1. A pitch command display method comprising:
- identifying an aircraft touchdown comprising determining that landing gear of an aircraft has touched a runway,identifying a first value representing an actual aircraft pitch reduction rate,identifying a second value representing a target aircraft pitch reduction rate,determining a difference between the first value and the second value, anddisplaying a pitch command when an aircraft touchdown is identified and the difference between the first value and second value is greater than a threshold amount.

Abstract
A pitch command display method includes identifying touchdown of an aircraft, identifying a first value representing an actual pitch reduction rate of the aircraft, identifying a second value representing a target pitch reduction rate of the aircraft, determining a difference between the first value and the second value, and displaying a pitch command when the difference between the first value and second value is greater than a threshold amount and the aircraft has touched down.
