It's about FMC!
Never used it, and never had any problems in flight without it. Always found FMC a very boring stuff, a time waster to be honest. It prolongs pre-flight preparations by 10 minutes, argh.

Currently my fav planes are PA A320/321 and QW 757. From time to time I hop in PMDG 737NGX to feel it, but I prefer FPS easy planes like the first two from this sentence, until I get a better rig.

Never used FMC also in 737NGX, all I need is a flightplan, good ATC (PFE) and of course an autopilot. Just make a flightplan and listen to the ATC = perfect flight.

I understand that in RL pilots use them to insert flightplans with waypoints, SID and STARs, etc, but why I need it in FSX?

I know that bunch of simmers are using it because it is realistic approach, but beside that important aspect what else?

Realism

No pros using it in FSX, like, I don't know. lower fuel consuption?

because the FMC is the brains of the aircraft.

Lowering fuel consumption to a certain degree, sure. The FMC allows for precise vertical planning, which allows the airlines to save money on fuel by minimizing an aircraft's energy lost during those phases.

Mostly though, the FMC is used by pilots in FS because it's used by pilots in the real world. It allows for precise route planning, and changes can be effectively made quickly. If you want to switch from STAR A to STAR B for example, it only takes a few button presses, rather than going into your GPS and changing 5-25 approach fixes manually. That's beside all the other amazing stuff it does, engine out planning, fuel burn calculations, cost index management, the potential for RNP approaches, etc.

That's what I call a good explanation! Thanks buddy.

ROFL,  YES, any more than 2 minutes of pre-flight preparation must be a real waste of time if you are a Pro, and already know what you are doing.

 

Gotta get up in the and FLY !!!   Worry about getting down later   :rolleyes:

The FMC takes a huge bunch of the workload off the pilot. You can program the FMC in two minutes flat once you're up to speed. Apart from realism it adds the ability to see when you will arrive, helps with fuel planning, holding, en route winds, arrival and departure procedures and more.

How  do you insert a flight plan if you don't  insert it in the fmc, plus vnav also  takes info from fmc  as well

Glad to help.

In my SimCheck A300B4, I'm the brains of the aircraft. :wink:

The FMC is the heart of all airline flight operations;   not only navigation but weight, descent planning, performance, speeds, engine thrust control.

 

I honestly could not imagine anyone flying the NGX and not using the FMC...   Not to criticize in any way but I just couldn't imagine anyone would invest in that aircraft and fly it without using the FMC.

It's an entirely different category of simulation, and well worth mastering, as it gives you an appropriate way to fly a large, commercial airliner. Learning it is an education in flight planning and navigation.

 

I feel naked without one in my DC-9 Classic, but then that's a different kind of fun.

 

How  do you insert a flight plan if you don't  insert it in the fmc, plus vnav also  takes info from fmc  as well

I create a flightplan via FSX, and ATC will follow it. I'm also using default GPS panel to view how I'm doing.

 

But first of all, my fav plane right now is PA A320 v3 with some panel updates from official forum, and it doesn't come with proper FMC, that is the first reason. Second reason is, I don't have good rig for NGX or Airbus X Extended, lots of stutters, 15-20fps on approaches.

When I upgrade my rig to i5 or i7, then I will consider learning FMC.

 

The whole idea of FMC question that I posted here came from Frooglesim livestream last night. He was clicking on FMC buttons like 5-10 minutes, I was bored instantly, lol.

It takes less then 5 ,minutes when you are good at it and if you can load up your route
