The Compressor Discharge Temperature (CDT) probe (not to be confused with Conductivity, Temperature, Depth probe used in ships and also called CDT probe), is installed in the engine compartment just after the inter-cooler. The probe is installed with a #40 stainless steel clamp. A large clamp is supplied to fit around the air-port leaving the inter-cooler.

A typical CDT probe kit from J.P Instruments includes the thermocouple type ‘K’ CDT Probe, a stainless steel clamp thimble, one stainless steel exhaust seal washer and one stainless steel screw type clamp.

The aircraft fuel scan 450 Twin manufactured by J.P. Instruments, is probably the best fuel indicator to date. This is a product engineered by aeronautical engineers (nothing new there), but; hold your breath, was designed by bunch of experienced pilots which is why it has all the features and functionality that you as the pilot or aircraft owner might love to have in a fuel indicator.

I won’t insult your intelligence by writing that this is a digital fuel indicator! Of course, it is digital – which modern day fuel indicator isn’t? That said and for its size, it uses an amazing display ... Read more »

Aircraft Engine Data Manager 740 for experimental aircraft is an awesome product that is innovative and aggressively priced.

Starting at $2899 for a 4-cylinder installation and $3250 for a 6-cylinder one, the EDM-740 covers all the basics that a pilot requires to fly the aircraft safely. This includes the most of the popular sensors. Optionally you can add turbine-inlet temp, electrical-bus current, carb temp and fuel pressure sensors. Also, if you have the sensors installed, it can also read resistance or capacitance of fuel-level senders.

Similar to earlier EDM’s, the EDM-740 stacks EGT and CHT Monito ... Read more »

There are many parts and components in an aircraft that do not generate their own heat and instead, rely on heat generated from the engine. Of all these non-heat-generating components or parts, the aircraft carburettor is perhaps the most vulnerable to humidity and low temperatures. The freezing of the aircraft carburettor would not just impede the smooth functioning of the engine, it will ultimately stop the engine from functioning!

To prevent the above from happening, an anti-icing system that preheats the air before it reaches the carburettor is put in place. This is intended to keep the fuel-air mixture warm enough so that freezing does not occur and ... Read more »

Imagine flying an aircraft with no engine monitors or engine gauges. As a pilot, you wouldn’t know what is happening in the engine compartment – whether the cylinders are over-heating, whether an engine starved of fuel, or, whether the aircraft engine is about to suffer a catastrophic failure that could end your flight in total disaster!

Aircraft engine monitors and aircraft engine gauges are a set of instruments located in the cockpit of an aircraft. These engine monitors and gauges supply the pilot with data regarding the health of the engine and its current performance in real-time.

Every engine be it an aircraft eng ... Read more »

Engine data management 700 which can simply be referred to as EDM 700 is a necessary addition to any aircraft. It works by continually monitoring the engine activities of the aircraft thus, leaving the pilot to fully concentrate on flying and landing the aircraft safely. With the help of the latest microprocessor technology, a total of 24 critical parameters are monitored 4 times a second which is more than can be done by the pilot.

The EDM 700 system is also able to instantly give warning when programmed limits are exceeded. This is possible because it is equipped with an up to date warning system. It is the most accurate, advanced engine monitoring system in th ... Read more »

It is important to check the fuel level before the start of a journey. This is necessary for any means of transportation – cars and aircrafts. This is required in order to avoid stopping and refueling alongside the delays and inconveniences that may result.

There are some devices that can be installed in an aircraft that can accurately determine the fuel level. They are necessary in order to minimize disasters that may result when an aircraft runs low on gas. These devices are called fuel flow indicators. They operate on several basic principles that are all aimed at determining the precise level of ... Read more »

What are Aircraft Instruments?

Aircraft pilots cannot just look out of the window and know where they and what is going on around them. They instead rely on instruments. Instruments essentially concern measurement. Common aircraft measurements include fuel consumption, direction, position, speed, and altitude.

Aircraft instruments are basically grouped in two ways: 1) work performance; and, 2) operating principles. Instruments that measure work performance include vertical speed, altimeter, and airspeed. The basic principles of engine operation concern the relationships between the te ... Read more »

Airplane fuel gauges are somewhat similar to vehicle fuel gauges in that they both indicate the quantity of usable fuel present in the fuel tank. However, airplane fuel gauges work at a more complex level simply because aircraft carry more than one fuel tank and they also have more than one engine. Besides, reading fuel levels becomes complicated due to the fluctuating fuel density resulting from the changing aircraft altitudes.

To explain the workings of an airplane fuel gauge in a simplistic manner: a float level gauge is fitted to each of the fuel tanks in the aircraft. These gauges feed the information pertaining to fuel level in each tank ... Read more »
