- Describe the effect of the fuselage, the powerplant, engine nacelles and propeller slipstream on longitudinal static stability
- Define and calculate “ elevator hinge moment coefficient”
- Calculate the elevator angle necessary to maintain trimmed flight and discuss the effect of moving the aircraft center of gravity on aircraft stability and the elevator deflection angle
- Solve aircraft manoeuvre (steady level coordinated turn) problems
- Explain the relationship between load factor, stall speed, angle of bank, speed of turn and the radius of turn
- Calculate range and endurance for a typical piston engine and jet engine powered aircraft
- Describe “Specific Fuel Consumption” for piston engine (SFC) and jet engine (TSFC)
- Describe the conditions for maximum endurance and range for piston engine and jet engine aircraft
- Define terms such as speed of sound, Mach number, Mach line, Mach angle, normal shock, oblique shock, critical Mach number, shock attachment Mach number
- Define “isentropic” and “adiabatic” flow
- Do calculations using the oblique shock chart
- Describe the variation of CL, CD and total drag of an aerofoil across the transonic range
- Explain the movement of centre of pressure across the transonic range
- Describe the advantages and disadvantages of swept wings relative to high speed flight
- Describe the area rule for minimising transonic drag
- Explain why trim drag increases on a conventional aircraft in high speed flight
- Calculate CL and CD for simple supersonic aerofoil sections (Ackeret Linearised Theory)
- Describe leading edge characteristics for subsonic and supersonic aerofoil
- Describe common features of supersonic wings
