What is above the London and Scottish FIRs? (Flight Information Regions)
Above this airspace is the upper airspace (UIR) or upper information region
What classes of airspace are controlled?
A,B,C,D and E
What classes of airspace are uncontrolled?
F and G
What is the highest class of airspace?
Class A
What is a CTR? (A Control Zone)
an area around some aerodromes where ATC is provided to all flights.
It extends from ground level to a specified level with a minimum lateral dimension of 5nm.
What is a Terminal control area?
Where controlled airspace meet in the vicinity of one or more major aerodromes (class A-E above 6000ft amsl, class E below)
What is a Control Area? CTA
Airspace where ATC is provided and which extends from a base altitude to an upper Flight Level.
What is an airway?
A control area in the form of a corridor with an identification code, deliniated by radio navigation aids.
It extends 5nm each side of a straight line joining certain places, with vertical limits.
What does a controlled airspace look like?
AIRWAY |
|terminal control area|
|CTR|
What class of controlled airspace are airways?
They are all Class A unless they run through a TMA (terminal control area) , CTA (control area) or CTR (control zone) of lower status.
Is class A available for VFR flights?
No
Is class B allocated in the UK?
No
Where is class C airspace?
At FL195 (19,500ft) and above
Where are VFR flights in controlled airspace usually confined to?
Class D and E airspace
What controlled airspace can be seen on a half-million aeronautical chart?
Controlled airspace up to flight level 195 and its classification
What does the following mean on a half million aeronautical chart?
LEEDS BRADFORD CTR D
SFC-FL85
Leeds bradford control zone, class D, from surface to flight level 85 (8,500ft)
What controlled airspace can be seen on a quarter million aeronautical chart?
All controlled airspace with a base at or below 3,000ft amsl
What does SVFR stand for?
Special VFR
Can SVFR be flown in a control zone?
Yes subject to clearance from ATC the following conditions apply:
-remain clear of cloud and keep surface in sight
-the in flight visibility must be 1500m or 800 for helicopters
-speed must be below 140kts
-daytime only
Ground visibility of 1500m or 800 for helicopters
-cloud ceiling not less that 600ft
Can you get SVFR clearance at night in the UK?
NO
How should a basic PPL holder cross the airway?
Cross at a right angle of an en route section of an airway where the lower limit is a flight level. Must be VMC
i.e. if the lower limit is FL75 the pilot may cross below this
Are you permitted to penetrate an airway?
Only if you have a valid instrument rating, in a VMC flight and you are following a flight plan.
And you have ATC clearance
What is class G airspace?
Uncontrolled airspace
What is open FIR?
Uncontrolled airspace
What air traffic services do you have in open FIR?
Flight Information Service (FIS)
Radar services
In ATZs and MATZs discrete communication frequencies are estaablished for the responsible aerodrome authorities
What radio services are available in open FIR?
Traffic or deconfliction service provided by Air Traffic Service units
What are the dimensions of a Air Traffic Zone? (ATZ)
From ground level to 2000ft aal (above aerodrome level)
2nm radius circle for a runway of 1,850 or less OR
2.5nm where the longest runway is greater
What does the pilot in command need to do to fly in an ATZ
Have permission from ATC
OR
The pilot has suffucient information from the aerodrome flight information service or air ground radio to fly safely
When an ATZ is in a class or airspace with more stringent rules, which rules must be followed?
The more stringent ones (strickter)
What is the MATZs dimensions
From the surface to 3000ft above aerodrome level with a radius of 5nm
With a sub or stubs with a width of 4nm extending a further 5nm between 1000 and 3000 ft of aerodrome level
Can pilots of civil aircraft penetrate MATZs?
It is advised you dont but you can. However the MATZ has an ATZ inside of it that must be observed at all times.
What is a class A airspace?
Busiest airspace, all of which is unavailable to VFR flights
What is class C airspace?
Above FL195 where IFR and VFR are permitted. Reserved airspace does exist where VFR flight is subject to specific arrangements with ATC
What is Class D airspace?
Less busy controlled airspace. Above 6000ft amsl including the ATZ in class D VFR in classes C and D require flight notification and ATC clearance
What is class E airspace?
Controlled airspace at and below 6000ft amsl. You do not require notification or ATC clearance. You also recieve less information from ATC
What is class F airspace?
Uncontrolled airspace Not allocated in the Uk
What is class G airspace?
All uncontrolled airspace that has not previously been allocated (Open FIR) including ATZ MATZ and Radar Advisory Surveillance areas
What is a prohibited area?
An area where flight is prohibited
What are restricted areas?
Airspace where flight is restricted to certain conditions
What are danger areas?
An area where activities dangerous to flight may occur
What is a solid red danger area?
A danger area active in published hours
What is a pecked red danger area?
Inactive danger areas unless notified by NOTAM
If a danger area has a black star what does this mean?
The danger area is subject to bilaws so must not be entered during period of activity
If and obstruction is 300 feet agl, what does this mean?
300 feet above ground level
How high might a glider carry the winch used for take off?
2000 ft agl but this can be exceeded in some places
What is a DZ?
A parachute dropping zone
What is an AIAA?
Area of Intense Aerial Flight
Try to avoid these if possible but if you enter one then be extremely vigilant
What level does military low flying take place?
2000 ft agl, with the greatest concentration being at 250-500 ft agl
What is a GVS?
A Gas Venting Site. Light aircraft pilots are advised not to fly over these as they create severe turbulance
How high should you be if travelling over a bird sanctuary?
At least 1500 feet agl
What is a HIRTA?
High Intensity Radio Transmissions Area
