Parameter	Symbol	Unit	Definiton
TLARs
Aircraft Classification Number	ACN		The ACN number expresses the effect of individual aircraft on different pavements. The pavement type can be either flexible or rigid, with the sub-categories A = High Strength, B = Medium Strength, C = Low Strength, and D = Ultra Low Strength
Geometry
Wing area	Sref	m2	exposed wing area plus area of rectangle inside the fuselage between leading and trailing edges at the root (wing-fuselage intersection).
Accommodation
LD3-45			standard designation of ULD
Unit load device	ULD		pallet or container used to load luggage, freight and mail
Mass per PAX		kg/PAX	Average mass = 200 lb/PAX = 90.72 kg/PAX (incl. luggage)
Masses
Operating weight empty	OWE	kg	= MWE + Operator Items
Manufacturer’s weight empty	MWE	kg	= Masses structure + propulsion + systems + furnishings group
Propulsion
Sea-level static thrust	SLST	kN	Flat rated engine thrust at Mach 0, sea level and ISA+15
Equivalent thrust		kN	1.25 &sdot go-around thrust at Mach 0.25, sea-level, ISA+15
Performance and mission simulation
Range	R	NM	in the mission simulation the range is defined as the distance from the point of brake release (after taxiing at the origin airport) to the point of touch down at the destination airport (excluding the landing distance).
Costs
Load factor	LF	-	Mission payload / max. payload
