Are you still considering the ability to itemise maintenance costs ?

I suspect because its use is cheap on two fronts. Firstly, the fire extinguisher itself doesn’t need to be a significantly structured pressure vessel, and secondly because the raw material itself is pretty cheap to make and fairly stable at room temperature. The reason that CO2 comes out cold from an extinguisher is simply through its change in state from liquid to gas as soon as it leaves the vessel (Boyle’s Law). On the other hand, Ammonium bicarbonate absorbs the heat of reaction directly from the fire itself to produce CO2, thereby reducing its intensity, whilst simultaneously starving it of oxygen also right on the fire itself. Other than enclosed spaces such as cockpits, the ammonia would very quickly flash off and generally not be a major issue. The extinguisher of course should be directed at the fire and not at people, although that is not always the case.

Correct ! Ammonium Bicarbonate is not used in CO2 fire extinguishers. It is used in Ammonium Bicarbonate based fire extinguishers.

Aah, thanks - not visible in portrait mode on an iPad mini.

I believe it contains Ammonium Bicarbonate. Ammonium bicarbonate would decompose and release CO2 upon contact with high heat, but being an endothermic reaction, would cool the fire and starve it (and you) of oxygen. It would also produce ammonia gas, which in a confined cockpit would be a problem - but maybe better than the fire ?? So while you are coughing like crazy, your eyes are streaming and your getting hypoxic, don’t forget to fly the plane.

How/where do I access the changelog and ticket system ?

Any chance of adding ‘fuel type’ to the fuel purchase page ? Rotax drivers err toward ULP 95 or 98, but occasionally resort to Avgas. Rotax requires additional oil changes if Avgas is used for more than 30% of hours - hence the need to log fuel type.

Birdog - I sent u an email, but I was primarily wondering how far you want to take this ? I’m looking to be able to itemise and log maintenance costs - but is that getting beyond the scope of your current endeavour ?

Excellent air museum at Caloundra.

I’m wondering how useful an endorsement on a Jabiru twin would be. If you are a CPL and felt you needed a (cheap) twin endorsement, who is going to hire someone to fly legacy twins that did their training in a Jabiru ? I’m not convinced. Not bagging the Jab, just the market positioning.
