VHF coverage Birdsville to Alice Springs
Anyone done this leg? Planning to make the trip from BN to Alice probably in July and wondering what to plan for..
Birdsville TREBL Alice looks good on the PCA, only a couple of very small gaps in the VHF coverage at 10,000 feet, but the direct route Birdsville Alice probably wouldn't be advisable, especially on an IFR plan.
Alternatively, I could take some oxygen and go up higher (wouldn't mind testing the actual service ceiling of the Archer, apparently my model can go up to 15,000..), anyone know the cost of a simple (pilot only) system and what coverage is like at 12,000 or 14,000? And yes I realise I might be stuck lower if the QNH is really low..
Cheers

PB, I have done Birdsville direct Alice in the Bo. At this time of year it should not be a problem to do as I did. Depart Birdsville on an IFR plan if that is your thing - downgrade to VFR and nominate a sartime for arrival Alice before you loose VHF comms - then when you are receiving Centre clearly inbound to Alice, upgrade back to IFR and cancel your sartime.
I would have been at A100 and would be very surprised if you can keep continuous two-way comms at that height.
Its a very lonely, but interesting, bit of country through there.

And heaven forbid, should the unthinkable happen, the overflying airliners will be on the Center freq (and 121.5). So keep the frequencies update to date as you go.

On an IFR plan your are required to maintain continuous communications - period. Quite often when VHF is marginal or there are gaps in the coverage I've done exactly what the FTDK did, and there's never been any problems.
BUT:
By using another aircraft to relay position reports i.e. one that's higher with VHF coverage or another aircraft in company with HF to relay for you, there's a possibility the nice folks at CASA will hit you with an ESIR (Electronic Safety Incident Report).

Did the downgrade/upgrade thing last month when crossing the Barkly Tableland enroute to Darwin. The "deaf" zone on that occassion was more than an hour.
No big deal if the weather allows for safe VFR.
I am reluctant to rely on overflying RPT to relay for me. If you can't raise someone, you will likely have some explaining to do.

Apologies for hijacking your thread PlankBlender.
PS: In Central Australia if you stay low Westbound and go high Eastbound you can generally get a tailwind both ways!

Hey Doc:
When you downgrade to VFR do you revert to VFR altitudes or is Centre happy for you to remain at IFR levels until you re-establish VHF contact?
The reason for my asking is that I'm planning a flight from BDV direct to AYE (IFR) in a VHF only aircraft and, like Plankbender, I anticipate being out of VHF coverage for a while and was wondering as to the best method of planning.

You are supposed to revert to VFR levels.

Birdsville to Ayers Rock direct - that would be an interesting leg!

Designated Remote Area????
PlankBlender,
Birdsville - AS might be through a designated remote area.
Not too sure about private flights, but with charter (even VFR), you need the HF on board.
Might be worth checking that out if you don't have a HF.

Soon after your departure report from Birdsville, Centre will advise you that you'll lose VHF comms at time zz, and won't regain them until Steel (reporting point). Simply downgrade to VFR (yes, obviously you'll have to change to a VFR altitude) nominate a sartime for steel, and then re-establish IFR at steel.
Dead simple.
BTW If you've got an ELT, no HF required. If you're doing a fair bit of outback work, you should consider hiring a satphone for Pilot Briefing and SARTIME contact. I hired one recently when the Chieftain's HF antenna downgraded itself to a clothesline. PM me if you want the details of a good satphone hire company I've recently used.
I reckon you're pretty brave donning the old oxygen mask. It's outside of my acceptible risk area!
