Aviation Law 2 Flashcards
Define Aerodrome
A defined area (including any buildings, installations and equipment) on land or water or on a fixed off- shore or floating structure, intended to be used either wholly or in part for the arrival, departure and surface movement of ACFT
Define Runway
A defined rectangular area on a land aerodrome prepared for the landing and take-off run of ACFT along its length
Define Taxiway
A defined path on a land aerodrome established for the taxiing of ACFT and intended to provide a link between one part of the aerodrome and another
Including
- ACFT Stand Taxilane - A portion of an apron designated as a TWY and intended to provide access to ACFT stands only
- APN TWY - A portion of a TWY system located on an APN and intended to provide a through taxi route across the APN
- Rapid Exit TWY - TWY connected to a runway at an acute angle and designed to allow landing aeroplanes to turn off at higher speeds than are achieved on other exit TWYs thereby minimising RWY occupancy times
Define Apron
A defined area, on a land aerodrome, intended to accommodate ACFT for the purposes of loading or unloading passengers, mail or cargo, fueling, parking or maintenance
Define Manoeuvring Area
That part of an aerodrome to be used for the TKOF, landing and taxiing of ACFT, excluding the APNs
Define Movement Area
That part of an aerodrome to be used for the TKOF, landing and taxiing of ACFT, consisting of the manoeuvring area and the APN(s)
Different types of RWY
- Cross RWYs
- Parallel RWYs
- Parallel Offset RWYs
- Independent Diverging RWYs
What is considered when determining the RWY in use?
- Surface wind (if light & variable consider 2000ft wind)
- Traffic pattern
- RWY lengths/landing runs
- Availability of approach aids
- Manoeuvring area serviceability
- Aerodrome lighting
- Weather
N.B. STRAMAW
How are aerodromes classified?
- Civil (Controlled or uncontrolled)
- Military (sometimes called government)
- International aerodromes fly to foreign territories and require customs and immigration on site
- Regional aerodromes operate within same territory
What is a controlled aerodrome?
Any aerodrome at which an air traffic control service is provided, regardless of whether or not a control zone (CTR) exists
What is an uncontrolled aerodrome?
- No control
- Aerodrome Flight Information Service (AFIS)
- AGCS (UK), Unicom or other non-ATS as prescribed by the state
- No service
In a VFR traffic circuit, when is it mandatory to report your position?
Downwind and Final
Define Holding Fix
A geographical location that serves as a reference for a holding procedure
N.B. May be over a point source nav-aid (e.g. NDB or
VOR) or be defined as an intersection of VOR
Radials or as a VOR/DME position.
Define Holding Procedure
A predetermined manoeuvre which keeps an ACFT within a specified airspace while awaiting further clearance
N.B. Located to ensure ACFT remains clear of ground and obstructions, ready to continue flight when authorised to do so
What is a Non-published Hold?
ACC controllers may instruct ACFT to hold along ATS routes or within defined controlled airspace
N.B. May be required due to congestion. ATCO to determine inbound axis and direction of the hold.
Reasons for holding?
- Weather
- Traffic management
- Accident at airfield
- Etc
N.B. ACFT should be advised of anticipated delay as early as possible in event of extended delays
Label the following diagram of a standard holding pattern
Define Holding Axis
The required inbound track to the holding fix
N.B.If this is defined by VOR radials, then the axis must lie on one of the radials although it may be orientated towards or away from the relevant VOR
How are turns made in a holding pattern?
- Turns are made at Rate 1 (3º / sec) or with 25º of bank, whichever requires least angle of bank
- ACFT holding at greater than 170 kts may therefore turn at less than 3º / sec
Holding speeds
What are the ACFT Categories?
- Cat A = Less than 91 knots IAS
- Cat B = 91 to 120 knots IAS
- Cat C = 121 to 140 knots IAS
- Cat D = 141 to 165 knots IAS
- Cat E = 166 to 210 knots IAS
N.B. For purposes of instrument approaches and obstacle clearance criteria, ACFT categorised by velocity at threshold which is defined as 1.3 x the stalling speed in landing configuration at maximum certificated landing mass
Define Outbound Leg
- Normally 1 minute, or 1.5 minutes above 14,000ft
- Timing commences either abeam holding fix or on completion of outbound turn, whichever is later
- Where DME available, limiting range for outbound leg may be specified
- Limiting radial may also apply
Entry Procedures
- Sector 1 - Parallel entry (Allow 3 minutes)
- Sector 2 - Offset entry (Allow 3 minutes)
- Sector 3 - Direct entry (No time penalty)
What are 3 other methods of entry of a holding pattern?
- Along holding radial
- Via a DME arc
- Via a secondary fix
What factors affect a holding pattern?
- Wind
- Speed (rates of turn)
- Effect of level (temp and pressure)
- Effect of navigation aid in use
- Turbulence
What could be the effect of different navigation aids on a holding pattern?
Slant range error
Who is responsible for countering wind effect within a hold?
Pilots
Pilots are given awareness of delays causing holds. How is this done?
Using Expected Approach Time and Expected Onward Clearance Time
What is an EAT?
Expected Approach Time
- Time at which approach control expect to leave the hold to commence an instrument approach
- Determined for an arriving ACFT that will be
subjected to a delay of 10 minutes or more (or such other period as has been determined by the appropriate authority)
N.B. When ATC specify a time to leave the holding pattern, the pilot will adjust his timing within the pattern in order to leave at the specified time
What is an expected onward clearance time?
Time to leave hold to continue en-route
N.B. When ATC specify a time to leave the holding pattern, the pilot will adjust his timing within the pattern in order to leave at the specified time
What is normal separation from a holding pattern?
5 minutes flying time from the flight path of the holding ACFT
What is needed for separation from a holding pattern to be calculated?
- ATC need to be aware of dimensions of holding patters
- Authority will calculate and determine which of the adjacent holding patterns can be deemed as separated
- Secondary area around holding pattern is protected
What is a VRP?
Visual Reference Point
N.B. Outside of controlled airspace, no holding over VRPs. Does not apply in controlled airspace where know traffic environment exists
In controlled airspace, where may VFR flights be instructed to hold?
Over VRPs
Who calculates and issues EATs (Expected Approach Times)
Approach control
How are EATs expressed?
- Based on landing intervals
- Expressed as actual times
- Revised as often as required until ACFT leaves holding facility
- Passed to ACFT well in advance
To commence approach sequence…
- Maximise traffic for minimal delay
- Issue EATs
- Keep stepping ACFT down to be ready when cleared
- Lowest level to hold? Check Transition level strip and leave room for Missed Approach Procedure!
- Apply vertical separation (Wait till 1 landed before second one leaves fix)
- Think landing interval
What does the following symbol mean
No delay expected
What reasons could be given for delay not determined in a holding pattern
- ## ACFT holding ahead for weather improvement
