I have no clue about fighter jet systems, but if I was the French Air Force, I would investigate why a system designed to engage both ejection seats once one is activated simply fails and leaves one seat in a somewhat superposition state where it is technically engaged but physically nothing has happened so far. That appears to me to be a risk which should be mititigated. Imagine a fighter pilot on the rear seat (aren't they used for targetting and controlling the aircraft's weapon system?) loses consciousness in mid-air in a combat situation. Plane gets problems and both pilots SHOULD immediately exit via their ejection seats. The conscious front-seated pilot engages his seat's handle and saves his life, but the other pilot won't survive as his seat won't autoactivate (but it should by design, as the article says). EDIT: --- Quote ---a changed center of mass of his airplane (okay, we are talking about ~150kg on a 15 ton jet) --- End quote --- I'm not sure, but don't the Rafale's have autotrim (pretty standard in newer fly-by-wire systems)? So a slightly altered CG shouldn't add that much trouble. |

Those idiots (different air base) are flying over me daily, if I catch an ejected one in my garden he'll be getting my best sympathy for his kind. I must think of getting a heavy dog just in case... --- End quote --- Fighter pilots are known to be fairly intelligent. What do you base your term "idiot" on? When I ask about idiot, my reference is the general usage here in the states which is simply someone with a different opinion than yours. |

I can't find the videos now, but a female pilot of the F14 tomcat experienced an engine failure on approach to the carrier. Instinctively she opened the throttle to the remaining engine to avoid stall, abort and climb out. In the original Tomcat this was a coffin corner on the graphs. So close to stall on the final to a carrier an engine loss needed nearly full power from the other engine to not stall, but full power from the other engine induced a yaw moment so close to stall that it spun. Keeled over and headed straight to the water. The RIO in the back seat seen the situation go critical and pulled the handle, ejecting both pilot and RIO. |
