Unified numbering system

The UNS-1Ew and UNS-1Fw SBAS-FMSs provide a Performance (PERF) option for select aircraft types for which performance charts from the Airplane Flight Manual (AFM) are digitized and stored in memory. These FMSs will use pertinent data such as GW, ALT, OAT, etc., to provide exact values for V1, VR and V2, along with Takeoff N1.

Information is provided 'as is' and solely for informational purposes, not for trading purposes or advice. Autochoice operates its business from 18 locations located in the Canadian Atlantic region. You may also manually define a holding pattern by specifying the holding fix, inbound course, turn direction and either time or distance of holding leg. There are several methods that are used to measure the pitch diameter. The unique LIST function provides a quick and efficient means to access and enter data, minimizing alphanumeric entries and reducing input errors.

If the desired waypoint is on the flight plan, it may be selected by entering its list reference number. Vertical waypoints can be conveniently defined with altitudes or Flight Levels, and lateral offsets.

The message annunciator alerts you of system status advisories, including way- point alerts, sensor watchdog functions, TAWS alerts and self-test. The Message MSG key may also be used to access datalink communications should this optional equipment be installed. The navigation database includes holding patterns that are part of departure, arrival, approach and missed approach procedures.

The aircraft will fly the normal flight plan legs and then automatically enter the holding pattern upon reaching the holding fix. You may also manually define a holding pattern by specifying the holding fix, inbound course, turn direction and either time or distance of holding leg.

When armed, the holding pattern will be entered automatically upon reaching the fix. Once near your destination, you can easily link the appropriate approach for the active runway into your flight plan. Approaches and runways from the navigation database, and those which have been pilot defined, are easily accessed.

They feature the highest contrast, lowest reflection and greatest horizontal and vertical viewing angles available, and offer superb sunlight readability. Unique parallax control is also provided. The system uses two character sizes and line graphics to enhance data recognition.

Certified on Over 50 Aircraft Types Universal Avionics specializes in flight deck upgrades, providing flexible options for over 50 aircraft types, ranging from the Pilatus PC to the Boeing For example, the major diameter of a screw thread is 0.

The number series of machine screws has been extended downward to include 0. This defines a series of metric screws named after their major diameters in millimetres, from 0. Preferred sizes are 0. The thread form is slightly modified to increase the minor diameter, and thus the strength of screws and taps.

The number series of machine screws once included more odd numbers and went up to 16 or more. Standardization efforts in the late 19th and the early part of the 20th century reduced the range of sizes considerably.

Now, it is less common to see machine screws larger than 14, or odd number sizes other than 1, 3 and 5. Even though 14 and 16 screws are still available, they are not as common as sizes 0 through Sometimes "special" diameter and pitch combinations UNS are used, for example a 0.

UNS threads are rarely used for bolts, but rather on nuts, tapped holes, and threaded ODs. Because of this UNS taps are readily available. A screw thread gauging system comprises a list of screw thread characteristics that must be inspected to establish the dimensional acceptability of the screw threads on a threaded product and the gauge s which shall be used when inspecting those characteristics. This Standard provides essential specifications and dimensions for the gauges used on Unified inch screw threads UN [unified] and UNR [external threads only] thread form, and covers the specifications and dimensions for the thread gauges and measuring equipment listed in Tables 1 and 2.

The basic purpose and use of each gauge are also described. It establishes the criteria for screw thread acceptance when a gauging system is used. These standards provide essential specifications and dimensions for the gauges used on Unified inch screw threads UN, UNR, UNJ thread form on externally and internally threaded products.

It also covers the specifications and dimensions for the thread gauges and measuring equipment. It also establishes the criteria for screw thread acceptance when a gauging system is used. A classification system exists for ease of manufacture and interchangeability of fabricated threaded items. Most but certainly not all threaded items are made to a classification standard called the Unified Screw Thread Standard Series.

This system is analogous to the fits used with assembled parts. The letter suffix "A" or "B" denotes whether the threads are external or internal, respectively. Thread class refers to the acceptable range of pitch diameter for any given thread.
