b) The tachometer must exceed the TachHi setting, and then go below the TachLo entry. This will
generate an tachometer warning (the red warning light will flash, the page will change to the labeled
page that includes tachometer, and the tachometer will flash).
Acknowledging this alarm (by pressing the "Ack" button") results in the following:
c) After the warning has been acknowledged, the function is reset, requiring the Hi setting to be again
exceeded before the alarm is generated again.
d) The warning light will go out when the landing checklist reminder warning is acknowledged.
The recommended setting for AspdLo and TachLo is a setting that is below what you normally
encounter in takeoff, climb, cruise, and descent, but above what you encounter when entering the
pattern, or while in the pattern. (If you set the "Lo" threshold too low, you may not get the warning
until you have already landed, if too high, you may get it long before you are planning on landing.)
The recommended setting for AspdHi and TachHi is a setting that is above what you normally
encounter while in the pattern, but reasonably below what you would encounter in takeoff, climb,
cruise, or descent. (If you set the Hi threshold too high, you may not ever go above it, preventing a
landing checklist warning from being generated, and if you set it too low, you may get the alarm
repeated due to power/airspeed changes made while in the pattern.)
You may find some trial and error is necessary to fine tune your settings so your reminder is generated
reliably, and not more than once.
An example of the use of this function may best illustrate how to us it. I have found from experience,
that based on my flying habits, my RPM does not go below 1900 until I am in beginning my descent in
the pattern for landing. I have also noted that while in the pattern, even when making large power
changes, my RPM does not go above 2400, although it always goes above 2400 during takeoff. I set
my TachLo entry to 1900, and my TachHi entry to 2400. With my flying habits I consistently get an
RPM warning (landing checklist reminder really), when I enter the pattern.
Caution : At power-up of the instrument, the checklist function is reset. This means if the instrument
is turned off and on again while in-flight, and you do not exceed the "Hi" threshold again, you will not
get the warning. Also remember that if something unusual happens (such as partial power loss, staying
in the pattern, etc.) , you may not go above your "Hi" threshold, and thus will not get a landing
checklist reminder
. Do not rely solely on the landing checklist reminder function to perform your
pre-landing checklist.
7.12.2 RPM Range Limit
This function is available in software version 5.0 and above, only.
The TachHi, and TachLo settings are also used to specify an RPM range for which an alarm will be
generated. When used in this manner, these entries will not function as a checklist reminder.
To use the TachHi and TachLo entries as an RPM range alarm, the TachHi setting must be a lower
value than the TachLo setting.
When the EIS detects that you have set them in this way, these entries
define the RPM range within which it will generate an RPM alarm. For example, if you wish an alarm
when the RPM falls between 2000 and 2250 RPM, set TachHi to 2000, and TachLo to 2250.
