Review KELLY MANUFACTURING CAMPANY Company Cessna Low Voltage Warning Sys

The Kelly-Campany 33-2013A Voltage Warning System is an essential avionics upgrade for Cessna 172E aircraft, designed to provide pilots with critical electrical system information. This innovative system offers enhanced safety and peace of mind during flight.

The Voltage Warning System utilizes a three-circuit design, allowing it to monitor the electrical loads of the primary flight instruments, master warning system, and avionics separately. Each circuit features a voltage sensor and an ampere sensor, enabling the system to detect both voltage drops and overloads.

The system's microprocessor-based design offers advanced features, such as adaptive threshold settings for each circuit, which automatically adjust based on engine RPM and temperature. This ensures accurate and reliable voltage and ampere readings, even under varying flight conditions.

The system's display provides clear and easy-to-read information, with individual circuit warnings indicated by red LEDs, along with a digital readout of the voltage and ampere levels for each circuit. Additionally, the system includes a backlight for improved visibility during low-light conditions.

Installation of the Kelly-Campany 33-2013A Voltage Warning System is straightforward, with a plug-and-play design that minimizes the need for modifications to the aircraft's wiring. The system includes all necessary mounting hardware and comprehensive installation instructions.

The Voltage Warning System is an essential addition to the avionics suite of any Cessna 172E aircraft, providing pilots with real-time electrical system information and early warning of potential issues. This system offers peace of mind, enabling pilots to focus on the task of flying while the system monitors the aircraft's electrical system.

Pros and Cons of Buying a Cessna 172E (Kelly-Campany 33-2013A) with a Voltage Warning System

The Cessna 172E (Kelly-Campany 33-2013A) is a popular light aircraft model known for its versatility and reliability. Installing a voltage warning system can enhance safety by providing pilots with essential electrical system information. In this analysis, we will discuss the advantages and disadvantages of purchasing a Cessna 172E with a pre-installed voltage warning system.

1. Enhanced Safety: A voltage warning system alerts pilots when the electrical system voltage drops below a safe level. This information can help prevent damage to the aircraft's electrical components or even an engine failure.

2. Improved Situational Awareness: With a voltage warning system, pilots have real-time information about their electrical system's status, allowing them to make informed decisions during a flight.

3. Maintenance Optimization: Regularly monitoring the electrical system voltage can help pilots identify potential issues before they become significant problems, reducing maintenance costs and downtime.

4. Increased Value: A pre-installed voltage warning system can be an attractive feature for buyers when selling the aircraft, potentially commanding a higher resale value.

1. Initial Cost: Installing a voltage warning system can be an additional expense when purchasing a Cessna 172E. The cost varies based on the specific system and installation labor.

2. Complexity: A voltage warning system adds another layer of complexity to the aircraft's electrical system. This might require additional training for pilots and ground crew to understand and maintain the system effectively.

3. False Alarms: Although rare, a voltage warning system might generate false alarms due to electrical system fluctuations or temperature changes. This could lead to unnecessary concerns and potential distractions for pilots.

When considering purchasing a Cessna 172E with a pre-installed voltage warning system, it's essential to weigh the advantages against the disadvantages. The enhanced safety, improved situational awareness, maintenance optimization, and increased value make a strong case for the benefit of such a system. However, the initial cost, complexity, and potential for false alarms are valid concerns that should be taken into account. Ultimately, the decision to buy a Cessna 172E with a voltage warning system depends on each individual's priorities, budget, and flying requirements.

If safety and situational awareness are top priorities, or if you frequently fly in remote areas with limited resources, investing in a Cessna 172E with a pre-installed voltage warning system could be a wise decision. However, if budget is a concern, or if the complexity of the system doesn't justify the potential benefits for your flying style, it may be best to consider other aircraft models or aftermarket installation options.
