Gen Questions

[Skaz]

I have some general questions that somebody out there might be able to answer for me:

Is there a type of chapstick that you can wear that is compatible with using aviator's breathing oxygen in an emergency?

What type of anti-freeze is added to the water fire extinguisher found on some part 121 aircraft?

more to follow....

You may be under the misapprehension that chapstick bursts into flame when you put on an oxygen mask. It doesn't, as a rule, though any petroleum product can react badly to the presence of pure oxygen.

I've used oxygen in the cockpit and in the ambulance many times, for myself and for those I've been treating...and I've never seen anybody's lips explode.

What type fire extinguisher? Generally glycol, but water extinguishers do freeze. Various types of extinguishers are found. Halon extinguishers don't need antifreeze, nor do dry chemical extinguishers, both of which are used. Interior extinguishers are often water with glycol, though it's not a 70/30 mixture like you might otherwise think of antifreeze.

water fire extinguisher

3. does getting rated on the CRJ-200 cover you for the 600 series challenger too?

4. there was a link to a movie file of a F14 going supersonic and then exploding, here on flightinfo, anybody knows where it is?

5. any links to exploding aircraft ? like for bomb damage resistance testing etc?

thanks

Why this sudden interest in exploding airplanes and fire extinguishers?

I don't recall a video of a F14 exploding. Are you perhaps thinking of a vapor formation along a shock wave as the aircraft pushes critical mach?

I've seen the video of the F-14 exploding after a high speed pass (near/at the mach) over water near a destroyer.

The Tomcat threw a compressor blade, which did something like sever a fuel line as it exited the aircraft. The resulting imbalanced rotor and fuel spillage caused a pretty impressive fireball. Both crewmembers ejected as they were engulfed in flames in the cockpit. Nomex saves another couple lucky aviators.

I think that's called having a bad day.

I haven't seen that one.

fury220 - thats the one I'm talking about, you know where it is?

 

[BD King]

The word was emergency. At that point, ya don't care.
