When a pilot wishes to transmit for test purposes he requests a "radio check", or asks "How do you read?"
The response to his request will be in number format and will have the associated meaning.

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

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.

As the aircraft is not in actual IMC, there is no requirement for one of the crew to hold a valid instrument rating.

METAR: EGNT 280850Z 21010KT 9999 FEW040 08/04 Q0991

EGNT – ICAO airport designator code
280850Z – Date and time of METAR - 28th at 0850 Zulu
21010KT– Wind direction and speed – 030 at 7kt
9999 = visibility 10km or more
FEW040 = Few at 4,000ft
08/04 – Temperature and dew point – 8°c, dew point 4°c
Q0991 – QNH – QNH 0991

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)

Abbreviation Meaning:
SKC = Sky clear
FEW = 1 to 2 eighths
SCT = 3 to 4 eighths
BKN = 5 to 7 eighths
OVC = Fully overcast

This question requires a CDMVT calculation to get TRUE HEADING.

Drift is not required to answer this question.

Remember:
Deviation East Compass Least, Variation West Magnetic Best, or use the arrow method.

Step 1:

Step 2:

True Track is not required to answer this question, however this is how it would be calculated:

East and West may referred to as a + or - symbol respectively, (eg. deviation -2 = 2°W)

Remember that D is for deviation, not drift, and True Track is not True Heading.

Windshear & Microbursts
Wind shear can be defined as a sudden change in wind velocity and/or direction over a short distance. These changes in wind speed and direction can create significant turbulence and pose a threat to aircraft.

Virga, Thunderstorms, Fronts, roll cloud and inversions are all signs of possible windshear which is usually associated with: jet streams, mountain waves or inversion layers, frontal surfaces, thunderstorms and convective clouds or microbursts, occurring close to the ground.

Virga refers to precipitation that falls from clouds but evaporates before it reaches the ground. While virga itself does not necessarily indicate the presence of wind shear, it can be a sign of atmospheric instability, which can create conditions conducive to wind shear.

Anabatic winds are winds blowing uphill.
Katabatic winds are winds blowing downhill e.g. behind a mountain range.

When large masses of warm air and cold air meet, they do not mix because of density differences. Instead, they form a front, usually hundreds of miles long.

An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation.

Occluded fronts usually form around mature low pressure areas.

When an aircraft is operating VFR above FL100, it must remain 1,500m horizontally and 1,000ft vertically from cloud in Class G airspace.

I had to rush my checks and did not feel ready, so i decided to release the rope..

Light signals from a ground ATSU differ depending on whether they are to an aircraft on the ground or an aircraft in flight.
