Please have a look at my BOD chart which is straight out of the VFRG
I have done the method the correct way
please see that my lines of latitude between 35 and 30 where sydney intersects 18th of August shows me 1804 as opposed to 1809
My chart is not from the AIP but a valid publication for the exam
If I use 1804, then it comes to 2000 UTC and not 2005 which is the AIP answer

Can anyone help in this regards

Also I logged onto NAIPS and used the coordinates for Sydney, and sure enough the BOD was 2005.
Anyone have any suggestions. In the real world I would use NAIPS , phone for the answer but for the exam any suggestions?
Should I just download the relevent sections from AIP?

Kind regards

Ravi

Just to humour me, could you post the original question, please ?

apologies it was asking for the BOD 18 August Sydney with latitute of 33S ( the exact coordinates )

there were 4 answers all in UTC raning from 2000, 2005, 2010 I cant recall the last

Technique looks OK. Do watch out for inadvertent typos along the way which can cause confusion under any sort of pressure.

thank you so much
