You can do it either way but I hate controlling speed with elevator now, it's such a clumsy way to do it.

Don't try and think I'm being a smarty! I'm just very interested now in how you do it with power only?

We are all here to fly because we love it, we are all here to support each other - aren't we?

Wow! What an interesting bunch of topics....!:thumb_up: (took a while to read through it all though!!)

But, I agree very worth while things to discuss.

From what I can gather from this attitude/power/stick/nose, approach thingo.... you are all saying the similar thing, but in a few vastly different ways!

Power does control descent/ascent, just as much as the elevator does, and power does control speed, just as much as the elevator does....

Without power (thrust), you ain't going nowhere - forwards or up while you're on the ground are you? Add power (thrust)... yeehaa we have speed! but someone pinched the elevator!! Oh man! ( No doubt you will eventually fly same way or another but with no control what so ever...;) )

Ok, so we survived the crash, and have fixed it up, making sure we have elevator this time! Add power (thrust) to increase speed (Oh dear we have speed with power only!) So we ain't going nowhere in particular (except toward the trees!) until we pull on the stick increasing AoA - Thrust + AoA/surface area (an all the other bits an pieces!) = Lift

This pilot having watched to many jets take off pulled back on the stick so much the nose (attitude:ah_oh:) is pointing way up... suddenly realizes his airspeed is decreasing dramatically.... (but we have full power!!?? (thrust) ) On a sudden impulse he pushes the stick forward and the nose (attitude) lowers to a more respectable position and we suddenly see the ASI winding up!:thumb_up:

Now having gotten over his first fright of the day, he starts experimenting.... Level flight he pulled the throttle off... nothing much happens.... ... ... ... then it suddenly starts to sink, Oh no! Quick, quick he thought push on the power (speed?)... only to find the engine had stopped completely :ah_oh:. The speed was getting awful slow.... ... ... ... Stick forward! that's it! Yay! we have speed.... but we are still descending??? (elevator controls speed AND descent?!)

He finally gets the engine going and pushes the power on full! Man!! that speed is going like crazy, and we're still descending?? (with full power?!) Quick pull back on the stick! Yay, we have lift... and look at that! our speed is decreasing to a normal rate!

So saying it like that, we need to use both together, not one or the other... just like aileron, rudder, elevator...... they all do their respective things, but are a ton more effective when working together.

Some aircraft are a lot more susceptible to it one way or another... the Drifter for example drops (almost) like a rock without engine (thrust), whereas the Jab has quite a lot of speed up its sleeve, and so when the engine stops, or go's to idle, you have quite a long time to figure out what to do... (In the Drifter on climb out with two up, you have about 1, maybe 2 seconds to lower the nose before you stall cold.)

So on finals, I have my aiming point, a rough guide to make a nice smooth approach (rather than going down a staircase). I see I'm undershooting it and the threshold, so I put a dribble of power on, but also pulling back a little to stop from speeding up... and also to change THE aircrafts aiming point to MY aiming point. Same if I was overshooting, I decrease power (if there is any to do that, otherwise sideslip), but not only do I decrease power but also lower the nose to maintain my approach speed, thus changing THE aiming point to MY aiming point.

So you can see we use both simultaneously, whether we are pointing the nose at the aiming point and using power/less power to get there, or just randomly flying an approach without undershooting!

So why does the aircraft pitch up (climb) when power is added? Go's back to the Thrust + AoA (and the other bits) = Lift. Adding thrust (speed) is going to (obviously) create lift, and because the aircraft was in a slower faze of flight before the power was added it had a larger AoA or higher nose attitude to start with to maintain altitude and airspeed, so with even more power (thrust) (speed) it will want to climb, making us push the stick forward 'decreasing' the AoA to maintain level flight.

Same with decreasing the throttle, it slows the aircraft (lessens thrust) so the AoA or attitude has to be raised to keep a level attitude, but the airspeed will decrease... So you can see where that is leading. So Power (thrust) DOES change altitude, Elevator DOES change speed. And Power (thrust) DOES change speed, Just like Elevator DOES change Altitude. But to render it effective you need to use both together, do you not?

Basically if you go with one way or the other you are agreeing with each other anyway, because one can't be used without the other. If you know what I mean! :big_grin:

Just my 2.35cents worth :big_grin:

...was, 'to say the least,' fully loaded!

The poor 914 was having trouble with it's water cooling device, whilst the 3300 was purring along quite content...... Santa was desperately trying to recollect his training on what to do with a sick engine - the sledge was still yawing frighteningly to one side.......

Looks good mate! nice work.

..... something fell out of Santa's Sledgstar, hurtling towards the front windscreen at an extremely fast rate of travel! Putting it into a steep turn the jabiru swung around hard to the left, the piece of something whistling past the window.... geee's that was close muttered tomo, nearly had a broke prop and no doubt a broke nose and windscreen!

He then noticed santa was frantically doing something... his panic was obvious and he seemed to be having trou........... Oh!....................

Yeah right? Well I shouldn't have to much trouble finding anyone by the look of it... Will just have to work out when I'm might start now......

Only you could keep the parents fooled for so long Tomo.

They don't need to pedal... it's got an engine!

....Drop down through space to earth below, Tomo kicking the 80 odd horses in the ribs up front dived down and followed him.....

=====

note: tomo will be going away as of tomorrow for a while (week).... just a courtesy note for the NES's that I haven't abandoned them completely!!

Well, apparantly I've been deemed too old for Santa to come.

I have to say they do look like a lot of fun!

it's awesome -

according to the "Naughty, Nice" calculator... I've been nice!

Darky,Do you have a URL for that?

 

I would love to send it to other people.

Darky beat me to it!

Hah! :thumb_up:

Very Insightful

That's awesome Alison! I'm sure you'll be the happiest girl on the planet! you'll love the 230's they are a nice machine to land!

Have a Happy Christmas, and don't forget to take some pictures of your 'Girl' for us to see!!

Congratulations :thumb_up:

Hey! G'day Thalass,

Welcome along, we are glad to have you. I hope you find it helpful with your flying and building process's. Once you start the flying training you'll find it hard to stop!!

Have fun, keep safe :thumb_up:

awesome vid mate, well done! :thumb_up:

Nice video, i might get some of those tiny mountable cameras and put onto the gazelle once i start formation.

This particular video was done with a still camera actually! that is why it is a bit slow at focusing... He just held it.

I hope she clean it up properly afterwards.

Tecnically, what most of you are talking about are tail wheel a/c. I was corrected in no uncertain terms by a trial dragger owner. There is a difference and I for one dont want to put any tail dragger owners off side. I am still looking forward to my first flight in a tail dragger after many hours in tail wheels.

I call it the aircraft personalities... each aircraft has its own little thing, each aircraft handles a little differently, some are more comfortable than others, look better, handle better, fast, slow.... stick, yoke, trike, tailwheel... to me it's not a like/hate thing, its just enjoying each personality... Though I probably wouldn't fly to Perth in the Drifter if I had something faster available!

But if it's strong, built properly, and handled properly... you'll probably get me into it! (a bit of reliability has to come in there also!;))

But come to think of it... I fly for fun... so it doesn't really matter ATM!! :)

Thanks Qwerty!

... poor Tomo was quite unimpressed by his current position, and tried to work out how he's going to rectify it.

Problem was; there was a slight leak in the trusty Jab cockpit resulting in loss of usable oxygen; it was getting unspeakably cold, the engine had stopped and I was floating past a fandangle looking satellite with all the bells and whistles - but clearly out of reach...!

Fortunately I had with me a satellite phone so I could contact the NASA head quarters to ask for help...

To which they replied.......

Thanks all!

Yes I will certainly take more notice next time when around that sort of thing! Lesson learnt!
