Regarding the conversion angle, I realised my mistake shortly after posting but forgot to change it.

The velocity question is fine also, I simply forgot to convert the new GS to IAS! I have the answer as 20kts with no problems now.

With the INS question, I have drawn a diagram with lines 30W and 10W converging to the N Pole and line 20W straight and a horizontal 60N line. I then drew in a concave line (towards the pole) to represent the rhumb line, then noted wether there should be an increase or decrease by judging the angles. Is that correct?

I have also noted another question where I can not match my answer to the 'correct' one.

An aeroplane is flying at TAS 108kt on a track of 090 degrees.The w/v is 045/50kt.How far can the aeroplane fly out from its base and return in one hour?

a) 56nm
b) 88
c) 85
d) 176

Using the CRP5 I get

GS Out 148
GS Home 218/219

60 x 219 148
----------- = 35.8 ------- = 2.47 = 2.47 x 35.8 = 88.426nm
148+219 60

According to the answer I have, it should be 85nm. Any idea where I may be going wrong?

Cheers
