<p>An apparatus for indicating to the pilot of an aircraft whether to abort a takeoff because of subnormal acceleration of the aircraft during the takeoff run. The apparatus includes: a chart of the normal takeoff acceleration versus takeoff time for the aircraft for a particular set of conditions; a warning indicator; and means adapted to scan the chart, and responsive to subnormal takeoff acceleration, for actuating the warning indicator. The chart is provided with a conductive area representing the subnormal takeoff acceleration versus takeoff time relationship for the aircraft and particular set of conditions, and the actuating means for the warning indicator includes a contact engageable with such conductive area. Each aircraft is provided with a set of charts covering different airports, different aircraft weights, different wind and barometric pressure conditions, and the like.</p> |
