Help with 737 visual approach

Recommended Posts

I need some help with visual approach using PMDG 737. I always use ILS autolanding so I have no knowledge about manual landing. In some airports like Skiathos, there is no ILS so I have to land it manually. I programmed the FMC till the runways with NDB approach. It descends until 2000 feet but doesn't line up with runway. LNAV finishes around 10nm to the runway so I had to manually turn the plane aligning the plane and descend manually. Can someone explain the steps for it? Thanks

If you do not understand how to actually fly an airplane, I'd suggest doing the tutorials with the default cessna first, and reading various tutorials about the basics of flying online.

Ignore the advice given above. That kid obviously has attitude. When I get home I will step in with some advice if its not already been given.

Some VOR stations are not ligned up with the runway. You could try an RNAV approach so at least you have the majenta triangle to help you with your descent

 

On the EFIS turn on FPV and keep it pegged at a -3 degree glide slope.

DIsagree....

 

If he does not know how to turn the plane manually or descend manually he should take a few steps backwards.

 

Hand flying the 737 is the same principle as any aircraft, so learn how to hand fly an ILS approach in a Cessna, then in something like a Lancair, a Twin and then the 737.

I'm on Tapatalk, so missed the forum header. Is this the PMDG forum by any chance? It certainly feels like it.

Are you trying to do a visual approach or an instrument approach?

 

If you're doing a visual then from what I understand you're not supposed to use the instruments (ILS, VOR, NDB, etc.) but rather follow a visual traffic pattern keeping the airfield and runway in sight going from downwind leg, to base leg, then turning to the final leg and descend towards the runway at your VAPP speed, landing config with flaps and gear down etc. You'd normally descend at around 700-900fpm, a good tip is to use the PAPI lights on the side of the runway during your approach as they help to keep you on the glide path. 2 white lights and 2 red lights mean your on the path, more red means you're too low and more white means you're too high. There's a whole section on doing visual approaches in the FCTM that comes with the NGX that I'd recommend that you read as it will explain all techniques in more detail.

 

As for non-precision instrument approaches (not ILS) including VOR, NDB and RNAV, I would also recommend reading the chapter on 'Non-precision Approaches' also in the FCTM. I usually do VOR approaches at airports that don't have ILS as the next choice, the basic principle is to tune into the airport's VOR station before the approach and set the inbound radial using the CRS knob on the MCP, as your begin to approach the final approach course you can arm LOC mode by pressing the LOC button on the MCP as that will capture the VOR radial that's been set. There's no vertical guidance or 'glide slope' as it's only a VOR so you will need to monitor the DME on the ND during your approach, refer to the airport VOR approach chart as it will contain the altitude steps and DME from the VOR for guidance as you descend. To make it a bit easier, you can use VNAV for this and it will follow the vertical profile in the FMC if you've selected VOR approach. Also make sure to set the MDA (minimum descent altitude) using BARO on the minimums knob as this will be the point at which you decide to continue and land or go around and do it again, by this point I normally always have the autopilot and autothrottle disengaged and land the plane manually.

 

Keep in mind that though that the aircraft will NOT automatically descend when you reach the IAF (initial approach fix) and will need to set a next lower altitude for it to continue (also refer to the airport's VOR approach chart for this).

 

As mentioned above, some VOR approaches don't always line you up with the runway so you will need to disconnect the automatics and take over manually when see the runway then line yourself up. From here on it becomes a visual approach.

 

The RNAV approach is also another good option as it will follow the FMC vertical profile using VNAV, you can also use LNAV as you don't track a VOR radial or localiser. You'll still need to monitor descent as it's also a non-precision approach and make sure to set the next lower altitude down to MDA. The good thing about the RNAV approaches is that you can use the IAN feature of the NGX and arm the APP button on the MCP before final approach. This will effectively turn your approach into an 'ILS-like' approach providing you with vertical and lateral guidance 'dots' on the PFD, all data is still provided by the FMC.

Don't want to add fuel to the fire, but in the NGX documantation you'll find procedures and techniques to manually land the 737. It's much easier to add or stress a few details via this thread than posting lengthy instructions - just my 2 cents ...

If you are going to use the NGX, forget the cessna and learn the procedure in the NGX!

 

THe OP clearly can fly the NGX, just with instruments and not using visual procredures. Follow the good advice above from Michael and you'll be nailing these in no time.

If entering some figures into the FMC, press some switches on the MCP and let the AP control the AC from take-off to touch-down is considered flying, then you're obviously right.

But I think for flying an airliner one should at least know how to read the approach charts in order to get a basic knowledge about what to do. I admit that I like the AP flying the complete procedure until 1000ft AGL, but I always go over the approach and think about what I'd have to do, just in case... And for this purpose the Cessna seems a better choice to me, because it's slower, giving you more time to prepare for the next steps. Besides, all it takes to do that is to complete a few of the FSX flying lessons, or at least read through the instructions.

Other than that, I think what Michael posted above is a good advice, in case the OP doesn't want to learn something new he could apply to any aircraft.

Sorry, no offence intended, but, honestly, ... what's flying without landing?!?

 

I understand how to fly it but I don't know how to land without autopilot.

Why not just disconnect the autopilot completely and hand fly the aircraft towards the runway?

The problem is with your original statement. It gives the impression to many that you do not know how to land an aircraft in the simulator, whatever the plane may be.

Before you even attempt the levels of automation that Autoland, autothrust and so on offer, you should know how the plane handles, be it at low speed, with or without flaps, gear up, gear down, and so on. Perhaps you should complete the tutorial flights that are supplied with the aircraft.

 

If you have no idea as to how the aircraft handles in the simulation when handflying and controlling the thrust manually, then it is going to be difficult for anyone to provide much help. Potential helpers need to understand what your knowledge of flying in the sim actually is, before they can start talking you through procedural stuff...

 

Perhaps you should clarify your situation and knowledge a little more...

 

It appears you have tried to run a long time before you even attempt to walk.

I see some nasty pathetic 14 year old wannabes who believe they know it all, but don't. They lack the knowall and goodwill to offer true advice, preferring rather to try and gain some sort of childish and pathetic "one up manship" in order to make themselves feel better in their own self serving "belief" that they can fly an aircraft on their computer.

 

Bring back the good old days when enthusiasts wanted to help each other rather than go out of their way to put each other down. It is that first reply that has finally convinced me that this hobby is going downhill and I really do miss the good old fs days when kids were not allowed near their dads compuserve connection.

 

Banned probably now ... but who gives a monkeys when you see such a childish reply to a sensible OP question. Rant off.

Agreed.

 

I too remember those days. Oh they seem so long ago.

 

Now it's certainly ego driven with a dash of impatience.

Hahaha. As my wife just said (and she is only 43) "In those days, Compuserve was so expensive for international connections, it kept the riff raff away". Cheeky ###### .... or is she?

 

Hahaha. My humour has returned, but there again some cultures dont understand humour. God I miss the old days !

What's wrong with the first reply? He wasn't being rude or anything, he genuinely thought that OP meant he only knows how to do landings with autopilot and doesn't know how to hand fly the aircraft, and in that case practicing hand flying is the only solution.

 

Original post doesn't really explain what's his problem with doing visual approach so it's easy to misunderstand it and think that OP simply has never learned to land the aircraft without help of autopilot.

I understand how to fly it but I don't know how to land without autopilot.

 

See also this post, it doesn't explain if OP doesn't know how to control the aircraft without autopilot or if he simply doesn't know how to do a visual approach with real world procedures, I guess OP meant the latter.

 

 

I think the only childish replies in this thread were made by ANZ121 and Hirdy2013, spreading hate when those who replied simply didn't get what OP meant with having a problem doing a visual approach.

 

 

If someone has always done all the landings with autopilot and then asks how to do a visual landing with manual control it's perfectly appropriate to tell that person to practice manual flying, that's the only way one can learn landing manually. Apparently in case of OP manual flying wasn't the problem but procedures related to real world style visual approach or something...

No worries. Just wanna help out a fellow simmer  :smile:

 

Don't worry about some of the others, you're asking for advice so they shouldn't shoot you down like that. If you're turning off the autopilot 10nm from the runway and hand-flying the plane to land then that's kinda the basic principle of a visual approach. I used to do the same when I was still learning, even before I got the NGX and still flying the default 737NG.

 

If you've done the first tutorial flight it will only teach you the basic procedures including ILS approach with autoland, which is still good as you'll actually know how to fly the plane on a basic level. I'd also recommend doing the second tutorial which involves a rather complex approach in LOWI where you'll have to track a localiser down to a certain point then do a circle-to-land visual approach. Quite challenging, but if you follow it precisely you'll learn a lot from it.

 

All this talk makes me wanna fly the NGX now!
