As stated the IMC course does not tackle these points i asked about,just planning and more planning.The written was close to my VFR nav test i feel alot is missing from the IMC course work.In the defence of my instructor he has asked me to come in for a chat to go through the points i asked on here,he can only teach what is on the course i guess.Anyway thanks for the replys GOOD information as usual!Cheers !
