# §25.1587. Performance information.

- (a) Each Airplane Flight Manual must contain information to permit conversion of the indicated temperature to free air temperature if other than a free air temperature indicator is used to comply with the requirements of [§ 25.1303(a)(1)](/cfr/14/25.1303.md?p=a-1).
- (b) Each Airplane Flight Manual must contain the performance information computed under the applicable provisions of this part (including §§ [25.115](/cfr/14/25.115.md), [25.123](/cfr/14/25.123.md), and [25.125](/cfr/14/25.125.md) for the weights, altitudes, temperatures, wind components, and runway gradients, as applicable) within the operational limits of the airplane, and must contain the following:
  - (1) In each case, the conditions of power, configuration, and speeds, and the procedures for handling the airplane and any system having a significant effect on the performance information.
  - (2) VSR determined in accordance with [§ 25.103](/cfr/14/25.103.md).
  - (3) The following performance information (determined by extrapolation and computed for the range of weights between the maximum landing weight and the maximum takeoff weight):
    - (i) **Climb in the landing configuration.**
    - (ii) **Climb in the approach configuration.**
    - (iii) **Landing distance.**
  - (4) Procedures established under § [25.101(f)](/cfr/14/25.101.md?p=f) and [(g)](/cfr/14/25.101.md?p=g) that are related to the limitations and information required by [§ 25.1533](/cfr/14/25.1533.md) and by this [paragraph (b)](#b) in the form of guidance material, including any relevant limitations or information.
  - (5) **An explanation of significant or unusual flight or ground handling characteristics of the airplane.**
  - (6) **Corrections to indicated values of airspeed, altitude, and outside air temperature.**
  - (7) An explanation of operational landing runway length factors included in the presentation of the landing distance, if appropriate.
