Course content
1. Center of gravity and weight and balance limits - significance with respect to aircraft stability. 2. Loads - weights, operational loads, payloads and commercial loads. 3. Aircraft weight checks - procedure, aircraft reweigh requirements, equipment lists. 4. Effects of overload - higher take-off, safe and stall speeds, effect on range and endurance, reduced performance with the engine off, possible damage to the structure in extreme cases. 5. Calculations of the center of mass - reference plane, moment arm, moment, expressed in percentages of the central aerodynamic chord. 6. Securing the load - the importance of appropriate lashing, the effect of displacement, loading area, load, technical means. 7. Basic definition - regulatory base, CS 23 and CS 25 airworthiness, operational regulations, performance classes. 8. Takeoff and climb - definitions, speeds, variables, climb, access - theoretical and practical. 9. Travel section of the flight - balance of forces and moments, required thrust and power, characteristic modes, range and endurance. 10. Descent/gliding flight, landing - flight parameters, speed polar, gliding flight, landing. 11. Single-engine performance class B airplanes - take-off, performance, climb gradient, approach, cruise mode, maximum speed, range, engine cut-out, endurance, landing, climb gradient after missed landing. 12. Performance Class B multi-engine airplanes - take-off, performance, climb gradient, approach, cruise mode, maximum speed, range, engine cut-out, endurance, landing, climb gradient after missed landing. 13. Performance class A airplanes - take-off, performance, climb gradient, approach, cruise mode, maximum speed, range, engine shutdown, endurance, landing, climb gradient after missed landing, drift-down, ETOPS.

Learning activities and teaching methods
Monologic (reading, lecture, briefing)
  • Home preparation for classes - 24 hours per semester
  • Contact teaching - 52 hours per semester
  • Preparation for an exam - 44 hours per semester
  • Preparation for a credit (assessment) - 30 hours per semester
Learning outcomes
The aim of the course is to familiarize students with issues and procedures in calculating the weight, balance and performance of aircraft.
After completing the course, the student will be able to calculate the center of gravity of the aircraft and will understand the performance of the aircraft and what affects the performance.
Prerequisites
A basic knowledge of air transport and aircraft construction is assumed.

Assessment methods and criteria
Oral examination, Written examination

In order to successfully complete the course, it is necessary to know the subject matter discussed in the lectures.
