![]() Bob Miller wrote: It sounds like you're assuming you need an IFR GPS for approaches. I'm suggesting using the GPS for backup xc navigation and using VOR/ADF/RNAV/DME/ILS approaches. Let's say you have an aircraft with a LORAN, a NAV/COM with glide slope receiver, and a marker beacon receiver. The radio stack is full, but you have a spare 3.5" hole in the panel. Would you - a. Replace the LORAN with an approach certified GPS. b. Add a NARCO 121 NAV in the round hole. c. Replace the intercom with an audio panel and MBR and replace the MBR with a NAV unit or slim NAV/COM. d. Something else. As always, money's tight, so I would pick b, though c also is attractive. Your choice?

b. Add a NARCO 121 NAV in the round hole. With Glideslope.
Get an autopilot to fit the hole. |

Good idea, but that still leaves me with the problem of handling approaches in which the FAF is the intersection of radials from two VORs. Any solution I can think of fills that hole with either a radio or a CDI. George Patterson If you want to know God's opinion of money, just look at the people he gives it to. |

Some of them have built-in CDI right on the front panel display. I don't find them very convenient, but they are legal. |

I thought you had to have a separate CDI to use one as a primary navigation tool for approaches. Is that incorrect?

My understanding (somebody please correct me if I'm wrong) is that some of the newer units (I'm thinking specifically of the CNX-80) are certified such that you don't need an external CDI, as long as the unit is mounted so that the built-in one is within some specified distance from the pilot's center of vision, or some such. |

As I understand it a "separate" CDI means one not shared by two navigation devices (radios). Having the built in display adheres to the separate requirement. I don't believe there is any requirement to use an external display. HTH. z |

I think that applies to the annunciator (msg, ptk) which is displayed in the lower-lefthand corner of the CNX-80. I don't think it applies to the CDI, but you could download the install guide from Garmin's site and find out. I looked into it once. Sadly my radio stack is too far from the centerline. -- Ben Jackson http://www.ben.com/ |
