After the installation is complete, perform the following required flight checks to ensure satisfactory

transceiver performance.

Check the communications transceiver at a range of at least 50 nautical miles: (This check verifies unit

receiver sensitivity test and transmitter range)

1. Maintain an altitude of 5000 ft AGL.

2. Select the frequency of a ground station facility at a range of at least 50 nautical miles.

3. Verify that communication (RX and TX) can be established with that facility.

Check the communications receiver by receiving transmission from a ground station in close proximity

(range of less than 10 nautical miles): (This check verifies that the receiver has a high signal to noise ratio

when receiving a strong signal.)

1. Select the frequency of a ground station facility at a range of less than 10 nautical miles.

2. Make sure the received audio from that station is clear (no background electrical noise).

3. If possible, perform the preceding steps 1 and 2 for frequencies in the high (~136.XXX MHz), mid

(~127.XXX MHz), and low (~118.XXX MHz) range of the GTR 200.
