PMDG 747-400X FMC Question

Recommended Posts

In the FMC, the Hold button I am assuming allows you to enter a holding pattern (could not find documentation in the manual). I am assuming you downselect the fix to LSK 6L. A few questions:- What is the PPOS> in LSK 6R ? How does it work ?- Is there an option on the type of holding pattern (std right hand turns or can it manage non-standard left turns ?)- Is there an option on holding pattern duration (1 minute, 2 minutes ?)- How's the holding pattern terminated ? Clear LSK 6L ?Thanks,Zach

Your assumption, Zach, is correct. Once you have established that, all your other questions can be answered using the information in the page that shows up at that time.Jean-Guy

Hallo Zach,Some answers to you Holding questions:>In the FMC, the Hold button I am assuming allows you to enter>a holding pattern (could not find documentation in the>manual). I am assuming you downselect the fix to LSK 6L.Correct. The HOLD page will then suggest a holding pattern, Right turns, 1 or 1.5 mins leg, on the inbound course to that fix according the LEGS page. (this may be different from a published pattern as discribed in nav documents. Can be adapted, read on)>- What is the PPOS> in LSK 6R ? How does it work ?When selecting PPOS a standard hold pattern is created at present position.>- Is there an option on the type of holding pattern (std right>hand turns or can it manage non-standard left turns ?)>- Is there an option on holding pattern duration (1 minute, 2>minutes ?)Any holding pattern you select is a suggestion untill it is EXECuted.On LSK 3L you can overwrite INBD CRS/ - TURN as required.On LSK 4L or 5L you can overwrite / enter inbound LEG TIME or DIST as required.>- How's the holding pattern terminated ? Clear LSK 6L ?When in the holding, select HOLD page, then LSK 6R EXIT HOLD. EXIT ARMED will be shown here until overhead the fix again, whereafter the hold is cleared and aircraft continues on the next leg.If you planned a hold ahead, and are not yet in that holding pattern,then select LEGS page and DELETE LSK next to HOLD AT Fixname to clear the holding pattern. (all finally followed by the EXEC of course)Hope it clearifies your questions.Happy Holding, but keep an eye on the fuel remaining!Regards,Harry
