Falling value triggers alert

Recommended Posts

Hi all,I'm trying to add the decision height callouts to my panel but I don't know how to trigger a one time only event.For example I want the event to be triggered when the radio altimeter reached the dh altitude but not to keep triggering if the plane stayed at that height.Any ideas?Thanks,

Paul,Not tested, but you could try:(A:Radio Height,feet) (A: Decision Height,feet) - 20 < (A:Radio Height,feet) (A: Decision Height,feet) - -20 > (A:Flaps Handle index,enum) 5 > (G:Var1) 0 == && && && if{ 12345678 (K:ADF Complete Set) 1 (>G:Var1) } (A:Radio Height,feet) (A: Decision Height,feet) - -20 > (A:Radio Height,feet) (A: Decision Height,feet) - 20 < && if{ 0 (>G:Var1) }So this means the callout can be heard only once ( (G:Var1) 0 == )when difference between Dec. and Radio Height = 40 feetand in landing configuration (flaps handle index);The condition (G:Var1) 0 == becomes immediately (G:Var1) 1 ==so the sound cannot be triggered anymore.After that (G:Var1) becomes automatically 0 ==.Assuming not taking off with full flaps, you will not hear the sound.Btw. of course you have to use xml-sound.gau of D. Dawson to generate the sound.Hope it helps,Jan"Beatus Ille Procul Negoiis"

Hi,Vertical speed = negative could maybee also be used as a condition for callouts, to avoid to trigger it when you climb if you have several landing confs for flaps which could be used for take off as well.BrgdsEugen
