Radar separation only... ?
if identification exists and will be maintained
Apply [non-radar / radar?] separation between aircraft over same holding point.
non-radar
How do you apply separation between en-route and holding traffic?
Apply vertical separation between holding and en-route while en-route acft within 5 minutes of holding area.
Unless lateral separation exists.
How do timed approaches work?
- A suitable point in approach path, which can be accurately determined by the pilot, shall be specified to serve as a checkpoint in timing successive approaches.
- Acft shall be given a time at which to pass the specific point inbound.
- This time shall be determined with the aim of achieving the desired interval between successive landings.
- The applicable separation minima shall be resprected at all times, including period of runway occupancy.
Who defines the time at which acft should pass the specified point in timed approaches?
Approach Control
Each aircraft in the approach sequene shall be cleared to pass the specified point inbound at the previously notified time (or revisions thereof) only .... ?
...after the preceeding aircraft has reported passing the point inbound.
What do you have to take into account considering timed approaches?
- relative speed of acft
- weather conditions
- distance between FAF and airport
- type of approach
What do you have to issue to acft before specifying time to leave approach fix inbound?
time check
Succeeding aircraft shall be cleared for approach when the preceeding aircraft... ?
- has reported that it is able to complete its approach without encountering IMC, OR
- is SICOM (in communication with and sighted by TWR) and reasonable assurance exists, that a normal landing can be accomplished, OR
- las landed
What's the entry procedure form HOC and FRI at WDM (time)?
HOC: 3 min entry procedure
FRI: direct via left turn
What's the entry procedure form HOC and FRI at POL (time)?
both 3 min entry procedure
What are the deemed separations of adjacent holdings FRI - HOC - WIL?
FL160: NO adjacent holdings! only holding at ONE fix
FL150-130: no adjacent holdings HOC-WIL
FL120 and below: adjacent holdings allowed
What are the deemed separations of adjacent holdings FRI - WDM - HOC?
FL160: only holding at ONE fix allowed
FL150 - FL80: holding at FRI and HOC allowed
7000 ft and below: everywhere allowed
What are the deemed separations of adjacent holdings FRI - POL - HOC?
FL160: only holding at ONE fix allowed
FL150 - FL80: holding at FRI and HOC allowed
7000 ft and below: everywhere allowed
What's the non-radar separation between departing acft?
- 1 min; if tracks diverging at least 45° immediately after take-off
- 2 min; if preceeding acft ist 40kts or more faster and both flying same route
- 5 min; while vertical separation does not exist, if departing acft will fly through level of preceeding acft and both fly same route
What information should you pass to arriving aircraft?
- runway-in-use
- current met info (unless included in ATIS)
- runway conditions
- changes in operational status of visual/non-visual aids, essential for approach and landing
Which information do you have to transmit ANYWAY to aircrafts (even if in ATIS)? (APP responsible, mostly delegated to TWR)
RVR and altimeter setting (at least once during approach)
QNH, when first descending below transition level
surface wind (included in landing, t/g or go-around clearance)
What if acft acknowledges no longer current ATIS?
transmit all elements which need update
What are the duties of APP in respect of ATIS?
- transmit elements which need update if acft reports no longer current ATIS
- inform unit responsible (usually tower) of significant changes
Who will normally issue initial clearance for arriving aircraft and how?
ACC, normally via the appropriate STAR
What does APP have to do on initial contact with arriving aircraft?
Amend clearance issued by ACC as necessary and inform about type of approach to be expected.
What if no STAR published?
Describe full route to be flown by arriving aircraft.
Do NOT clear an IFR flight on initial approach below the appropriate minimum altitude (MFA), unless.....? (4)
- acft is conducting visual approach
- position positively determined by radar
- pilot reported passed point defined by radio aid
- pilot reports aerodrome in sight and maintaining in sight
Can we issue approach clearance regardless of weather?
Yes,
it is the responsibility of the pilot to determine whether or not the conditions are below his landing minima.
What information has to be passed BEFORE final approach? (4)
- windshears / turbulences in final approach area
- current visibility in final approach path
- RVRs (if available)
- significant changes of surface wind direction and speed
What information has to be passed DURING final approach? (4)
- sign. variation of current surface wind
- changes of RVR or visibility
- sign. changes of runway conditions
- changes in operational status of visual or non-visual aids
- sudden occurence of hazards
- any other information received by TWR which may affect acft
What do you have to specify if pilot reports or if clearly apparent, that he's not familiar with instrument approach procedure? (6)
- point at which approach procedure will start
- level at which approach procedure will start
- initial approach level
- final approach track
- missed approach procedure (if deemed necessary)
- frequency of LOC
An IFR flight may be cleared for visual approach, provided...?
- able to maintain visual reference to the terrain
- reported ceiling is at or above initial approach level
OR
- pilot reports any time during instrument approach procedure that he can carry out visual approach.
What's the main task of the controller during visual approach?
provide separation and traffic information, according airspace classification
What if you have 2 visual approaches?
- apply non-radar separation until succeeding acft reports preceeding in sight
- instruct pilot to maintain own separation
- issue caution wake turbulence if necessary
