On 29 Dec 98 03:12:31 , "Hans Jakobsson" <firstname.lastname@example.org> keyed the mic for the PA system and announced in perfect English: >It seems to me that certain types of the Douglas DC-8 is equipped with >spoilers/airbrakes (Super 70 series?).

I don't know about DC8's from the factory(that was a long time ago) or any 70 series 8's, but, I am currently flying various 50's, 61's, 62's, and 63's. The spoiler system on the 8 does not operate as a speed brake system in flight(there is a placard on the handle that says something to the effect,"Do not operate in flight"). The outboard spoilers operate in conjunction with control wheel movement when the landing gear is down to provide more controllability in slow flight(flight regimes with the gear down). The spoilers are armed for landing on the before landing check list. With main tire spin-up, the spoilers will extend on landing. The spoilers can be manually deployed if there is something "not right" with the main gear wheel spin-up or on a rejected takeoff. The inboard engines on the 50-60 series 8's can be reversed in flight to serve as speed brakes. Power can be used up to maximum continuous(I have never used them past "idle reverse"). The gear and flaps must be retracted to use this feature. Speed must be less than 300 knots when coming out of inflight reverse. The airplane shakes a lot when using in flight reverse, it's no telling what is going on out on the pylons. Most dc8 pilots(including myself) avoid using the inflight reverse.

My email address is dc8ray at airmail dot net I don't know if this works or not but it makes me feel better.
