Definition
A label printed on the face of a turn coordinator indicating that the instrument senses yaw and roll only, and does not display the aircraft's pitch attitude (nose-up or nose-down angle). It is a reminder that the turn coordinator cannot be used to determine whether the nose is climbing or descending.
Plain English
A note on the turn coordinator that tells you this instrument will not show you whether the nose is pointing up or down. It only shows turning and banking.
Context Anchor
Seen in descriptions of the turn coordinator, especially when comparing what it can show with what an attitude indicator can show.
Why Pilots Care
Relying on the turn coordinator for pitch attitude can lead to loss of control or entry into an unusual attitude; the attitude indicator must be used instead for pitch reference.
Intuition Check
Do not read pitch here as sound or tone. In this context, pitch means the airplane’s nose-up or nose-down attitude, and the turn coordinator does not show it.
Example Sentence 1
The instructor pointed to the words 'No Pitch Information' on the turn coordinator and reminded the student to cross-check the altimeter for any climb or descent.
Example Sentence 2
Remember that NO PITCH INFORMATION is available from the turn coordinator when establishing a standard-rate turn in instrument conditions.
