PISTON-TWIN MISSION QUESTIONS
Guide: https://yenra.com/piston-twin/
Prepared September 30, 2026. An inquiry worksheet, not a flight plan or performance calculation.

Instructions: Describe a representative mission and give this record to the qualified operator, pilot or adviser. Use one unit system and label all weights. Actual loading, fuel, runway and engine-out assessments require the aircraft's approved data.

Date / purpose (charter, training or ownership inquiry):
Exact aircraft model / registration / serial number:
Origin and destination airports / dates / required arrival:
Acceptable stops and alternative transport:
Pilot and passenger count:
Occupant weights with units and source:
Baggage weights/dimensions and special requirements:
Cabin layout, boarding access and baggage stowage confirmed by:
Aircraft-specific weight-and-balance record reference:
Person responsible for approved load and fuel assessment:
Range source, power/altitude, load and reserve assumptions:
Runway and weather assessment responsibility:
One-engine-inoperative performance questions for instructor/operator:
Records, inspection, parts and support questions:
Training needed / provider:
Unresolved item / document needed / responsible person:

Fictional arithmetic only: 1,400 lb useful load - 600 lb fuel = 800 lb remaining. Four occupants x 180 lb + 100 lb bags = 820 lb, 20 lb above that allowance. These invented figures establish neither center of gravity nor flight suitability. Have qualified personnel resolve the complete load and mission; do not reduce fuel based on this worksheet.
