Vis 5km
1500m horizontally
1000ft from cloud
What are the rules of IFR separation?
1000ft above highest obstacle with 5nm
Describe class A airspace
Controlled airspace
Below FL195
Describe class C airspace
Controlled airspace
FIRs above FL195
UIR above FL245 and FL660
Describe class D airspace
Controlled airspace
Additional protection for aerodromes
Some airways below FL195
Describe class G airspace
All uk airspace that’s not controlled
What are the 3 categories of Flips?
Planning documents (pre-flight)
En-route documents (during flight)
Terminal documents (arrival at destination)
What is the range of FIRs?
Surface to FL245
What is the range of UIRs?
FL245 - FL660
Who controls London FIR/UIR?
Swannick - London ATCC
Who controls Scottish FIR/UIR?
Prestwick - Scottish ATCC
What is the definition of controlled airspace?
Airspace of defined dimensions with a control service provided to IFR flights
What is civilian Air traffic know as?
GAT - General Air Traffic
What is military air traffic know as?
OAT - operational air traffic
What is a control Zone (CTZ)?
Controlled airspace around an aerodrome extending from the surface to a defined upper limit
What are control areas (CTA)?
Controlled airspace above a control zone.
It has a defined lower altitude and a defined upper altitude.
The upper altitude can be unlimited but it’s usually FL245
What is a terminal control area (TCA)?
The combination of a Control Zone, Control area and airways.
What are the dimensions of a MATZ?
5nm radius from runway
Stubs extending a further 5nm by 4nm long
Between 1000ft and 3000ft
What is temporarily reserved airspace and why do we use it?
Allows military to fly VFR between FL195 - FL245
Operational during specific times
What are restricted areas?
Defined dimensions where flight of aircraft is restricted
What are prohibited areas?
Defined dimensions where flight of aircraft is prohibited (e.g: nuclear stations, royal residence…)
What are provost marshal areas?
Defined areas where flight of military aircraft is prohibited or restricted
Known as PMP/PMR
What are danger areas?
Defined dimensions where activities dangerous to the flight of aircraft occur
What is purple airspace / CAS-T?
Temporarily controlled airspace
IFR is compulsory
Provides protection to Royal flights
What are the types of AT service available?
Radar control (controlled airspace)
```
Outside controlled airspace
Basic service
Traffic service
Deconfliction service
Procedural service
~~~
Describe radar control
Mandatory
Details of conflicting traffic
Must not change level or heading without approval
ATC responsible for collision avoidance
Describe basic service
General information and weather
Describe traffic service
Basic service plus….
Provides position on other aircraft but not headings for you to turn on..
ATC not required to separate you
Pilot is responsible for collision avoidance
Describe deconfliction service
Basic and traffic + …..
Provide ADVISE on deconfliction on how to avoid other aircraft
Collision avoidance is pilots responsibility
Only provided to aircraft operating at or above ATC units terrain safe level
Describe procedural service
Basic service + …..
Pass advice/deconfliction on other aircraft on procedural service
Cannot pass info on aircraft not on the procedural service
What is the lateral separation minima (horizontal)?
Normally 5nm
Reduced separation Can be 3nm in specific conditions
What is the vertical separation minima?
Inside CAS 5000ft
Outside CAS 3000ft
If I’m heading westerly, what type of FL will I be on?
Even, starting at 2000ft (IFR)
VFR is even + 500ft E.G: 2500ft
If I’m heading easterly, what type of FL will I be on?
Odd starting from 3000ft
2000ft intervals
VFR is odd + 500ft e.g: 3500ft
What is the importance of 3000ft at cranwell?
This is the transition altitude where you would set 1013hpa when climbing through it
What is the transition level?
The point, when descending, where you would change from SPS to QFE
The transition level changes
Name the types of ATC services
Radar control
(controlled airspace, ATC responsibility for deconfliction)
Basic (general info and weather)
Traffic (basic + levels and headings, pilots responsibility for separation)
Deconfliction (advice on deconfliction, collision avoidance pilots responsibility)
Procedural (no radar, only deconflict you from other traffic on a procedural service)
What does pmr stand for
Provost Marshall restriction
What colour are taxiway lights?
Blue
What are the colours of ident beacon for mil and civ
Civ - green
Mil - red
