What Would Be Found on a Type Certificate Data Sheet for an Aircraft?

If you are involved in the aviation industry or have an interest in aircraft, you may have come across the term “Type Certificate Data Sheet” (TCDS). A TCDS is a vital document that contains important information about an aircraft’s design, configuration, limitations, and performance.

It serves as a reference for regulatory authorities, manufacturers, operators, and maintenance personnel. Let’s take a closer look at what you can expect to find on a typical TCDS.

1. Aircraft Identification

The TCDS begins with the identification of the aircraft type and model.

This includes the manufacturer’s name, model designation, serial number range, and any applicable variant or sub-variant information. This section ensures that there is no confusion regarding the specific aircraft being referenced.

2. Type Certification Basis

Next comes a detailed description of the basis on which the type certificate was granted by the aviation regulatory authority.

This typically includes references to relevant regulations and standards that were used during the certification process. It provides important context for understanding the design and operational requirements that were met by the aircraft.

3. General Description

The general description section provides an overview of the aircraft’s design and construction features.

It includes details about its overall dimensions, weight limits, seating capacity, fuel capacity, and cargo capacity. This information helps operators understand the basic characteristics of the aircraft.

3.1 Airframe

This subsection focuses specifically on the airframe structure of the aircraft. It provides information about materials used in construction, structural configurations, landing gear arrangements, and other relevant airframe details.

3.2 Powerplant

In this subsection, you will find information about the aircraft’s engines, including the manufacturer, model, and specifications. It also includes details about any propellers or thrust reversers that may be installed on the aircraft.3 Systems

This section covers various systems installed on the aircraft, such as electrical, hydraulic, fuel, and environmental control systems. It provides an overview of how these systems are designed to function and any limitations associated with their operation.

4. Performance Information

The performance information section is crucial for pilots and operators as it provides data related to the aircraft’s performance capabilities under different conditions.

4.1 Operating Limitations

This subsection outlines the aircraft’s operating limitations, such as maximum takeoff weight, maximum landing weight, maximum altitude limits, maneuvering speed limits, and other important restrictions that must be adhered to for safe operation.2 Performance Data

This subsection presents data related to the aircraft’s takeoff performance, climb performance, cruise performance (including speed ranges and fuel consumption), descent performance, and landing performance. This information helps pilots plan flights more effectively and optimize fuel consumption.

5. Weight and Balance

The weight and balance section provides critical information regarding the distribution of weight within the aircraft. It includes details about empty weight, maximum ramp weight, maximum takeoff weight, maximum landing weight, center of gravity limits for different configurations, and any specific procedures or restrictions relating to loading or unloading cargo/passengers.

6. Equipment List

In this section, you will find a comprehensive list of equipment installed on the aircraft.

It includes avionics systems (communication/navigation/instrumentation), safety equipment (fire extinguishers/escape slides), and any optional or special equipment installed. This helps maintenance personnel identify the equipment on board and ensures that all necessary systems are present and functioning properly.


A Type Certificate Data Sheet is a valuable resource that consolidates important information about an aircraft’s design, performance, limitations, and equipment. By providing a standardized format for presenting this information, TCDSs help ensure safety, regulatory compliance, and operational efficiency in the aviation industry.
