Definition
A formal FAA document that records the approved configuration and operating limitations of a specific aircraft, engine, or propeller type. It lists items such as approved engine models, fuel grades, weight and balance limits, control surface movement ranges, airspeed limits, and any conditions or equipment required for the type certificate to remain valid.
Plain English
An official FAA sheet that describes exactly how a certain aircraft model was approved — what engine it can use, what fuel it needs, how much it can weigh, and the limits it must operate within.
Context Anchor
A pilot may see TCDS mentioned during preflight assessment, aircraft document review, maintenance discussions, or when checking whether an aircraft matches its approved configuration.
Derivation
‘Type certificate’ refers to the FAA approval issued for a specific design (the ‘type’) of aircraft. The ‘data sheet’ is the document that records the details of that approval. Together, the term simply means the official record of what was approved for that aircraft type.
Why Pilots Care
They contain the legally binding limits a pilot must observe for safe and legal operation of that aircraft type.
Intuition Check
Do not think of a TCDS as a quick checklist or a pilot operating handbook. It is an FAA approval record for the aircraft type, mainly used to confirm approved design information and limits.
Example Sentence 1
Before signing off the annual inspection, the mechanic checked the TCDS to confirm the installed propeller was an approved model for that airframe.
Example Sentence 2
Preflight review of the TCDS verified that the installed propeller met the approved specifications for the model.
