Sniff , I have been involved with 'Warbirds' off and on since 1990.I have never seen 'solo weights' on our Harvards.I cant recall either the Roaring Forties displays or any (WB) Solo routine with weights fitted to the Harvards. Will make enquiries and let you know. Also common practice is to remove rear seat cushions and fasten all seat straps together and pulled tight to prevent anything untoward happening. Common practice for WB but only 'recent ' for the RNZAF Harvard as Jim Rankin mentions in a recent article in Vector magazine.Cushion got caught between cockpit structure and rear cockpit control column with almost disastrous results.
Not the first time a Harvard has taken off with luggage locker door not secured either.
Très Interesting! Standard procedure for solo back in'74 was: Solo Weights, Straps in rear locked (coz parachute stayed in the rear seat) and Rear control stick stowed in the starboard (or was it port? I think so) side of fuselage (presume the locating ring is still there???).
Havent seen the Vector article. Was the c/c in situ or stowed? Was that in NZ1015 or a civvy Harvard?
Dave, if I have got it right (coz I'm not a subscriber) it is the logical government department's safety magazine. It comes in multiple languages now, I believe, so kiwis can practice for the $99 test!
Unfortunately I dont have the said magazine at hand at the moment .But I think the rear stick was in the stowed positiion.
As I understand from John Lanham in the Airforce days they were particular about dual and solo scenarios.So I guess flying solo, then have weights fitted. John continues by saying that he flew the solo Red Checkers routine with solo weights fitted and full smoke tank .He also ferried Dual with weights and smoke tank. The C of G was not sensitve and could be compensated with trims.
None of the WB Harvards I have seen or heard about have any weights fitted internally to compensate for Solo aerobatic weights. As for the RNZAF Harvard NZ1015 I dont know of any weights being fitted .So I guess that one question for the pilot next Airshow. I dont think the Harvard has really any C of G issues anyway.
Thanks Damon, I trolled back through a few, but couldnt find the article. Agreed, the frame can be trimmed for most things, solo weights were probably designed for 8 to 10 hour novices in a 600hp beast. But then, how much experience do current Harvard pilots have, particularly during type qual?
Sniff ,finally found the article.CAA News/Vector July /August 2002. We're a bit off topic here. 'The control column was stowed, but seat cushon still in place.Controls moved normally left but met resistance when moved to right ie no movement beyond centre.'
Jim landed (Ohakea)with ' high control force to the right and near full rudder required.Touch down was quite nice ,but as aircraft slowed control authority was lost.' 'And veered a little left on runway'. Pilot and a/c OK.
The article is descriptive and quite long ,and I dont posses fanstastic typing skills.As mentioned the seat cushion was at fault and had lodged between control column stub and fuselage structure.
No mention of Solo weights in the article so can assume for time being that none are fitted.
