Comm/Nav Checklist (Charlie) Flashcards
“CLOCK”
Set current time and wind until light tension is felt.
“SET AND WOUND”
“ATTITUDE GYRO”
Pull out knob on front of indicators until gyro cages and set mini aircraft on horizon, if necessary.
“CAGED LEFT/RIGHT”
“BAR ALT”
Set barometric altimeter to 177’.
“SET TO FIELD ELEVATION LEFT/RIGHT”
“HSI/RMI”
Ensure Free/Slave switch is in the SLAVE (forward) position and the needle is aligned with the index mark in the small window. Verify the RMI is within 10 degrees of the corrected wet compass (correction from the compass deviation card applied).
If not in agreement, turn off landing light and searchlight, ECS (Air Conditioning), Pitot Heat, and Defog Blower (L.A.P.D.), and check again. If still off, put slave switch in FREE (aft) position and adjust with clockwise/counterclockwise toggle switch. On the compass slaving panel, observe the small window and check that the white needle is aligned with the white horizontal line. Move the switch from FREE back to SLAVE. Turn L.A.P.D. items back on as required.
“SLAVED AND ALIGNED”
“MARKER BEACON”
Activate the test switch, verify all lights illuminate.
“TEST”
“RAD ALT”
Test radar altimeters as follows: (1) Set bug to 25’. (2) Press TEST button. Needle should rise to 50’ +/-5’ with an OFF flag. (3) Release. As needle drops past DH bug, DH light should illuminate and tone should sound. OFF flag should disappear behind the mask. (4) Push DH button. The warning light and tone should cease. Set bug to zero.

“CHECKED”
“GTN HSI/CDI”
Verify display for:
(1) Ensure navigation source selected is NAV 1 for pilot/copilot.
(2) “Half left” with corresponding ½ scale deflection on HSI/CDI.
(3) “Half up” with corresponding ½ scale deflection up on glideslope.
(4) “TO” Flag with corresponding TO flag on HSI/CDI.
(5) Annunciator Panel Check: Pilot should have 8 lights. Copilot should have 9 lights.
(6) OBS display should correspond to the course set in the pilot’s HSI. Once complete, pilot select NAV 2 and repeat test with CDI.
(7) DTK check 150 displayed.
“FUEL”
Set as follows:
(1) Select “Fuel on Board” and add current fuel load. Press “Enter.”
(2) Select “Fuel Flow” and adjust fuel burn rate, as required. Press “Enter.”
(3) Select “Continue” to navigate to Home Page.

“NAV 1 RMI CHECK”
Push the “Direct To” button and select a waypoint (to which the approximate distance/heading is known). Select “Activate.” Observe that the Green needle moves smartly to the correct course and the distance is indicated on the GTN screen.
“TEST AND SET”
“VHF”
Test as follows:
(1) Select Mixer Switches to receive radio #1 on Audio Control Panel.
(A): Push the #1 selector button in on Audio Control Panel.
(2) Switch Transmit Selector to #1
(A): Upper Audio Panel
(3) Disable Squelch by pushing in the ON/OFF/VOLUME knob and use the background static to adjust the volume.
(4) Verify “SQ” in the com field (top right corner)
(5) Enable squelch by pushing in the ON/OFF/VOLUME knob.
(6) Press in and hold the volume knob for 2 seconds.
(7) Verify “121.5” loads in the com field.
(8) Verify “7700” loads into the transponder. Note: This function may not be available in all aircraft at this time. (9) Touch the STBY Field on the right side of the screen. (10) Tune the STBY frequency to “121.95” using the touchscreen keys.
(11) Check Manual Frequency Adjustment using inner and outer knobs in the lower right corner.
(12) Touch “ENTER” to load frequency in STBY.
(13) Touch the Comm field to make the frequency active. (14) Squeeze cyclic trigger and observe “TX” in Com field.
(15) Tune the VHF STBY frequency as desired.
“TEST AND SET”
“VOR”
Set frequencies for the flight, as required. Won’t receive signal on deck KNDZ.
(1) . Push in center knob to change COM to NAV.
(2) . Touch STBY field and then enter the frequency using touch screen.
(3) . Load desired frequency.
“TUNED AND SET”
“TRANSPONDER”
(1) Touch “Transponder” field and enter outbound code through the touchscreen and press “ENTER”
(2) Touch “MENU” field and select “Flight ID”. Enter your appropriate 8-digit flight callsign ID and touch “ENTER”. Touch the “Back” field in the lower left area of screen. (3) Touch “Mode” field. Touch “ON” and verify “ON” on and flashing “R” for transmitting in XPDR field. Return transponder to STBY by touching “Mode” field and “STANDBY”. Touch ENTER”.
“SET”
“UHF”
Turn off squelch and adjust volume. Switch to manual and verify appropriate function. Check guard frequency set to 243.0. Ensure guard is set active.
“TEST AND SET”
“NAV 2 HSI/CDI”
Ensure both pilot and copilot are selected NAV2. Set 70x into KNS-81 and push “USE.” Push in DME button on audio control panel to listen/verify Morse code. Twist course indicated by double RMI needle. Fine tune until it centers. Check 10° either side causes full deflection of course indicator. Twist in reciprocal course and check that TO-FROM flag swaps. Check DME 1.4 +/- 0.5. Pilot select NAV 1. Execute for CDI.
