Greengears,

Do you think that all flight schools should
have these type of black boxes installed in their aircrafts?


Very bad, to answer your title. One more certified thing to pay for,
with no or little increase in safety (how many GA accidents are there
with unknown cause that have a chance of being clearer with such a
gadget?). The only purpose of such a device is to give the media a
chance to report more in the Lidle case. Sad!
