Leading Edge: Engine Monitoring: Predicting the Future with Electronics

June 2014- Traditionally, a pilot has had one EGT gauge and one CHT gauge that he or she would use to keep track of the performance of an engine. The aircraft's manufacturer determined the probable location of the hottest running cylinder, placed a single probe there and then screwed an EGT probe into the exhaust pipe a few inches downstream from where the exhaust pipe joined the exhaust manifold. The theory was this: if you lean the engine by reference to what is normally the hottest cylinder and the exhaust temperature, you won't fry any of the cylinders or over-lean…

Garmin’s Passive ADS-B Solution

January 2014- Ever since the dawn of the Computer Age, two engineering factions have regularly engaged in trench warfare. One group believes that hardware-centric devices are inherently more stable solutions for an engineering problem, while the other group—the software-centric crowd— believes that its approach offers greater flexibility for less money. Garmin, arguably the best-known purveyor of aviation GPS devices, thinks that in the case of passive ADS-B devices, both approaches should be offered to the marketplace to allow the customer to choose which is best. Enter the GDL 39 Portable ADS-B Datalink—and its handmaidens, the Aera series of portable GPS…

Adventures with Bill – Avionics Bucket List, Part III

March 2012 The Revolution is Coming – Get Ready NextGen is going to cause an aviation revolution, and all pilots need to prepare for Jan. 1, 2020. If you are unfamiliar (or even if you aren’t), the JetWhine blog has an excellent discussion of the FAA’s proposed rule and its plans to decommission the majority of the VORs. (See Resources at the end of this article for the URL. —Ed.) ADS-B Out will be a requirement; GPS navigators will be an implicit requirement for decommissioning VORs. Every pilot will need to make a decision—and some may just give up flying…
