RIGHT Interniuionnl. 31 July 1976 266 Etiquette for guests LETTERS Why no acceleration c h e c k s ? S I R , — I believe that t h e A n c h o r a g e DG-8 accident, described in " P e r f o r m a n c e m e a s u r e m e n t : time for a c h a n g e " (Flight, July 10), could h a v e been p r e v e n t e d by an o p e r a t i n g technique which had been in use some y e a r s earlier. In t h e early y e a r s of j e t operations a n u m b e r of airlines timed take-off acceleration to lOOkt or, in t h e case of t h e Caravelle. to 90kt. 1 quote some observed take-offs: Elevation (ft) CV-880 12 35 35 81 81 86 90 311 1,414 80 12 80 132 1,563 13 80 744 707-465 707-437 VC10 Caravelle IA* Caravelle V I N * Temp (C) 30 27 29 32 28 21 17 25 24 10 27 5 8 34 36 4 11 15 Brake-release weight (lb) Time (sec) 181,500 165,400 185,000 160,000 188,600 161,500 175,000 190,500 190,000 289,843 251,165 298,605 231,000 279,400 89,760 87,560 100,000 27 25 28 24 26 23 23 29 30 27 28 28 18 25 17 18 23 • T i m e l o 90kt The above figures include elevations up to 1,563ft and t e m p e r a t u r e s as high as 36°C, but in no case does the time to lOOkt exceed 30sec. Yet in t h e case of the A n c h o r a g e DC-8, a t an elevation of 121ft and at very low t e m p e r a t u r e , it took 33sec to achieve 98-3kt. I should like to know why these acceleration safety checks w e r e given up. With regard to runway m a r k e r s , 1 r e m e m b e r seeing these at Dacca as long ago as F e b r u a r y 1962. 41 Park Street, Nairn IV12 JOHN STROUD 4PP S I R , — I t is h i g h t i m e t h a t someone spoke up on behalf of air display organisers about the behaviour of m a n y of t h e people who fly in to t h e s e events by private aircraft. T h e organisers h a v e m o r e t h a n enough worries without having their hard-working helpers (usually volunteers) distressed by arrogance and bad m a n n e r s . The offending private owners fly in with their families, avoiding all the queuing, p a r k i n g and jostling for positions t h a t t h e general public h a s to p u t up with. They g r u m b l e at paying even a small landing fee and try to avoid t h e charity collection boxes. I would say to t h e m : " P l e a s e respond to the privileges you enjoy by securing your aircraft in t h e space allocated. Move quietly behind t h e barrier, respect special enclosures, pay your small landing fee w i t h o u t grumbling, and do not begrudge a donation to t h e charity being helped by the event."

HAI.I Airworthiness Division, Brabazon House, Redhill, Surrey RH1 ISO False Fokkers and bogus Bleriots S I R . — T h e m e e t i n g at Sywcll (Flight, July 17) m u s t have been very interesting. But it does not astonish me that "disbelieving o n l o o k e r s " saw an alleged replica F l a n d e r s monoplane. I am surprised for quite a different reason. I do not believe t h a t any F l a n d e r s had a double invertedV " c a b a n e " (as on early B l e r i o t s ) , or a t r i a n g u l a r fuselage with t h e r e a r p a r t uncovered, or a tail unit of anything like t h a t s h a p e . This, r a t h e r , was a typical British replica. I have seen a Morane-type F o k k e r m o n o p l a n e " r e p l i c a " with a fixed tailplane and conventional elevators, p r e s u m a b l y to appease m o d e r n pilots. Yet I saw Gustav H a m e l do his first loop on a Morane-Saulnier; his first a t t e m p t e n d e d in a gigantic tailslide, b u t t h e all-flying (stupid expression) elevators didn't seem to mind. British replica-makers m i g h t t a k e a few lessons from t h e A m e r i c a n s — t h e i r replicas really deserve t h a t name. 19 Manor Road, A. H.
