In this flightlevel350 video, the 747 uses the outboard reversers onlythought that was neat. At least that's what it looks like.http://flightlevel350.com/Aircraft_Boeing_...Video-5892.htmlJimCYWG

Most likely one of the inboard reversers were deactivated due to a problem which makes the other inboard symetrical one unusable as well.Cheers,JohnBoeing 727/737 & Lockheed C-130/L-100 Mechanichttp://www.sstsim.com/images/team/JR.jpg

WOW. Neat stuff. Thanks John.JimCYWG

The A-380 only uses 2 but they use the inboard engines. Don't know why! I would thik you would want all the stopping power you could get to slow down that monster!!

The A380 has reversers on the inboards only due to possible FOD ingestion on #1 and #4 engines as they hang a significant way over some runway edges and produce a lot of thrust. Also, the use of reverse thrust isn't taken into account on landing distances(Southwest Airlines does on their NG's but that might not be used anymore due to their Midway accident). It's not that reverse thrust isn't effective, it's just not as consistent as braking is so the regulating bodies, FAA, CAA, JAA etc., don't allow it in landing calculations.Cheers,JohnBoeing 727/737 & Lockheed C-130/L-100 Mechanichttp://www.sstsim.com/images/team/JR.jpg
