Cirrus SR20

The Cirrus SR20 is an American piston-engine, four-or-five-seat, composite monoplane built by Cirrus Aircraft of Duluth, Minnesota.

The SR20 was the first production general aviation aircraft equipped with a parachute to lower the airplane safely to the ground after a loss of control, structural failure or mid-air collision. It was also the first manufactured aircraft with all-composite construction, flat-panel avionics and side-yoke flight controls.

Design and development

The SR20 was first flown on 21 March 1995.FAA certification was achieved on 23 October 1998. At the time of the airplane's release, the general aviation industry was struggling; the SR20 was the first of its kind to earn FAA Part 23 certification in several years. Over a thousand SR20s have been sold since deliveries began in 1999. As of June 2015, more than 6,000 Cirrus aircraft had been delivered, something that no other aviation company has done for decades.

One of the major selling points for the SR20 is its Cirrus Perspective avionics suite (by Garmin) with dual 10-inch (250 mm) or 12-inch (300 mm) screens: one primary flight display (PFD) and one multi-function display (MFD). This provides all standard communication, navigation (GPS and conventional VHF), and surveillance (Mode S transponder) functions. Other avionics features include in-flight weather information and TCAS-like traffic information.

Utah State Route 20

State Route 20 (SR-20) is a state highway in southern Utah, running 20.492 miles (32.979 km) in Iron and Garfield Counties, without directly serving or connecting any cities. It serves as a truck connection between I-15 and US-89 and an access to Bryce Canyon National Park. It may also be used to travel between Salt Lake City and Phoenix, Arizona. The highway follows the route of the Old Spanish Trail.

Route description

SR-20 begins at I-15, Exit 95, 14 miles (23 km) north of Paragonah, and heads east and southeast through a pass between the Markagunt Plateau and the Tushar Mountains. It ends at an intersection with US-89 at Bear Valley Junction. Trucks are routed from I-15 and US-89 onto SR-20 in preference to SR-9 and SR-14 to avoid steep grades and switchbacks required to cross the Markagunt Plateau. SR-20 itself is a difficult route, featuring 7% grades on the approaches to the 7,910-foot (2,410 m) summit, and oversize vehicles are required to have a pilot escort.

Alabama State Route 20

State Route 20 (SR-20) runs from the Tennessee state line (State Route 69) northwest of Florence, Alabama, east to I-65 east of Decatur in the northwestern Alabama. It crosses the Tennessee River at Florence (with US-43, US-72, SR-17, and SR-157) and also at Decatur (with US-31 and Alternate US-72)

Alternate US-72 follows Highway 20 from the Junction of US-72 at Muscle Shoals to I-65 east of Decatur, the entire stretch being four laned.

History

State Route 20 was created when Alabama renumbered State Route 41 with a statewide renumbering in 1929. The original route ran from US-72 at Muscle Shoals to US-31 at Decatur. This portion was named the Joe Wheeler Highway and markers commemorating this are still located on East (Decatur at ailroad/Church Streets) and West (Tuscumbia-Old Lee Highway) ends. In 1931, Highway 20 replaced State Route 2 following US-72 west to the Mississippi state line west of Margerum and in 1936 was extended east to Huntsville.

1957 saw many changes to SR-20. It was replaced again by SR-2 along US-72 to the Mississippi state line, and in turn SR-20 replaced SR-2 running north to Florence and northwest of Florence to the Tennessee state line (State Route 69), forming a route popularly known as New Savannah Highway. Highway 20 was also re-aligned to a much more direct route between Decatur and Huntsville, bypassing the town of Madison.
