Section 19 - Weight & Balance Flashcards
What is the maximum baggage compartment weight and floor loading limitation?
65 lbs per square foot, 2000 lbs maximum
What is the formula for finding the GIV CG in inches aft of the reference datum?
Total Moment divided by Total Weight = Arm multiplied by 10,000
What is the definition of Basic Operating Weight (BOW)?
Standard aircraft items + crew
What is the definition of Zero Fuel Weight (ZFW)?
BOW + crew + passengers + cargo
What is ramp weight?
Zero fuel weight + fuel
What is the center of gravity?
CG is a point about which the aircraft would balance, normally measured in inches aft of the reference datum or% MAC
What is MAC?
Mean aerodynamic chord is the distance from LEMAC to TEMAC
What is LEMAC & TEMAC?
Leading edge and trailing edge of the mean aerodynamic chord
What is the reference datum {reference data line)?
A reference point on an airframe from which the horizontal arm can be measured
What is the horizontal arm?
Distance along the longitudinal axis from the RDL to the CG of an item, usually measured in inches to a fuselage station
What is a fuselage station?
The horizontal distance ( called an ARM, usually expressed in inches) from the RDL used in a formula with weight to determine moment
What is a moment in reference to the weight & balance formula?
The product of a weight and its arm, expressed in inch-pounds. Gulfstream indexes the number and divides by 10,000 for simplicity in calculations
Why do we calculate the zero fuel CG in % MAC?
To determine the correct elevator trim setting for takeoff using the trim table
What does the correct elevator trim setting provide for takeoff?
Provides a “no additional elevator trim” setting in the unlikely event that an engine failure occurs on takeoff
What is the maximum zero fuel weight?
46,500 lbs (non-SP) or 49,000 lbs (SP)
