Thanks for your advice guys.
I started on it yesterday taking off from EGGP. I am now in Iran at OIII.
I am just heading in the general direction I think I need to go and using http://www.worldatlas.com/aatlas/world.htm to look up place names then looking for airports in that area.
Im only making fairly short flights as my work timetable doesnt allow me to fly too long flights but here is what I have done so far
EGGP - EDDM
EDDM - LQSA
LQSA - LGIR
LGIR - LCLK
LCLK - OIII
Next step is OIII to OPKC which is in Pakistan. It will be my longest flight so far on my trip. Over 1000nm.
During my last leg the flaps got stuck in position 1 on the approach. Bit of a bumpy landing coming in fast but landed safely and got some nice bonus points too 😀
