<p>An aircraft performance instrument having a first indicator (38) which represents the line of level flight of the aircraft and a second indicator (40) representative of the maximum permissible angle of attack of the aircraft. The separation between the two indicators is a measure of the take-off performance capability of the aircraft. It also represents degraded performance due to a wind shear condition thereby providing the pilot with guidance as to how to respond to wind shear.</p> |
