ACRO [4 records]

Record 1 2017-11-16

English

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

Gyro driven instruments should be caged before aerobatics to avoid tumbling the gyros which action can cause damage to the bearings. In addition, of course, the instrument is useless until the gyro is erected again.

CONT

Gyros that have stops(not many these days and not the case for the gyros in the CJ6) can be damaged by acro when they are running. They should be stopped and preferably caged when doing acro. "Smooth" positive-G acro(no snap or tumbing maneuvers) shouldn’t hurt these gyros if they are powered down even if they are not caged.

OBS

cadge: Appar. variant of cage.

French

Domaine(s)
  • Pilotage et navigation aérienne
  • Instruments et équipement de bord (Constructions aéronautiques)
CONT

Les instruments gyroscopiques devraient toujours être bloqués avant d'effectuer des manœuvres acrobatiques et ce, pour éviter le culbutage qui risque d'endommager les coussinets. L'instrument qui subit un culbutage est rendu tout à fait inutilisable et le reste aussi longtemps que le gyroscope n'a pas repris sa position.

CONT

Blocage de l'axe du gyro («cadged»). L'instrument à l'arrêt est «cagé», c'est-à-dire que le carter est bloqué dans la position qu'il occupe en vol rectiligne horizontal, afin d'éviter toute détérioration des paliers des différents axes.

OBS

Même si le terme «cagé» est employé dans le jargon de certains pilotes, il s'agit d'un calque direct de l'anglais qu'il vaut mieux éviter.

Record 2 2017-11-16

English

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

Gyros that have stops(not many these days and not the case for the gyros in the CJ6) can be damaged by acro [acrobatics] when they are running. They should be stopped and preferably caged when doing acro. "Smooth" positive-G acro(no snap or tumbing maneuvers) shouldn’t hurt these gyros if they are powered down even if they are not caged.... When you subject that spinning gyro to your aircraft's twists and turns during aerobatics you are imparting more force on its bearings than you would were the gyro turned off and not spinning. It is usually bearing wear the trashes a gyro. This problem is especially severe when you are doing advanced aerobatics. It is really hard on the gyro bearings. I would rather have the gyros turned off to make them last longer. That we have caged or uncaged gyros is really irrelevant to the basic physics involved.

Gyro driven instruments should be caged before aerobatics to avoid tumbling the gyros which action can cause damage to the bearings. In addition, of course, the instrument is useless until the gyro is erected again.

Record 4 2005-02-23

English

Subject field(s)
  • Federal Government Bodies and Committees (Canadian)
  • Committees and Boards (Admin.)
OBS

The ACRO is an interdepartmental working level committee that reviews and resolves areas of conflict related to the development of procurement strategies for those contracts included in the annual defence Repair and Overhaul plan that will result in an annual expenditure of at least $500K. Upon completion of its review, the ACRO submits the annual plan for approval to the standing SPAC for Repair and Overhaul(DG level).

Domaine(s)
  • Organismes et comités fédéraux (Gouvernement canadien)
  • Comités et commissions (Admin.)
OBS

Le CCRR est un comité interministériel au niveau de travail qui examine et règle les questions de conflit concernant l'élaboration des stratégies d'achat pour les contrats inclus dans le plan annuel de réparation et de révision de la Défense qui entraîneront une dépense annuelle d'au moins 500 000 $. Une fois son examen terminé, le CCRR soumet le plan annuel, pour le faire approuver, au CCSP permanent responsable de la réparation et de la révision (niveau du DG).
