NIFE BOARD EVALUATION 2026
GUARANTEED PASS ANSWERS GRADED A+
● Density (rho). Answer: Mass per unit volume
● Moment. Answer: A rotational force around a point or axis
● Equilibrium Flight. Answer: Exists when the sum of all forces and the
sum of all moments around the center of gravity are equal to zero.
● Trimmed Flight. Answer: Exists when the sum of all moments around
the center of gravity is equal to zero.
● Temperature vs Altitude. Answer: Decreases linearly with an increase
in altitude at a rate of 2 deg C per 1000 ft until approximately 36,000 ft.
After 36,000 ft, the temperature is constant (isothermal)
● Humidity vs Air density. Answer: As humidity increases, air density
decreases
● General Gas Law. Answer: Sets the relationship between three
properties of air: pressure (P), density (ρ), and temperature (T).
, P=ρRT (R is a constant for any given gas)
● Steady Airflow. Answer: Exists if at every point in the airflow static
pressure, density, temperature, and velocity remain constant over time.
● Continuity equation. Answer: A1V1=A2V2
● Bernoulli's Equation. Answer: Total pressure (Pt) equals static pressure
(Ps) plus dynamic pressure (q)
Pt=Ps+q
q=(1/2)*ρ*(V^2)
● Order of Airspeeds. Answer: Indicated Airspeed (IAS)
Calibrated Airspeed (CAS)
Equivalent Airspeed (EAS)
True Airspeed (TAS)
Ground Speed
Remember "ICE-TG"
● Indicated Airspeed (IAS). Answer: Airspeed read directly from the
airspeed indicator
