Airborne engine monitoring systems Courtesy of Hawker Beechcraft Corporation H384, H484 & H598 Series Airborne Engine Monitors A vital component of condition-based maintenance, Howell’s health and usage monitoring systems help flight crews: • Troubleshoot problems by isolating abnormal performance • Reduce maintenance cost and system damage through early diagnosis • Reduce parts replacement • Improve maintenance scheduling and logistic support • Improve incident or event analysis • Eliminate errors in data recording and analysis • Establish critical engine condition and trend monitoring for enhanced performance Parameters include: • Engine Temperatures • Pressure Altitude • Engine Speeds • User-friendly software prints a report, formats the data into useful graphic presentations or transfers it to other computers. The data can be stored to maintain historical records. • Our patented Referred Engine Diagnostic Data (REDD)®1 software package provides detailed analysis and diagnosis of processed data. REDD® software quickly determines actual engine condition by calculating and displaying variances between an ideal engine and the monitored engine. • Monitors display data for a quick check of parameter values, or data can be downloaded to a computer for more in-depth review and analysis. • Bleed Valve Position Our monitors retrieve and process data in several ways: • Fuel Flow Data Reduction Howell Instruments, Inc. 8945 South Freeway Fort Worth, Texas 76140 www.howellinst.com 817-336-7411 Fax: 817-336-7874 [email protected] 1 REDD® is a register

TREND DATA Trend data can be recorded manually or automatically during flight. The monitor records all relevant parameters along with the date and time. The data can be formatted for use with an engine manufacturer's approved software or with Howell's own patented trend software programs. Monitors detect an exceedance and record the time of the event, its duration, peak value, values of related parameters, and if applicable, the maintenance level required based on severity. Monitors can also recall related parameter values leading up to the event from a buffer. These values are stored in memory...
