Do Pilots need to obtain a forecast for a VFR flight over water? If so, what type of forecast would you require?
Area Forecast (ARFOR).

Yes.
For a destination aerodrome TAF to be acceptable or valid for a particular flight, what period must it cover?
30 minutes before and 60 minutes after ETA.
How would 8 OKTA of cloud be indicated in an ARFOR?
OVC.
What does the abbreviation SKC mean in a forecast?
Clear Sky.
What abbreviations are used in Area Forecast and in forecasts of en route conditions for well-separated Cumulonimbus Clouds?
OCNL CB = Occasional Cumulonimbus.
Is it true that Area Forecasts for operations below FL200 are issued routinely for all Area Forecast areas?
Yes.
What does AMD mean in a forecast?
Forecast has been amended.
Are the cloud heights in an ARFOR given as height AAL or AMSL?
AMSL.
Is wind direction in an ARFOR forecast as Degrees True or Degrees Magnetic?
Degrees True.
In a low-level ARFOR, temperatures are prefixed by letters to indicate whether the temperature is negative or positive. What are the prefixes?
- PS = Positive.
- MS = Negative.
What is a TAF?
Terminal/Aerodrome Forecast.
What is the normal issue period of an Aerodrome Forecast for a Category B aerodrome?
Every 6 hours.
Are the cloud heights in a TAF given as height AAL or AMSL?
AAL.
When you see the numbers 9999 in a TAF, what does this tell you about the visibility?
Greater than 10km.
In a TAF, what does the code 00000KT mean?
Calm Winds.

True.
In a METAR, are the MET conditions forecast or actual values?
Actual Value.
If cloud, visibility or wind is significantly different to that forecast, what sort of report should be submitted by a VFR Pilot?
Short AIREP.
What are routine aerodrome meteorological reports called, how is the data collected and when are they issued (3)?
- METAR.
- MET observes and AWS.
- Every 30mins to 1hr.
Which of the following forecasts, reports and broadcasts give wind direction in degrees true and degrees magnetic – TAF, ATIS Broadcasts, METARs and Takeoff and Landing Reports?
- Degrees T = TAF and METARs.
- Degrees M = ATIS and Takeoff and Landing Reports.
