You really don’t know much about what’s involved in the production of Nav Databases for use in commercial aviation, do you?
The ‘production’ of them’? NO
But I’ve got a long-time friend who’s a senior commercial pilot. Says his iPad has databases and info on it he’s never heard of, or used. I know he says it’s got data on it for airfields he could never get into, so I wouldn’t be surprised if there was an abandoned airfield database in there.
I’ll ask him the next time I see him.
