Welcome to E-OPS...the proprietary webbased Oxygen Planning Service developed by Aeronautical Data Systems.

Over the past 30 years, ADS has developed a variety of oxygen management products and services for aviation and other industries. E-OPS provides flight crews with an easy-to-use, precise means of planning their oxygen requirements for a given flight.

Long range oxygen planning is dependent on fuel reserves. It is imperative that an aircraft must be dispatched with either:

  1. Enough fuel to fly from the equal time point (ETP) to a suitable alternate at 10,000 feet or below (where oxygen is not required) OR
  2. Enough oxygen to remain at the predetermined altitude (above 10,000 feet) for the required length of time to reach the suitable alternate.

Like fuel planning, oxygen planning is a critical, FAR-mandated responsibility for the pilot in command. Unlike the fuel system, which has enjoyed major technological advances and is supported by multiple flight planning agencies, the equally important oxygen system has been stalled in technology - until now.

Since early aviation, oxygen quantity has traditionally been expressed in pounds per square inch, or PSI. A few aircraft systems provide oxygen quantity in liters, but this is equally difficult to comprehend in terms of duration. PSI and Liters Remaining may answer the question "how much oxygen is in the tank," but what every pilot wants to know is "how much time do I have left (breathing oxygen) before I land?"

Duration or time remaining is universally understood and is the obvious metric of choice. ADS' patented solutions for gaseous oxygen systems are all based on providing users with this key metric: time remaining. E-OPS, the latest of these technological advances, provides pilots with a dispatch oxygen pressure via an easy-to-use online calculation service.

Here's how it works:
