FDM 301

Achieve proficiency in FDM/FOQA artificial intelligence

Learn how to apply ai, neural networking, and modern data science to support next generation FDM initiatives. You’ll attain expertise at transforming & presenting ‘big data’ and ‘flight data analytics’ in financial, business, operational, maintenance, and performance reports, which will faciliate the decision making process for your flight safety executives. Become the driver behind meaningful flight safety improvements and increased operational efficiency.

Prerequisite:

Make your FDM program intelligent!

Reactive Benefits

Learn how to properly react to events & exceedances within the context of the complete operational environment

Proactive Benefits

Become adept at developing statistically based action plans and corrective actions to improve safety and mitigate risk

Predictive Benefits

Benefit from advanced event, incident, and accident predictive science by become proficient in artificial intelligence based FDM

When you grasp the essentials of artificial intelligence based FDM, you will begin to understand the limitations of your current FDM software and program. As an example, pilot fatigue – a major causal factor behind many events and incidents – cannot be measured by employing standard parameters and variables. Rather, the science and application of correlatory data aggregation, dependent and independent multivariate analysis, and crew scheduling data, are all needed to detect pilot fatigue in advance. FDM 301 provides it all.

“Words can’t explain. After training the flight data neural network with the massive data set provided, we were able to predict the approximate latitude/longitude and altitude on the LDA approach where unstable approaches were most likely to occur. This will aid us in briefing our pilots in advance in order to increase awareness. These Flight Data X instructors are amazing!”

How do I modify my FDR to record more than 25 hours?

You can modify the program pins at the rear of the SSFDR to uptick your recording hours. For example, if you have a Honeywell PN 980-4700-XXX installed, you can alter the ‘ground/open’ discrete wiring at pin 17 & 18 of the SSFDR mating connector to increase your recording capacity.

How can determine the amount of hours recorded by my FDR?

The amount of recorded hours is dependent on a combination of your FDAU wps output and FDR maximum allowable recording speed. If there is a one to one relationship between the two units, i.e. – 64 wps FDAU with a 64 wps FDR, you will record the last 25 hours of flight data. This also applies to the case when the FDAU and FDR are both 128wps, 256wps, or even higher. If there is a mismatch between the FDAU and FDR speed, a small and simple calculation can be made to determine actual flight hour recording capacity. See the figure below for the various possibilities:

How can I determine the speed of my Flight Data Recording system in words per second (wps)?

There are basically 4 ways to determine your speed, with the 4th being a bit more involved. First, the speed should be listed or documented in chapter 31 of your aircraft Maintenance Manual and/or Wiring Diagram Manual. However there are times when for some reason, the required information cannot be found. If this is the case, as a second method, you may reference the CMM or technical specification for your Flight Data Acquisition Unit (FDAU). If you are still unable to find this information, you may contact the aircraft manufacturer for the wps or review your previous FDR download analysis reports. Please keep in mind, the OEM will only know the as-delivered configuration of your aircraft. If there were modifications to your aircraft post-delivery – manufacturer unaware of the changes – youll need to contact us for an analysis of your raw data. Using our software we can determine the wps of your system.

With regard to Flight Data Recorder Systems, what exactly does wps imply? I have noticed this abbreviation in our FDR documentation and in communications with the manufacturer several times:

WPS = words per second. A word (12-bits in length) contains binary data which represents a specific parameter value. Please see figure 1 below. Your FDR records in frames (4 second intervals) and each frame contains 4 sub frames (one sub frame = 1 second). With each second that goes by a specific quantity of words are recorded into memory. If you operate a 64 wps FDR system, you will record 64 12-bit words in one second. The higher the word capacity the more information you can record.

What is a Dataframe Layout (DFL)?

A DFL, also known by the name Logical Frame Layout (LFL), Dataframe Interface Control & Requirements Document, and many other names depending on the manufacturer, is a document which specifies the FDR, QAR, or DAR Parameter Word (location), Recording Speed, Sampling Rate, Bits, and Conversion formulae for your recording system.
