Force Feedback.

It wiggled and vibrated when I flew poorly and stalled.

I flew poorly alot.

I use an X52 now.

Wife took the feedback stick.

Shubie,
You sure bout that?  I was the Chief Pilot of a Piper dealership in the mid-late 70's.  I picked up our first new Tommahawk and we were kinda excited because it was the first low wing Piper approved for spins.  Up till then, I gave students spin training in a Great Lakes or Citabria.  I spun that little Tommy on the way home a few times and it was pretty squirelly but I was mostly worried bout the tail comin off.  It was a pretty violent stall/spin for a primary trainer.  Did they possibly revoke it's spin certification later on?

I've never actually been in a spin in a real AC, I generally try to avoid those if at all possible LOL, of course I don't have a nice little Pieper like that, if that was the case I might play around in it a lil, I like low wing AC there so much funner, you actually feel like your cutting through the air, vs the feel of a glider from high wing such as a 172... I think any plane that is on the verge of a stall should feel a little buffeting as the flow of air is disrupted... I'm not an aerodynamic specialist or anything so I could be wrong

I'm sure someone like Golfer would know more about this than me, they have allot more experience than I do flyin real AC

Yeah, they did after it killed several people.  It turned out that if you had a forward cg (within limits, typical of pilot and instructor) there was an "unrecoverable spin mode" if you made more than a couple of revolutions.  I think they also put some stall fences on the wings to try to fix the problem, but as far as I know you still can't spin a traumahawk.

Some airplanes are better than others.  In a C-172 ('69 K model - 2005 G1000 Equipped) they've all been *****cats in slow flight, stalls and spins.  Depending on the airplane, some would give you a buffet a couple knots above stall speed and some the first sign of the detatching airflow is a little shake and a the break.

In my opinion (and 1000's of stalls...bllllleh!) If you're doing a power-on stall you're likely to feel a little buffet because you will spend a longer time slowing down than you would holding your altitude in a power-off stall.  It's also a good chance Iceman that you've never done a stall when someone else was doing it.  You can actually sense much more about what's going on when you're just sitting there.  For instance, I had a student not long ago who was making 60º bank turns every time he made a course change.  I let it go a few times thinking he'd get it, but after 5 or 6 nothing was changing so I asked if he knew how steep his turns were.  He replied 30º...the wrong answer!  I took the airplane and did a few of his turns at 60º and he couldn't believe how steep it looked when you didn't have the controls.

Back to the buffet...

The most fun airplane to fly around in slow flight for me was the PA-23 Apache.  When you got it slowed down and were doing slow flight properly...you had the "whomp whomp" of out of sync propellers, the stall horn (a god awful screaming noise) and a good buffet.

The Marchetti F-260 (think Air Combat USA) is probably the "most similar" airplane to what we have in AH that I've flown.  That airplane with it's thin wing would really get into a buffeting fit if you overloaded the wing even at 180+kts coming out of a downline.  RV6 kicked my butt that day as it was my first time in anything other than a Cessna, I had a student pilot certificate and he's got maybe 40 hours or more of Marchetti time (It was a SETUP!!!!  I got hustled:D ) but when reviewing the tapes on each turn I'd load up the airplane and get the buffet and was a little slow getting out of the buffet.  RV6 on the other hand flew right to the edge of the buffet, rarely went into it for any appreciable length of time and as a consequence, turned more effectively and shot me down repeatedly.  I was complimented by the instructors on some of my evasive maneuvers and it was kind of neat to see me side by side with RV6's gun camera footage actually rolling left over/around his pipper and then diving back down under to the right trying to get away.  There was a vertical scissors thrown in for good measure and a little "loss of separation" a few times that the IPs let slide all but once (probably inside of 100 feet at one point...the one time I was on his tail!!!:cry )






Aaaaanyway, there are (at least using mitsu's sound pack) buffet noises and the airplane behaves like it should at low speed.  You get the mushyness, the stall horn (which is very good) and the sounds.  Good enough for me.

jeeze he was doing 60 degree turns, thats harsh, I know it depends on the AC but the most I ever really worked out in or had to do was 45, I'm sure its because of the plane..... I have ridden many many many times through stalls as my CFI was showing me proper procedure over and over again and then me doing it. The first few times I was doing the power off stalls, I was forgetting about carb heat and I wasn't looking at my ball ( big mistake in a stall ) so basically every time we would go up for a lesson we would go through it again and again, if I was doing them sloppy he would grab the controls and get me sharp again, you can definately feel the buffet more in a power on stall IMO, I've done so dang many of em I can almost predict when the nose will start to pitch over based on how many shakes there is, generally 3 right as it stalls, a little bump bump bump... Power on stalls were way easier for me to get the hang of in the begining, less procedure, basically just keep that ball centered and just release the pressure when it stalls... My main problem when learning that plane was doing 45 degree S turns and spot turning while keeping the  plane at the same alt, my CFI said it was because I'm used to flight sims and not actually looking at the real horizon and the surroundings, so I had to fly for a long time with the stupid inverted plastic thing on my head so I couldn't look at my instuments, that was the absolute toughest for me, but after a while I got the feel of when the plane is pitching or yawing.

Keep in mind that for a given rate of turn (say standard rate) your angle of bank is a function of speed.  The faster you go the steeper you need to bank.

To get the point home to students when they say "Steep turns! No way it's an outside visual reference maneuver!" I have them block my view of the instruments with a sexual chart and then I'll do my steep turns.  45º private pilot steep turns are cake and the view outside is always the same.  Here in Ohio we've got those fancy section lines that go N/S or E/W so you don't need any heading reference (just line up on a section line) and every time we roll out we get the bump of our wake.  It does make it difficult to cross check and I still go through the head motions (outside clearing ahead, scan the instruments, outside clearing ahead, scan, outside, scan etc etc...)

I am the uber 172 pilot :rolleyes:

Oh and if you're flying FS9 or any other flight sim...use the virtual cockpit.  Takes the instruments off of the "right smack in front of you" mode.

This video shows the angle...
