Flap Overspeed Alert Tweak - Minor Add to 9.3

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I see some message traffic in various forums about R9 guys wishing there was a way to reduce the frequency of "Flap Overspeed" aural alerting.
We're going to make a two-part tweak to this in the hopes of addressing some of those concerns.

1.  We will provide a means for the pilot/user to turn off the flap overspeed aural alert if they so choose in the SYS-Display Setup tab as part of 9.3.   If you really don't like ever hearing the alert, then use this on/off selection to deselect it.

2.  We will add about a 4 sec time delay in the next release of DFC100 so that the overspeed condition (e.g. > 119KIAS with flaps deployed in a Cirrus) must be true for a minimum of 4 seconds.  That is intended to minimize the scenario where you've got flaps deployed right near 119 KIAS in gusty/turbulent conditions and have momentary exceedances of a few knots or a few seconds.

As a side note, I do personally find the flap overspeed aural alert helpful in one particular scenario.   Due to decaying personal skill sets, I find myself forgetting to raise the flaps during climbout at an ever increasing frequency.  I like this crutch.
