Ralf,

I use Seattle Avionics Voyager and fltpln.com. Voyager is a big program and is best used on a fast machine with decent sized memory. The preflight planning is a snap. It optimizes for altitudes after downloading weather.

I use fltpln.com primarily for recently accepted IFR routes.

Good luck,

Craig Gainza

Subject: [LML] finding the right altitude in a 4P

Dear subscribers,
 
One question bothers me for a while now and maybe someone can give me an
answer on it.
 
How do I find the right altitude with a head wind?
 
Usually winds get stronger when you go higher - at the same time the
plane goes faster when you go higher. 
 
If I think long enough I probably could come up with a solution
calculating headwind components at different altitudes and comparing it
with the 3 kts speed increase per 100ft (Craig Berland's number).
 
How do you find your altitude without messing around for too long?
 
Thanks
 
Ralf
