take off alternate is required
* A takeoff alternate is required when weather reported (METAR) at departure is below landing minimums at departure airport.
in narmal case may we need to landing after takeoff so if the takeoff metar minima is oky so we don't have problem exept the a/c wieght
and the max landing wieht able for the a/c type
but if we have aready metar at origin a/c is below landing minima
in this case we need to file takeoff alternate to be use if we need it
but we must check for the wieghts of landing case in long range case may be we will need drop feel first to be able to landing with the maxlanding waight
i hope that my word is useful for you
thank's
