
What are procedures to use for identification of an a/c where SSR, ADS-B or MLAT is used?
- Recognition of the a/c identification (call sign) in the label, when a discrete code is assigned. - Direct recognition of a Mode S equipped a/c in label - By transfer of identification - Set a specific code - Squawk IDENT
44
What info is included in the first call an a/c makes to an ATC unit?
- Designation of the station being called - Call sign (if applicable the word "Heavy" - Level, or if climbing /descending the passing level and cleared level - Speed, if assigned by ATC - Additional elements, as required by the appropriate ATS authority
45
What info shall the controller give the a/c when terminating vectoring?
- Instruct the pilot to resume own navigation - Give the pilot the a/c position and appropriate instructions if the current instructions have diverted the a/c from a previously assigned route
46
If your transponder does not work on the a/c, do you still have a TCAS alert?
No, TCAS is working with transponder signals.
47
What is proximity traffic on TCAS?
Any target within 6 NM and within 1200 ft (filled diamond)
48
Below how many ft are all spoken messages inhibited within TCAS?
Below 500 ft AGL
49
Which messages are inhibited below 1450 ft AGL for TCAS?
RA: "Increase Descent"
50
When is the RA: "Descent" message inhibited?
Below 1100 ft AGL
51
Is there a moment when all RA are inhibited?
Yes, below 1000 ft AGL
52
What are the 3 levels of Air Space Management with FUE?
Level 1 - Strategic ASM; national policy and structures Level 2 - Pre-tactical ASM; Day to day allocation of airspace Level 3 - Tactical ASM; Real time use of airspace
53
Can Permanent ATS routes have different base levels depending on time of day?
Yes! But these routes are not part of FUA structure.
54
What is the difference between Danger, Restricted and Prohibited areas?
Danger: activites dangerous to flight (aerobatics, parachuting, etc) Restricted: flight restricted in accordance with specified conditions (artillery firing, aerial gunnery, mil flight training) Prohibited: Flight prohibited (national security areas)
55
What are the three levels of activation of Temporary Segregated Areas (TSA)?
Published Hours: established at level 1; max possible activation time and published in AIP or by NOTAM Planned Hours: Decided at level 2; planned user time within published hours, published as Airspace User Plan (AUP) Real Activation Times: Activated at Level 3; actual user time within planned hours; ATC operations
56
What are the categories of Conditional Routes (CDR)?
Category 1: permanently plannable during times published in AIP Category 2: non-permanently plannable; typically through FUA that is seldom available to GAT, made available for flight planning at least 1 day in advance, allocated for use at ASM level 2, published in daily AUP Category 3: Non-plannable; typically through FUA that is seldom available to GAT, made available on short notice (less than 1 day in advance), allocated fur use at ASM Level 3 (ATC units)
57
When 2 a/c are separated lateral over a Dead reckoning point, can one of the a/c be inboud?
No, dead reckoning can only be used when both A/C are outbound from the point.
58
An AFTM service shall be implemented...
Where traffic demand at times exceeds the defined ATC capacity
