I have just bought a 1999 C182S with 5 partners. The plane is equipped with a King KLN89B (IFR Certified). Our group has a wide range of experience but 2 of us are Instrument Rated. We are debating the future of the 89B and I believe that the options can be boiled down to:
Keep the 89B, the IFR pilots will learn how to use it safely.
Replace the 89B with a 94. This is a pretty inexpensive option but some of our advisors are quite negative on the KLN94.
Replace the 89B with a Garmin 430. This is a more expensive option; some of our advisors say that is equipping the plane with the best mixture of capability and economy … others ask why you would change the GPS when the upgrade to the 94 is a pin compatible inline upgrade.
Replace the 89B with a 94 and buy a King Multi Function Display. Comparable in price to the Garmin 430, probably a better display than you get with the Garmin but again raises the question about which unit is actually better to use as an IFR navigation platform and subjectively by how much.
I’m hoping to hear from a cross section of pilots who can comment on this, I’ll bet that there is a lot of partisanship in our community about this so it should be fascinating to read your responses.
Thanks in advance,
