What is OBIGGS on an aircraft?
The OBIGGS is a system composed of well-proven equipment generating directly Nitrogen on board to fully protect the aircraft tanks against explosion.
How does Obogs work?
OBOGS replaces Liquid Oxygen System (LOX) by utilizing bleed air from the aircraft engine and separating its components using molecular sieve (Zeolite) Pressure Swing Adsorption (PSA) technology. The system consists of two molecular sieve beds with oxygen plenum to provide breathing gas to aircrew continuously.
Is Steam an inert gas?
The inert gas can then be purged with process gas. Nitrogen is the most common inert gas used for purging. Steam, carbon dioxide, and other inert gases are also used for purging.
What TGL 47?
LEAFLET N° 47 – Guidance on CJAA Interim policy on Fuel Tank Safety (INT/POL/25/12) 1. INTENT. This Temporary Guidance Leaflet (TGL) provides guidelines on the interpretation and implementation for JAA Member States, recommending a common approach for continued airworthiness of Fuel Systems.
What is the main concern of the SFAR 88?
SFAR 88 mandated a review of fuel tank system service history to reveal ignition sources in airplane fuel tanks due to unforeseen failure modes or factors not considered at the time of original certification of the airplane.

How do aircraft oxygen generators work?
Typically, an oxygen canister contains a sodium chlorate pellet or cylinder and an igniter. The igniter can be triggered by friction or impact. It generates enough heat to start the sodium chlorate reaction, and then the heat of the reaction sustains itself.
What does Obiggs stand for?
Onboard Oxygen Gas Generation System. (OBIGGS/OBOGS) Study.
Is Oxygen an inert?
Ahh. Hooray for oxygen, the element that keeps much of life on Earth humming. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth’s atmosphere. Because it’s all around, oxygen is easy to dismiss as dull and inert; in fact, it’s the most reactive of the non-metallic elements.
What is Ewis training?
EWIS is a mandatory training requirement for all personnel operating in close proximity to aircraft electrical wiring systems. EWIS courses are separated out into 8 tiers, referred to as Target Groups, that are designed to cater for personnel with different levels of exposure to electrical wiring installations.
What requirement is present in the INT POL 25 12?
According to INT/POL/25/12, the applicant should perform a Safety Assessment of the fuel system showing that the presence of an ignition source within the fuel system is Extremely Improbable and does not result from a single failure, as per JAR 25.1309 and the corresponding AMJ 25.1309 principles.
What does OBOGS stand for?
On-Board Oxygen Generation Systems (OBOGS) Cobham OBOGS configurations, currently installed in 3,800 aircraft flying today, have accumulated over 7 million OBOGS flight hours – 30 times more than competitors.
What does OBIGGS stand for?
Onboard Inert Gas Generation System/ Onboard Oxygen Gas Generation System (OBIGGS/OBOGS) Study Thomas L. Reynolds, Delbert B. Bailey, Daniel F. Lewinski, and Conrad M. Roseburg Boeing Commercial Airplanes Group, Seattle, Washington
How many OBOGS configurations have been installed in aircraft?
Cobham OBOGS configurations, currently installed in 3,800 aircraft flying today, have accumulated over 7 million OBOGS flight hours – 30 times more than competitors.
Do Cobham OBOGS have an oxygen monitor?
USA 14127. Each of Cobham’s OBOGS is equipped with an oxygen monitor ensuring sufficient oxygen purity at all times for any mission profile. Continuously innovating, Cobham’s newest OBOGS designs come with the oxygen monitor built into the system, reducing system maintenance time and cost.
