Page 15: Introduction
The Jeppesen database cards provide up-to-date information about airports and other navigation aids around the world. The FreeFlight 2101 I/O Approach Plus GPS System comprises one Dzus-mounted Receiver/Display Unit (RDU) containing a GPS Receiver (12-channel), one GPS Antenna/ Preamp, and applicable installation hardware (see Section 1.4.2 for the appropriate part numbers).
Page 16: Receiver/Display Unit
FreeFlight 2101 I/O Approach Plus GPS Navigation System 1.2.1 Receiver/Display Unit The Receiver/Display Unit (RDU) is the main component of the FreeFlight 2101 I/O Approach Plus navigation system. The RDU consists of the GPS Receiver, the User Interface, and the System Interface. 1.2.1.1 GPS Receiver The GPS Receiver interprets the satellite transmissions to determine the current position.
Page 17: Gps Antenna
The GPS Antenna (P/N 81194) receives and amplifies GPS Signals. The GPS Antenna unit is an omnidirectional flat microstrip antenna with an integral preamplifier and is rated to 1300 knots IAS. An alternate antenna (P/N 16248-11) can be used with the FreeFlight 2101 I/O APPROACH Plus in installations without Satcom. Antenna P/N 81194 is recommended.

SECTION II - Installation GENERAL This section provides general information for installing the FreeFlight 2101 I/O Approach Plus GPS Navigation System. The cables will be fabricated by the installation agency to fit these various requirements. This section contains interconnect diagrams, mounting dimensions and information pertaining to installation.
Page 30: Gps Antenna Installation
The GPS antenna, the antenna gasket (-21kit only) and two 90° TNC connectors are provided in the installation kit. Straight TNC connectors are also available from FreeFlight. Proper antenna installation is critical to both the performance of the system and the aircraft's structural integrity.
Page 31 FreeFlight 2101 I/O Approach Plus GPS Navigation System • Fastening to Fuselage (for 16248-11 antenna) CAUTION Do not tighten screws with more than 20 inch-pounds of torque. Damage to antenna will result and void warranty. Torque value = 18 ±2 inch-pounds.

The FreeFlight 2101 I/O Approach Plus requires no periodic maintenance or calibration. Maintenance is performed on an on-condition basis only. The FreeFlight 2101 I/O Approach Plus is continually tested using Built-In Test Equipment (BITE) when the system is in operation. This method of testing will notify the operator of a failure. System software updates are accomplished using the card slot on the front of the unit and instructions described in normal Service Bulletin notification.

A flashing satellite number indicates a satellite which is being tracked but not being used in the position solution. The GPS annunciator on the FreeFlight 2101 I/O Approach Plus front panel indicates that sufficient satellites are being used to provide position updates.
Page 71 If the number of satellites in use drops to the point that GPS navigation is no longer possible, then too much interference exists between VHF radio and the FreeFlight 2101 I/O Approach Plus. Two common sources of interference are from the VHF radio front panel to the GPS antenna and from the VHF antenna to the GPS antenna.

Page 130: General Description
The FreeFlight 2101 I/O Approach Plus GPS Navigation System will provide position accuracies commensurate with selective availability, provided that the system is receiving adequate satellite signals. The FreeFlight 2101 I/O Approach Plus has demonstrated that it is capable of and has met the accuracy requirements of: VFR/IFR domestic en route, terminal and non-precision instrument approach operation within the U.S.
Page 131: Section Iv - Limitations
NOTE: Many of the waypoints identified in the Jeppesen NavData database and used by the 2101 I/O Approach Plus to fly the approach may be unnamed in the published Terminal Procedures. These included waypoints such as the intersection of two radials, DME positions, waypoints located on a DME Arc, turn waypoints, or waypoints to indicate a Final Approach Fix (FAF).
Page 132 Waco Texas, 76706 with FreeFlight 2101 I/O App Plus GPS The FreeFlight 2101 I/O Approach Plus can only be used for approach guidance if the reference coordinate datum system for the instrument approach is WGS-84 or NAD-83. (The NavData data base used in the FreeFlight 2101 I/O Approach Plus only contains WGS-84 geodetic datum referenced data).

Page 135 HSI Display: Cross track deviation, TO/FROM, and navigation valid flag data from the VOR, ILS or Trimble 2101 I/O Approach Plus can be displayed on the HSI indicator depending on the state of the NAV/GPS. To display left/right cross track deviation, TO/FROM and flag valid information on the HSI indicator from the FreeFlight 2101 I/O, place the navigation selector switch to the GPS position.
Page 136 (FAF to MAP) when sequenced to the FAF, the Trimble 2101 I/O Approach Plus will automatically place the unit in HOLD mode (HLD) at or abeam the FAF and prompt the pilot to enter the outbound course from the FAF.
Page 137 All missed approach procedures should be executed manually. 9. Once a destination airport has been established with an ETA, the FreeFlight 2101 I/O Approach Plus will automatically determine RAIM availability at the destination. The prediction shall cover a time period ±15 minutes from the ETA, in intervals of 5 minutes.

Page 139: Section Vi - Emergency Procedures
RAIM: In enroute and terminal operation, continue to navigate using the Trimble 2101 I/O Approach Plus, or revert to an alternate means of navigation appropriate to the route and phase of flight. When continuing to use GPS navigation, position must be verified every 15 minutes using another IFR approved navigation system.
