Boeing 247, your correct about not chasing the glide path and thinking about be at a steady approach attitude to intercept the ILS (localiser path and glide path or vertical and horizontal displays on the ILS gauge). The approach you posted is a little tricky but let me see if I can give you a simple explanation using the Capt Sim 727.

The ILS is 111.55 so you would set this on nav 1 and set your course indicator on the HSI to 260 degrees the ILS localiser course. As it is an ILS/DME you should get a DME readout from about 20 nm from the station or location of the Denver ILS for RWY 25. The 10,000 ft altitude shown on the plate is referenced to being at 14.8 DME (little box) and the altitude has a line underneath. The line underneath the altitude always means a 'not below altitude', you can be above 10,000 ft but never below to remain safe, so in this case you would not be below or be at 10,000ft intercepting the localiser at 14.8 DME. You would then fly in or track 260 degrees your vertical needle centred and be able to commence a descent to 8000 ft and not be below 8000 ft at that altitude until when and you do intercept the glide path (needle alive or starting to work wait until it centres on your HSI and then follow the glide path commands to continue descent on the ILS, noting again that you must not be below 7000 ft at 4.7 DME and then continue the descent to your minima on altimeter of 5552 ft or 200 ft which is the minimum height you can descend to in instrument conditions and if your not visual at that point then you go around following the published track which in this case is 260 keeping you over the runway as you climb out and your turn commences when you intercept the 306 radial from the Falcon VOR 116.3.

Looking at the chart and interpolating it would suggest the glide path will appear at about 8-10 DME or one third of the distance between 4.7 and 14.8 DME from the 111.55 Denver RWY 25 ILS.

Note that you can reference the location of the beginning of the ILS when you cross the 043 Radial of the Falcon VOR and the check height fix of 4.7 DME when you also cross the 002 Radial from the Falcon VOR and then use the same VOR to intercept the missed approach track which is the 336 radial of the Falcon VOR. This is for a localiser only no DME approach.

So here is how you would do it, you would have Denver ILS on NAV 1, HSI cursor set to 260 and Falcon VOR on NAV 2 and the indicator on the panel for NAV 2 set to the VOR setting and it will give you the picture with the needle pointing to the station and the tail of the needle moving up and the away as you cross the 043 R then the 002 R then the 306 R. You will get the standard glide path localiser indications and a dme readout in the dme counter window on the bottom left and the HSI.

So you would concentrate on the AI and HSI to fly the ILS, with a nice standard descent profile of say about 150 knots (about 750 FPM ROD)  noting the altitudes of not below 10,000 as you reach the Falcon 043R on the secondary nav display shown by the needle, the continue descending to 8000ft at which point you will get the glide path indicator begin to centre itself then continueing the descent following the glide path needle as a command instrument (fly up or down) to not below 7000 ft until you reach 4.7 DME and then continue on descending as your slowing to Vat say about 130 knots (only 650 fpm ROD) to the minima (NOTE: YOU SHOULD HAVE YOUR RAD ALT SET TO A 200 FT DH) then land or power up, gear up and then climb out as your retract the flaps if your going around.

The reason for the references to the RADIALS based on the Falcon VOR is that this is also a localiser approach and you could fly a localiser approach, that is there may be no glide path available and or your aircraft may not have DME by tracking 260 and then using the radial crossing points to positively fix your position and hence from the chart you would know your distance as for example if your on the 260 localiser and your crossing the 043 Falcon radial you can only be at 14.8 NM or the position shown on the chart. It is what is known as a positive fix or the intersection of two position lines.

As you can see they put a lot of information on these approach plates and some have a dual purpose.

If I could do videos I would put together a visual example for this approach using the Captain Sim 727 but of that process I am ignorant I am afraid.

Hope this helps you understand what is going on here for this one. As you can see it is one of the reasons in good crews and procedures you will review the approach and really study it well a good 10 minutes before the top of descent point you have it all squared away before you begin the approach and you know what your doing in advance. In two pilot crews the Pilot Flying will brief the approach verbally aloud to the pilot not flying and by doing this you cross check your understanding of what the approach involves how your going to fly it and what your going to do if it all goes pear shaped at the end.
