Hi Folks,

thanks for your input, has proven very helpful so far There's one thing to shed some light on left though:
I calculate my TOD and leave it at idle thrust (LVL CHG). Now, as far as I know, during descent the "spare mileage" will increase as the flight path angle at high speeds is quite neat (i.e. i'm at FL250 and have 80NM to go... 25x3= 75... 80-75=5 miles spare....later on I'm at FL120 and have 43NM to go...12x3= 36...43-36=7 miles spare). How do you include that effect in your calculations? Adding 5 or 10NMs at TOD doesn't really work ou then, does it? In my opinion i want to have about 10NMs "spare" reaching FL110 to have 10NMs spare for speed reduction.... but how do i figure out whether or not I am in slot at FL250 or FL300???

It's not rocket science..i know....I'm just curious

regards
