Altitude warning horn question

[rascalsailor]

Hi
What is the purpose of the altitude warning alert? Is this configured for a particular altitude depending on the destination as a general warning?
(saw this on a 737 landing video)
thanks

It warns the crew that the aircraft is passing 1000ft from the level or altitude that the aircraft is set to level off at.

[HAWK21M]

The Altitude alert warning indicates the Aircraft is within 300ft of the selected heading either approaching it by light indication or moving away after crossing it by a light & horn Indication.

Its normally used as a reminder to the crew to act at that particular altitude.

Not a clue what Hawk is talking about, and I fly the things.

In the 60s,70s and 80s it told the crew the aircraft was descending through FL100 above the ground as a safety warning for the "clockwork instrument" Flight Deck but for the life of me I can't remember if it was fitted to the "all glass intrument" Flight Deck perhaps Torque tonight would tell me
