Q

What are the dimensions of an ATZ?

A 
2nm radius (or 2.5nm if the runway length > 1850m)
Surface to 2000ft AAL (ABOVE AERODROME LEVEL)

Note - Therefore have to add on aerodrome elevation to your altitude if aiming to overfly whilst QNH/RPS is set

Surface to 3000ft AAL

Stubs = 5nm long, 4nm wide (2nm either side of centreline)
1000ft to 3000ft AAL (1000ft gap underneath allows the stubs to be flown under)

Q

What are the three designations of Airspace Reservation?

A

Prohibited
Danger
Restricted

17
Q

What are the three statuses afforded to Airspace Reservations?

A

Permanent
Scheduled
Notified (NOTAMs)

18
Q

Where can details on airspace reservation be found?

A

UK AIP and UK LFHB
Where restrictions are only applicable to military users (e.g. Provost Marshal’s Areas), details are published in the UK MilAIP.

19
Q

What are the rules regarding prohibited areas?

A

No aircraft are permitted inside prohibited areas; only those specifically permitted to enter for operational reasons are exempt.

20
Q

What are the rules regarding restricted areas?

A

Flights are subject to restrictions; where aircraft need to enter to perform authorised duty it must do so in compliance with ATC procedures.

21
Q

What are Provost Marshal’s Areas?

A

Areas of prohibited (PMP Areas) or restricted (PMR) airspace defined by the RAF Provost Marshal.

Only applicable to military aircraft.

Details in UK MilAIP.

22
Q

What do all aircraft need to fly in a Danger Area (DA)?

A

Authorisation

23
Q

What is DACS?

A

Danger Area Crossing Service - A nominated ATC can give clearance to cross but will not provide separation from other traffic

24
Q

What is DAAIS?

A

Danger Area Activity Information Service.

Provides info on the activity going on in the DA but it’s the pilots choice whether to enter/cross.

25
Q

What are HIRTAs, how are they marked on charts and where can further details be found?

A

High Intensity Radio Transmission Areas

Marked on a map as a purple looking star surrounded by a purple circle.

Comms, weapons, navigation systems, etc may be affected in these areas.

Details in UK AIP and UK LFHB (Low Flying Handbook).

26
Q

How are Areas to Avoid marked on charts?

A

Red diamond surrounded by a red circle.

27
Q

What are MTAs?

A

Military Training Areas

28
Q

What are AAIAs, ATAs and AARAs? Where can details be found?

A

Areas of Intense Aerial Activity
Aerial Tactics Areas
Air-to-Air Refuelling Areas

Details found in the UK Civ AIP.

Best to avoid, but if you are unable to do so it is advisable to make use of an ATC radar service.

29
Q

What are TRAs?

A

Temporary Reserved Areas

Airspace that is normally under the authority of one aviation authority (i.e. CAA) and by agreement is temporarily reserved for use by another aviation authority (i.e. MAA).

Established between FL195 and FL245 in the UK.
