1

What is an ATS?

Air traffic service

A generic term meaning variously;

  1. Air Traffic Control Service
  2. Air Traffic Advisory Service
  3. Flight Information Service
  4. Alerting Service

2

What is an Approach Control Service?

Where an ATC service is provided for controlled flights associated with arrival or departure

3

To whom do we provide an ATC service?

  • To all IFR in Class A, B, C, D, and E airspace
  • To all VFR flights in Class B, C and D airspace
  • All SVFR flights
  • All aerodrome traffic at controlled aerodromes.

4

What is a Flight Information Service?

A service provided for the purpose of giving advice and information useful to the safe and efficient conduct of flights.

5

To whom do we provide a FIS?

to all aircraft which are likely to be affected by the information and which are:

– Provided with an ATC service, or

– Otherwise known to relevant Air Traffic Services units.

FIS does not relieve the pilot-in-command of an aircraft of any responsibilities and the pilot-incommand has to make the final decision regarding any suggested alteration of flight plan

6

What is an Air Traffic Advisory Service?

-A service provided within advisory airspace to ensure separation, in so far as practicable, between aircraft operating on IFR flight plans.

 

7

What is advisory airspace?

An airspace of defined dimensions, or designated route, within which air traffic advisory service is available.

8

What is an advisory route?

A designated route along which air traffic advisory service is available.

9

Do controllers providing an ATAS have to coordinate?

Yes, excatly like controllers providing an ATC service.

10

What do IFR aircraft need before entering advisory airspace?

A FPL 

11

What must an IFR flight do if crossing an advisory route?

Must cross at an angle that is 90° to the direction of the route.

12

What pertinent information is included in the provision of a FIS?

  • SIGMET and AIRMET information
  • Information concerning Pre-eruption volcanic activity, volcanic eruption and ash clouds
  • Information concerning the release into the atmosphere of radioactive materials or toxic chemicals
  • Information on changes in serviceability of Nav Aids
  • Information on changes in condition of aerodromes and associated facilities, including information on the state of the aerodrome movements areas when they are affected by snow, ice or significant deth of water
  • Information on unmanned free balloons
  • Any other information likely to affect safety

It shall also include

  • Weather conditions reported or forecast at dep. aerodrome, destination aerodrome and alternate aerodrome
  • Collision hazards to a/c operating in airspace classes C-G.

13

Where is Class C airspace found in the UK?

Everywhere above FL195

14

Describe class A airspace

IFR only

Clearance required

ATC must be complied with

Everyone separated from everyone

 

Gliders may enter in VMC

15

Describe Class C airspace

VFR & IFR

Clearance required to enter

Instructions must be followed

IFR sep from IFR & VFR

VFR sep from IFR, given Tx info on other VFR

VMC

16

Describe Class D airspace

VFR and IFR

Clearance required to enter

Instructions must be followed

IFR sep from IFR and SVFR, given tx info on VFR

VFR given tx info on everyone

SVFR treated as IFR for all intents and purposes

VMC

17

Describe Class E airspace

VFR and IFR

IFR require clearance to enter, VFR does not

IFR sep from IFR, tx info on VFR-  avoidance advice given if requested

Participating VFR given Tx info on IFR and other VFR

IFR must comply with instructions

VFR pilots strongly encouraged to contact ATC and comply

VMC

18

What are Class E+ routes?

Same rules as for Class E airspace with the additional caveat that all aircraft must be equipped with transponders.

19

Describe Class G airspace

ATCU's provide FIS, deconfliction advice may be provided

Pilots responsible for all collision avoidance

Pilots still expected to comply with advice

20

What class of airspace takes precedence when two different types join vertically

The lower class

This is to allow them to fly at that level without entering the CAS and comprising the safety of aircraft inside the CAS.

(a class G aircraft could fly as close to base of Class D as he wants so to ensure safety of those in Class D the boundary is treated as Class G and the A/C in class D would be kept away from it.)

21

Describe the vertical profile of the FIRS in the UK

FIR- from the surface to FL245

UIR- FL245 to FL660

22

What is an ATZ and describe its dimensions?

A volume of airspace established around an aerodrome for the proctection of aerodrome traffic.

 

From surface to 2000ft Above aerodrome level (height), centred on the midpoint of the longest runway.

If longest runway is 1850m or less than radius is 2nm otherwise its 2.5nm

23

Do civil ATZ's still exist outside the notified hours of operation?

No

24

What class of Airspace are ATZ's?

They adopt the same class as the airspace in which they sit.

25

What is a MATZ?

A military aerodrome traffic zone

 

26

What is the speed limit in the UK?

250kt IAS below FL100, except;

  • Flights in Class A & B airspace
  • IFR in Class C
  • VFR in Class C airspace if authorised by ATCU and MATS 2
  • Exempted flights in Class D airspace if authorised by ATCU and MATS 2
  • Test flights (specified conditions)
  • Flying displays when authorised by the CAA
  • A/C with CAA written permission
  • State A/C (military)

27

Is the ATZ inside a MATZ active 24hrs a day?

Yes

28

What is TRA(G)?

Temporary Reserved Area Gliders

29

What is RA(T)?

Temporary Restricted Airspace

30

What is a TDA?

Temporary Danger Area
