Glanzed tip

The redesign is mentioned twice, once for 1947 and once in the prototype testing in 1949. Which of these is correct? Ciao -- Pentaclebreaker ( talk) 06:07, 29 September 2020 (UTC) reply

Losses?

Are any operational loss statistics available? Mztourist ( talk) 05:20, 30 November 2020 (UTC) reply

Should the Gate Guardian (PR9 XH170) at RAF Wyton be included?

1952 British Canberra in northern california

There is an existing 1952 mark 4 English electric Canberra sitting at redding municipal airport in redding, ca. 2600:6C5D:4D00:365A:105:60B4:8704:D78A ( talk) 19:43, 23 October 2023 (UTC) reply

Error about surviving aircraft

Near the beginning of the "Surviving aircraft" section, it says this:

"Several ex-RAF machines and RB-57s remain flying in the US for research and mapping work. About 10 airworthy Canberras are in private hands today, and are flown at air displays."

But down the page a bit, under "Australia", it says this:

"The museum’s Canberra is now the only airworthy example in the world, apart from three that are still in use with NASA for research purposes.[202]"

Clearly, something somewhere needs to be reconciled or corrected. TooManyFingers ( talk) 05:56, 11 May 2024 (UTC) reply

Centre of gravity

"The new engine position decreased the aircraft's weight by 13% and improved the aircraft's centre of gravity, as well as improved accessibility to the engines and related accessories; its downsides were slight thrust loss from the longer jet pipes and greater yaw during engine-out instances."

What does "improved" mean? S C Cheese ( talk) 20:25, 16 May 2024 (UTC) reply

I don't have the source so can't adjust the wording but it would mean that the centre of gravity moved forward, an aft CofG gives controllability problems (prone to stalling/spinning etc). A very forward CofG also causes problems (elevator ineffective) but not as bad as the aft case. Designers specify a dimensional range for the CofG position and confirm it through flight testing. Center of gravity of an aircraft is the article that covers this. Nimbus (Cumulus nimbus floats by) 09:22, 17 May 2024 (UTC) reply
"Improving" it simply means the thing flew better afterwards than it had before. But I agree with your real point, that the statement you asked about is uninformative and not well thought out. TooManyFingers ( talk) 23:51, 24 May 2024 (UTC) reply
