Hangar 7 / Re: Pushing the yoke during flare
« Last post by RogerH on Thu, 15 Nov 2018 21:48 »
When I learnt to fly fixed-wing microlight, my instructor told me to think of the stick as being on a ratchet on landing - you can pull it back, but it can't go forward again from that point. When I converted to flexwing microlights, I was also give the same instruction - you can push the bar out, but don't let it come back. So adding pitch-up commands (stick back, bar forward) was taught to be added incrementally but never reversed.

Of course, when one inevitably over-controlled, the brave (and insane) soul trying to stop you from killing everyone, would often override and either arrest the pitch-up control or even add some pitch-down. But I guess that was just to return it to where it _should_ have been pre-overcontrol.

When i read the OP, I was gonna weigh-in with this advice, but glad now I waited to see what the real guys said, interesting - I'm gonna try it in PSX and see how I get on.

Differential outgassing Peter? Didn't you do enough of that during WorldFlight?

Thing is, if this object came from outside our solar system, and possibly our galaxy, is it feasible that it doesn't conform to all of our understanding of physics?

Perhaps it is 'anti-gravatic', repelling rather than attracting...

Or maybe it's anti-photonic. repelled by light?

Just messing around really, but who can possibly say, if it originated outside our system?

We don't really know how gravity works, so perhaps there's another force working here which we've never come across before, but which nonetheless conforms to our version of physics, if we only knew all of it...

Back to the beer and chilli.

"On 27 June 2018, astronomers reported a non-gravitational acceleration to ʻOumuamua's trajectory, potentially consistent with a push from solar radiation pressure. Initial speculation as to the cause of this acceleration pointed to comet off-gassing, whereby portions of the object are ejected as the sun heats the surface. However, multiple objections have been raised to this possibility. Researchers point out that no such tail of gasses was ever observed following the object. Additionally, the anomalous acceleration was not observed when ʻOumuamua was passing at its closest to the sun as would be expected. A follow up analysis of these claims identifies that, were ʻOumuamua a comet, the off-gassing should have caused such an increase in rotational torque as to tear the object apart"

Strange, to say the least :-)

Hi Hardy,

Sorry for the late response.

So it's essential to know whether you tested this stuff with the elevator released, or the elevator pulled (to maintain the altitude).

I do remember adjusting the pitch during the turn but to be honest I cannot remember if there was a difference between the elevator released or the elevator pulled.  Really sorry.  I will ask around when I'm back in the office next week.

That must be what I’ve experienced, Peter. Just didn’t think of it myself as I was more concerned I’m just doing it wrong. :) Funny thing is I often do it if it seems I’m gonna float and then I get a very good landing in the end. It seems it is indeed very different to fly a large airliner compared to smaller aircraft, where the flare as I understand is a simple pull on the stick/yoke.

The 747 feels tricky enough for me at times during the final moments before touchdown. I have either floated or slammed hard many times. When floating, the ac sometimes goes a little off the centerline, and trying to use the rudder to correct it is easy to over control. Another thing I found difficult to manage at first was how much thrust changes affect the pitch attitude.

I guess the 707 was far more difficult? I remember reading how the pilots who flew the first 747-100s praised how easy it is to land the 747. I’m assuming many of them were coming from 707 at the time.

And probably why at a local gliding club the two gliders broken in purpoising accidents took place in flights conducted by seasoned airline captains :-)

It's almost tabu to use a push during the flare in a glider :-)  but I do see it being used frequently in airliner cockpit videos...

I mean... this sort of stuff :

Old 727 Captains will remember this technique as fairly common with that particular airframe configuration (long fuselage, rearward mains and a T-Tail).

PSX never disappoints.

Hi Hardy and Peter,

Another possibility: rotation is slow enough to enable the "lit" side of the object to warm up enough, so that the ougassing always occurs from the side facing the sun... and maintains that acceleration away from the sun?
