![]() No doubt any update is a good update and again this is a good one, the greenish texture colour is debatable but far better than the ghastly yellow hues. The v1.8 update covers all versions including the Professional and Extended packages. The excellent 777-200F comes with a huge side loading cargo door, great for all the haulers. Now one of the most common B777 version with 721 ordered and only 250 aircraft left to be delivered, you will see plenty of these at your major local hub. The B777-300ER is a 33ft stretch over the standard Boeing 777. The -200ER is significant because the Pratt&Whitney PW4090 engines are noticeably smaller than those giant GE90-115B turbofans on the -200LR. I will just re-note the packages in the Boeing 777 Series.īoeing 777-200 LR - (Boeing Worldliner Professional)īoeing 777-200 ER - (Extended Pack - With PW4090 engines) FlightFactor/VMax have been very good in the updates and keeping the aircraft as one of the best for deep simulation and incredible systems that give you a real understanding and feel of what the Boeing 777 is as an aircraft. There is no doubt the Boeing 777 philosophy in this being a great aircraft for simulation in X-Plane. That will save you having to go to the aircraft file and delving through the plugins folders to remember what route "Co" name you saved it under, a nice time saver. I also found you can now see the Co (company) route to load it into the FMC system. ![]() For me this is welcome because you actually had to move you point of view to arm the speedbrakes, a small thing but nice. There is now also new mouse wheel support (Microsoft C++ redistributable 2013 is required for this to work) for Windows users.Īnother change is that now you click the actual speedbrake lever and not the area by the side of the lever. Side airport map panel looks better as well for quality and readability. Spot light lighting is also improved as you can see behind the pilot's chairs, these lights are well up and behind and buried in the rear of the cockpit. They have gone from a yellowish glow to a greenish glow, but the newer upper images version does look more restrained and more natural. The older night textures looked like this. There has been far more changes here than meets the eyes, but most will be overlooked as we are very used to most of it. The side (autopilot) eyebrow/glareshield form is much more better as well, and finally you can't finally see the outside scenery through the main instrument panel (top under the glareshield) so your eyes are picking off the changes all over the place and overall it looks far better. At first it doesn't look much different (because it is so familiar) but after a short period of flying the aircraft you do notice how much more sharper and cleaner everything is, notice the active lighting on the buttons and you can see how much more realistic they are, and some areas are based on the textures used by the 3rd party (pumper) that was significant in the redefining of the cockpit textures. So FlightFactor/VMax has redone the cockpit textures and cleaned up a lot of the knobs and switchgear and the right hand side MFD can now be used. But everyone was happy, and what we need in X-Plane is happiness. Even a 3rd party redid the whole lot of textures to which again I couldn't see the really big significant difference? and it was worse on your framerate. Personally I couldn't see the argument to the point of how notably the textures of being that bad, not perfect I admit as were the gaping holes in the windshield. There was a lot of discussion around the cockpit textures since the release of the aircraft, most notable was that they were average or poor. This aircraft is quite mature now (as I have noted in other updates) but the odd tweak now and again does not hurt the design. This update is basically revolves around the cockpit and not many changes to the flight or external sections of the aircraft. The "Triple Seven" as it is also called, is the world's second largest twin-engine airliner and has now been converted one to one for X-Plane.Aircraft Update : Boeing 777 Worldliner Pro/Extended v1.8 by FlightFactor/VMaxįlightFactor/VMax have updated their excellent Boeing 777 Series Pro and Extended versions to v1.8. The Boeing 777, a superlative of a long-range airliner is now also available for your flight simulator at home. Thanks to technical input from engineers, pilots and the Boeing © Corporation, one of the most advanced and complex simulations of an aircraft for X-Plane has been created. ![]() This is a serious upgrade from the puny stock bars, both measuring less than one inch. I chose Addco’s “Hot” offering: a pair of bars measuring a stout 1 ¼” in diameter. ![]() Moderation and parts matching is paramount. So I had a dilemma not unlike a trip to the hot sauce counter at Taco Bell: will it be “Mild”, “Hot” or “Fire”? Obviously this Lincoln is not the logical choice, but as a cousin of the Ford Thunderbird, Addco’s engineers worked with the road racing T-bird faithful (who knew?) to create three options for my wannabe GT. So TTAC’s test vehicle for Addco’s bars is my daily driver: a Lincoln Mark VIII LSC with a fully refreshed air suspension. So Addco Manufacturing, one of the few suspension suppliers with the flexibility and knowledge to create sway bar upgrades for most any ride, feeds the need for flat cornering.ĭisclaimer: while some vehicles have sway bar alternatives from their high(er) performance counterparts (a la Ford SVT or BMW M-series), buying used sway bars may not give the desired bang-for-the-buck when you consider metal fatigue, worn bushings and unrealistic pricing due to a limited supply. Even worse, many rear bars are deleted entirely to please the merciless will of corporate beancounters. Most cars come with a Pistonhead-averse, lawsuit-friendly pair of bars. With this in mind, start with better tires, and then take a look at your sway bars. For the rest of us, there are after market alternatives that allow loyalists to keep their current rides (and monthly payment) and let the inner Pistonhead shine in all its glory. Unless you own the well engineered underpinnings of a Porsche, Corvette, BMW or a handful of less obvious winners sporting a bona fide performance suspension from the factory, that is. There’s nothing like matching wits with the sweepers in a car that normally fears a bend in the road. ![]() Just bad and they don’t care or listen when you email them about the issues.

It is the maximum amount of data that can be transferred by or within the network. Here is everything you need to know about your bandwidth and how to test it easily: What is Bandwidth?īandwidth, as a general rule, is a measurement of how much traffic a connection can handle at the same time. That way, you know if you have a problem, you will know what to do next. However, what might be more important is that you have the contextual information and knowledge to make the most of the results. ![]() You just need to use a speed test along with perhaps a few other tools. The good news is that you can test your bandwidth very easily. When it comes to things such as conferencing gaming, remote work needs, streaming, and so much more, are you getting the reliability and service you should be getting? An ISP should be meeting the needs of its users. And that last part is especially important, given that you are paying your internet provider for services, and you should be getting those services. You might be wondering exactly what it is, how important it could be, and what yours is. How fast is your internet? Find out now with the accurate and easy-to-use Speedtest from speed.io.If you’re reading this, you might be interested in learning more about bandwidth speed. The following is an overview of the theoretical highest download speeds so you can compare your test results to see just how well your speed measures up. Your maximum possible data transmission speed depends on whether you have a broadband, fibre, WiFi or another connection, as well as your pricing plan and service provider. What data transfer rates should you expect to see in the test results? Pings refer to the response delay, which is particularly interesting to gamers. ![]() Connects show you the number of connections that can be established simultaneously, and the higher the value, the better. The upload value indicates how quickly you can transfer files from your computer, which is important to know for those who regularly use cloud services to store files. The download value tells you how much data your WiFi or broadband connection can move from the World Wide Web to your computer. The test results for your broadband or wireless network are broken down into four parts: download, upload, connects, and pings. The test program then establishes a link with three nearby servers and measures the speed of your broadband / fibre / wireless connection. Simply ensure that your computer or mobile phone / tablet is connected to the internet either directly via a router with a network cable or via a WiFi network and press the start button on the speed.io website. The speed test gives you the tools you need to run the test entirely in your browser. Armed with the test results from your speed test, you can optimise your connection and get the most out of your online experience.

T ype of project: Sound Mod - Texture Mod + Door Mod ![]() Yet another way that people make sounds is through playing musical instruments (see the previous figure). Additional processing in the brain also allows us to determine which direction the sound is coming from (based on comparison of the sound’s arrival time and intensity between our two ears).įigure 14.13 Playing music, also known as “rocking out”, involves creating vibrations using musical instruments. This allows us to detect the pitch of sound. The tectorial membrane vibrates at different positions based on the frequency of the incoming sound. These hair cells, and their attached neurons, transform the motion of the tectorial membrane into electrical signals that are sent to the brain. The motion of the tectorial membrane stimulates tiny cilia on specialized cells called hair cells. This creates pressure waves in the fluid that cause the tectorial membrane to vibrate. As the middle ear bones vibrate, they vibrate the cochlea, which contains fluid. This protective reaction can also be triggered by your own voice, so that humming during a fireworks display, for example, can reduce noise damage.įigure 14.12 shows the middle and inner ear in greater detail. They react to intense sound in a few milliseconds and reduce the force transmitted to the cochlea. Two muscles in the middle ear protect the inner ear from very intense sounds. The lever system of the middle ear takes the force exerted on the eardrum by sound pressure variations, amplifies it and transmits it to the inner ear via the oval window. The middle ear converts sound into mechanical vibrations and applies these vibrations to the cochlea. The outer ear, or ear canal, carries sound to the eardrum protected inside of the ear. ![]() The body part normally referred to as the ear is technically called the pinna.įigure 14.11 The illustration shows the anatomy of the human ear. The ear converts sound waves into electrical nerve impulses, similar to a microphone.įigure 14.11 shows the anatomy of the ear with its division into three parts: the outer ear or ear canal the middle ear, which runs from the eardrum to the cochlea and the inner ear, which is the cochlea itself. The sound wave that hits our ear is a pressure wave. The way we hear involves some interesting physics. The perception of frequency is called pitch, and the perception of intensity is called loudness. Sounds below 20 Hz are called infrasound, whereas those above 20,000 Hz are ultrasound. You may have noticed that dogs respond to the sound of a dog whistle which produces sound out of the range of human hearing. Dogs can hear sounds as high as 45,000 Hz, whereas bats and dolphins can hear up to 110,000 Hz sounds. Other animals have hearing ranges different from that of humans. Humans can normally hear frequencies ranging from approximately 20 to 20,000 Hz. It can give us plenty of information-such as pitch, loudness, and direction. A voice becomes louder when air flow from the lungs increases, making the amplitude of the sound pressure wave greater. A voice changes in pitch when the muscles of the larynx relax or tighten, changing the tension on the vocal chords. This vibration escapes the mouth along with puffs of air as sound. ![]() As air travels up and past the vocal cords, it causes them to vibrate. These folds open and close rhythmically, creating a pressure buildup. People create sounds by pushing air up through their lungs and through elastic folds in the throat called vocal cords. Power is the rate at which energy is transferred by the wave. In general, the intensity of a wave is the power per unit area carried by the wave. ![]() Figure 14.10 shows such a cartoon depiction of a bird loudly expressing its opinion.Ī useful quantity for describing the loudness of sounds is called sound intensity. In cartoons showing a screaming person, the cartoonist often shows an open mouth with a vibrating uvula (the hanging tissue at the back of the mouth) to represent a loud sound coming from the throat. But in a traffic jam filled with honking cars, you may have to shout just so the person next to you can hear Figure 14.9.The loudness of a sound is related to how energetically its source is vibrating. In a quiet forest, you can sometimes hear a single leaf fall to the ground. Sound intensity is defined as the sound power per unit area, whereas amplitude is the distance between the resting position and the crest of a wave. While sound intensity is proportional to amplitude, they are different physical quantities. Students may be confused between amplitude and intensity. |
