I don't sink YT videos are copyrighted, right?

Have a look here: EGPWSAnyway: EGPWS Mode 3 is active from liftoff until a safe altitude is reached. This mode warns for failure tocontinue to gain altitude. The original Mode 3, still specified in DO-161A as Mode 3A, produced warningsfor any negative sinkrate after take-off until 700 ft of ground clearance was reached. The mode has sincebeen redesigned (designated 3B in DO-161A) to allow short-term sink after take-off but detect a trendto a lack of climb situation. The voice callout for Mode 3 is “Don’t Sink.”

There are 7 videos on YT explaining how the EGPWS modes work. I'll post the link to the first video below:EGPWS: Mode 1 - Excessive Decent Rate You can access the other videos via the "Suggestions" column.
