HDI

Postby Juan Carlos » Sat May 03, 2003 1:23 am

Have you seen  the HDI when you are level? it looks like your 5 degrees ascending!!!

this is really  dangerous :-X

Can this gauge be fine tuned or fixed to avoid false readings?

;D

you are going slow, and also you need to pitch trim, it looks like you need some flight training, very handy to use it, you will learn lots..oh and its not HDI (Heading Display Indicator) its the Atitude Indicator you are thinking of.. :P and no its not dangerous..its normal for slow flight :)

No! i'm NOT in slow flight! >:(

Yes its ADI (sorry),  ;D

But   when i'm in LEVEL FLIGHT, the center dot of the airplane in the ADI DOES NOT COINCIDE with the artificial horizon! its always a bit up  like if it was telling I was climing.

And YEs its dangerous; Because if you where flying by instruments ONLY, no visibility and the ADI was not "calibrated".........well   you'll soon be six feet under the ground.... A little flight training would show you that.

I just hope you dont fly in this conditions or  you'r  flying  would'nt  last that long :'(

I've noticed this too. I just remember to keep it just a little above the horizon line. You can also use the VSI to see if your flying level. If the dot is slightly above the line and the VSI indicates no climb then your level. Otherwise the only fix would be to edit the panel and put in another instrument or you could edit the instrument it'self but that takes some programming.

It's like when shooting you either use a coars or fine bead. In FS2002 you keep a very coarse bead on the artificial horizon.

this VSI tells when you climb, but the ADI, the ADI shows what the planes attitude is to the horizon, just because its facing up it does not mean its climbing at all, and it should be because you are flying slow, or perhaps i may be wrong, it could be fs2002 but ohwell, good luck  ;D

The attitude indicator on the aircraft that i'm flying right now can be calibrated, but before each flight I make sure that it's set, which is easy cause i'm already level on the ground ;)

Its wierd....

      I know that the  ADI shows what the planes attitude  to the horizon is; not if your climbing or descending,  thats what the VSI is for.

    But, no matter what,  if you are straight and level  the dot on the ADI should coincide with the horizon line (I think so) . Unless ofcourse,  110 Knts and no flaps at cruise altitude on a cessna 172  is now called "Slow FLight" (than i really need more training  ;))

(besides I guess I'll knew it if I were in slow flight first of all )

  I  was just wondering if there was a patch or an easy way to edit the gauge, Cause I realized that this gauge was a bit inacurrate.

Thnks anyways for all your posts....Its very....educational!

The dot on the artificial horizon represents the nose of your aircraft in relation to the horizon.  If you are travelling at 70 knots with flaps down maintaining 2000ft altitude and course 045 degrees you are flying straight and level.  You may require between 5-10 degrees nose up to achieve this, thus the dot on the artificial horizon will point between five and ten degrees above the horizon line.  If you then wish to lose altitude you can drop your nose onto the horizon but you will gain some airspeed and your vertical speed indicator will deflect downwards.  You will not be flying straight and level at this point.

The artificial horizon, VSI, heading indiactor, turn co-ordinator, altimeter etc are all used together in instrument flying to determine the exact postion of your aircraft in the sky.  If you start trying to change what your instruments are telling you because you don't believe them you will soon crash.

Remember that it is possible to climb with the nose on the horizon and possible to descend in a nose up attitude.

Power + Attitude = Performance

Yes Yes  i agree! :D

Although this post is not about "striaght and level" flying   ::)

IF you look carefully on your "ADI" when you are at your designated cruise altitude and  cruise speed you will see the dot of the ADI  ABOVE the horizon line, wich I think its inacurrate. :P

the dot on the ADI being above the horizon line is not inacurate,
