PITCH DOWN ANGLE [7 records]

Subject field(s)
  • Flight Controls (Aeroindustry)
  • Flight Instruments and Equipment (Aeroindustry)
  • Aircraft Piloting and Navigation
CONT

The command bars move up for a climb or down for descent, and roll left or right to provide lateral guidance. They display the computed angle of bank for standard-rate turns to enable the pilot to reach and fly a selected heading or track. The bars also show pitch commands that allow the pilot to capture and fly an ILS [instrument landing system] glide slope, a preselected pitch attitude, or maintain a selected barometric altitude.

CONT

To recover from the microburst, the crew apply maximum power and pitch up toward an angle that can attain 15 degrees. The inertial acceleration(acceleration in reference to the ground, as opposed to acceleration within the airmass) experienced by the pilots, combined with the unstable attitude of the aircraft may cause a dangerous illusion. The pilots may believe that the aircraft has reached a very high excess energy and thus, try to pitch down or reduce the engine power. In reality, the aircraft performance is still low as it penetrates the energy-reducing downdraft and tailwind components of the microburst.

CONT

V-bar : Flight Director Indicator... The V-bar command indicator is a pair of yellow, wedge-shaped V-bars that move up or down to command a climb or descent, and roll left or right to command a bank. The flight director system commands the V-bars to capture and track the selected heading or radio signals; or to maintain a desired pitch angle, glidepath, or an optimum speed during SC(speed command) operation. To satisfy the commands, the aircraft is maneuvered so that the airplane symbol is flown into the V-bars until the two are aligned. Input signals to the V-bars depend upon the mode of operation. The V-bars are biased from view by the instrument failure warning system; when loss of signal occurs, or sensing circuits fail that are associated with the selected mode of operation. They are also out of view when the mode selector control is in the OFF position.

L'indicateur HZ-4 [horizon directeur de vol] assume deux fonctions. Il réalise la combinaison d'un horizon artificiel et d'un indicateur de tendances du type "zero reader". [...] Les deux barres, verticales et horizontale, sont les barres de tendance liées au calculateur de vol. La barre verticale reçoit les informations du canal de direction, la barre horizontale celles fournies par le canal de profondeur.

CONT

[...], dès que l'avion ne sera plus dans la situation requise, les 2 barres ou repères, appelés BARRES ou REPÈRES DE TENDANCES ne seront plus dans une position médiane vis à vis du cadran de l'indicateur.

OBS

barre de tendance : terme accepté par le Comité d'étude de la terminologie des cartes de travail du DC-9.

ACMRI has four basic sub-systems. First is a sidewinder-shaped external pod which attaches to the aircraft's missile mounting rack and contains instrumentation independent of the aircraft's own systems to measure altitude, airspeed, Mach number, angle of attack and sideslip, plus a compact inertial sensor which measures pitch, roll, heading and acceleration/deceleration. The instrumentation package... also contains a transponder-like radio link which transmits all this information down on command from the second sub-system, the ground tracking station network... the third sub-system-the Control and Computation facility... precise aircraft position determination, and data formatting prior to reaching the fourth... sub-system... the Display and Debriefing Sub-system.

With the German government research establishment DFVLR, Dornier is developing an Open-Loop Gust Alleviation(OLGA) system. Gusts are sensed by an angle of attack vane at the nose, pitch rate gyro and vertical accelerometer : gust responses are dampened by moving both ailerons up or down simultaneously in association with the elevator.
