<p>A typical trainer aircraft carries close to 5-10 training sorties each day. After each flight a turnaround inspection has to be carried out and also in case certain exceedances/ observations are given by flight crew, the same needs to be analyzed manually in detail using the aircraft SSFDR(Solid State Flight Data Recorder) data (e.g. data recorded by the black box). This leads to significant delays in turnaround of the aircraft and also during manual analysis of the data, key exceedances / anomalies are missed or misinterpreted. The data download also requires the aircraft to be powered ON externally or using aircraft battery so that SSFDR system is powered up and data download can be carried out. This also offers challenge in terms of accessing the cockpit by the ground crew for powering up of aircraft, requirement of ground trolley, junction module, AC mains, etc. All this can be eliminated with a single system which is capable of externally powering ON the SSFDR system, downloading the data and analyzing the same in a single step in order to determine the GO/NO-GO for next sortie of the aircraft. If the event of an incident on the aircraft following which it is not possible to power ON the aircraft, this system can be used to power ON the unit for performing the data download & report the possible exceedance occurred. This will be useful for incident/crash investigation. Post data download the system deploys analytical and statistical methods to assess the entire flight data for unusual occurrences, system failures, system performance and also for heavy landings. The ground crew can perform the entire operation using the standalone package within 15 minutes and arrive at a GO/NO-GO for next flight decision with the aid of the Portable Aircraft Turn-Around and Exceedance Identification System (PATEI).</p> |
