Talk:De Havilland Canada DHC-1 Chipmunk

message: I found several sources for Chipmunk details, which don't agree, especially on weights. However I've been unable to work out if they were referring to different versions or if not which are correct. Please feel free to investigate further. DJ Clayworth 15:32, 13 Feb 2004 (UTC)

message: Can anyone confirm that the Bulldog did in fact replace the Chipmunk with the AEFs in 96?  I believe
the AEFs came under the control of the UASs at this time, and they both received from Tutor from 99? Sc147 16:25, 23 Sep 2004 (UTC)

text: Not sure they are really notable enough for more than a one liner, with loads of complete flyable chipmunks around and in museums we dont really need to list bits of aircraft. Other aircraft have also been used as simulators and training aids but none are really notable unless the big bit is the only surviving example of the type.

replies: text: I tend to agree, as we have a number of CT-114 Tutor cockpits all over Canada, but they don't get mentioned, nor should they probably.  Bill and I have massaged it down to a couple of sentences in the article - see if you think it is worth keeping or not. - Ahunt (talk) 15:14, 21 July 2011 (UTC)
replies: text: After trying to squeeze the section down, it still doesn't amount to much other than a passing aside, mostly of interest to British enthusiasts. FWiW, I won't mind in the least if the section goes... Bzuk (talk) 15:53, 21 July 2011 (UTC)
replies: text: I think I agree it is not really notable or unusual, perhaps better to remove. MilborneOne (talk) 16:23, 21 July 2011 (UTC)

thread_title:  AEF replacement 

message: Recently reverted: "Many damaged or withdrawn from use Chipmunk cockpits were passed to ATC Squadrons for instructional and educational use. The colloquial or slang name for such a Chipmunk cockpit is often referred to in enthusiast and preservation groups as a "Chippax", an amalagamation of the word  Chipmunk and "Pax" which in itself an industry slang term meaning passenger. Most examples have long since left ATC squadrons finding their way into rebuilds of either whole static airframes, or for restoration by groups, museums and individuals. Some continue to serve as simulators both privately and with some ATC units. Most consist of the main cockpit section from engine bulkhead to rear fuselage attachment point (9 ft in length) but some consist of front cockpit only while others may have approx 4 ft of rear fuselage still attached to aid opening the canopy. Chipmunk's that are the full length (18 ft) from engine bulkhead to tail bulkhead are not referred to as a "Chippax" but a "Chipmunk fuselage."
	
Examples:
* Sywell Museum Chippax WG419 []
* Thameside Aviation Museum Chippax WD471[]"
A, with all due respect, this appears to be more than trivia as it represents a genuine "after use" of the Chipmunk. What do others think? FWiW Bzuk (talk) 14:35, 21 July 2011 (UTC)

message: The article currently states that the RAF's Chipmunks had a variable-pitch propeller, based on this source. However according to Jane's All the World's Aircraft 1951–52 p. 49c, the RAF's aircraft had "a fixed-pitch metal Fairey-Reed propeller", while other sources (i.e. Jackson's de Havilland Aircraft, do not mention variable pitch propellers.Nigel Ish (talk) 14:59, 25 December 2019 (UTC)
replies: text: It is always an interesting conundrum when sources disagree like that. Is it possible that Chipmunks were delivered in each configuration? We can of course indicate that "sources disagree" unless we can find a tie-breaker. Is there a museum in the UK that has one with a good description page, perhaps? - Ahunt (talk) 15:15, 25 December 2019 (UTC)

text: It appears the standard propeller in service was a Fairey Reed A66753/X1 fixed pitch propeller, a list of approved propellers for ex Military British Civil aircraft is listed in CAP562. MilborneOne (talk) 16:05, 25 December 2019 (UTC)
replies: text:  this page from the Pilot's Notes for the Chipmunk T.10 (for which Crown Copyright will have expired) indicates a fixed-pitch propeller.Nigel Ish (talk) 16:17, 25 December 2019 (UTC)
replies: text: The preponderance of the evidence seem to indicate that "Fredriksen 2001, p. 92" is not correct. It is possible that Fredriksen is reporting what the original evaluation of the Chipmunk recommended, not what was finally funded and built. - Ahunt (talk) 16:36, 25 December 2019 (UTC)
replies: text:  The question is what the dedicated sources about the Chipmunk say about the differences between the early Canadian and the British aircraft - we have sufficient sources dedicated to the aircraft (or to de Havilland Canada) that we should be able to use them rather than what appears to be a not terribly good non-specialist reference from what I can see in preview of Fredrikson.Nigel Ish (talk) 14:24, 26 December 2019 (UTC)
replies: text: I agree with that assessment. Let's go with that and disregard Fredrikson. - Ahunt (talk) 14:37, 26 December 2019 (UTC)

replies: text: UK-built aircraft were re-stressed for full-aerobatic use (minus an inverted fuel system) unlike the original Canadian-built design. This was a requirement of the RAF and UK ARB - the forerunner to the UK CAA. I believe the Portuguese-built aircraft also used the "beefed-up" structure of the UK ones. — Preceding unsigned comment added by 86.8.126.91 (talk) 22:03, 16 November 2023 (UTC)
