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

Q

Can you get SVFR clearance at night in the UK?

A

NO

22
Q

How should a basic PPL holder cross the airway?

A

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

23
Q

Are you permitted to penetrate an airway?

A

Only if you have a valid instrument rating, in a VMC flight and you are following a flight plan.
And you have ATC clearance

24
Q

What is class G airspace?

A

Uncontrolled airspace

25
Q

What is open FIR?

A

Uncontrolled airspace

26
Q

What air traffic services do you have in open FIR?

A

Flight Information Service (FIS)
Radar services

In ATZs and MATZs discrete communication frequencies are estaablished for the responsible aerodrome authorities

27
Q

What radio services are available in open FIR?

A

Traffic or deconfliction service provided by Air Traffic Service units

28
Q

What are the dimensions of a Air Traffic Zone? (ATZ)

A

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

29
Q

What does the pilot in command need to do to fly in an ATZ

A

Have permission from ATC
OR
The pilot has suffucient information from the aerodrome flight information service or air ground radio to fly safely

30
Q

When an ATZ is in a class or airspace with more stringent rules, which rules must be followed?

A

The more stringent ones (strickter)

31
Q

What is the MATZs dimensions

A

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

32
Q

Can pilots of civil aircraft penetrate MATZs?

A

It is advised you dont but you can. However the MATZ has an ATZ inside of it that must be observed at all times.

33
Q

What is a class A airspace?

A

Busiest airspace, all of which is unavailable to VFR flights

34
Q

What is class C airspace?

A

Above FL195 where IFR and VFR are permitted. Reserved airspace does exist where VFR flight is subject to specific arrangements with ATC

35
Q

What is Class D airspace?

A
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
36
Q

What is class E airspace?

A

Controlled airspace at and below 6000ft amsl. You do not require notification or ATC clearance. You also recieve less information from ATC

37
Q

What is class F airspace?

A

Uncontrolled airspace Not allocated in the Uk

38
Q

What is class G airspace?

A

All uncontrolled airspace that has not previously been allocated (Open FIR) including ATZ MATZ and Radar Advisory Surveillance areas

39
Q

What is a prohibited area?

A

An area where flight is prohibited

40
Q

What are restricted areas?

A

Airspace where flight is restricted to certain conditions

41
Q

What are danger areas?

A

An area where activities dangerous to flight may occur

42
Q

What is a solid red danger area?

A

A danger area active in published hours

43
Q

What is a pecked red danger area?

A

Inactive danger areas unless notified by NOTAM

44
Q

If a danger area has a black star what does this mean?

A

The danger area is subject to bilaws so must not be entered during period of activity

45
Q

If and obstruction is 300 feet agl, what does this mean?

A

300 feet above ground level

46
Q

How high might a glider carry the winch used for take off?

A

2000 ft agl but this can be exceeded in some places

47
Q

What is a DZ?

A

A parachute dropping zone

48
Q

What is an AIAA?

A

Area of Intense Aerial Flight

Try to avoid these if possible but if you enter one then be extremely vigilant

49
Q

What level does military low flying take place?

A

2000 ft agl, with the greatest concentration being at 250-500 ft agl

50
Q

What is a GVS?

A

A Gas Venting Site. Light aircraft pilots are advised not to fly over these as they create severe turbulance
