ETOPS Planning Helper
Calculate ETOPS equal time point and diversion distances
Inputs
Provide the following 3 values to run the ETOPS Planning Helper:
- Route Distance (nm) [number] (required)
- Ground Speed (knots) [number] (required)
- ETOPS Time (min) [number] — default 180
What it calculates
This tool returns:
- Equal Time Point (nm) — primary result
- Max Diversion Range (nm)
- Flight Time (min)
Worked example
For the sample inputs below:
- Route Distance (nm): 1000
- Ground Speed (knots): 450
- ETOPS Time (min): 180
the ETOPS Planning Helper produces:
- Equal Time Point: 500 nm
- Max Diversion Range: 1350 nm
- Flight Time: 133 min
How it works
The result is derived through the following steps:
equalTimePoint = routeDistance / 2maxDiversionDistance = (etopsTime / 60) * groundSpeedflightTime = (routeDistance / groundSpeed) * 60
Frequently Asked Questions
What is ETOPS?
ETOPS stands for Extended-range Twin-engine Operational Performance Standards, allowing twin-engine aircraft to operate on routes that are more than 60 minutes away from a suitable airport.
How does the ETOPS Planning Helper tool work?
The ETOPS Planning Helper tool calculates equal time points and diversion distances based on your specific aircraft, flight path, and emergency landing scenarios.
Why is calculating equal time points important?
Equal time points are critical for flight planning as they help determine the optimal points for potential diversion in the event of an in-flight emergency.
Can I use this tool for any aircraft?
Yes, the ETOPS Planning Helper tool is versatile and can be used for various aircraft, provided they meet the ETOPS certification requirements.
What are the benefits of using the ETOPS Planning Helper?
The tool enhances safety by providing accurate data for emergency planning, ensuring compliance with regulatory ETOPS requirements, and optimizing flight routes.
