Interesting - no mention of CTL on the Jepp and quite different procedure altitudes. Anyone know what "LR-101" is on the Indi chart?

They're same = 2250.

Well - never come across 'LR' before in all my years. My point about proc alts was that it is extremely difficult to know when to descend to 2250 on the 'native' chart ie is it when established from the arc or when passing the 101??
Like OK I would not like to try and brief from that chart - and I think I'd hold 2600 until established.

Lead radials are fairly common here, esp at military fields.

OK465

What's missing in the DEL chart is about 20 planes with 20 different languages and a very busy controller all at high volume trying to get clearances for that mess.

WRT TOL, doing a 10 DME arc in a C-model must have been fun, at least it was over in hurry. Darwinian, indeed.

g.f.:

180 KIAS?

Had to be the later C with the VOR/ILS/TACAN. The early version only had an ADF ("birddog" in USAF-speak)

I don't think there was an auto-pilot until the D model (?)

aterpster,

I only flew Ds and in the ANG we had ILS, but the Cs did get upgraded at some point. Yes, 180-ish, maybe 185. If the D had an autopilot it was hidden from me.

Did you fly the Hun?

Actually in the early 70s I believe neither the C or D had ILS, only TACAN & ADF, ADF of course used primarily for music.

In fact IIRC the Fs at TUS were upgraded with ILS first....you could do an ILS on your instrument check before going back to your TACAN/ADF only single-seater. Ds ILS came later, not sure about the Cs, although Niagara & Des Moines had Cs for a long time.

The only thing I remember in the C/D/F was a yaw damper, don't recall an auto-pilot, but it's been a looonnnggg time ago. :)

edit: BTW they put the ILS in the Guard C(?), D & Fs because most of the ANG units were at civvy airfields with ILS.

- yes, I'm quite happy with them it is just I have never seen 'LR' on a chart - maybe I'm too sheltered, Mil, Aerad and Jepps:)

g.f.:

No. I was USAF enlisted right out of high school when there still was a draft.

I was trained as a radar gun sight tech on the F-86F, then the same equipment went into the F-100. The last year I was on active I got transferred to the F-100C simulator (the early version). I had my private ticket by that time so the OIC let me fly it every morning to "preflight" it. We also had a couple of C-11 trainers with all the nav gear the later C had. I few those a lot too. Really helped with the instrument rating a couple of years later after I got out and went to college.

Sheltered indeed! Been on our AIP charts for a couple of decades here.

Even more shocking... there's an "LB" on that chart Agent 86 linked to in post 4! :}

Then again, we've had Distance/Altitude profiles on our charts for about the same time, with the rest of you only now catching up. :E

Again Captain B, another notation I have not seen on charts in my sheltered life. I've only been aware of the Jepp style info. Out of interest, which AIP are you referring to? PM if you wish.

See post 4. Jepp charts here have the lead bearing/radial depicted but not the letters "LB" or "LR".

++ padding

lydd airport, EGMD in UK has dme arc for the NDB and ILS. Also offset. Quite interesting with the power station and the VOR close by, is not used by the airport.

BOAC the UK AIP has lead radials in its native charts as well.

They call them though Aerodrome Influencing of traffic patterns for a procedural aerodrome or of landmark value.

I'm afraid I did not undertsand your second paragraph, but in (1) you are saying that the UK AIP annotates the letters "LR" on the charts, I understand?

No it gives the radial and a slash across the dme arc just like the others with the radial.

It just has the long winded rubbish that I gave, to describe what it is in the chart symbol key.

ie the point at which you can then turn for the intercept.

I have heard it been called numerous things over the years.

release point, lead radial, intercept point, lead bearing... but the UK AIP has definitely come up with the most unintelligible description by a long shot.

The Lead Bearings are the QDMs on this chart:

They are the same on them all now as the EU plates have been all standardised in the AIP's and centrally kept.

You just get that perpendicular tick across the arc.
