The View From Here piper flyer letters Jennifer Dellenbusch FLYING IN FOG The High and the Writey by Kevin Garrison, February 2019
Jen, When I read Kevin Garrison’s witty musings, it is with a smile on my face. His February column, however, reflected a more serious, altruistic side. Kudos to the astute aviator and author for proffering the perfect amalgam for earning an instrument rating. I especially loved the point he made referencing the cost of flight training, cars and braces for The 15th Annual the kids.

Ron’s response
I have done as you have suggested and have flown the aircraft with the angle of attack tab adjusted from one limit of adjustment to the other limit. I have only been able to get a little beep out of the stall warning system at extreme pitch angles in a deep stall. Would you happen to know if a person can bend or change the angle on the tab itself? I suspect that the tab may have Although the stall vanes on these two PA-28s differ, been bent in some previous life. neither tab is bent at a 90-degree angle.

However, in the past few years, due to traffic requirements, there are three optimum tracks that are spaced half a degree apart in latitude, or 30 nm separation between tracks.

Illustration: Scott Kinney Performance based navigation (PBN) With recent advances in technology, spe- cifically GPS, aircraft have never been more certain of their position in flight. With GPS’s increased precision, airspace can be used more efficiently, reducing fuel consumption, lowering carbon emissions and saving money and time. GPS is added to the list of sources FMCs reference and their addition virtually eliminates map shift for long-range operations (away from ground-based navaids). It is possible to identify a two-dimensional position (latitude/longitude) on With the added benefit of WAAS-capable the Earth’s surface when receiving accurate signals from three GPS satellites. GPS, safety is also improved on approach procedures with the introduction of LPV approaches (Localizer Performance with Vertical guidance). PBN is part of the FAA’s NextGen and Nav Canada’s “best equipped = best served” initiatives. GPS is, of course, amazing. And it uses time. At any given moment, at least four of the roughly 30 GPS satellites that are Illustration: Scott Kinney in orbit around the earth should be visible from any spot on Earth’s surface. Each satellite orbits the earth twice a day. It transmits its current position and precise time from its onboard atomic clock. The signal travels at the speed of light to your receiver, which notes the exact time of arrival of the signal. The receiver can calculate the distance from the satellite. This process is repeated until the data from three (2D) or four (3D) satellites is calculated and using a geometric process called “trilateration,” the position of the receiver is determined.

Clamp use…and misuse Moving on to the topic of clamps, proper use of the correct clamps to secure hoses, wires and ducting is one of the most fre- quent incorrectly-executed items I find when I look in a customer’s engine bay. Unquestionably, the most common mis- use of clamping devices is the use of tie Non-structural stainless wraps where a proper metal clamp should steel bolt, securing a baffle be used. (Tie wraps are also known as zip to a cylinder head. ties or cable ties. —Ed.) Tie wraps become brittle as they age and often break. Worse still, these clamps are made of high tensile strength plastic, that when exposed to vibration, can erode the soft aluminum that instrument, fuel and oil lines are made of. Tie wraps can also erode rubber hoses—ouch! One of my customers experienced an inadvertent in-flight test of the flame- retardant upholstery fabric we installed in his light twin. A loose tie wrap had finally eaten through a vibrating fuel pressure gauge line behind the instrument panel, resulting in an in-flight cabin fire. Bad stuff can happen in subtle ways. Non-structural stainless The proper way to prevent abrasion steel machine screws, holding between two hoses is to use aircraft-grade, two baffle sections together. rubber-lined Adel clamps secured with proper aircraft-grade hardware. Never secure a flexible duct hose to a flange with a tie wrap. For this job, I’m a big believer in using good-quality American-made screw clamps. Another clamping issue is that Piper used steel ratchet clamps on ducting. With time and rust, these clamps become Incorrect use of plastic tie unreliable. Send those bad boys to the wraps, intended to prevent landfill! Always check with your A&P for two hoses from rubbing guidance when substituting clamps. against one another.

Don’t be baffled by your baffles Now, it’s on to the biggie in the engine bay refurb process: baffles. Engine baffles and seals must be in good shape in order to direct all-important cooling air around and through the cylinder barrel, head fins and oil cooler to thoroughly cool these critical components. Over time, engine baffles take a beating A black line drawn with from exposure to vibration, heat, mainte- a marker helps identify nance events and, you guessed it, corrosion. a loose turbo system If you have an older, high-time airplane, it coupling hose. might be time to invest in an aftermarket FAA-approved baffle kit. Check the inter- net to source these well-made kits (or look below in Resources. —Ed.). Cracks as well as broken mounting holes and tabs are the most often-needed repairs when preparing reusable baffles for reinstallation. Let’s start with cracks. Begin with drilling a 1/8-inch diameter stop hole at the end of the crack, then fabricate an overlay scarf patch made of 2024-T3 aircraft aluminum of the same thickness as the existing baffle.

Locate the mounting holes at least twice the rivet shank’s diameter from the edge of the repair material. For example, 1/8-inch rivets should be set back 1/4 inch from the edge of the repair material and the center of the rivet. The rivets should be spaced approxi- mately 5/8 inch to 3/4 inch apart, mea- sured from the center of the rivets. These rivets are available in different lengths and for most baffles, rivets with an A cracked corner, unpulled shank length of 5/16 inch are repaired with rivets and correct.

Unplug the antenna lead coming from the transponder, plug it into the GDL 82, then plug a coaxial-cable jumper of the same gauge between the GDL 82 and the transponder antenna. Mount the antenna for the GPS receiv- er, connect to power and perform the setup process. That’s it. Since ADS-B data broadcasts through the transponder, the GDL 82 needs no separate UAT antenna. The package needs no separate control head. The GDL 82 detects the Mode C code coming from the transponder and broadcasts it as the aircraft identifier. ADS-B In is not part of the GDL 82 package.
