Quik Trim

Instructions for using the Quik Trim
Weight and Balance Computer

  1. Obtain the Licensed  Empty Weight, C.G. and Moment from the aircraft weight and balance records in the Aircraft Flight Manual or logbook. Enter these values on the face of the QUIK TRIM Computer in the appropriate places provided.
  2. Using the Licensed Empty Weight and C.G. or Moment, locate the point on the face of the QUIK TRIM Computer corresponding to these values and mark with a pencil.
  3. Move the slide to place the zero weight position of the PILOT & FRONT PASS. slot over the point marked above. Establish and mark through the slot a new point opposite the weight of the pilot and front passenger. (NOTE: if the combined weight of the pilot and front passenger exceeds 400 lbs. each may be done separately)
  4. Move the slide to place the zero weight position of the REAR PASS. slot over the point marked above. Establish and mark through the slot a new point opposite the weight of the rear passengers.
  5. Move the slide to place the zero weight position of the BAG. slot over the point marked above. Establish and mark a new point opposite the baggage weight. (NOTE: Do NOT exceed the maximum allowable baggage weight)
  6. Move the slide to place the zero weight position of the FUEL slot over the point marked above. Establish and mark through the slot a new point opposite the fuel quantity in gals. or weight in lbs.

  7. Steps 3, 4, 5, 6 may be done in any order, the last step completed establishes the aircraft Gross Weight, C.G. and Moment.
  8. If the last point marked above for the aircraft gross weight, C.G. and moment lies outside the Weight-C.G. Envelope, move back down the last slot used to the first point within the envelope and mark this point. The weight read directly on the slide opposite the point marked is then the maximum allowable weight which may be carried at that position in the aircraft and remain within the Weight-C.G. Envelope.

It is the responsibility of the aircraft operator to insure that the aircraft is loaded properly.
