We believe this question, which was submitted with ambiguous language is asking you to identify the fact that in class D airspace separation is not the responsibility of ATC between VFR and IFR Aircraft, (only traffic information is provided, not separation) it does not indicate which aircraft would be responsible, we would go with VFR.

Class D.
IFR and VFR flights are permitted and all flights are provided with air traffic control service, IFR flights are separated from other IFR flights and receive traffic information in respect of VFR flights, VFR flights receive traffic information in respect of all other flights.

Land at this aerodrome. DAY or NIGHT — Lowering landing gear, (if fitted), showing steady landing lights and following the intercepting aircraft and, if, after overflying the runway in use or helicopter landing area, landing is considered safe, proceeding to land.

The International Standard Atmosphere (ISA) states that temperature decreases at approximately 2°C (1.98°C) every 1,000ft and that temperature is 15°C at sea level.

Solution:
Find the ISA temperature at 3,000ft

2 (°C per 1000ft) x 3 (thousand feet) = 6°C

Therefore it is 6°C colder at 3,000ft than at 0ft

15°C (ISA Sea Level Temp) + 2 (Reported ISA Deviation) = 17°C

17°C – 6°C = 11°C

Stratiform clouds are associated with a warm front. The cloud types also suggest an ever lowering cloud base.

1° = 60 nautical miles
1' = 1 nautical mile

25° 00' - 15° 30' = 9° 30' 

The aircraft has travelled 9°30'

9° x 60 = 540nm
30' = 30nm
540nm + 30nm = 570nm

(or 9DMS 30DMS x 60 = 570nm)

Remember:
QNH = Altitude above sea level
QFE = Height above ground

Solution:
Elevation of airfield is 270ft AMSL and QNH is 1019.
What is the QFE?

The pressure drop at 270ft is:
270 ÷ 30 = 9hPa (30ft = 1hPA)

1019hPa – 9hPa = 1010hPa QFE

Your senses may be deceiving you, you may feel you are in a bank, climb or descent, should you encounter disorientation, you should use and trust your instruments.

The feeling of breathlessness at altitude is caused by a reduction in air pressure. The composition of the air remains roughly the same.

The gas composition of air is:
Oxygen 21%
Nitrogen 78%
Noble gases 1% (argon 0.9% / carbon dioxide 0.037%)

The mass of a 1m cube of air at MSL is 1,225kg.
Water may be found in the atmosphere in liquid, solid or gaseous states.

If air pressure drops and altitude remains the same then the altimeter will over-read.
i.e. it will show a figure higher than true altitude and the aircraft will be lower than expected.

Air pressure drops by approximately 1hPa per 30 feet increase in altitude.

Solution: High to low down you go!

The aircraft is flying from a pressure setting of 1025 QNH to 1016 QNH

1025 hPa – 1016 hPa = 9hPa
9 hPa x 30 = 270 ft

So the aircrafts true altitude is
4500ft – 270ft = 4230ft

Airfield B is 450ft above sea level

so the height of the aircraft is:
4230ft – 450ft = 3780ft

The elevation of Aerodrome A is not relevant.

Aerodrome Traffic Zones surround many UK aerodromes to protect aircraft around the airfield from passing flights.

An aircraft may not fly within an active ATZ unless the pilot in command has the permission of the ATC unit (if applicable), or contacted any other type of Air Traffic Service Unit. The radius of the ATZ depends on the length of the longest runway at the aerodrome.

Clouds are usually divided into 3 levels according to the part of the atmosphere they are found.

High clouds (CH) Base usually 20,000 ft or above
Cirrus, Cirrocumulus, Cirrostratus

Medium clouds (CM) Base usually between 6,500 and 20,000 ft.
Altocumulus, Altostratus, Nimbostratus

Low clouds (CL) Base usually below 6,500 ft over British Isles.
Stratocumulus, Stratus, Cumulus, Cumulonimbus

Cloud names are usually combinations of the following prefixes or suffixes:

Stratus/strato: flat/layered and smooth
Alto: Medium level
Cumulus/cumulo: heaped up/puffy, like cauliflower
Cirrus/cirro: High up/wispy
Nimbus/Nimbo: meaning ‘Rain-bearing’

Vertical development of Cumulus clouds into rain showers is called "over-development."

When using the QNH pressure setting, vertical position should be expressed as altitude.
When using the QFE pressure setting, the vertical displacement above the airfield is communicated as height.
When using standard pressure setting 1013.25hpa vertical position is communicated in flight levels.

The coldest time of day is said to be just after sunrise.

This is because during the night the earth is continuously losing heat energy.

It does this until the sun reaches a point in the sky where the Suns radiation exceeds the heat radiation lost from night cooling.

Sea breezes are caused by the diurnal temperature cycle and the difference in temperature changes between land and sea.
