How close?

Sorry guys – I had glugged a couple of glasses of Monkey Shoulder last night and it had made me a little giggly 😀

I believe that the mod to the B Angels a/c that DF referred to is actually just a spring fitted to the control system – not so much to give it a nose heavy bias but to take out backlash/play in the system to make the flying controls feel taut/less sloppy !
A similar but smaller spring was sometimes used on potentiometers in flight test instrumentation – the spring tension held the backlash/play onto one side of the lever/or attachment which meant that all readings/indications were consistent and therefore it reduced hysteresis in the system recording/readings.

Just to finish about F18 tailplane trim – as far as I am aware it has 2 basic modes…
Fully auto with gear up
Manual with gear down

There may also be a standby trim system but not sure !

Tailplane trim? On FBW?

Yes 😀 and No 😀

Or perhaps I am ‘biased’

I could ‘stretch’ a point

Same thing done different way,aileron trim on the canberra was a bias spring,those springs get everywhere ; )

Edit to add – I suppose I should specify pre PR9 Canberras as different FC system on the ‘9’

It might be called tailplane trim ; )

Tailplane trim? On FBW?

I did read somewhere that the FBW system on their F-18s was modified so that there is always a small pull force on the stick .

It might be called tailplane trim ; )

If I was uncurrent in gliders (ie had not flown for a while ) – I used to trim the glider slightly nose down so that if I inadvertantly got distracted etc whilst thermalling then the glider would tend to speed up a little which is on the safe side.
I believe some pilots who used to do a lot of low level flying over water used to do the opposite and dial in a slight nose up trim force so that if they got distracted etc – the a/c would tend to climb slightly instead of possible water contact !
Some people call this the ‘Sneeze Factor’

Remarkable skill and a testament to their training. I did read somewhere that the FBW system on their F-18s was modified so that there is always a small pull force on the stick – they also don’t use g-suits or oxygen masks.
About time the Blue Angels made another UK appearance – I last saw them in 1992 in dismal weather at Finningley.

After watching it again…..YES! 🙂

I somehow think the latter, don’t you……..?

Just a thought: those are single-seat F-18 fighters, yes…

…and that camera is being hand-held? HOTAS? :rolleyes:

Edit: Possibly it is a helmet-mounted Go-Pro camera?

Still room for a Red Arrow to squeeze in 🙂 All good til it goes **** up then you end up with a multi multi multi million dollar pile of metal.

High speed close formation flying is dangerous. The question to which there is no objective answer is where do you cross the perceived boundary betwee sensible and silly?

Silly….as somebody posted on prune – how would you be able to eject out of that lot ; )

Stunning!!
