Study Notes
Here are the study notes for the text:
Form F
- Form F is used to calculate the weight and balance of an aircraft.
- The form is used for tactical aircraft and is completed by a qualified weight and balance technician.
Completion of Form F
- The form is completed in a specific order, with each section building on the previous one.
- The following sections are completed:
- Ref 1: Aircraft basic weight and simplified moment/index.
- Ref 2: Oil and fuel quantities.
- Ref 3: Non-expendable items (e.g. crew, baggage, cargo).
- Ref 4: Operating weight.
- Ref 5: Ammunition.
- Ref 6: Ordnance.
- Ref 7: Fuel on board at takeoff.
- Ref 8: Miscellaneous items.
- Ref 9: Takeoff condition (uncorrected).
- Ref 10: Takeoff CG (uncorrected).
- Ref 11: Corrections (if necessary).
- Ref 12: Takeoff condition (corrected).
- Ref 13: Takeoff CG (corrected).
- Ref 14: Total takeoff fuel and expendable items.
- Ref 15: Estimated landing fuel.
- Ref 16: Estimated landing condition.
- Ref 17: Estimated landing CG.
Checks and Limitations
- The weight and balance of the aircraft are checked against the allowable gross weight and CG limits.
- The calculated CG is checked to ensure it is within the permissible limits.
- If the calculated CG is not within the permissible limits, changes to the load and/or fuel are required.
Signatures and Approval
- The following signatures are required on the Form F:
- Computed by: The qualified weight and balance technician who completed the form.
- Weight and balance authority: The signature is optional and dependent on the organizational structure.
- Pilot: The name of the pilot who will operate the aircraft.
Locally Generated Forms
- Locally generated forms may be used to assist with weight and balance tasks.
- However, these forms must be approved by the organization responsible for the aircraft's engineering before they can be used.
- Any changes to the forms must have prior approval before they can be incorporated.
This quiz is about calculating the total weight and simplified moment/index of cargo items. It involves understanding how to enter and total the weights of large cargo items, standard passenger loads, and items loaded on pallets.
