Just so we are on the same page, CHT stands for Cylinder Head Temperature and EGT stands for Exhaust Gas Temperature and in the case of this article, these refer to the aircraft engine cylinder and aircraft engine exhaust gases (same terminology is also used in high-performance cars). Before we get on to the use of CHT and EGT gauges and monitors, we need to first understand CHT and EGT data. CHT and EGT provides information of two different things that is happening inside the aircraft engine. The former i.e. CHT data specifically points to …

When the passengers are informed that an aircraft cannot take off due to technical reasons, it usually means that the airline not only has to have the aircraft towed away for expensive emergency repairs, it has to make alternate arrangements to fly the passengers maybe even provide accommodation and food while the passengers are waiting. All put together, it can be one big frightful bill and just a few of these in a year would be enough to dent the airline's profitability. The above is of course, is the better scenario when compared to an ai…

The basics of electronic data management systems (EDMS) in aircraft are pretty simple. The EDMS essentially consists of two parts – probes & sensors and the display unit(s). The probes and sensors are located at various critical parts of the aircraft and convert heat, pressure or whatever it is supposed to sense, into electrical signals usually in the form of volts. These signals are interpreted by the display unit and displayed in a manner that makes sense to the pilot(s). There are two types of probes and sensors used in modern aircraft; i…

During World War II and in response to the war ministry's directives, aircraft manufacturers had to constantly try and improve the engine power as well as the range of their aircraft – especially the bombers. The pressure to increase power and range happened with both – the allied forces and Nazi Germany. So how does the presence of an EGT probe and the Exhaust Gas Temperature display unit (EGT) help improve aircraft power, range and assist in precision engine monitoring? This is how it worked: If fuel is not efficiently burnt, it passes o…

An aircraft digital instrument and monitoring system is not something you find in a aircraft maintenance garage; it is something you find inside the cockpit of a modern or an upgraded aircraft. Aircraft Digital Instrument and Monitoring System basically replaced the OEM vintage dials and gauges that aircraft until a decade or so ago, came equipped with. With digital age came the opportunity to combine all (as in the case of single and twin engine aircraft), or groups of dials and gauges into a single digital monitoring instrument or displa…

Imagine if for every app in your computer you needed a separate display screen – boggles the mind don't it? And yet, there are a large number of single and twin engine aircraft still flying that have one display gauge per sensor type. When these planes were manufactured, digital technology either did not exist or was at a very nascent stage. This is not the case today so unless life means little to you and you are still flying an aircraft with its cockpit loaded with dozens of dials, now is the time to upgrade. Replace all those dials and g…

Aircraft cockpits have evolved from being a dimly lit, tiny cabin with three or four dials, steering column and rudder controls to a modern flight deck with digital screens that take care of almost everything except take off and land. As aircraft's developed so did the number of dials in the aircraft cockpit. Pretty soon the aircraft cockpit was a crowded place with dozens of dials fighting for space and the pilot's attention. The pilots not only had to fly the aircraft, they also had to observe each and every dial and figure out the health …

If you are still calculating fuel status manually then isn't it high time you switched over to an automatic single or multi-engine aircraft fuel management system – if not for your own safety, at least for the safety of your passengers? A modern single or multi-engine aircraft fuel management system especially like the ones manufactured by J.P. Instruments not only just displays the fuel consumption and fuel in the tank(s), it can be integrated with your GPS so you know if there will be enough fuel for your selected flight path. You can even…

A flexible aircraft fuel gauge is one that can be programmed by the pilot. By powerful we mean it can automatically provide data to your GPS or on-board integrated electronic flight instrument system which in turn can calculate fuel status for a particular flight path or destination. Difficult to believe but there are many pilots out there that still rely on the old method of calculating fuel use i.e. with a calculator. Flying since before the digital age when aircraft gauges used to be faulty at best, they think the manual way of calculatin…

Ever since humans have learnt to fly, aircraft technology has taken giant leaps and continues to advance even further. Today, the pilot knows just about everything that is happening in the plane - from the cockpit to the aircraft tail and everything in between and have that information thanks to sensing systems installed in the aircraft. Modern aircraft whether single or multi-engine have numerous sensors fitted all over the aircraft. These sensors range from array pressure sensors, temperature and non-temperature compensated pressure sensor…
