Hello Captains,

 

I'm going to start flying from airport A to airport B and then flying back to airport A.

Ok, aircraft is parked, deboarding is completed, engines are off, APU is running, SHUTDOWN checklist is complete.

Now I'm going to prepare my aircraft to fly back to airport A. Should I do both SHUTDOWN and SECURE checklists? I don't want to turn off IRS and APU because I'm going to get some fuel and fly back.

So should I do SHUTDOWN checklist, take some fuel and start Normal Procedures from Preliminary Preflight Procedure position? Have I to realign IRS when going to fly back?

Please give me some info what real pilots do in such "short turns".

 

All best!

Shutdown checklist only, fast align on the IRS. Most airports want the APU shutdown asap so use the GPU if available during transit.

 

Regards

Most guys (and most airlines) would do a full IRS alignment procedure. Really, I dont think it is physically possible to turn a half full 737 fast enough so that you can not wait out IRS. Definitely not when you are taking fuel.

 

To do a full IRS alignment, just turn the dials off as you shut down, wait a moment for lights to go out, and turn them back to NAV - and you can go about putting the position in the CDU and continue with preflight.

Peter / Fabo ? is right, you do want to realign and you won't really save time by not doing it anyway.

 

Do it the way my previous poster Fabo described it, that's how the pilots do it as well, noticed every time I flew in the flight deck. They also do full re-alignment, no fast alignment. (Info may differ from other company SOPs).

I would just enter my back trip flight plan without shutting down IRS. Guess I was going something wrong...

Don't know how you guys do it in the states but as long as you are gps equipped and residual ground speed is less then 5kts then a fast align is all that's needed.

 

Different story with no gps or updating from ground based navaids on the inbound trip.

 

Anyways, no harm either way, do what your SOP's tell you.

 

Regards

I usually go with fast align but as mentioned you have more than enough time for a full align with the time it would take to fuel up and board passengers and go through flows.
