Engine RPM Analysis

This tool analyzes aircraft engine data from CSV flight logs to identify periods when the engine is running between 1200-2000 RPM. This is useful for analyzing ground operations and taxi times, filtering out very low RPM periods like engine start/stop.

How to Use

1. Prepare your data: Ensure your flight logs are in CSV format and compressed into a ZIP file
2. Upload the ZIP file: Click the file input below and select your ZIP file
3. Review the results: The tool will display all periods where the engine RPM was between 1200-2000
4. Export results: You can export the analysis results as a CSV file for further processing

Understanding the Results

The analysis provides the following information for each low RPM period:

• File: The source CSV file name
• Start/End Time: When the low RPM period began and ended
• Duration: How long the engine ran below 2000 RPM
• Average RPM: The average RPM during the period
• Min/Max RPM: The lowest and highest RPM values during the period

Typical RPM Scenarios (1200-2000 RPM)

• Normal Idle: Engine at normal operating idle (1200-1400 RPM)
• Taxi Operations: Ground movement between parking and runway (1400-1800 RPM)
• High Idle/Run-up: Pre-takeoff checks and high idle operations (1800-2000 RPM)
• Ground Holding: Waiting periods during ground operations

Note: Engine start/stop periods (below 1200 RPM) are automatically filtered out to focus on operational ground time.
