One argument for designed gear doors to be open during
landing approach on an aircraft carrier would be that the aircraft jet engine would run at higher RPM during approach which reduced spool-up time for a bolter or wave off. At least, spool-up time was a real concern half a century ago when we trapped under the mizzen mast sails on the poop deck. WDA end "Mary Shafer" wrote in message ...

While typically (or at least in most other military jets), some of the landing gear doors open only during extension/retraction, and are closed while the gear are extended. The F-111 MLG doors open, the gear extends, and the doors shut. Mostly because otherwise these huge doors would be hanging out being speedbrakes. F-4 doors stay open. So do F-15 and F-16 and B-52 doors. Ditto YF-12, SR-71, T-33, F-104, X-15, F-18, CV-990, A-7, F-8, KingAir, B-747, B-1, B-2, F-117, B-57, and U-2. Also Lear 24 and 25. And the Orbiter. These are just the ones I've seen and can remember. I'd say it's not most, military or otherwise. -- Mary Shafer Retired aerospace research engineer "Turn to kill, not to engage."
