Apparently 558 was run up to 90% power, complete with the howl, last Saturday.
Now call me cynical but after being untouched for 9 months why would they do that?
And bearing in mind the amount of 558 geeks on PH & throughout the aviation world how come the engine run went unnoticed by anyone?????

Given that public can't really access the place as its an international airport, and given the lack of flights happening there, I guess that's why they were able to drag the poor thing and give it a run. Apparently 558 was run up to 90% power, complete with the howl, last Saturday.

I always thought that you needed airflow through the intakes for the howl, and it wasn't audible during a static engine run?

A guy asked the same question on the Facebook post - he got shouted down & banned!!!
I will see if I can find the post & put it on here.
The howl is caused within the intakes, you can actually hear the airflow noise transition before the howl at 90% power. The airflow begins to whistle a little as this happens...
It doesn't need to be flying to create this. Its just airflow into the engines and the slightly restricted size of the intakes.
This only happens on the aircraft with 200 series Olympus engines.
The 300 series aircraft (XM655) have much larger intakes which cured the restriction, thus losing the howl.

There is a long running thread on 'local' Facebook groups however its almost worth setting on up for the gems that are aviation pages. The historic aviation world is a perfect storm of obsessives, nuts, geekery, personalities and politics. And I say this as someone with a garage of WW2 aircraft relics and upteen bookcases of military history books.

As the many thousands of crappy amateur videos of Vulcans taking off at air shows will prove.It doesn't need to be flying to create this. Its just airflow into the engines and the slightly restricted size of the intakes.
