(CNN) – With extremely cold temperatures gripping much the United States, travelers may be wondering how their planes are made safe for flying.

The short answer: Along with regular deicing of planes before take-off, airlines put their aircraft through rigorous testing in some of the coldest places on the planet before they are ever pressed into service.

CNN followed a team of Airbus engineers, mechanics and test pilots back in 2014. Their mission was to see how their test plane, a long-range A350 XWB, withstood extreme cold.

The Airbus team left the warmth and comfort of their Toulouse, France, base to perform various extreme-weather trials on the test plane in frigid Iqaluit, the capital of Canada’s eastern Arctic territory of Nunavut.

The ground and in-air tests included operating the A350 XWB in temperatures reaching down to -18 Fahrenheit (-28 degrees Celsius), thrust-reversed tests with snow and a local flight test.

From cold to hot

All new plane models must be tested

Shamburg Christian Church holds annual birthday dinner

“And the Lord said unto Moses … tell the people of Israel to go forward.” God had told Moses to lead the Israelites out of Egypt. After they had left, the pharaoh changed his mind. After all, the Israelites were their slaves — they did all of the hard work. He wanted them back and the Egyptians went after them. Camped by the sea, the Israelites saw them coming. They couldn’t go anywhere and they couldn’t fight the Egyptians. They thought all was lost. They forgot that the Lord was in charge and he was leading them.

First a cloud and darkness came between the Egyptians and the Israelites. Then the sea opened up and all those people walked on dry land between walls of water. The Israelites made it across safely. The Egyptians did not.

Often we want things to be a certain way

CRP Technology creates aircraft wind tunnel model with 3D printed exterior

CRP Technology, an Italian additive manufacturing materials company, has 3D printed multiple parts for a wind tunnel model of the tiltrotor AW609 aircraft. Using SLS and CRP Technology’s Windform carbon-composite materials allowed the model to be completed and tested within four days. The full 1:8.5 scale model prototype of the AW609 was made by Leonardo, an Italian manufacturer for the aerospace, defense and security industries.

Under the supervision of the Leonardo Helicopter Division (Leonardo HD), the AW609 wind tunnel model was designed, manufactured and assembled with a 3D printed nose and cockpit.

These, and other external components of the aircraft, were made with Windform carbon fibre reinforced composites. This material features high heat deflection and stiffness, thus, it is capable of withstanding the aerodynamic loads simulated during wind tunnel testing.

Testing aerodynamics in the wind tunnel

Wind tunnels are used to test models of proposed aircraft and engine components. The model is placed in a tunnel and air is blown past it. The forces on the model are then tested with various measuring instruments. 

The AW609 was tested at at Leonardo HD wind tunnel facility in Milan, using low wind speeds to assimilate a standard range of flight attitudes. According to CRP Technology, the tiltrotor AW609 model showed “excellent results”, with high-performing mechanical and aerodynamic properties.

In addition to aerospace, wind tunnel testing is also used in the automotive industry. Last year, Volkswagen tested its prototype electric

Is Kawasaki "Meguro" Trademark Hinting At New Model?

Is the “retro” trend in motorcycle aesthetic getting a little tired? While it seems like pretty much everyone has now found its vintage groove, inspired directly from their respective history, some companies aren’t done quite yet. Kawasaki, a bit of the late bloomer in terms of neo-retro models, having introduced the Z900RS last year and announced the W800 for this year. It looks like the brand might be on a roll, now, however. In fact, on January 23, it trademarked the name “Meguro”.

2019 Kawasaki W800 Café: Everything We Know
2019 Kawasaki Z400 ABS: Everything We Know

The Meguro Manufacturing Company got its start in 1924 as an engine manufacturer. After only a few years of activity, the company started dabbling in motorcycles, initially acting as a transmission supplier for a number of Japanese firms and manufacturers. The company came up with its very first bike in 1932, a 500cc built for Hamakura Motor and 5 years later, the Meguro motorcycle was born. Within 20 years or so, Meguro established itself as one of Japan’s biggest motorcycle manufacturer.

Where does Kawasaki fit in? Well, by the mid-50s, Kawasaki, then called Kawasaki Aircraft, had put a foot on the two-wheeler market with a scooter—planes and trains had gotten boring I guess. When the time came to graduate from scooters to small motorcycles, guess who Kawi turned to? You got it: Meguro. The

UNIVERSAL HELICOPTERS ANNOUNCE TECNAM FLEET ACQUISITION ACROSS THREE MODELS

TECNAM and Universal Helicopters (UHI) today announced an aircraft purchase agreement for a fleet of 10 initial aircraft for two fixed-wing flight training locations. The purchase consists of four (4) P2008 LSA, four (4) P2010 standard category 4 place, and two (2) P2006T twins. 

UHI has distinguished itself over the past decade as one of the largest FAA Part 141 Training Companies in the world, operating up to 58 helicopters for flight training and has its sights set on the Fixed-Wing training market. “As we watched the shortage of fixed wing pilots increase and the hiring requirements change, I felt compelled to assist the fixed wing industry as we have done for decades withregards to the helicopter industry” stated Dr. Gordon A Jiroux, hc.
 
Universal’s renewed push into fixed wing aircraft demanded a modern, cost-effective fleet for all training levels. Universal Fixed Wing (UFW) will be utilizing the high wing P2008 LSA for initial through IFR introduction training utilizing the Garmin G3X two screen system with Garmin autopilot and Garmin GTN 650. Students will then move to the FAA standard Category P2010 4 place single with G1000Nxi and GFC700 for completion of IFR, Commercial and CFI Certificates. Finally, students will fly the P2006T light twin with Garmin G1000Nxi to complete their Multi-Commercial and Multi-Instructor certificates. 
 
“The Tecnam line of aircraft that we chose as our primary training aircraft, offered the perfect progression of high wing Ab-initio trainers (P2008 P2010), culminating with their light Multi-Engine P2006 model” stated Dr. Jiroux.
 
Dr. Jiroux also stated, “Having

Boeing Issues Safety Warning After a Fatal 737 MAX Nosedive

Investigators are still working to discover exactly what went wrong with a Lion Air flight in Indonesia on Monday, October 29, when a Boeing 737 MAX plunged into the Java Sea, killing all 189 people onboard.

But the initial findings have highlighted a possible sensor problem, and that has been enough for Boeing to issue safety warnings to all the airlines that operate those planes, telling pilots to brush up on how to deal with confusing readings or erratic actions from the flight control computer, which could cause the planes to dive, hard. And now the FAA says it’s throwing its weight behind Boeing’s advisory, to make it mandatory for US airlines to comply.

In a statement, Boeing said, “The Indonesian National Transportation Safety Committee has indicated that Lion Air flight 610 experienced erroneous input from one of its AOA (Angle of Attack) sensors.”

An angle of attack sensor is what the plane’s computer and pilots use to figure out the amount of lift the wings are generating as they cut through the air. If the angle of attack is too steep, lift starts to decrease, eventually creating an aerodynamic stall, where there’s not enough upward lift to keep the plane aloft.

The way to counter that is to point the nose of the plane slightly downward, which safety systems will do automatically, as well as aggressively and loudly shaking the yoke control as a warning. But if the
