Hey Mutt,
Thank you for your prompt response!
Well, let me start then... Since I mostly fly VFR and prefer old-school navigation to autopilots and GPS, one of the confusing things about the ground prep routine is... TAS! I know what it is in theory - that it depends on pressure, temp, and winds; that it can be roughly derived from IAS by adding 2% to it per each 1,000ft, etc. But how can I know and use TAS before the actual flight, i.e. during the ground prep?!?
I would also like to know about the winds aloft considerations. Particularly, WHY winds are always given for altitudes of 3K, 6K, and 9K ft? And HOW to consider winds during ground prep if say I want to fly at an altitudes in-between these values (eg, 4500 ft, 7500 ft)? Shall I do rough interpolations?
That's all for now! Thank you very much in advance!!!
