Product Review: Howell H1900 Series

Every aircraft has a need for detailed usage statistics and in-flight details that alert pilots and even ground-crew as to the health and condition of the craft and its components, as well as variables that crop up during flights.

The more detailed and easily accessed this information is, the better it is for craft safety and comfort. It also allows craft owners to keep better tabs on maintenance tasks that need to be conducted.

The Howell H1900 series Cockpit Indicator and Engine Monitor does just this thanks to its multifunctional design.

Here we will review this exceptional piece of aviation tech in terms of its most important features and functions, as well as the benefits it offers to those crafts that it is fitted to.

We will start by explaining what exactly the H1900 indicator is and what it does and will explore its display and monitoring functions in a bit more detail.

From there we will take a look at some of the best advantages that aircraft owners and piolets can get from using these devices.

So, let’s begin by taking a look at what exactly the Howell H1900 series indicator/monitor is:

What is the Howell H1900 Indicator/Monitor?

The Howell H1900 series indicator and monitor is a remarkably built, state of the art cockpit indicator as well as an engine monitor.

This dual function makes it an excellent addition to any cockpit, and it provides piolets with detailed information about both the flight as it takes place, as well as the condition and historical use of the aircraft that it is fitted to.

This system is also completely customisable, allowing for reprogramming using associated software so that it can fit the needs and preferences of particular piolets.

They are also password-protected to prevent tampering, and by using these systems, piolets can be given real-time, detailed information about just about all aspects of the flight and craft.

This provides an important point for leveraging safety, in-flight comfort and the reliability of the craft against the important information surrounding the craft that ensures these factors can be properly controlled; by providing what the piolet needs to know about the engine, the condition of the craft’s oil, as well as details about the identity of the craft and its many components.

Primary Display Options

Let’s take a look at the primary functions offered by the Howell H1900 series’ cockpit indicator operations.

These primary display functions for piolets offer detailed information about many important aspects of the craft during operation; including engine speeds, temperatures and torque, engine pressure ratios, fuel flow and pressure, oil pressure and temperature, outside air temperature, as well as DC voltage:

Engine Speed

The Howell H1900 series cockpit monitor provides piolets of varying different types of craft with detailed information about the engine speed of the plane while in operation.

Compared to other modes of transport, aircraft engines are designed to provide maximum power at comparatively low RPM.

The information about engine speed provided by the Howell H1900 series monitor gives piolets an overview of this ratio so that they can be alerted to any potential problems in relation to engine speed and power.

Engine Temperature

Engine temperatures, especially on commercial aircraft, can often exceed temperatures of 2000 degrees Celsius, which is a substantial amount. Especially when you consider that the metals used in the construction of these engines, generally starts to melt at around the 13000-degree Celsius mark.

Besides needing specialised cooling techniques to prevent this from happening, piolets naturally need to be able to keep close tabs on engine temperatures to ensure that they don’t exceed safe operational limits, making this particular function of the Howell H1900 series an important one indeed.

Engine Pressure Ratio

The engine pressure ratio is determined by the relationship between the pressure at the exit of the propeller and the total pressure at the compressor’s entry.

To work this out, the former is divided by the latter to work out the total engine pressure ratio (or EPR).

This pressure can be used as an indicator of thrust in jet engines, making it important for piolets to understand and know what this ratio is at any given point in the flight.

This means that this information needs to be made available at a glance, which is something that the Howell H1900 series can provide to piolets while in the air.

Fuel Flow & Pressure

Incorrect supply of fuel from the main tanks to the fuel pump inlet should also be consistently stable and reliable to ensure the performance and safety of the craft during operations, with discrepancies needing to be noted as a potential problem with the craft.

Again, this makes this particular type of information essential to piolets, especially while they are in the air.

The Howell H1900 series makes this information readily available to piolets and crew, in an easy to understand format.

Oil Pressure & Temperature

Pressure instruments are widely regarded as some of the most important components for aircraft, especially where engine oil pressure and temperature gauges are concerned.

In just about any combustion engine (including those on most types of aircraft), the relationship between oil pressure and oil temperature is a closely aligned one.

When the engine is cool, the oil will also be cool, which means that it will be more viscous, and will, therefore, result in higher pressures.

As the engine heats up, the oil does too, and becomes less viscous, which in turn should lower the pressure in the engine.

Noticing any discrepancies here can help piolets take better care of the condition of their craft’s engines, ensuring that they last longer and get maintenance or repairs as soon as they need them.

The fact that the Howell H1900 series provides this information as part of its many functions, makes it highly beneficial to any aircraft it is fitted to.

Monitoring Functions

Now let’s take a closer look at the features offered by the other side of the Howell H1900 series functionality coin.

These functions are geared more towards identifying the craft and its components, as well as documenting their usage, maintenance and health.

This makes the Howell H1900 series an excellent addition for those looking to stay on top of craft health and maintenance tasks, or when documenting how and when the craft has been used.

This can be particularly helpful on commercial planes that might be operated by more than one piolet in its lifetime.

These functions include identification of the craft and its usage, its hot-section exposure, and its exceedance data.

Let’s take a closer look:

Identification & Usage Data

The identification and usage data provided to piolets and crew through the Howell H1900 series includes the craft engine number, how many times it has been started, how many hours the engine has been in operation for, and its cycle counts.

Craft Engine Number

An identification number on an aircraft is frequently used to do just that, identify what craft it is, which can also be tied to who its owner is, where it flies to, what type of aircraft it is and a lot of other information.

It might not seem like a big deal, but for the crew that works with multiple aircraft, being able to have the details of an aircraft and its engine identity on hand, can help organisations take better care of their craft, by mapping them and their condition.

This information is provided through the use of a Howell H1900 series monitor.

Engine hours

When it comes to maintenance, repairs, reporting and investigation purposes, it is often essential for crew and craft owners to know exactly how many hours their craft’s engine has been in operation for.

This gives personnel an idea of the engine’s condition, how reliably and safely it can be used and when the craft is due for maintenance.

This essential information can be measured and reported on seamlessly by using a Howell H1900 series inspector.

Engine Cycle Counting

Engine cycle counting takes into account all possible aspects and operations of a single trip that an aircraft takes.

The information included here should detail activities such as engine starts, take-off and landing, taxying and shutting down.

Again, by using a Howell H1900 series monitor, this information can be given to crew and piolets in real-time and can be easily documented as well.

This information can be used to determine what kind of strain the craft is put under so that an appropriate maintenance plan can be determined.

Hot Section Inspections

The Hot-Sections of aircraft are those that are generally associated with extremely high temperatures during operations, and as such, present somewhat of a risk of danger. Because of this, these parts need to be regularly inspected by an engineer to ensure that the aircraft can be used safely.

These areas of the plane include the sections associated with combustion, turbines and exhausts.

By implementing the Howell H1900 series monitor in any craft, details about the Hot-Sections of a plane can be given to engineers in detail, to ensure that any troublesome components are repaired in good time.

Exceedance Data

The Howell H1900 series monitor provides exceedance data based on historical flight records (FDR Flight Data Records) to identify troublesome trends that could, at a later stage result in potential accidents occurring.

The goal behind using this information is that it allows airlines and piolets to take a proactive approach to identify what may cause these accidents so that preventative measures can be taken to avoid them effectively.

This is particularly the case where chronic failures of aircraft systems may otherwise go unnoticed until such time that they present a real threat of danger.

Because of this, the Howell H1900 series monitor makes it possible for airlines to ensure that every aspect of in-air safety is upheld to the highest degree.

Benefits & Features

With all of this in mind, it is fairly easy to see how beneficial the Howell H1900 series monitor/inspector can be to airlines and craft owners of all types. It offers a simple, turn-key solution for monitoring multiple aspects of both the craft and its trips, so that information can be used to improve the safety, comfort and experience of the craft.

Three of the top benefits to this include being given real-time alerts and data relating craft health and condition, being able to log a history of engine usage and condition for maintenance and safety reasons, as well as providing in-depth details of environment and craft variables during a flight.

Real-Time Alerts & Data on Craft Health

Piolets and engineers can get information about the condition of an aircraft and its many components in real-time, either as they occur or when components are due to fail.

This allows them to be more proactive when it comes to dealing with potential problems, maintaining the craft, or just ensuring its overall performance and safety.

Logged History of Engine Usage & Condition

The Howell H1900 series provides information that can be easily recorded, that relates to just about all areas of the craft’s usage and condition.

This information can be used in the future to determine things like maintenance schedules when replacements need to be made, or how much longer the craft can be used before it needs to be retired.

In-Depth Flight Details

These systems also give piolets and crew an in-depth overview of a number of flight details including outside air temperature, engine performance and oil pressure and temperature, which enables them to ensure that components are performing to expectations, even during a flight.
