What is an AIC
Aeronautical Information Circular
A notice containing information which does not qualify for a NOTAM or AIP inclusion.
Examples:
White - Admin - AIP Charges
Yellow - Operational/ATS - Requests not to overfly cultural events/flypasts
Pink - Safety - Helicopter flying in degraded weather conditions
Mauve - UK Airspace restrictions
Green - Maps and charts
What are the three NOTAM codes?
NOTAMN - New
NOTAMC - Cancel
NOTAMR- Replace
What information is in the AIP?
National documents (rules of the air etc)
Supplements
AIP/Amendment service
AICs
Name four of the ICAO technical divisions

What is the definition of Notified
The information is published in the Nation’s AIP or NOTAM
What actions can take place with ATCO licenses pending/after investigation?
Suspension - placing the license or ratings in abeyance with set conditions. Temporary.
Revocation - withdrawing a licence and/or associated ratings. Permanent.
What are the ATCO ratings?
The main qualifications ADI ADV APP APS ACS ACP
What are rating endorsements?
Specialist additions to ratings
SRA PAR TCL AIR GMC GMS OCN
What are licence endorsements?
Specialist additions to licence

Assessor
What is a MOR
Mandatory Occurrence report. Complies with CA939 (legal document)
How should an ATCO file an MOR?
Through the ECCAIRS website (or published ANSP alternative) within 72 hours of incident
An aircraft’s nav lights have failed. What are the restrictions?
- Ac shall not depart at night if there is a failure of required lighting which cannot be fixed or replaced.
- If in flight, ac should land as soon as safely able unless otherwise authorised. Not authorised outside CAS or Class E.
When is an ac considered in flight?
From when the ac first moves under its own power until the moment it comes to rest after landing.
What is the definition of QFE?
Atmospheric pressure at a specified datum (usually aerodrome level). when set, the subscale will read 0 at the datum.
What is the definition of QNH?
Atmospheric pressure at MSL. When set on the subscale, it will read the aerodrome elevation when the ac is on the ground at the aerodrome.
What is the definition of QNE?
Indication on altimeter when ac on the ground at an airfield with 1013 set. Usually used when ac cannot sent 950hPa or below.
What is the definition of Height?
The vertical distance of a level, point or object considered as a point, measured from a specified datum. (QFE in aviation)
What is the definition of Altitude?
The vertical distance of a level, point or object considered as a point measured from MSL
What is the definition of elevation?
The vertical distance of a point of level, on or affixed to the surface of the earth, measured from MSL
What is the definition of Flight Level
Surfaces of constant atmospheric pressure, related to 1013.25hPa. Separated from by specific constant pressure intervals.
What is Transition Altitude?
The altitude at or below which the vertical position of the ac is controlled by reference to altitude. Usually 3000ft in UK but specified distances in aerodrome MATSIIs
What is the Transition Level?
the lowest flight level available for use above the Transition Altitude. At least 1000ft above.
What is the Transition Layer?
The airspace between the Transition Altitude and the Transition level. At least 1000ft in depth. Ac descending through Tlayer will be descending on altitude, ac climbing through will be climbed on FL.
When would a pilot fly IFR?
- in Class A Airspace
- When met conditions preclude VFR or SVFR
What levels are RVSM
FL290 - FL410
What is the RVSM minima?
Suitably equipped ac can fly in RVSM airspace at 1000ft intervals. Outwith and above FL290 the interval is 2000ft.
What is VMC?
Visual Meteorological Conditions
What is IMC?
Instrument Meteorological Conditions
What is the the VMC minima for flying VFR by Day?
At or above FL100 (all airspace) - 1500m/1000ft from cloud, 8km visibility
Below FL100 in all classes - 1500m/1000ft from cloud, 5km visibility
At/below 3000ft AMSL
in Classes B, C, D and E, 1500m/1000ft, 5km visibility
At/below 3000ft AMSL in F/G (uncontrolled) ac Clear of cloud in sight of the surface, 5km flight visibility. If in Class G and flying at less than 140kts, visibility may be reduced to not less than 1500m
How many Oktas in each cloud category?
FEW - 1-2
SCT - 3-4
BKN - 5-7
OVC - 8
What is the requirement for CAVOK?
Visibility 10km or more
No cloud below 5000ft or MSA, whichever is highest
No significant weather in the vicinity of the ad
No CB or TCU present anywhere
What is RVR?
Runway visual Range
The range over which the pilot of an aircraft on the centreline of a runway can expect to see surface markings, runway edge lights or runway centreline lights. Included in METAR when visibility is below 1500m, and minimum value is 50m.
How is RVR measured?
instrument - photo-optical sensors measure the amount of light received from rwy lights for each third of the rwy - requires at least 10% of runway lighting.
Human observer method - counting visible lights and comparing against a table of values.
What is fog?
Suspension of water droplets giving a visibility of less than 1000m
What is mist?
Suspension of water droplets giving a visibility of not less than 1000m
