Canadian IFR equipment requirements

[petersb]

We need two methods of navigating, GPS and VOR.

Can this be included in one device ie: Garmin 430W and can the outputs be displayed on the same EFIS screen.

Because both devices are in the same box you could lose both GPS and VOR together, or if the EFIS display unit failed you would lose both nav outputs. I believe the 430 has a CFI and GPS display built in that could back up a display unit failure.

Of course a solution would be to have a 430 and and SL30 with its own head.

Anyway I am interested to know what the minimum that Transport Canada would accept

Hi Peter

As far as I know you do require two independent Nav system..IE: a 430 and an SL-30 ..a combined unit like a 430 alone won't do it..

It doesn't have to be a GPS and or a VOR...It could be a VOR and ADF if you like...

I'm going to get my RV-4 IFR certified in the spring so I will find out then...I have right now a SL-30 & a KLN-90B IFR GPS + a 796 as back up..

YMMV

CAR 605.18 (j)

"(j) sufficient radio navigation equipment to permit the pilot, in the event of the failure at any stage of the flight of any item of that equipment, including any associated flight instrument display,

(i) to proceed to the destination aerodrome or proceed to another aerodrome that is suitable for landing, and

(ii) where the aircraft is operated in IMC, to complete an instrument approach and, if necessary, conduct a missed approach procedure."

Which ends up meaning you need 2 completely independent systems. A single unit like the 430W won't do, because you have a single point of failure. I suspect 2 completely independent GPS's may not work either, on account that if the signal is the problem, you have a failure of the "system", though that would be asking a lot ... It's a rule that will eventually make less and less sense as other non GPSS navaids die off.

For now, a 430W or similar + an SL-30 or similar will do the trick.

You could inquire as to whether 2 entirely separate GPS's (i.e. 2 430W's for example) would make you compliant.

Yes the crazy thing is I could put in a WW2 ADF and VOR and be legal but not my Garmin 495, which is WAAS, and many times superior. Even my ipad running FlightPlanGo is superior, but not legal.

Using the 495 and Synthetic Approach on the HXr takes you down to FAF as if on rails.

My current panel has GRT HXr, Dynon D10A and Garmin 495.

The smart move would be a 430 and SL30 but with the Canadian Dollar tanking the already high price $US6000, for a fourth generation old 430W, is getting rather high.

Back when I built my -8, the dollar was around $0.63 US. Now that I am building a 4 seat Bearhawk, guess where the dollar is headed

Is there a cause and effect thing happening here? Maybe I should just stop building airplanes and that will save the Canadian economy

Yes, know what you mean. My 6 was built with an.62 cent dollar. Thought I scored when dollar was on a par when I built my 7A

[flyboy1963]

well, do we learn anything from this....... par-----tank-----par----tank thing?
well, I'm telling my wife, whenever it's near par, I HAVE to order a pickled I0-360, MT prop and an RV-14 kit.
It's just the responsible, Canajun thing to do eh?!

Stupid dollar, my RV-14 just became an RV-9 because of it ... not too big a deal, for my means, the 9 is the more responsible choice, but still ... darn ...

And I want to start building sooner than later, and who knows when it'll come back up ...

At least the tail is the most affordable kit ...

JF - you've seen our Glasair Sportsman project. It was bought mostly with a 70 cent dollar. I grumbled quite a bit about the bucks I could have saved by waiting for a dollar at par, but then I wouldn't have had nearly as much of the build completed had I delayed the start hoping for a better exchange rate. Sometimes we just have to take our lumps. I'm really glad a bunch of the avionics came in at, or near par. Gotta be thankful for the small things that do go in our favour.

Coming back to the original poster's question, yes, a pair of G430W's, or a 430W and a 430 would meet the requirement, as would a mix of 530, 430, 480 as long as you've got one WAAS navigator. The intent of the regulation is to ensure that we have diversity in nav signal sources and receivers as well as indicators so we don't get stuck in the soup without navigation capability as a result of a single point of failure.
