Pitot-Static Air Kits
SafeAir1 has a history of providing quality Pitot-Static Kits that make this time consuming and frustrating exercise a snap. Compared to conventional systems, SafeAir1 Air Kits save significant time during installation. In the end, you'll have a plumbing system that is more reliable, durable, and maintenance friendly than ever before possible. SafeAir1 Air Kits offer a great value, saving builders 35%, or more, over individual part pricing. SafeAir1 Air Kits are available exclusively through AveryTools.com
SafeAir1 "SkyView" Air Kit
For Experimental Aircraft ONLY. Applicability and suitability of this kit is the responsibility of the builder.
Introduction
Fittings in SafeAir1 Air Kits are of the Quick-Disconnect variety. The fittings capture the tubing with stainless steel retainers, similar to "Chinese Finger Cuffs". If you remember playing with these as a kid, you know the tubing is not coming out! However, by suppressing the release ring (around the tubing entry port on the fitting), the tubing is easily removed. Within just a few minutes, you'll be able to disconnect and reconnect tubing, in the blind, with just one hand! O-ring seals, and maintaining precise tubing diameter during the manufacturing process, ensures a reliable seal. This is a "game changer" when it comes to building, instrument installation/removal, and maintenance.
System Planning
Our schematics cover the three basic systems found in experimental aircraft today. Each Kit also includes fittings for some of the more popular options. Compare our schematic to your planned system. In most cases, our kit will contain everything you'll need to complete your Pitot-Static (and Angle of Attack) System. If you have unique requirements, additional fittings and tubing are available through AveryTools.com.
As for Air Kits, we offer three different "flavors". (shown below)
A. SkyView System (Or Similar) ADAHRS and Optional Back-Ups
Proper installation of the ADAHRS module(s) is critical. Primary Flight Display performance is significantly linked to a proper ADAHRS installation.
B. EFIS System with Optional Back-ups
C. Standard Instruments (Steam Gauge) and Encoder

Installation
Static Port Installation
The static pressure is obtained through static air port fittings. The fitting should be located where it can access the air flow in a relatively undisturbed area. This kit contains two fittings; one should be located on each side of the fuselage or in the location recommended by the manufacturer. With this positioning, an average pressure can be taken, which allows for more accurate readings in specific flight situations. Static air tubing is then routed forward to the various flight instruments.
Connection to Pitot/Angle of Attack Tube
The pitot and angle of attack pressure is obtained from the pitot tube. The pitot tube is most often mounted on the wing or front section of an aircraft, facing forward, where its opening is exposed to the relative wind. The image below shows how the Pitot line (green) and Angle of Attack line (blue) are connected to a Dynon Probe using components supplied in the appropriate Air Kit. Pitot and Angle of Attack tubing are then routed to the various flight instruments.
NOTE: If you're connecting to 1/4" aluminum leads, as opposed to the 3/16" leads found on the Dynon pitot, you'll need a 1/4" coupling assembly. These can be found at AveryTools.com and will replace the blue "AN" hardware shown above.
NPT Fitting Installation
Threaded fittings; (Example: Part No. 1, 2, and 3 shown in the lising above), swivel. In other words, after reaching the appropriate torque value, you can rotate the fitting and point the port(s) in the desired direction. You can also use this feature when installing a fitting in confined spaces. The port can stay stationary as the threaded base is rotated.
Snap Bushing Installation
Snap bushings in the PSA Kits require a 3/8" hole for installation.
Tubing Installation
Push the cut tubing into the fitting until you feel it "bottom out". It's easy to recognize. To remove the tubing from a fitting: push in (towards the fitting) on the gray colored ring where the tubing enters the fitting while simultaneously pulling the tubing out. Once you get the hang of it, it is easily accomplished with one hand. The fittings included in the kit are made for quick connect/disconnect. If you are frequently disconnecting tubing from the fittings, a light silicon lubricant may be used on the outside of the tubing as a lubricant. This helps preserve the integrity of the O-ring. (Water is also a suitable lubricant.)
NOTE: Minimum bend radius for Air Kit tubing = 1 inch

Additional Information
Durability is extreme and the ease of working with this product is second to none. SafeAir1 Air Kits have an operating temperature range of -40 degrees F to +200 degrees F. DO NOT allow MEK or Acetone to come in contact with any of the Pitot, Static or AoA system components.
