BUR-SL-1 Series 7

BUR-SL-1 Series 7 onboard solid-state recorder

BUR-SL-1 Series 7 is an onboard recording unit intended to collect, process and preserve operational and flight information. It supports accident and incident investigation as well as routine monitoring of aircraft operation. The solid-state design eliminates magnetic recording media and allows the unit to record multiple signal types in a programmed configuration. The exact Series 7 execution must be confirmed because other BUR-SL-1 series can differ in interfaces, channel capacity and system integration.

Signals and recording capacity

The recorder accepts analog signals, programmable discrete commands and navigation code signals through an RS-232 interface. It also records service information such as current time, power-on number and aircraft identification number. Recording duration depends on the selected word rate: the stored interval changes as the number of words recorded per second increases. Channel assignment, polling frequencies and the data frame are therefore part of the aircraft-specific configuration and must match the installed system documentation.

Readout and processing of BUR-SL-1 data

Recorded information can be transferred through RS-232 to an IBM-compatible computer or notebook and processed with the Dozor or Topaz-M ground systems identified for this equipment. This allows post-flight review without opening the protected memory section. When acquiring a unit, compatibility must be checked not only by connector appearance but also by software configuration, supported signal formats and the available ground readout equipment.

Aircraft use and protected construction

Documented applications for BUR-SL-1 Series 7 include the Mi-35 helicopter, M-101T Gzhel and Su-38 aircraft. The recorder is designed for use in aviation recording and operational-monitoring systems and is rated for vibration, shock, reduced pressure, humidity and temperature exposure. Its protected construction also specifies resistance to impact, static load, fire, sea water, fuel and extinguishing fluids. These characteristics describe survivability; they do not replace the installation approval for a particular aircraft.

Identification and related recording equipment

The requested unit should be specified as BUR-SL-1 Series 7, with the series, connector arrangement, software configuration and documentation confirmed before supply. Related catalogue positions include BUR-LKV-01 and RZBN-1, shown for navigation rather than interchangeability. The complete section is available in the flight recorders and tape devices category. General background on the purpose and operation of this equipment class is available in the flight recorder reference article.
