Cockpit Horn

[poolep 0]

I'm on decent.  Flaps 5, Flaps 10.... N1 about 50%...gear up.

 

Speed decreases......Flaps 15.  So far so good.  I capture the glideslope and reduce N1 to below 45% - a horn sounds.

 

The only way to stop it is to lower the gear or increase N1 to more than 46%.

 

Is there a way to cancel the horn ?  I've tried the small black button on the overhead panel "Alt Horn Cutout" and the black button on the Throttle Quadrant "Horn Cutout" without success.

 

Is there a way to stop this horn ?

Flaps 15 through 25 -

Either throttle set below approximately 20 degrees or an engine not running, and the other throttle less than 34 degrees; the landing gear warning horn cannot be silenced with the landing gear warning HORN CUTOUT Switch.

Yeah - stay at 10 or gear down...

Hi ??????.

 

This is the landing aural warning to tell the flight crew the landing gear is not down and locked. When the airplane is between 200 and 800 feet AGL (radio altimeter) with the flaps between 0 and 10 units and thrust levers are set for landing. This aural warning will operate, to cancel this push the Horn cutout switch next to flap lever.

 

When the airplane decents lower than 200 feet AGL the landing warning Horn will operate again. The only way cancel this is to lower the landing gear. The Horn cutout switch will not silence the aural warning, because at this altitude the airplane should be set landing.

 

When flaps are from 15 to 25 units with gear not down and locked and thrust levers are set for landing. The landing aural warning Horn will operate, the only to silence this aural warning is to lower the landing gear. When the flaps are set lower than 10 units the airplane should be set for landing.
