A320 Secondary Flight Plan

[EIU_EEC]

Hi. Turn Around time is short. So decide to prepare Secondary Flpln for next leg.
Question is will all the details in SEC Fpln be deleted along with primary 30 secs after landing in Done Phase?? When to activate secondary flpn after landing to lower the workload.

[nitpicker330]

Gee mate why don't you just try leaving it in after shutdown and see what happens!!

1/ if its still there then activate

2/ if its not then take 2 mins and start again, it doesn't take long to load an Airbus FM.

3/ NIKE

It will remain...

[Field In Sight]

It definitely remains.

I use it for the same purpose. Don't forget, you can also setup as much of the performance as you already know for the next leg.

[truckflyer]

I will remain, but why don't you store it in the memory, you can still use Sec Flpn for other useful preparation that might be required!

[Slasher]

It'll remain till you activate it for the next sector. You can store it as previous
suggested so as to use the SEC FLT PLN but dunno why - there's nothing you
can't do already on the PRI PLN or do an insert on the RAD NAV if ATC decide
to suddenly change yer runway. The missed appch can still be done raw data
like we used to do in real aeroplanes.

Only exception is bloody China (specifically Beijing) where there are a dozen
STARS for each of the 3 runways and ATC never tell you to use the same one
you used yesterday. Best to put the most likeliest other STAR in the SEC PLN
in case, as its not till your on App freq that the buggers will advise the STAR.

The SEC FLT PLN though is very handy for enroute use such as redispatch and
PNR (incl PNR EO) calculation. If you want to set up the next sector do so on
receipt of the wx about 1 hr prior to arr so as to determine RNY and perf figs.

[EIU_EEC]

For PNR do you use the ETP function or insert time markers on secondary flpln page from the CFP? Coz etp n pnr will be different.
And suppose you hav to send the etp toc reports via acars do you insert them as time markers as default etp is between dept n dest...but you need to change them for strategic planning

[Slasher]

.....You can calculate ETP EO then PNR EO on the SEC PLN by entering Mach,
levels and wind then use the SIAS method. Shouldn't take more than 5 mins
each if your initial guesstimation isn't far off the mark. You can then enter a
time marker for each on the PRI PLN and/or annotate 'em on your CFP.

The ETP thingy on the 320 box is AEO.

[EIU_EEC]

hi,slasher. I am not familiar with the SIAS method. Can you please brief me, and the detail as to how to use the Secondary flight plan page to create PNR Engine out and CP. thank you.

[nitpicker330]

What you can't work it out???

Same in any FMC.

Copy the active.
Modify the sec to another destination from a Lat revision much further down the track after where you estimate the PNR should be.
Link up Airways/Waypoints back to the PNR Airport including the RWY and STAR arrival.

Check planned FL's, entered winds etc.

Look at the Arrival fuel at the PNR, it's up to you how much fuel you would like to arrive at the PNR with. I'd suggest a minimum of 30 mins but consider this does not yet take into account a Depress cruise.

If too much fuel then move the PNR further out
If not enough then bring it back a bit.

This isn't too hard and works ok.

Remember to "fine tune" all the inputs into the box as much as you can for a more accurate answer of FOB at the PNR.

[Slasher]

SIAS = Suck It And See...... a la nitpicker's para -

If too much fuel then move the PNR further out
If not enough then bring it back a bit.

Rest you can figure out yerself. It isn't hard as nitpick said.

If having a return leg flight is required you could consider storing a flight plan using the stored flight plan function (DATA page 2).

If you have sufficient time in the cruise or on the ground on the first leg you can use the init function of the secondary plan and build up the bones of the return leg.

You can insert the take off runway, the SID, the STAR and the landing runway. Every other item altn, flt number, cost index, flight level, isa dev, & winds are flight plan elements that cannot be retained and although you can enter those values it will advise you that they are not saved so don't bother.

Then go to DATA page 2 stored flt plans. If on the ground you have 2 prompts store primary and store secondary; in flight only the store secondary feature is available.

Select one of these prompts and a blank name prompt appears at MCDU 1L.

Enter a unique name for the plan (example your first name). Then line select save secondary.

So when you set up the next flt you go to the primary flight plan and insert your depart/ arrival ICAO identifiers, and in addition to any of the company routes that are stored you will see as you page right your stored plan.

You can store 3 of these plans, you can use the secondary flight plan and you can can continue the primary plan route to the alternate. This gives 5 possible alternates to use.

To delete the stored routes after landing when the MCDU reverts to the status page select 5R on the MCDU and removes the evidence

Hope this helps.

Just as a matter of interest: If you do all the above on the way there, surely you have nothing to do during the quick turn?

[andreminella]

How short is this Turn Around? It doesn`t take more than five minutes to insert all data, mainly when your company has co-routes.
But, you can save your flight plan and still use the SEC FPLAN for an alternate arrival at your actual destination.
