An air data computer (ADC) is an essential avionics component found in modern aircraft.  This computer, rather than individual instruments, can determine the calibrated airspeed , Mach number , altitude , and altitude trend data from an aircraft 's pitot-static system . [1] [2]   In some very high speed aircraft such as the Space Shuttle , equivalent airspeed is calculated instead of calibrated airspeed . Air data computer Air data computers usually also have an input of total air temperature . This enables computation of static air temperature and true airspeed . In Airbus aircraft the air data computer is combined with altitude, heading and navigation sources in a single unit known as the Air Data Inertial Reference Unit (ADIRU) this has now been replaced by the Global Navigation Air Data Inertial Reference System (GNADIRS).

  Oil Temp Probe In Aircraft And Its Advantages Facebook LinkedIn Twitter Download as PDF Be it a car, truck, bike or a plane, most of us are just content in flying it or driving it.  Not many have so much as seen the engine under the hood or even know what it looks like. And then, there are others who need to not only see but need to feel, to know what each part does and its importance in the entire machine.  <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = window.adsbygoogle || []).push({}); </script> Today, let us consider the Oil Temp Probes in airc...

     In radio communications, a radio receiver, also known as a receiver, a wireless or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form.  It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = window.adsbygoogle || []).push({}); </script>  The receiver uses electro...

What is RMS Voltage ? The RMS or effective value of a sinusoidal waveform gives the same heating effect of an equivalent DC supply In our tutorial about the AC Waveform we looked briefly at the RMS Voltage value of a sinusoidal waveform and said that this RMS value gives the same heating effect as an equivalent DC power and in this tutorial we will expand on this theory a little more by looking at RMS voltages and currents in more detail. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = window.adsbygoogle || []).push({}); </script> The term “RMS” stands for “Root-Mean-Squared”...

What is a digital multimeter? A digital multimeter is a testing tool that is used to measure two or more electrical value I.e principally voltage (volts), current (amps) and resistance (ohms).   digital multimeter is a standard diagnostic tool for technicians in the electrical/electronic industries. Digital multimeters long ago replaced needle-based analog meters due to their :-  1 ability to measure with greater accuracy, 2 reliability  3 increased impedance Fluke introduced its first digital multimeter in 1977. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = w...

The National Fire Protection Association (NFPA) developed a hazard identification system for emergency responders that is still in use today. In the past some chemical manufacturers used NFPA diamonds on their products, but now labels are required to use GHS labeling. This section briefly explains the NFPA system. The NFPA diamond provides a quick visual representation of the health hazard, flammability, reactivity, and special hazards that a chemical may pose during a fire. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = window.adsbygoogle || []).push({}); </scrip...

The hearing protection is used to reduce or limit (attenuate) noise reaching the wearer’s ears,  and thus it reduce the risk of hearing damage from excessive or loud noise. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = window.adsbygoogle || []).push({}); </script> The effectiveness of hearing protection is often limited by personal and workplace factors, and it can reduce the audibility of warning sounds.  For these reasons hearing protection must be selected and used with care and is not to be used as an alternative to reducing the noise in the workplace.

Bonding is the joining of metal pieces to form a conducting path while grounding is any intentional or accidental connection between an electrical circuit or instrument and the earth 2.Bonding ensures safe electrical continuity while grounding ensures that all metal parts of an electrical circuit that an individual might contact are connected to the earth, thus ensuring zero voltage. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle"      style="display:block; text-align:center;"      data-ad-layout="in-article"      data-ad-format="fluid"      data-ad-client="ca-pub-3594006331358944"      data-ad-slot="7745808678"></ins> <script>      (adsbygoogle = window.adsbygoogle || []).push({}); </script> 3.Bonding is achieved by using a wire while grounding is achieved by using a rod. 4.Bonding provides t...
