Jul 30, 2015 · Pitch trim on an aircraft with a stabilator is normally accomplished by moving the entire stabilator and holding it in its new trimmed position either mechanically (using the same mechanism as normal pitch control), aerodynamically (using an "anti-servo tab"), or some combination of the two.

Mar 22, 2020 · Nose heavy design, stabilator not in prop-flow (t-tail Seminole), etc. The stabilator on the Seminole is absolutely worthless below a certain airspeed for example. Then it’ll make the nose claw for the sky. Many call that “overly sensitive” but really it’s a result of it sitting on top of the T-tail completely out of any engine power ...

Jul 2, 2013 · My Cardinal RG had a stabilator, though, and it was FAR more pitch sensitive than all the other Cessnas I have flown. That was only a concern when landing, as I tended to over-control it. I was always a little more concerned with the inherent structural integrity of a stabilator than a fixed stabilizer with a smaller moveable surface, though.

Mar 5, 2017 · Its primary purpose is to allow the pilot to control a pitch movement with a less force (which I presume better serve big airplanes), and if so, wouldn't a horizontal stabilizer coupled with an elevator be a better choice for the manufacturers, especially given that a stabilator installed in small airplanes typically requires an antiservo tab ...

Dec 16, 2013 · When I look at the Piper stabilator linkage it always unnerves me that basically one small bolt is all that seems to attach to control rod. That attachment point is than placed on the trim tab and not on the main stabilator, as shown by moving the stabilator on preflight the trim tab will travel in the opposite direction.

Sep 22, 2015 · The stabilator design prevents this. Stealth. The stabilator design, with its clean lines and no discontinuities, offers more stealth compared to the stabilizer and elevator design. The design can also be optimised for stealth with edges etc. Some GA aircraft do use all moving tail planes for e.g. Piper Cherokee. However, there are a couple of ...

The 'static' position of the stabilator is set (stab range is 10 deg up to 45 deg down based on airspeed) to counter this pitch tendency. A right sideslip condition will result in a reduction of tail rotor vertical thrust resulting in a pitch up motion. The stabilator is programmed downward to counter the pitch up.

Feb 17, 2024 · The low AOA trim point (high speed) will be with the stabilator chord line somewhere closer to parallel with the main wing chord line, that is, minimal decalage. The high AOA trim point (low speed) will be with a significant decalage (to generate the maximum trimming down force to hold the nose up).

The stabilator provides an order of magnitude improvement in the flying qualities in forward flight. The MH-60 could probably be flown without the stabilator, however the pilot will need to re-learn flying the aircraft in a hurry. It will be very temperamental.

Apr 13, 2017 · $\begingroup$ Having flown an aircraft with an all-moving stabilator and no anti-servo tab, a more sensitive all-moving rudder is definitively not a pro, but a con. The rudder is a blunt force instrument to keep the airplane coordinated, and doesn't require the fine grained control of the elevator or aileron to maintain precise altitude and ...
