Stuflyer Posted September 12, 2009 Share Posted September 12, 2009 Can't tell you WHY, but every Canberra I have seen on the ground, powered down with the locks off, has had elevators in the up position. I surmise effective mass balances. As for Bomb bay colour, couldn't tell you:-( Yet. Link to comment Share on other sites More sharing options...
AnonymousDFB1 Posted September 12, 2009 Share Posted September 12, 2009 Stu is right about the elevators from what I've read and heard. Bomb bay colour, it seems that like U/C bays they were silver, white, green, black... there seems to be no standard. But I will now stand aside and duck to let the Canberra experts come in and tell you for sure. Link to comment Share on other sites More sharing options...
canberra kid Posted September 12, 2009 Share Posted September 12, 2009 (edited) Hi smeds Bomb bay should be silver on RAF 8's, export ones would have started silver too, but would most probably have been repainted white after major refurbishment. The elevators can be up or down I've seen just as many up as down, I think it all depends on how the pilot has them when they are locked.

smeds Posted September 12, 2009 Author Share Posted September 12, 2009 Ta muchly folks. BTW I'm building the Airfix 1/48 B(I)8. Gonna have the bomb bay open with 4 1000lb'ers loaded up and one under each wing. Probably do the kits option of 16 Squadron with sharksmouth. Have'nt done the tailplane mod, but on the next couple maybe. smeds Link to comment Share on other sites More sharing options...
AnonymousDFB1 Posted September 12, 2009 Share Posted September 12, 2009 I think it all depends on how the pilot has them when they are locked. When the locks are in the elevators are level with the tailplane. Link to comment Share on other sites More sharing options...
bexwh773 Posted September 12, 2009 Share Posted September 12, 2009 Can't tell you WHY, but every Canberra I have seen on the ground, powered down with the locks off, has had elevators in the up position. I surmise effective mass balances. The elevators do have rather hefty counter weights in them, and all unlocked elevators I have seen have always been up.

canberra kid Posted September 13, 2009 Share Posted September 13, 2009 When the locks are in the elevators are level with the tailplane. Sorry I should clarify what I said, when the ground locks are in place the elevators are indeed level, but I've seen aircraft parked with the ejector seat leg restraints wrapped around the control column when the locks aren't fitted. So the deflection depends on how they were at the time the driver tied them off. John Link to comment Share on other sites More sharing options...
smeds Posted September 13, 2009 Author Share Posted September 13, 2009 Ejection seat leg restraints are wrapped around the control column for the pilots benefit. If they were just left on the floor he would not be able to reach them on strap in. You will see this on most British jets. I know that on the Hawk for instance, the leg restraints are pushed between the instrument bezels on the main instrument panels for the same reason as above. Its done by the ground crews on flight servivings. Its got nothing to do with "locking" the column / elevators. smeds Link to comment Share on other sites More sharing options...
canberra kid Posted September 13, 2009 Share Posted September 13, 2009 Hi smeds OK, so that blows that theory out of the water! But I've still seen Canberra's parked with the elevators in both the up and down position. John Link to comment Share on other sites More sharing options...
canberra kid Posted September 13, 2009 Share Posted September 13, 2009 (edited) I've Just had a long hard look at my Canberra photo's, and yes the vast majority of British Canberra's do have the the elevators pointing down, but not exclusively, and just to throw a Canberra shaped spanner in the works the B.57 displays the opposite trait!

Les B. Posted November 2, 2009 Share Posted November 2, 2009 I've Just had a long hard look at my Canberra photo's, and yes the vast majority of British Canberra's do have the the elevators pointing down, but not exclusively, and just to throw a Canberra shaped spanner in the works the B.57 displays the opposite trait! Canberra elevators are non powered and operated via control rods direct from the control column. The elevators are heavily mass balanced and on the ground will adopt an elevator up at the trailing edge position. With elevator ground locks fitted and these are quite large alloy affairs painted red and flagged, fitted mid way along the elevators just outboard of the trim tabs. The T4 had a lock that held the instructors seat in the rear stowed position and this lock I seem to remember was attached to the lower area of the control column. This seems to place the elevators in a different position from neutral with the elevator trailing edge downwards. Rule of thumb then: all marks except T4 without elevator locks fitted then elevators in the up position. HTH. Les.B. Link to comment Share on other sites More sharing options...
