Across
  1. 3. What type of circuit do we use to stop ground power paralleling with aircraft power
  2. 4. What are metal battery trays covered in for protection from acid
  3. 5. Used to generate power in a brushless generator
  4. 7. One of the things we monitor batteries for
  5. 10. This is what we use to make sure that a generators output frequency is constant even if the engines change RPM
  6. 11. What type of cut off do we use to connect the generator to the busbar
  7. 13. Failure to excite a generator could be caused by a loss of this
  8. 14. One of the 2 disconnects we have in an IDG system
  9. 15. The number of minutes a battery should be able to supply power for
Down
  1. 1. What type of transformer is used in a Frequency wild system
  2. 2. The type of distribution system in which the generators are never on the same busbar
  3. 3. What voltage does the generator need to be at compared to the busbar before it is put onto that busbar
  4. 6. This is the type of Circuit Breakers (CB) we use on aircraft
  5. 8. The circuit we use in DC parallel generator systems to share the load
  6. 9. The only type of circuit a frequency wild generator can supply power to
  7. 12. If this is low it can cause thermal runaway in a cell
