Coming soon: GCA for C-47V3

VFR, it was common to get a practice GCA from a "student under instruction and supervision". No problem, and usually tried to give them a complimentary debrief or humorous "OK, a little ragged but you're getting there" summary.

When I was going through basic rotary wing training in 2004 it wasn't unheard of for the instructor pilots to slow down to the hover during a GCA to see if the student ATC noticed. If they didn't some of them would reverse back up the glideslope.
 
Hiya,

Would be cool feature, in the Netherlands PAR approaches were very common for the military and civil tubelines landing on military fields. Only to be replaced by ILS installation 10 year ago or so (could the 15 years).

Example of a tubeliner doing a GCA/PAR approach:

My instrument instructor would take me down to MCAS El Toroin the early 70s to shoot GCAs as part of my training. Generally, they would accommodate us (i.e., civiliantypes), to give the military controllers some GCA practice. Flying 90 knots on approach didn’t always mixwell with F-4 traffic, but the controllers did a good job integratingeveryone. The air traffic controller wouldget you on final with simple vectors and altitude instructions and once youwere on final would hand you off to the GCA controller (I recall there was nofrequency change, but it was just you and the GCA controller—not sure how theyaccomplished that).

Azimuth commands were “Turn Right”, “Stop Turn” followed by “Turn Left”, “Stop Turn” and so on. Altitude commands on approach were “On glide path”,“Above glide path”, “Below glide path”, etc. Add to that an occasional distance update (“mile and a quarter totouchdown”). You were expected to execute the command—there was no read back. The last transmission was something like “Oncenterline, over the numbers” which was followed by a go-around since touchdownon military asphalt was strictly forbidden. I think MCAS El Toro discontinued the practiceby the mid/late 70s (I tried to run some of my own instrument students throughthe exercise but was denied).

I’ll be interested to see how much this ends upawakening some dusty memories.

This is really interesting! It'll bring a whole new dimension to anyone simulating the Airlift flying. Of course, it'll fit right in for much early propliner flying all over the place, too. Any details on how it will work? I'm just curious if it will only be available for certain hardcoded runways... or can it be made to work at any airport?

Great work... this will be cool!

as a Beta-tester i can say it will work at any airport.

I've been doing some beta testing so I can answer these questions.

Setup is easy. You simply drop a folder called panel.GCA into C-47V3 with the modern VC and select the proper panel.cfg for FSX or P3D which is included. (Banjoman and I have it working in C-47 with VVC (see video in original post), and he has it working in C-54, C-119, and others so it is adaptable to other aircraft with some fiddling.)

What you get with the new panel is the amazing AILA gauge that provides all kinds of functions that Manfred has adapted (with permission) to provide an Approach Control and GCA for any runway...actually any spot you want to call the runway end, which will give helo drivers a GCA capability for North Sea platforms or wherever. (I've tried it on a stationary aircraft carrier and it worked fine. Still pondering how to make it work on a moving one so the vNavy folks can also have CCA capabilities. No clue what happens in a sim if a helo backs up the glideslope as, I'm told, has happened in real life.)

So to use the Approach Control and GCA capabilities you open the AILA panel (Shift -6) and select an airport and runway, set an intercept point (typically 8nm for a 3.0º glideslope), and then click a button to engage the Approach Controller function. A sweet voice on the radio says, "This is Approach Control. Standby for vectors to runway XXX." Then she warns you about terrain clearance and gives you headings to the GCA intercept where she turns you over to the GCA Controller who talks you down. (You can skip the Approach Control part and simply fly to about a 10 miles straight-in and contract GCA directly.)

There are some geometry issue which may cause Approach to redirect you. For example, she really doesn't like it when you arrive beak to beak with departing aircraft, flying down the departure corridor. And you need to be outside 15nm on initial call so she can vector you into the GCA box pattern and get you turned in toward the GCA glideslope intercept point, all tidy like.

One important point to keep in mind: so far she can't provide terrain and obstacle clearance, that's your responsibility. Where available I use VOR/LOC/ILS/GPS approach plates to get Minimum Safe Altitude (MSA) info and use that until on the final approach course. You can also get obstacle clearance numbers off Sectionals and enroute charts. I use SKyVector.com.

Anyway, once you or Approach have you somewhere near the PAR glideslope intercept point, typically 8 miles and about 2500' AGL, the GCA controller will give you heading and decent advice down to about the threshold. What you'll hear is "You're well left, you're left,you're on centerline, you're' right, you're well right" and "You're well below, you're below, you're on glideslope, you're above, you're well above" about every 4 seconds, as appropriate.

But if you're precise you'll hear, "On glideslope, on centerline, " a phrase that has passed into aviation history. But not if you fly FSX or P3D.

The Big Lift about the Berlin Airlift features authentic, GCA, C-54s, and DC-3s (with some footage missing and lots post-war propaganda). Available free at https://archive.org/details/The_Big_Lift#
Strategic Air Command with Jimmy Stewart and Airport have GCA sequences, as mentioned earlier in this thread.
Flight Command [FONT=Verdana, Arial, Helvetica, sans-serif](1940) available from Amazon streaming for $3 is good but typically schmaltzy WW2 flick about the development of GCA.[/FONT]

Is it just me or is editing a post impossible? When I click "Edit Post" I get a blank text box, with nothing to edit. Happens in Safari and Chrome. [Update] I was able to edit this short post. Must be related to length.

Anyway, here's an important edit: What you'll hear is a heading assignment such as, "Turn right heading 039," or "Turn left 310," and You're well left, you're left, you're on centerline, you're' right, you're well right" and "You're well below, you're below, you're on glideslope, you're above, you're well above" about every 4 seconds, as appropriate. You'll also get some hints such as "check gear down."
 
I am looking forward to this. Not since the Aviano Air Base for FS9 payware by Cloud9 has there been any sort of GCA functionality in flight simulator. You know an airport's equipment needs calibration when you hear - on course on glide slope all the way on final to a PAR and your instructor tears your hood off and asks you if you think you can make the landing because you are about 20 feet right of the right edge of the runway.
