Regarding the post above...check out this guy's "homepage" listed on his profile...then I think you'll agree whatever he has to say is a total 12 yr old wannabe but know it all opinion...
BTW, when was the last time any of you real pilots let the FE decide on and sign off the fuel load and flight plan???...IOMAP does it all the time according to info found on his profile....what a waste of time and bandwith...
