240KIAS
1.5mins
What is the max IAS and TIMING in a HOLDING pattern above FL200?

What is the circling area for a CAT C aircraft?
How is the circling area determined?
What is the CAT C obstacle clearance?
4.20NM
The circling area is determined by drawing an arc centred on the threshold of each usable runway and joining these arcs by tangents.
400FT
During visual circling, descent below the MDA may only occur when the pilot:
A. Maintains the aircraft within the circling area; and
B. Maintains visibility along the intended flight path not less than the minimum specified on the chart; and
C. Maintains visual contact with the landing runway environment (threshold/approach lighting/other marlins identifiable with the runway); and either
NIGHT AND DAY
D. While complying with A B and C and from a position on the downwind base or final leg not less than MDA can complete a continuous descent to the threshold using normal rates and ensuring obstacle clearance (400FT) until aligned with runway; or
DAY ONLY
E. While complying with A B and C maintains visual contact with obstacles ensuing obstacle clearance of 400FT until aligned with runway
When can a pilot descend below LSALT/MSA?
DONT VECTOR IN VERY CLOSE
- DME or GNSS arrival
- Radar Vectors
- Instrument approach and landing chart
- VMC by day
- Climb after takeoff
What is the the gradient and obstacle clearance for a missed approach?
When must a missed approach be executed?
So NOT VISUAL R O F L
2.5% gradient (152FT/NM)
100FT clearance
So: Straight in/runway landing cannot be affected unless circling can be made with conditions at or better than those specified for approach
Not Visual: visual reference not established by MDA, DA/RA or MAPT for which missed approach procedure commences
R: RAIM warning or loss of RAIM after IAF
O: Aircraft OUT of tolerance during final segment for the aid being used (5degrees NDB/1/2 scale VOR/GNSS)
F: Radio aid FAILS or becomes suspect (below MSA)
L: visual reference is LOST while circling
How long is an Actual QNH valid for when applying the MDA on an IAL?
15 minutes
Is circling allowed in a “no circling” area?
No unless visual by day
What are the tracking tolerances for an NDB and VOR?
NDB: +/- 5 degrees
VOR: 1/2 scale deflection
What are the recency requirements for night flight?
1 night takeoff and landing in aircraft in preceding 90 days; and either
A. Within preceding 90 days 3 night landings and takeoff in aircraft or approved sim; OR
B. Within preceding 180 days performed a proficiency check related to carrying out night operations in simulator.
What are the recency requirements for an instrument approach?
Non precision approach (NDB/VOR): 90 days
Precision approach: (ILS LLZ): 90 days
DGA/RNAV: 90 days
What is the landing minima without an approved instrument approach by day and night?
Day: Visual approach requirements
Night: VMC from LSALT within 3NM
What is the landing minima with a NPA (non precision approach)?
As per the chart UNLESS HIAL is inoperative the LOC visibility minima must be increased by 900m
What is the landing minimum visibility with an approved CAT I ILS?
a. 1.5KM visibility if HIAL inoperative
b. 1.2KM if:
1 - HIRL is available
2 - Aircraft is hand flown using FD or with coupled autopilot (LOC/GP)
3 - aircraft is equipped with AHRS warning system
c 800m if RVR on threshold zone unavailable
Otherwise as on chart
What are the requirements for conducting a visual approach by DAY?
Within 30NM not below LSALT/MSA/DME or GNSS step/MDA and aircraft is established:
- Clear of cloud
- In sight of ground or water
- Visibility not less than 5KM
- Aircraft not descended below minimum for VFR flight (500/1000)
What are the requirements for conducting a visual approach by NIGHT?
Aircraft established now below LSALT/MSA/DME or GNSS step/MDA and:
- Clear of cloud
- In sight of ground or water
- Visibility not less than 5KM
- Within circling area; Or
- Within 5nm (7nm ILS runway) aligned with runway not below on slope (PAPI/T-VASIS) or 10nm (14nm RWY 16L/34L at SY) not below ILS glide path with less than full scale azimuth deflection
What defines a qualifying multi engine aeroplane for takeoff minima?
- Two pilot operated; or
- Single pilot operated jet; or
- A single pilot operated propellor aeroplane with auto feather
Take-off minima for qualifying multiengine aeroplanes (MOS 15.05)
Take-off minima is detailed on the Jeppesen Airport Chart and must never be less than:
In a qualifying multi-engine aeroplane, the
take-off minima are:
› visibility of:
» 800 m, or
» 550 m but only if:
– the runway has illuminated edge lighting at spacing intervals not more than 60m and centreline lighting or centreline markings, all of which are supported by a secondary power supply with a switchover capability of one second or less
– where the aerodrome is non-controlled, or is controlled but without ATC in operation, the take-off is by day and the aerodrome is one where you must carry a radio.
What must a pilot do if a TAF has PROV attached?
A suitable alternate with a firm forecast must be planned
What conditions require the planning of an alternate?
Alternates Could Very Well Price Life Savers
A
Aids:
RPT 2 receivers in air capable of using 1 ground aid; or
2 independent ground aids and 2 receivers capable of using these aids
UNLESS
If no aid at aerodrome not more than SCT cloud below final route LSALT +500FT and 8KM vis
What conditions require the planning of an alternate?
Alternates Could Very Well Price Life Savers
C
Cloud:
Not more than SCT below the alternate minimum
What conditions require the planning of an alternate?
Alternates Could Very Well Price Life Savers
V
Visibility:
Less than the alternate minimum; OR
Greater than alternate minimum but forecast endorsed with prob percentage of vis below alternate minima
What conditions require the planning of an alternate?
Alternates Could Very Well Price Life Savers
W
Wind:
Crosswind or tailwind greater than than aircraft limit (35xw and 15dw for BAe146 -200/-300)
What conditions require the planning of an alternate?
Alternates Could Very Well Price Life Savers
P

Forecast endorsed as provisional
What conditions require the planning of an alternate?
Alternates Could Very Well Price Life Savers
L
Lighting
Alternate required for lighting if:
- PORTABLE LIGHTING with no responsible person
- DEPARTURE: 10mins prior to 30mins after
- ARRIVAL: 30mins prior to taxiing complete - NO STANDBY POWER with no responsible person
- PILOT ACTIVATED LIGHTING with no responsible person
What are the requirements for an alternate aerodrome in regards to lighting?
RPT
- Served by lighting that is NOT PAL
- Served by PAL and there is a responsible person in attendance
NON RPT
- Must carry dual VHF; or
- Single VHF and HF and 30 mins holding fuel to alert ground staff in event of failure of aircraft radios
