1.2 out of 5
Battery drain

I have anxiety when I have to check my schedule on ARINCFOS. Anytime you check it, ARINCFOS completely updates, which takes anywhere from 2 to 6 minutes as the phone warms up. There is no quick check without a complete re-sync of all data. Incredibly slow, cumbersome and painful to use.

WHY!😡

I’ve tried for months to make the switch. I REALLY REALLY TRIED. Our fleet has experienced so much pushback by our pilots, most have abandoned it for using the old version until it disappears. Old FOS was great. It looked cohesive and orderly.

Fine. You need to make adjustments. Why is new FOS such a completely reworked app? It is so totally different it’s hard to look at. And that’s the best part...
1) Everything is centered (hard on the eyes)
2) There are 2 lines for a 1 leg trip. (Takes longer to figure out what we are looking at. It all looks the same!!!)
3) can’t delete a receipt entered on the wrong line. (We have to bother accounting to do so)
4) going from leg details back to the main schedule screen, it “JUMPS” and you lose track of where you were.
5) given a trip to a 4 letter identifier, old FOS would have the name and place of the location. New FOS doesn’t that I can find.
6) for no apparent reason, some of my tail numbers have multiplied on the schedule.

I legitimately can’t think of ANYTHING that is an improvement for a pilot. It’s like a CPA or engineer with ZERO input from the field wanted to start from scratch. Listen to the crowd and adjust the product!

Behind the times...

"I would not recommend using FOS Mobile in airplane mode with a wifi connection."....FOS tech support. Really? Whoever said it should be called DOS was being nice.

Worst app ever

ARINCFOS constantly sends me the message “Issue while syncing FOS calendar the request timed out”. It’s so bad that I can’t get my work done and if it was up to me our company would cut ties with Airinc all together because of this program.

Almost useless

Fails to sync on three of four attempts. Even when it does sync, it fails to download all trip data. Used to be reliable, but for about three months now, has been a nightmare.

Not Ready for Prime Time!

I agree with the other reviewers that old FOS Mobile was much more intuitive and had far fewer issues. If Rockwell Collins hadn’t stopped supporting it, I would immediately uninstall the new version and replace it with the older one. I just can’t understand why Rockwell Collins felt compelled to completely rework a useful app just to add some “eye candy.” Adding my voice to everyone else’s: Bring Back Old FOS!

Needs to fix bugs

Erases times randomly when inputted so you have to input times multiple times. When you submit it says submitted then goes to logged and replaced times with other numbers not inputted. You have to submit your times multiple times before they finally show submitted. Even then it will give you block time errors or replace your inputted information.

Slow

Sync takes forever and drains battery, something as simple as a schedule shouldn’t take this long to load. I also get Sync errors almost every time I open ARINCFOS .

Horrible

ARINCFOS has gone so far downhill in the last few weeks/months I hope that our company just switches to anything else soon. Works maybe 1% of the time if you have hours to keep trying to refresh everything and even then good luck trying to get all the information you need. Youd think maybe they would try to fix anything but it has only gotten worse more recently.

Improve the app

One of the worst apps on planet earth!

Terrible app

Horrible app. never works.

😵‍💫😵‍💫😵‍💫

Please upgrade this hunk of junk to include a background refresh feature!

Why

People live in space but I can’t see my calendar unless I let it load for 30 minutes. Do better

Terrible app

Works 10% of the times and when it does it takes several minutes to update… terribly useless for pilots

If you like Productivity, You’ll Hate this App

Sync, storage, updates, and interface are necessary but when it comes to this waste of space. You're better off finding another vendor.

App needs to be fixed

The old app was much better

Logging out 4 times per day

Seriously, FOS has the capability to doing some amazing things BUT its usefulness is exceeded by its design flaws. Why am required to resubmit reports multiple times? Why am I required to log in (up to 4 times in a 24 hour period) to check my schedule? In recent weeks, I have spent more time troubleshooting; deleting and reinstalling ARINCFOS, attempting to make sure I am running the most current version and logging back in and making corrections, than I do any other function. When I have to renter my credentials multiple times in a day just to log in and check my schedule, the program then fails to become a resource and becomes more or less an unreliable “annoyance.”

Makes my PeePee sad

Honestly, refresh times in app take awhile, every few months you have to uninstall and reinstall ARINCFOS so it doesn’t take 10 minutes to refresh.

Better...

It’s improved since the update, but it’s still sluggish at times when saving pre & post flight data.

Great App

Rockwell Collins has gone to great lengths to continuously improve ARINCFOS. The latest version allows all crew on a trip see the submitted pre-flight and post-flight information. For those that don’t like the calendar view, I recommend adjusting your filters to see only the information you want. Having access to documents from my phone or iPad is invaluable.
My only complaint and the reason I only gave ARINCFOS four stars was the non-functional airport database. PLEASE FIX THIS!!!
Would like to see an interface to Crew Alert.
