2.6 Communications Antenna Installation Notes
For best results while in Dual installations or Split Mode (two communicates transceivers active at the same time), we
recommend that the one VHF communications antenna is located on top
of the aircraft while the other communications
antenna is installed on the bottom
. Any antenna relocation must be accomplished in accordance with AC 43.13-2A,
aircraft manufacturers’ recommendations and FAA-approved technical data.
Warning:
It is probable that radio interference will occur in the split mode when the frequencies of the two aircraft radios are
adjacent, and/or the antennas are physically close together. PS Engineering makes no expressed or implied war-
ranties regarding the suitability of the PAC24 in Dual or Split Mode.
2.7 Wireless telecommunications interface
The PAC24 has interface capability with units such as the AirCell Guardian. It is the user’s responsibility to determine
the appropriate legal use of the equipment, and provide the equipment and services.
As installed in the standard configuration, the PAC24 Com 5 function operates conventionally. Pushing the Com 5
Xmt button places the receive audio from Com 5 in the headset and applies the pilot or copilot microphone to the Com
5 when the appropriate PTT is activated.
If telephone mode is selected by the internal DIP switch the PAC24 is forced into Com 5-Duplex mode. This mode is
designed to operate with telecommunications systems, such as the AirCell AGM.01. Intercom Audio streams are pro-
vided to the COM 5 output, the PTT for Com 5 is inactive, and audio from Com 5 is presented to the headset. This
allows a telephone-like audio interface. The COM 5 input and output is compatible with aviation radios.
In a DUAL Audio Panel installation, the telephone mic audio input should be connected to the PILOT COM 5 Mic
output (J3 pin only).
PS Engineering makes no expressed or implied warranty that the equipment will be compatible with any devices
other
than AirCell.
Unauthorized use of cellular telephone devices in aircraft is subject to FCC enforcement action,
which may include a $10,000 fine per incident. PS Engineering, Inc. does not endorse using unap-
proved cellular telephone equipment in flight, and takes no responsibility for the user’s action.
