I'm sure it would have been more convenient and practical for John Alcock and Arthur Brown to have an INS system on board their Vickers Vimy and a pair of Garrett turboprops out on the wings instead of two WW1-vintage Rolls Royce Eagles; but they did not have all that, and this, among other reasons, and skill required to fly such a flight with what they had, is why their transatlantic flight was remarkable. Likewise, the skills required to drive a 737 around the sky without and FMC or INS, is why most people want a 737 of 1960s vintage, since they already have one with modern avionics.

Skill of navigation is just a part of flight operation, not everything. Beside letting VOR/DME takes most of my attentions during the descent I'd rather spend them on the energy management and perform a smooth descent.

 

The art of flying vintage won't disappear by just adding an INS or GPS. Just like adding a GPS or INS to those Russian aircraft. It won't take away the spirit, we can see them on tu154 and even Yak42. I have no idea why my words lead you to think of flying a FMC equipped add-on.

I did not write that navigation skill was everything, I've merely pointed out that it is a fundamental part of operating an airliner that is not equipped with automatic navigational waypoint sequencing, which it is. Also note that I wrote FMC or INS to differentiate the older and more modern types, since the older type INS is actually also flight management computer, albeit an early incarnation of one. If you want a 737 with more navigational equipment, the Classic and NG variants offer this kind of capability.

I was planning on adding the Civa INS to the plane when 1.0 is out. Those hdg bug control ways may cross my plans though, but she's isn't final yet.

Thanks CoolP, I know your modifications on 707 and 727, really appreciate.

I think we share that Concorde love too it seems. ^_^ You're welcome.

If you been watching CS over the years, you'd realize they are more historical with their releases of any model. They tend to model the first variants of each model they develop. For example the 757/767 doesn't have the speed tape PFD which came later. They come equipped with the old Egg Timer on the overhead that the original aircraft had. So it's not that unexpected at least to me, that more modern systems that came after introduction of the original model weren't included.

The CWS action of the autopilot (pitch) works BEAUTIFULLY to set pitch while climbing/descending, while the AP managed lateral guidance. This is often hard to replicate in FSX but this works exactly like the real function in the plane; engage AP, set lateral (Hdg in my case), gently push or pull the yoke to set pitch (CWS), until you reach altitude then set ALT HOLD. Superb!

 

Excuse my ignorance, what does CWS exactly stand for ?...

 

I have been trying to get the Pitch Command Control to work without any success sofar.( FD on HDG,Alt Hold Off ) Must say i am very surprised to read that, in order to set a pitch, you gently push or pull the Yoke ?.....

 

Can you elaborate a little bit on that ?

 

Thanks very much!

 

cheers,

CWS stands for Control Wheel Steering. Essentially it's a AP mode that you control with the yoke, (similar to Airbus FBW in normal law.) Your aircraft will maintain pitch or bank you set (Point to with the yoke). In practice it's rarely used, except in training scenarios.

Tom's absolutely right.

 

But on the Sperry 77 autopilot, on the 737-200 featured here, it is the only Autopilot mode available for pitch control (to climb or descend the aircraft) ; so it's used a lot!

Just to expand, I believe it (CWS) is used much more than us "airliner simmers" give credit for in the more modern 737 classics.

Ok, great ! Thanks ! Certainly new to me.. B)

So what about the Pitch CMD then ??..... It is explained ( more or less... ) in the manual so it should work, shouldn't it ? I am familiar with it from earlier 727/737 models in FS9 or even before. Always worked nice and easy.

The Captain Sim 737's CWS works perfectly for me, Jan. One of the more satisfying aircraft to "fly" with autopilot.

Can someone tell me why this topic is not in the Captain Sim forum like the Carenado topic was so quickly moved there yesterday?

Indeed. :Thinking:

It was completely the wrong decision to move that C90 topic out of the FSX Discussion forum and into the Carenado Support Forum yesterday; it was clearly a user-derived discussion about a new release; it was not a support matter.

 

It would be useful for us all, (to ensure that topics stay on course), if the moderator who moved that topic out, could let us know the reason for doing so.

 

I did send a PM to a Moderator yesterday, to request the 'move' be reviewed, but have not yet heard back.

 

If all topics that refer to a product get moved from the FSX Discussion thread, this section will become a ghost town.

I think you may be getting the 'Pitch' command of the (seperate) Flight Director system confused with the Autopilot servers. The Sperry AP on this 737-200 has no selectable pitch, via a control knob or dial; as said above, under AP control, the pitch of the aircraft must be set by the Pilot pushing or pulling the yoke, to set a given 'pitch rate'. The AP will then automatically trim the aircraft to maintain that pitch.

 

The FD has a 'pitch' knob that is used purely to set a reference pitch, for the pilot to follow on the FD bars. This is generally only used on Take-off with this AP.
