FMC\'s - do you use them?

100% correct Jaap. I can also turn VNAV off during cruise in those instances when the wind speed is high and shifting in direction.
BTW, have you ever got the Insufficient Fuel warning? I have never got it even when loading a low amount on purpose.

I've had that before, but only when I had unlimited fuel clicked on. I switched it off and it didn't do that anymore.

Thanks Dominic for the video tutorial link, it was very interesting, however I wonder how our freeware fleet would react to having a 3rd party FMC? For example most of the planes dont even have a VNAV/LNAV buttons, we will have to add them manually in the panel? Idk how this would work.. Id love to get some payware but at the moment im out of cash and my aging rig wouldnt handle them (too much detail on most, I even get performance drops using the Posky A330-300 from the freeware fleet)... so I guess for now Ill stick to the old flight planner and GPS =(

Ok Hector,I agree with that.Flying the B763 in the vnav mode while using PP can give you nice penalties ;)

Same problem with the Wilco Airbus, when starting descent its built-in VNAV aims for a high rate of descent, but there are fluctuations before it gest stabilized, which often results in vertical speeds temporarily above 5500fpm = PP penalty. Thus I always start descent earlier than the FP suggests, by controlling the vertical speed myself, until I am stabilized on the profile and only then I engage VNAV.

Sids and stars are imported from FSbuild if possible.

Normally I am not against writing the procedures myself for some frequently used airports, but it gets frustrating when you don't know which legs will be flown and which ones are completely ignored by the FMC.

So I end up by flying RNAV procedures with the FMC and flying by hand the navaid-based procedures.

No Hector,did not have the insufficient fuel warning yet.
Before flight I am using a fuel planner so after landing there will be approx. 25000 lbs of fuel left in the tanks.
This was a problem with flying the DC8.I could not find any figures about the fuelconsuming of this plane on the net.So I had to figure it out by flying some test flights.With succes I guess,because yesterday I made it from LPPT to GLRB without lack of fuel. :]

EHM-1749 Hector:
Hi Jaap, I normally use 15000 lbs for reserve, 15000 lbs for the first hour including climb, 12000 pph on cruise and 6000 for descent on the B763.
Regarding the DC8, I use 18000 lbs for reserve, 21000 lbs for the first hour including climb, 15000 pph on cruise and 6000 lbs for descent.
Those JT-A4 are fuel eaters and as a pilot said once: "those are engines that convert fuel  in noise".
With other DC8-30 I use largers amounts since the fuel scalar is 1.56 compared with 1.2 we have in EHM.
