As an aside to this discussion, a few months ago after putting the landing gear handle down we received the ECAM,
L/G GEAR NOT DOWNLOCKED. To say the least, that got my attention. At my carrier we have a special procedure regarding this ECAM where we are to cycle the gear handle up to five times in an attempt to get the gear down. On the third try the gear came down.
Maintenance replaced the gear safety valve among a few other things.
