idle fuelflow and other small items

[fingertrouble]

Hello dear developers,

first of all you -again- did a great job. I love this bird.

But, here are my findings in first two flights.

I will not mention the windshield wipers and the start-up spooling times, I will not.

when I start in cold and dark the Nav1 frequency is misstuned to 101.09, with the first click it changes in the usual frequancy band, but initially this looks strange. The Xpdr is initially set to 7000, wouldn´t 2000 be more realistic?

Sometimes, in flight, some numbers are calculate so often, that they seem to change 5 times a second, e.g. Mach Number, TAS, wind, and sometimes TAT, is that real?

It seems that the documentation is not updatet yet, as it say April 2016 on every page. And contrary to that documentation I am missing several items on the ground service page like the loadsheet and the refueling.

The clock seems to be stuck in 1987, I gues this is an easteregg ;-)

The FMS has -again sometimes- difficulties in calculating times (ETA) especially on longer flights (I think I know this from the XP11 version) but i cannot replicate this on every flight.

The fuelflow in idle shows zero, on the ground after start-up and in descent. Oh no, idle on the ground, they show 0,03 t/h per engine, shouldn´t it be more 0,3 t/h? In descent they show 2 x 0,1 t/h?!. and shouldn´t it increase if I put engine anti-ice on?

If I turn the heading knob more than 180 deg in one direction the aircraft changes turn direction, is this normal?

Can you make the screw blelow the landing light switches a click-spot to retract all four landing lights at once?

I love that thing anyways,

fingertrouble.

Hi there, and thanks for the detailed feedback!

Some things are already known, you can always check that here:

https://forums.x-pilot.com/forums/topic/27194-ixeg-v15-for-x-plane-12-confirmed-bugs/

The Nav1 frequency will be "weird" in other X-Plane aircraft, too - I agree that it looks strange, but in subsequent use it will default to the previous frequency you had tuned during shutdown, so it should be a very transient problem.

The transponder code 7000 is for VFR flights in Germany, it is just an arbitrary choice. 2000 would be military night flying, 1200 is for VFR in the US.

Fluctuating numbers are measured very often, the pilot needs them to be updated all the time.

The documentation was not updated yet.

The clock´s year can not be changed (yet), that is a very low priority but maybe can be changed in the future.

The PROG page is still WIP, much of it´s content is not calculated correctly.

The fuel flow at idle is indeed a bug that will be fixed for the next version.

The effect of engine-anti-ice on fuel flow is negligible, we have not modeled it (just like the effect of winglets).

The plane will always turn the shortest way, if you turn the heading bug past 180 degrees, it will reverse the direction.

No, we won´t make a clickspot for all lights, but I might get Tom to make the inboard landing lights "toggle click" instead of "grab and pull".

Cheers, Jan

Is this a irl Classic quirk? It sounds quite dumb to reverse direction mid-turn.

Hey Jan! 
I agree with most of what you say here and the 180 degree opposite turn is true for sure. 
 

I would be inclined to disagree with what you say on anti ice and fuel flow, it definitely has a difference that’s noticeable on fuel flow in the Classic. I’ve noticed it over the years and it makes sense considering how much load is being put on the engines while bleeding for anti ice. The winglet difference is present too, I know it’s not something you would actively notice but it would be nice to know it’s as realistic as possible and choosing winglets will effect fuel usage. 
 

glad to see feedback is being listened to and issues rectified, hopefully it continues

Hi Jan, thank you for the fast answers.

For the blinking numbers, it is not that it should´t update quite often, as long as the value changes, e.g. the TAS when you accelerate, but when you cruise at a constant speed, the numbers seem quite nervous and change between two values.

Thank you for your great work, Bobby forever,

I will doublecheck that again, can´t say that I have noticed that yet. Maybe if you are right between two values... we don´t do any dampening, so if the temperature is -30.499 and then changes to 30.500 and goes right around those values...yeah, I can see that changing rapidly all the time?

Can you do a video of what you see?

Bobby is hobby, nur wer muss fliegt Bus ;-)

Hi Jan,

it was a bit hard to force it today, but when in cruise it sometimes happens. Mach Number and TAS, both are dancing from time to time, but I´m sure I saw wind, GS and TAT as well (but not today). Hope my video works.

 

My Progress page shows a wind even when on the ground not moving.

At the moment I fly without using any fuel, I had 8.6 t when I fired-up and have the same after 40 minutes in the air, fuelflow is indicated normal.

howdy

This is turbulence, try it without real weather and no turbulence.

I will try to see if I can reproduce the fuel problem!
