ADS shows O2 applications

Oxygen bottle levels are an important preflight item, but even with a full bottle, pilots still need to do some calculating to determine if there is enough oxygen for a planned flight and in case of a diversion. Aeronautical Data Systems (ADS), exhibiting at the Pacific Precision Products booth (No. 2341), has a simple way of evaluating oxygen needs–a program called E-Ops (electronic oxygen planning service) that is available on the company’s Web site.

ADS is demonstrating the program and a new iPhone app called O-2 GO-2 here, but the app won’t be available on the Apple iTunes store until a few weeks after the show, according to v-p Jim Stabile.

We tried the Web version of E-Ops using Google’s Chrome browser, and it worked fine. E-Ops is running as a beta test program for now using a Dassault Falcon 900EX for the calculations. ADS can add other aircraft types to the system if you want to see how it works on your company’s aircraft.

We logged onto the ADS Web site, clicked on the E-Ops button, and a small window popped up with three data fields: user ID, password and N-number.

A larger window then appeared with fields for:
• aircraft type and tail number
• flight altitude
• number of crew
• number of passengers
• equal time point (ETP, to suitable alternate)
• number of oxygen bottles and size
• crew mask type
• passenger regulator and
• passenger mask PSU.

After filling out these fields, we clicked on the submit button, which revealed the minimum required oxygen cylinder pressure needed for dispatch. At 25,000 feet with two crew and no passengers and a 3:15 ETP, the minimum was 1,108 psi. Adding six passengers under the same conditions we got this message: “WARNING: oxygen deficit 1834 liters.” With two crew and two passengers, the minimum cylinder pressure was 1,701 psi. Pricing is not yet available.
