Who sets your Altitude Alert?

I am doing a poll. What is your company SOP regarding who sets the Altitude Alert? Does it change whether somebody is handflying or using the autopilot? And personal opinion: How do you think it should be done and why?

Thanks!

I've stopped flying now but it was simple:

Hand flying - set by PNF

Autopilot flying - PF

Simples

Really?

Who does the speed/heading bugs or selects V/S etc?

Hand Flying - PNF
Autopilot - PF

Pilot not setting the altitude must point at the new set altitude and say it.

On Autopilot - PF
Hand flying - PNF

Like Zoner says, considered a "required cross-check" item, so whoever is setting it actually speaks to the other pilot who acknowledges what is being set.

Same here..

Hand Flying - PNF

AP on - PF

Who ever does it, sets the altitude and reads it and confirms it with the other guy.

A/P engaged:

PF - selects FL/altitude and says it.
PNF - acknowledges when correct FL/altitude is selected.

Handflying:

PNF - selects FL/altitude and says it.
PF - acknowledges when correct FL/altitude is selected.

At all times:

PNF calls "1000' to go" prior to level off at selected FL/Altitude and PF acknowledges. Usually the aural warning gets in the way.

On the 737 Classic the altitude alerter sounds at 900 feet to go to the selected MCP altitude. On many occasions the PNF's wait until the alerter sounds and then belatedly sing out "Thousand to Go." A bit bloody late, Mate.

Have even heard a PNF call "thousand to go" when the chime sounded because the aircraft had left a level for a new level but the crew forgot to select the new level in the MCP and the chime sounded when the aircraft had climbed 300 ft above or descended below current MCP altitude. Monkey see - monkey do, comes to mind...

In the simulator, if the instructor quietly disables the altitude alerter to check the alertness of the crew (without telling them first) invariably the PNF forgets to call "thousand to go" and the PF forgets too. Which means neither are monitoring the altimeters. Observed this slack attitude on countless occasions which means crews rely blindly on the alerter sound to remind them of the approaching altitude rather than have the situational awareness to closely monitor climb or descent rates to selected altitudes

Yes the aural warning is suppose to be a reminder/back up rather than the driver as the crew set the FL/Altitude themselves and are suppose to be flying the aircraft! Too much reliance on that little chime me thinks
