        As far as too much airflow to be effective, consider jet engines. Much more airflow than we have and yet it works instantly, however it also releases the entire extinguisher contents instantly.

You also have to wonder if you're plane could get off the ground with the size canister it would take to put out a fire like this :-)  

Seriously, the other thing I would worry about is the short term effect of the Halon.  Say you spring an oil leak, it sprays on the red hot turbo, and catches fire.  You instantly shut off the engine, fuel pumps, etc, then fire the Halon.  The Halon snuffs the fire,  then dissipates with airflow.  Unfortunately, the turbo is still red hot, and still covered with oil, so it's gonna flame right back up.  For these reasons, I actually like the dry chemical idea better.
