Can you enter any flight info in the FMC after takeoff?

[lineman55]

I had taken off last night just to work on some procedures..with no flight plan entered...and once I was up at 12000' I wanted to enter an arrival at a nearby airport..and it wouldn't let me.Is this normal in the real world? or do you have to enter all info prior to push back? I couldn't enter anything..fuel weight..nothing.It seems to me a quirk or something...appreciate any info you might have.

Hello

When im doing some tests I often do a takeoff without any ORIGIN or destination aiport.

You can enter a destination airport at RTE page. When you have done that you can select a arrival.

To get the correct approach speeds you also need to enter your ZFW at the PERF page. You should be able to do that in the air also.

Ok I did go directly to the Dep/Arr page and it wouldn't take any input. I did go to the page for ZFW also and couldn't do anything there thinking this must be step 1 to make other pages available. 

So route first and then that opens available info pages...thankyou

Are you doing it like this ?

You need to know your ZFW before you takeoff, since you cant access the ground service menu in air.

if you choose PREFERENCES in the pop out window on left in the cockpit...that was my only source for ZFW to work from while already in flight.I can get it before the flight no problem and input no problem..just while in the air after I take off .. wouldnt these numbers work as well?
