2.17.1 TY91 Checkout

2.17.1.1 Ground check:

1. Connect an in-line type watt meter and verify that the antenna VSWR does not exceed 2:1 across

the frequency band from 118.000 to 137.000 MHz.

2. Select the frequency of a local communications facility and verify that the receiver output is clear

and intelligible.

3. Establish communication with a local facility and verify that the transmission is reliable, and

quality is clear and intelligible. Verify that sidetone is present for the appropriate crewmembers

and passengers (depending on intercom mode).

4. If appropriate, verify selection of 8.33 kHz channel selection. Refer to §3.6.1.2

2.17.1.2 Flight check:

1. Maintain at least 1500 feet AGL, and establish reliable contact with a facility at least 25 nm

away.

2. Contact a facility within five nm and verify reliable contact.

3. Open the radio squelch by pushing the right knob for more than 2 seconds (or until the volume

and squelch bars appear), and listen for any unusual electrical noise that might reduce the com-

munications receiver sensitivity.

4. Verify operation at both high and low end of the frequency band (118.000 to 136.975 MHz) if

possible.

2.17.2 TELEPHONE Checkout

On the ground (not flying), activate the TELEPHONE mode using the Bluetooth device. Verify that the

pilot headset is connected to the cellular telephone system (if installed). Verify that by using the pilot side

PTT, the pilot can transmit on the other selected radio (Com 1 or Com 2). The telephone function will

place any person heard by the pilot on the intercom, also heard on the telephone.

2.18 Final Inspection

Verify that the wiring is bundled away from all controls and no part of the installation interferes with air-

craft control operation. Move all controls through their full range while examining the installation to see

that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accor-

dance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the

cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and

that all contact points are protected from abrasion.
