I recently purchased a Cessna 182 equipped with a 430W. There is a placard next to the unit that says "GPS for VFR use only". Other than updating the databases, is there anything else I need to do before this placard can be removed?
 
Certification and flight test by a qualified A&P. Contact your avionics guy.

Minimum will be a flight test; reasons why 430Ws are left VFR-only include having wrong coax to antenna, no GPS mode annunciator in pilot's view, etc.

Most likely, whoever bought it installed on the cheap.
 
Second that thought go to a good reputable avionics shop so he can certify the install.may have been owner installed.
 
Was it part of a flying club? I could be that it is an approved installation, but the owner placated it that way because the didn't want to bother updating it. I have seen that before. Best advice is to have an experienced/knowledgeable avionics guy take a look at the logs and installation and tell you what it needs to b legal.

To my knowledge the 430/530s do not require a seperate annunciator.

It depends where the unit is mounted. If it is behind the "pilot's field of view" which the FAA has established, then I believe a separate annunciator is required. AC 20-138 spells it out... +/- 15 percent up to +/- 35 percent horizontal.

The W versions do require a separate annunciator if they are placed too far from pilot's normal view (I've forgotten the spec - something like 11 inches). The non-W versions didn't require same.
 
IIRC, it's a proximity issue that's only in play when the unit and the primary flight display are more than ~11" apart or some such.

Most don't, but IIRC it depends on where they are placed in the panel, XX inches from the center, or line of sight. I don't think it would affect a typical 182 installation since the stack is so close to the flight instruments. But, best advice is to contact a good avionics shop.:D
 
Do we think we've told Duncan enough times that it depends on the location of the unit?

Hey, Duncan... Nevermind. ;)

When you look, 3 of us answered at the same time, great minds think alike, and fools seldom differ. :D
 
And all contained IIRC or similar language. Say again all after uhhhhhh?:D

It needs to be connected to a CDI such as GI-106A or equivalent. It needs to be connected to an encoding altimeter or barometric altitude source. As others have indicated, it may need an annunciator. Finally it needs an AFMS.
 
However,if he wants to fly it under IFR, he might need the newer cable and antenna, along with the flight certification by the FSDO. It's not just the annunciator.

I noticed, I just found it funny to read the reply line with one person after the other saying the same thing. :)
 
Come to think of it, I meant to answer, "let's ask John Collins."

And, no, I am not joking.
 
Why bother? His answer was just like ours--well kinda sorta. :p

Not updating the database is not a regulatory reason to apply such a placard.

I have seen that before.
I've never seen such a placard applied unless the installation really was not IFR certified.

Agreed.

The Garmin 430/530 Installation Manual has the details needed for those units.
