Hi

 

A manual says "A wind of 062 degrees with 11 knots results in a headwind component of 2 knots. So enter 0/HD2 into LS2R etc ..."

 

1. How to get the 2 knots?

2. Is OAT that should be inserted on FMS/FMGC/FMC the one we can get from ATIS?

3. Is it correct that 062/11 means wind direction is 62 and the speed is 11 knots?

 

Thanks

1) You have to figure the headwind component. I have a few rough formulas I use on the fly in real life, but >>this<< calculator seems to be more accurate. Enter the runway heading, wind direction, and speed in knots for that calculator.

2) I assume you're referring to the takeoff data entry page for OAT, regardless of the add-on. I typically just use the temp given on the EICAS screen, but ATIS will be the same. Yes. (I'm not touching de-rating...)

3) Yes, that example would be correct. For future reference, ATIS/Tower gives wind in magnetic heading. METARs and Winds Aloft data are given in true heading.

Go here http://www.aero.sors.fr/adacalc.html and download the adacalc calculator. it does "everything!"

Zach, Okay I get it now, thanks. I dunno if it affects much in fs9 thou.

both sims feature crosswind component. But, they don't give the pilot the instinctive feel apparent in real life.
