Capn kamikaze Posted August 20, 2018 Posted August 20, 2018 Has the harrier had a flight model change recently, it seems to like to go into an oscillation about the roll axis while in hovering flight now.
Nealius Posted August 20, 2018 Posted August 20, 2018 Something feels different to me as well, but on the pitch axis. As I come to a hover, I trim to put the Witch Hat on the horizon, then as soon as I change anything--roll input, nozzle angle--the nose goes up or down and I end up oscillating all over the place trying to retrim it.
Mech Posted August 22, 2018 Posted August 22, 2018 Not sure if the FM had changed...but just recently i started to feel the urge to add a slight curve to the throttle and i just managed a perfect VL. I just can't stop patting my own back.
Shrike88 Posted August 25, 2018 Posted August 25, 2018 (edited) +1 agree, not sure if the F-18 FM changes they added or ED augmented something to the entire DCS physics engine. With less laminar flow high AOA and flaps I notice much larger lateral oscillations than before. This is definitely more realistic as low speed and near critical AOA. As for the hovering it always seemed to be a little too "wobbly" in a hover and I thought the SAAHS is supposed to dampen and fix this. zero PIO noticed and appears very very stable. Edit: maybe I'm wrong. Just spoke with a good friend of mine in VMFA211, said hover was like balancing a marble on the Washington monument so maybe I'm wrong and it's very unstable.

Manzanita Posted August 28, 2018 Posted August 28, 2018 IDK about FM changes but this https://streamable.com/jn7uu happened to me and a friend recently for the first time ever. I'm going to say it has to do with the unrealistic asymmetrical behavior of the harrier and the recent FM changes.
Zeus67 Posted August 30, 2018 Posted August 30, 2018 We will check. "Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning." "The three most dangerous things in the world are a programmer with a soldering iron, a hardware type with a program patch and a user with an idea."
rinao0o Posted September 3, 2018 Posted September 3, 2018 (edited) This wobbling actually makes sense when you think of the physical mechanism the harrier uses to hover. When the harrier rolls during a hover it does so by blowing air through a duct on the wing tip. However the center of mass doesn't always align with the duct due to changes in payload and fuelload. And when it doesn't, any roll input will likely come with a pitching moment. Edited September 3, 2018 by rinao0o
