Elevator and rudder trim

[THibben]

Both trim wheels indicate in +/- %. The check list has 11 o'clock and 2 o'clock. What is the relationship between time and %?

This sounds like a dumb question but is it based on +/- 180 degrees vs +/- 12 hours?

Thanks,

Tom

Hi Tom,

Yes it's based on 360 degrees being 12h. Imagine the face of a clock on the trim wheel. So 12 o'clock is straight up, 6 o'clock Is straight down. 1 o'clock would be nose down to where about the hand of the clock would be at well 1 o'clock (30 degrees clockwise from straight up). Two o'clock is even more nose down (60 degrees from close clockwise from straight up). 3 o'clock would be 90 degrees clockwise from straight up and so on.

So 11 o'clock means nose up trim with the pointer at about "11 o'clock" position or at an angle 30 degrees counter clockwise from the straight up position.

I'm sorry but I can't think of a better way to explain it

Hope this helps though

Hi Piper,

Thanks for the info. I assumed that is what it is. It would have been a lot easier if they just said +/- so many degrees up or down....grin

Thanks again,

Tom

Well I guess they didn't say that because there is no scale on the trim wheels and the real aircraft doesn't have the tool tips 11 o'clock is probably what the real manual says.

Happy flying

Yeah, I find "11 o'clock" easier to visualise than 330 degrees or some percent figure. However, I seem to recall I had something like this...



...when I was a kid, so I clearly wasn't the sharpest tool in the box!

Yup same here nick, grew with my aviation love being military based, in particular ww2 so the clock and up or down is what Ive always known, bandits 2'oclock low, tally ho!

Hehe nice watch. I still wear analog watches. I can just read then quicker I feel like.

Yes true. My first game was "Luftwaffe Commander" and then of course I spend countless hours with "IL-2".

Did you ever read the Matt Braddock stories Lewis? A bit before your time (and mine too) but classic comic strip stuff from The Rover, which I got hold of as a small lad in the form of a book called I Flew With Braddock which had belonged to my Dad. I loved that book, and it was responsible in part for an early fascination with the Lanc and Bomber Command.

Actually, I'm afraid I got a 'proper' watch when I got a bit older Sebastian: Casio digital was all the rage! It's been a while since I've bothered wearing a wristwatch at all though. Nowadays I just draw my mobile phone out of my waistcoat pocket when I need to tell the time. I'm seriously thinking of keeping it on a length of gold chain, like a proper Victorian gent!

That's funny. The digital wristwatch thing never caught on with me. I just like them analog. Made me not the coolest kid in school but who cares I really like the analog watches when flying in RL because a short glimpse tells me everything and I can set the ring around the face to the takeoff time and stuff. It all comes down to personal preference I guess.

Good idea with the gold chain for the mobile phone just make sure you don't damage any important parts when drilling the hole the attach the chain

If I drilled any holes in my phone it would no longer be waterproof. Oh well____ such is life.

Never read those Nick, but my nan gave me my uncles old books to read when I was a nipper and I remember two where from some series, one story was about a matilda II tank in France 1940 and its quest to get to Dunkirk the other was the story of the LRDG in North Africa, I loved them! Cant remember the damn series name though, I think the main character may have been the same person in both.

The Matilda book you're thinking of Lewis may have been "Tramp in Armour". I read that one a million years ago. By Colin Forbes (Ray Sawkins) Sawkins served in North Africa. I don't remember an LRDG book but that doesn't mean much, given my memory these days!

[Lewis - A2A]

OMFG yes! Thankyou so so so so so much that was it, Colin Forbes books. So amazing to read, like a next level biggles for a teenager, loved them so much!

cheers,
Lewis
