AFH 4 EXAM QUESTIONS AND
ANSWERS GRADED A+ 2025/2026
What is energy management in aviation? - ANS The process of planning, monitoring, and
controlling altitude and airspeed targets in relation to the airplane's energy state.
What are the three main objectives of energy management? - ANS 1. Attain and maintain
desired vertical flightpath-airspeed profiles. 2. Detect, correct, and prevent unintentional
altitude-airspeed deviations. 3. Prevent irreversible deceleration and/or sink rate leading to a
crash.
Why is energy management critical for new pilots? - ANS It is essential for achieving and
maintaining desired vertical flight path and airspeed profiles and for transitioning between
different flight profiles.
What are the three common types of fatal accidents related to energy mismanagement? -
ANS 1. Loss of control in-flight (LOC-I). 2. Controlled flight into terrain (CFIT). 3. Approach-
and-landing accidents.
What is the formula for potential energy in aviation? - ANS Potential energy is expressed as
mgh, where m is mass, g is the gravitational constant, and h is height (altitude).
What is the formula for kinetic energy in aviation? - ANS Kinetic energy is expressed as ½
mV², where m is mass and V is velocity (airspeed).

,How is the total mechanical energy of an airplane expressed? - ANS Total mechanical energy
is the sum of potential energy and kinetic energy: mgh + ½ mV².
What does it mean for an airplane to be an 'open' energy system? - ANS It means the
airplane can gain energy from sources like fuel and lose energy to the environment, allowing for
energy to be added or removed from its total mechanical energy.
What determines the energy state of an airplane? - ANS The total amount and distribution of
energy stored as altitude and airspeed.
What is the difference between indicated altitude and height above ground level? -
ANS Indicated altitude is based on the height above a fixed reference point (mean sea level),
while height above ground level varies with terrain elevation.
What factors affect changes in indicated altitude and airspeed? - ANS Changes are attained
through pilot control inputs, while AGL-altitude and groundspeed are affected by external
factors like terrain and wind.
What happens when thrust exceeds drag during flight? - ANS The airplane's total mechanical
energy increases, allowing the pilot to store surplus energy as increased altitude or airspeed.
What occurs when drag exceeds thrust? - ANS The airplane's total mechanical energy
decreases, and the pilot can use stored energy to descend at a constant airspeed or slow down
while maintaining altitude.
What does it mean when T - D = 0? - ANS All thrust is spent on drag, and the total amount of
mechanical energy remains constant as the airplane maintains a constant altitude and airspeed.

, How does energy exchange occur between altitude and airspeed? - ANS When a pilot trades
airspeed for altitude, as altitude increases, airspeed decreases, and vice versa.
What is the significance of balancing energy management? - ANS Managing energy is crucial
as it involves continuously gaining energy from thrust and losing energy through drag during
flight.
What is the pilot's frame of reference for managing energy state? - ANS It is airplane-centric,
based on indicated altitude and indicated airspeed rather than height above ground or
groundspeed.
What role does the pilot's control inputs play in energy management? - ANS Control inputs
determine the airplane's ability to climb/descend or accelerate/decelerate, affecting energy
management.
What is the relationship between thrust and drag in energy management? - ANS Thrust adds
energy to the airplane while drag removes energy, and their balance determines the airplane's
energy state.
What is a constant airspeed climb? - ANS A flight profile where the airplane climbs while
maintaining a constant airspeed.
What is the importance of a mental model of the airplane as an energy system for pilots? -
ANS It helps pilots effectively coordinate control inputs to achieve and maintain altitude and
airspeed targets.
What should pilots do to minimize risks associated with terrain or wind? - ANS Pilots should
manipulate the airplane's energy state to maximize energy gains and minimize energy losses.
