Question 1

What is Basic Empty Weight?
What is Standard Empty Weight?
How do you define the ARM?
What is that on the Archer?

Answer 1

BEW: standard empty weight, optional equipment, unusable fuel and all operating fluids
SEM: airframe, engine, unremovable parts
baggage compartment limit: 200lbs
MTOW: max to weight
arm&moment:
Arm. The horizontal distance from the reference datum to an item’s center of gravity. Moment. A force causing something to rotate, equal to an item’s weight times its arm.

Question 2

Let’s move into the bottom, we know our elevation. How did you calculate PA?
How do you get DA?
What does the ISA deviation mean?

Answer 2

Pressure Altitude = current - standard pressure) x 1000 + elevation
Density Altitude in Feet = Pressure Altitude in Feet + (120 x (OAT°C – ISA Temperature °C)

Pressure Altitude is the indicated altitude when an altimeter is set to 29.92 in Hg

Density Altitude is formally defined as “pressure altitude corrected for nonstandard temperature variations
(OAT-ISA temp) x 120 + PA

ISA deviation refers to the difference between the actual atmospheric conditions and the standard atmosphere.
