FBW Flight Control laws wrong ????

[GADGET]

Flight control feeling by default is more of a slow heavy aircraft than a fighter jet.

 

I suspect of FBW control laws to be messed up... the landing/flaps-down law seems to be used as normal-flight/combat law.

What do you mean?

The aircraft doesn't have any flaps.

I mean that FBW aircraft use different laws of flight regarding the phase of the flight

For instance A320 has 3 laws, NORMAL, ALTERNATE and DIRECT that include limitations on the flight envelope, protections for attitude and Gs, trimming, depending of the law, flaps settings, weight, attitude, altitude, speed, etc. The feeling of the aircraft is different for each law and pahse of flight. For instance, NORMAL law reverts to DIRECT law at 50 ft AGL for landing. I have flow the FBW A320 for 14 years and I know what I am talking about.

 

This M-2000 module feels as a flying truck in all phases of flight, not a jet fighter. It lacks agility and response on the controls... for me it feels as if the normal law included flaps deployment all the time, feeling more sluggish such is a landing situation.

 

Please consider that for the rest of the modules joystic curves need to be twicked somehow, about 10 in gain, to do the flight model less sensitive when flying formation or precision maneouvers... M2000 on the other hand is far too unsensitive already with curve gain zero.

 

Reach me on my email or PM if you want to talk about it.

I find that it works well with linear curves. I have to use logarithmic curves for most other aircraft in DCS. There are three sets of control laws I think. A-A, charges, and landing (active when gear down). It could be you have the switch set to charges all the time? It should be really agile once you put it in A-A mode. I really don't recognise your description of "slow heavy aircraft". What I'm seing on my end is probably the most agile fighter in the game. I can easily defeat anything (F-15, MiG-29, Su-27 etc.) in a guns only dogfight.

There's a G Limiter switch similar to CAT III and CAT II in the F-16 from BMS. It's located just around that missile selection panel, I believe to the lower left of it. The top is labeled "AA" for air to air, this is a law for more agility and supposedly after you've gotten rid of the drop tank. I have a feeling you're in the other config, which significantly hampers the amount of cool stuff you can do as a pilot because the plane won't let you rip off the drop tank/non-missile stores... Check that switch and report back! ;)

The concept of FBW laws is a bit tricky.

For example, being an unstable aircraft the M-2000 doesn't have such thing as a direct law: even in Ultime Secours (its "logical" equivalent) there is some computation done, and the gear position is used as a switch between a "return home" and "land home" modes for that last-resort setting.

 

Another "law" acception would be C* (that you surely know of: this is common on all Airbuses). For the general audience: basically any FBW Airbus will maintain constant 1g (flight path) in pitch, and in Normal & Alternate laws, stick movements = g demand.

 

On the M-2000, relaxed stick behaviour depends on AP, and stick movement = g demand is valid above 300kt.

At lesser speeds, the AoA becomes the main parameter, so that stick movement = AoA demand.

 

Having AoA as the main parameter is a mode that also exists on Airbuses, but only if you're doing something wrong (i.e. flying near stall AoA, a thing you should avoid, protections or not).

 

So, while there are similarities, I'm not sure you can fully transpose your Airbus knowledge into a M-2000.

 

Nevertheless, your main concern seems that you feel the M-2000 does not match your excpectations in terms of "sharpness" of flight controls. OK.

Did you fly a clean aircraft or a loaded one?

What was the position of the A/A-CHARGES switch?

At what speed(s) were you flying?

Almost 100% sure you are flying in "CHARGES" mode, OP.

Your system, your options, a track (would be the best)? Otherwise your report is simply irrelevant. I would also suspect you are flying in AG config...

Even in CHARGES mode M-2000 will roll 5 to 6 times faster than an Airbus...
