General

The Ameri-King AK-451 series is a FAA and EASA approved 406MHz ELT type AF/AP/S. It transmits aircraft GPS/NAV position data on triple frequencies: 406MHz (satellite), 243MHz (military SAR) and 121.5 (civilian SAR).

The AK-451 can be used both in fixed installations as well as in mobile/handheld applications. Suitable antennas are delivered with the unit or available as accessories. Installation is simple. A mounting tray, remote control panel and complete cable harness are provided with the unit.

The Lithium battery pack delivers up to 78hrs of transmit operation at the end of its 5 years service life. The AK-451 interfaces with the aircraft GPS/NAV system via RS-232 serial line. Protocols of all major suppliers such as GARMIN, Honeywell Bendix King, Trimble, Arnav and II Morrow are supported.

The unit comprises a reliable, sealed G switch for crash detection. A 5 axes G switch for helicopters use is available as an option. The initial progamming is included in the sales price.

GPS Navigation System with very high accuracy built in Pressure Transducer, SD card interface, Approach Mode, Flight Recorder, GSM Modem Interface and with option of built in Flarm warning system.

General

The LX 707 is derived from the proven LX 500 system that is fitted to the fleet of Grob 115Es (Tutors) operated by the Royal Air Force as well as from the LX 7007 glider flight management system. It offers in an all-in-one package a practical point to point navigation system with a database of airfields and airspace built in but, compared to the LX 500, the LX 707 has the important addition for the General Aviation community of a high accuracy pressure transducer (as used in glider flight recorders) that enables the LX 707 to provide an airfield approach capability with both localiser and glide path information, albeit without certification, without the need for a differential GPS ground station. The addition of this separate height sensor, which can be set to QNH or QFE, moves the on-board GPS from a simple navigation assistant to one that can have real benefit for the final approach to a waypoint or airfield after the input of runway data.

Features

• 80 mm diameter
• 85mm long 125 mm total length including connectors
• Weight approx 550 g
• Power requirement: 10 – 28VDC, approx 200mA

Options include

• Remote stick top control
• Additional 57 mm display units (for system expansion)
• Second seat unit
• Voice warning module
• Interface with LX electronic compass
• GSM modem interface (enables on-line monitoring of the aircraft`s position)
• Integral Flarm collision avoidance system with built-in graphic display

The Database

The airport and airspace database is free and the updates are available from www.lxnavigation.si. (LX navigation publishes updates three times each year as a minimum.) The airspace data is in the well known .cub format and this has the advantage of allowing pilots to use third party sources of airspace. SeeYou .cub files may also be loaded. In addition, LX Navigation offers a free program called LXAs browser which enables many other airspace data formats to be converted into .cub. It also enables the user to modify existing .cub files. The LX 707 has sufficient memory capacity to store up to six .cub files and this would cover virtually the whole of Europe. A file may be recalled at any time and during flight.

The waypoint database allows for 600 points to be entered and also for 100 routes to be pre-programmed. (the data format is .da4) Data transfer can be executed by use of SD card or PC.

SD Card Interface

The SD card enables a wide range of data to be easily transferred. The SD card slot is positioned on the right hand side of the unit and will accept a micro sized SD card. (An adapter to enable the SD card to be inserted into a PC is included)

A pilot`s name and preferred settings for the LX 707 can be stored on an SD card thus allowing the pilot to program the instrument to his requirements by inserting his SD card before flight.

In Flight – navigation and approach

The primary function of the LX 707 is to provide navigation information towards an airport or waypoint following a pre-programmed route; each of these modes is supported by sub pages which display the required information. The basic menu functions in Airport mode, for example, can be controlled via this page:

For example, navigation information to a selected airport or waypoint can be displayed like this:

Or when getting close to an airport, this time Celje in Slovenia, the display can be like this:

and the route map can be displayed like this:

The clever feature is that the LX 707 has a precision altitude sensor built in which has adjustment in flight for QFE/QNH etc and this is coupled to the equally high quality GPS receiver such as to enable a precision approach procedure to be flown after the input of runway threshold data and the glide slope required. ( Please note that this not an EASA or otherwise certified system.)

This facility can be further extended by the addition of the LX Compass Module that enables all key navigation information to be displayed on the same screen.

Flarm Option

Flarm collision avoidance system may be implemented as an option. LX 707 with Flarm option offers a very usable graphic traffic information display, which gives easily understood information about nearby Flarm equipped traffic traffic.
The integrated Flarm option uses the LX 707 GPS receiver that is used for navigation and no additional GPS antenna is required.

Flight Recorder Option

In addition to the electronic log book which comes as standard, a flight recorder option may be ordered. An IGC compatible file, albeit without secure data, may be downloaded to the SD card.

GSM Modem Interface Option

A plug and play connection to a LX GSM modem makes it possible to both monitor the aircraft in real time on-line and also to undertake flight analysis after flight. The LX Navigation server is capable of playing back the last part of the flight at any time. The log book is also available under request. All the customer has to do is to log to the LX Navigation server and input his personal password and user name to get access.
This map below shows the track (in yellow) and current position (in red) of an aircraft using a LX 707 and the GSM Modem Interface Option.

Using the GSM Modem feature may improve safety as the last aircraft position is always known and available on internet.
