VOR nav to IAF (non-GPS)?

Hello! I have a basic IFR question when flying with a non-glass plane like a C152. My flight plan is from KPTK to KFNT, a very short simple flight in the metro Detroit area. I typically tune in the FNT VOR and am eventually cleared to the ILS 27 approach via the HARRO transition, at which point it tells me I’m cleared to HARRO. Approach information is here: https://skyvector.com/files/tpp/2112/pdf/00618IL27.PDF

My main question is how do I navigate to HARRO from wherever I am in the flight? Assuming I’m somewhere SE of KFNT, do I stay tuned to the FNT VOR on the 274 radial and when I cross that radial turn right (E) until I hit 10 miles on DME and then execute the PT? Or is there some other way I should be doing this? I appreciate the help!!

With my limited knowledge, I would say, if you are in a C152 without GPS, you are not equipped to navigate to a fix, and ATC “should now that” as when you filed your FP, you informed them that you were not GPS equipped.

Their clearance should not have been “cleared to the ILS 27 approach via the HARRO transition”

Instead it shoudl have been “You are xx miles from Harro, fly heading 320 to intercept the localizer, maintain 3000 till established, cleared ILS approach 27, Bishop”

ATC should be vectoring you to Harro, (IAF) on a 30 degree or less intercept to the ILS.

Thank you for those thoughts! So in a sense, because FS2020 doesn’t really do vectors right now, it’s kind of “broken” to suggest that transition? I should note that I’m using the stock ATC…
Thank you again, I really appreciate it!

The approach plate says that DME or RADAR is required for the procedure entry. You would either be vectored to HARRO by ATC, or you would fly outbound on the FNT 094 radial until 10 DME (which defines HARRO) then enter the holding pattern. You would tune your Nav receiver to the ILS localizer when entering the hold, turn 30 degrees left to a heading of 064 degrees, fly outbound for 1 minute than execute a standard rate turn to the right until intercepting the localizer. You would need to keep the DME tuned to FNT VOR so you know when you are crossing HARRO again inbound.

Thank you! So the case I described is roughly correct where I would fly up to the 094 radial, execute the hold PT at 10 DME, and go from there, correct?
Thank you!

Yes, that’s exactly how you would do it if ATC vectors are not available.

I agree with @N6722C’s reply. But there is a twist. If you look at the approach chart there is an * after the Great Lakes App Con and Flint Tower frequencies. That means they are not in continuous operation. That means that depending on when you are flying, you may need to fly the approach as published. MSFS doesn’t take that into account, so that is kind of a moot point. But in the real world, if you had to fly the published approach, you would fly direct to the FNT VOR, turn to intercept the ILS outbound and at 10 DME fly the holding pattern entry in lieu of a procedure turn. From a practical point of view, they end up being the same thing. At 10 DME you would turn left to a heading of 064, fly outbound for one minute then turn right to a heading of 244, intercept the localizer and fly it inbound.

There is yet another MSFS twist !!

You can, in MSFS, request Vectors to next WP, from ATC

but

In many cases, that Vector is completely INCORRECT, and the heading given is NOT from your current position, so is totally useless !!

SO, use this feature with care !!! It’s badly broken …
