Try going around the other (shortest) way.
340 + 20 gives you 360/000 then you have to add 100 to get to 100 degrees.
For what its worth, you can use Sin(240)x30 and the answer is -26 knots. If you remove the minus sign you end up with the same answer anyway.

The angluar distance between 340 deg and 100 deg is 120 degrees.
If you still can't see it, look at the compass rose on the wind side your CRP-5 (or equivalent) and count the 10-degree divisions between the two directions.

I was wondering if anyone could help me with these 3 questions from comms exam that came up this week?
IFR Comms
Q. Isolated CBs have been forecasted along a route. An aircraft flying in a layer of nimbostratus sees a lightning flash. What actions should the pilot take?
a) Declare a PAN as he has flown into a storm.
b) Transmit an AIREP because the CB is embedded. <<<<<<<
c) Report the Lightning at the next waypoint, which is only 15 mins away.
d) Nothing, because the CBs have been forecast.
Q. For which of the following transmissions should each number be spoken individually?
a) Climb to 2500 feet
b) Visbility 4000 metres
c) QNH 1000 <<<<<<<<<<<<
d) Overcast 1300 feet
Q. Aircraft may be required by ATC to make airborne reports of air temperature, wind and turbulence. Aircraft not equipped with data link equipment are:
a) Exempt to make regular reports, unless specifically requested by ATC <<<<<<<<<<<<
b) Required only to report once, immediately after being requested
c) Are required to make regular reports, irregardless of position.
d) Are only required to make reports upon passing reporting points, not more than 30 mins every time.

A note on the first question, NS is associated with warm fronts and stable air and its very rare to get embedded CB in NS, although it can unusually happen when the warm sector is very unstable (unusual) and initial frontal lifting sets them off. One would have hoped the forecasters would have picked this up and included the possibility of CBs embedded in the NS, but apparently not and only ISOL CB were forecast not ISOL EMBD CB, and therefore the answer selected is correct.

I was torn between B and D in all honesty! Since the CB has already been forecast, if it was in a practical flying sense then you would have aircraft continuously calling up along the route/Airway, reporting the CB/Lightning!!

In case anyone is interested, in answer 2, this is straight from CAP 413:
2.13 When transmitting messages containing aircraft callsigns, altimeter
settings, flight levels (with the exception of FL100, 200, 300 etc.
which are expressed as ‘Flight Level (number) HUN DRED’),
headings, wind speeds/directions, pressure settings, airspeed,
transponder codes and frequencies, each digit shall be transmitted
separately;

Bryan Johnson told me way back when that the ICAO document is the only one that follows a national document, in this case CAP 413...... Put another way, 413 is edited first. Go figure.

Question bank vs OAA CBT
Hello,
For the ATPL theory, are question banks (like Bristol Ground School) a more valuable tool than Oxford's CBT? I was looking over some Human Performance questions and the banks don't get into as much detail as the CBT. For example, the questions touch the surfaces of Dalton's Law, yet the CBT seems to be too in-depth.
Thanks,

Think the best solution is to use them both!
Personally i use Aviation exam instead of bristol but I also use the CBT to get some deeper understanding, Question banks is ideal to know what you are supposed to focus on! gl! =)

Why can the following METAR not be abbreviated to CAVOK?
DLLO 121550Z 31018G30KT 9999 FEW060TCU BKN070 14/08 Q1016 TEMPO 4000 TS=
(Aerodrome elevation 1000 ft, MSA for sector 000-190° 5800 ft, for sector 190-360° 7300 ft.)
Accord to QB correct answer is:
Because the cloud base is below the highest minimum sector altitude.
I'm a bit lost with this one. As far as I understand you don't add the elevation to MSA as MSA is 'altitude' above sea level? If you do add the elevation then I understand how they get this answer.
Practically speaking, if the MSA is 5800ft MSL then I don't think I'd fly 200ft below TCU, so it is common sense at that.

The term 'cloud base' in the answer given as the correct one is slightly misleading as the definition of CAVOK does not refer to any cloud base. However, the conditions for CAVOK are not met since (1.) there are clouds below 1 500 metres (5 000 ft) or below the highest minimum sector altitude, whichever is greater, and (2.) there is towering cumulus.

I guess the examiner was thinking along the same lines as Negan.
I got this from the BGS bank, but I didn't take note of the question ID.

ICAO Annex 3 says:
2.2 Use of CAVOK
When the following conditions occur simultaneously at the time of observation:
a) visibility, 10 km or more;
Note.— In local routine and special reports, visibility refers to the value(s) to be reported in accordance with 4.2.4.2 and 4.2.4.3; in METAR and SPECI, visibility refers to the value(s) to be reported in accordance with 4.2.4.4.
b) no cloud below 1 500 m (5 000 ft) or below the highest minimum sector altitude, whichever is greater, and no cumulonimbus;
c) no weather of significance to aviation as given in 4.4.2.3 and 4.4.2.4;
...and our interpretation is that TCu is not CB

And purely for reference, but here is the extract from EASA consolidated SERA, effective October 2017:
SERA.9010 Automatic Terminal Information Service (ATIS)
(b) ATIS for arriving and departing aircraft
...
(13) visibility and, when applicable, RVR (*) and, if visibility/RVR sensors related specifically to the sections of runway(s) in use are available and the information is required by operators, the indication of the runway and the section of the runway to which the information refers;
(14) cloud below 1 500 m (5 000 ft) or below the highest minimum sector altitude, whichever is greater; cumulonimbus; if the sky is obscured, vertical visibility when available; (*)
...
(*) These elements are replaced by the term ‘CAVOK’ when the following conditions occur simultaneously at the time of observation: a) visibility, 10 km or more, and the lowest visibility not reported; b) no cloud of operational significance; and c) no weather of significance to aviation.
And from the same document:
‘cloud of operational significance’ means a cloud with the height of cloud base below 1 500 m (5 000 ft) or below the highest minimum sector altitude, whichever is greater, or a cumulonimbus cloud or a towering cumulus cloud at any height.
The term 'weather of significance to aviation' I could not find a definition for within SERA, and wonder how this differs from the previous term. I believe that ICAO Annex 3 defines both terms.
Clear as mud
