What does it look like when it's locked? Can't access at all?

Theres a note at the top saying your application has been locked for review; some items can be edited but others cannot. That’s it.

When filling out applications, theres a section on incidents. Are companies looking for any kind of incidents or just incidents due to pilot error/fault? I have incidents like aircraft mechanical problems in flight that requires non normal procedures (e.g engine troubles). Do I report this on my application as well?

Use the FAA definition of 'incidents'. That's how I read that question anyways...

So once it's locked, do I have to save it when I exit it or what?

Is yours still locked? Mines been locked for a week now, just trying to get an idea what the waiting time to get a Hogan is like now.

Idk about timeline etc but remember to check your spam

Same here. It's a waiting game now

Same here. Locked for 3 weeks now. No further correspondence.

Check my app in the morning and was untouched. Later that day I recieved Hogan invite. I checked app again and it was locked. So to answer your question, it all happened in a matter of hours.
