while maintaining good EGT and CHT Differential Limits, fly with the CGR-30P and note the maximum
spread for both EGTs and CHTs for all stages of flight. Set the EGT and CHT “Hottest to Coldest Differ-
ence” field to 35’F above the maximum spread.

EGT/CHT Scan Rate – This field sets the rate at which the digital EGT and CHT readout (at the bottom
of the bar graph display) will scan from one cylinder to the next, when in the Scan Mode.

6.4 USB and Data Recording Screen:

Note: This screen is not accessible during engine operation.

This screen allows you to download flight data to the USB Data Stick
and set the Data Sample Rate. The Data Sample Rate is the time interval
between recorded data. The CGR-30P can record up to 1500 flights
before it records over the oldest flight first. The USB port may be found
mounted in the instrument panel or hanging under it.

Flight data is recorded and downloaded in a comma delimited format.
This allows the file to be ported directly into Excel. The file names are
formatted as follows (see Appendix A2.0 for more information):

Flt0001_20130123P.csv

Flt0001 - This is Flight Number 1.
_2013

- This is the Year.

- This is the Month (January)

- This is the Day (23

)

- P = Instrument was only powered-up, E = The instrument was powered-up and the

engine was running, F = The aircraft was flown (the flight timer started).

The current Flight Number is shown at the bottom of the screen. This number increments each time the CGR-30P
is powered-up.

6.5 Fuel Alarm and Unit Info Screen:

This screen provides the following features:

Recurring Fuel Alarm – A recurring fuel alarm may be set to
alert the pilot each time a set amount of fuel is consumed. For
example; if the aircraft has 40 gallons of fuel on-board and the
alarm was set for 10 gallons, when the fuel remaining dropped to
30 gallons you would get an alarm. Also, the alarm will recur at
20, 10 and 0 gallons. The word “SWITCH” between the RPM
and M.P. gauges will blink in white when the Recurring Fuel
Alarm is activated. The alarm is intended to help the pilot
manage fuel by reminding him/her to switch fuel tanks. The alarm
