FDAI (with housing removed)
  • Flight Director Attitude Indicator (FDAI) with housing removed.
  • Indicator mounts a ball with three axes of rotation, showing the spacecraft attitude in yaw, roll and pitch.
  • Short needles on the outer scales indicate attitude rates.
  • Longer needles over the indicator face show commanded attitudes from the spacecraft guidance system.
  • Red circles centered at yaw 0 and 180 degree poles indicate where the inertial guidance gimbals are in danger of locking (gimbals from two axes aligning with each other) causing loss of attitude reference.
