Garmin 530 waas
Went flying with a firend of mine who has this installed in his
aircraft. Question When we have the auopilot on with Nav mode clicked On the 530 we have GPS in the window, shouldn't the aitpilot follow the 530 Flight plan or direct to or approach selected course? Well it did not had to use Hdg mode in order to stear the plane Any ideas how it should work? I know when you are in VLOC mode that the Navs are are sending the signal for autpilot correct and GPS it is the 530 unit? Is this correct? |

This is correct unless you have either a digital autopilot or roll steering
installed in the plane. Otherwise, each course change needs to be entered by the heading bug (in heading mode), or the NAV pointer in nav mode on an HSI. |

The auto has a heading mode and Nav mode So even though the GPS is selected we actually have to steer it by heading mode? Auto won't follow the course on the GPS? |

Like the other poster said, the auto-pilot has to be capable of roll steering, rather than CDI steering. |

The exact response depends on the autopilot system Some digital autopilots
(I think like the KFC 225 or KAP 150) will respond to the course changes provided by the Garmin flight plan, do hold entries, etc. On the other hand, the analog systems (Like the KFC200) require either roll steering, or manual input of either the heading in heading mode (via the heading bug), or course input via the course indicator (in nav mode). I have an analog system, and am thinking about adding roll steering, which would be particularly useful in flying DME arcs and holds, etc, and especially in tracking the 90 degree turn in GPS approaches (which NAV mode doesn't do every well).

Roll steering is a method of control. It is built into the digital autopilot but it is still roll steering. Your analog autopilot has CDI steering. With the interface you will be adding roll steering. |

I know all that, but probably didn't express it very clearly. I'm just
trying to decide whether the 4-5k to install roll steering is worth the expense. Right now I'm facing replacing 10 switches at 200 each since Beech thinks there's something wrong with them, although they've worked fine for over 25 years. |

There most certainly *is* something wrong with those switches. They haven't produced any profit for Beech in over 25 years! Happy Flying! Scott Skylane |

Pilots here in Europe are wondering the same thing, since roll steering is being mandated for PRNAV. I wouldn't pay 4-5k USD for it, personally, not even here because there is no mandatory PRNAV airspace. However, if the USA goes the way Europe has, and starts bringing in lots of RNAV SIDs/STARs, then you will need roll steering because these are supposed to be flyable hands-off, AIUI. Roll steering will become important, if not essential, when RF legs become common on advanced RNAV instrument approach procedures. The procedures themselves will be in limited numbers, so they will be easily avoided. But, some of them will provide access that a TF to TF leg IAP can't. |

We added GPSS when we did a panel upgrade (mostly 430W) for our A36. GPSS is very worthwhile IMHO. For the first test flight we put in 2 waypoints and the AP (STEC 60/2) flew the 180 course reversal perfectly. It handles holds, procedure turns, you name it. An amazing box. |
