Charts & Plates

You dont have to know how sausage is made to enjoy it, but you might want to know about some of the ingredients. The same is true for instrument approaches. You dont need to know how they are made, but an understanding of the ingredients will help.

There is no question that pilots planning to fly IFR should always keep a current database in their approved GPS. Its not difficult and it demonstrates a professional attitude toward instrument flight and aircraft maintenance. In the perfect black and white world of flight schools and checkrides, this would be standard. However, in the real world of dumb luck and Murphys Law, this topic gets a little murky. …

If there was ever a high-performance document, the instrument approach procedure chart (plate) is it. Flying an approach asks a lot of us. Information needed for an IAP, SID or STAR must be retrievable quickly and correctly off the chart while minimizing head-down time away from the instruments.Until the mid-1990s, approach charts evolved without scientific study, driven instead by user feedback and flight safety. Liability proved a mixed blessing. Litigation motivates accuracy, but also makes…

I made up my mind to sell my house at that fancy Florida fly-in community the day a joker from the homeowners association scoffed at my Skyhawk and asked, You flew all the way from Chicago in that thing?

This past year weve delved rather deeply into many of the details and vagaries of approaches you can fly with your satellite-based navigator. To do so, weve used many industry-standard terms and their common acronyms. Since a lot of these are unfamiliar to many pilots, weve gotten criticized for our journey through the acronym jungle, as one reader put it. …

Its true. You really dont have the whole picture, by design. Alternate missed approach fixes have been sneaking onto approach charts for a while, but you wont easily find a way to use them. Its even difficult to find out when you would use those alternate holding patterns. [IMGCAP(1)] Those alternate missed approach holding fixes are associated with alternate missed approach procedures. These are in addition to your regular missed approach procedures and are established whenever the…

There werent any IMC Clubs when I began flying on instruments. I wish there had been. I might not have had to make quite as many mistakes for myself as I did. [IMGCAP(1)] Back in 1984, a designated examiner by the name of Francis Xavier Scott pontificated upon me and pronounced me fit to fly an airplane solely by reference to instruments. I clearly remember Scottys magic words: Lets go inside and get you written up. I…

In a pinch, you may only have access to one type of chart, and it might not be the type youre familiar with. A good briefing is essential for every departure and approach, and a good knowledge base for the chart type in use will help facilitate that briefing. Lets compare AeroNav and Jeppesen approach charts.Lets use the ILS or LOC Rwy 34 in Roanoke, Virginia for comparison. …

Reference Fred Simonds article Need Datalink? in the May 2014 issue. We first put datalink into our Bonanza about a dozen years ago after being stuck for a few extra days by weather. We had a post-mounted StratoCheetah by Echo Flight that used the Iridium satellite system. It worked reasonably well but was intrusive. Next a panel upgrade included the, then, UPSAT MX-20 with WSI datalink FIS. This is what we still use today in contrast to the XMWX system mentioned as the only available system in the article. There are some differences in the data and presentation, but the WSI receiver provides most of the same information as XM systems I have used.

Its no secret that general aviations accident rate is significantly worse than the airlines and corporate flight departments. According to NTSB studies over the first 10 years of this century, youre 12 times more likely to have an accident when flying your own or a rented GA aircraft.
