The reason it's "deep" is because it's a hole that's hard to get out of. =
 It's a stable regime that is marginally recoverable at best.  However, =
riding it to the ground has not been uniformly fatal, unlike the typical =
"approach to final" stall in conventional aircraft.

  Hi John,
  I think most folks in the canard community regard the stalling of the =
main wings a "deep stall".  The definition would apply to both of the =
situations you describe.

    OK, I need to have deep stall defined.  Is a deep stall anytime the =
main wing stalls, or is it a condition where the main wing stalls before =
the canard?
