Recap:

Consider an aircraft with the following aerodynamic & mission specification: 

• CD0 = 0.0181; k = 1.23; AR = 8.9
• Hold speed = 214 kts at 1500 ft
• Rate of turn = 3.6 deg/s
• Throttle setting 50%

• Hold weight = 0.85 MTOW

Q3 Calculate the required Tsls/MTOW (to 3 d.p.) to satisfy this Hold requirement at a design wing loading (MTOW/Sref) of 5,000 Pa

Consider an aircraft with the following aerodynamic & mission specification: 

• CD0 = 0.0181; k = 1.23; AR = 8.9

• Hold speed = 214 kts at 1500 ft

• Rate of turn = 3.6 deg/s

• Throttle setting 50%

• Hold weight = 0.85 MTOW

Answer the following three questions in turn:

Q1 What is the density of the atmosphere at the hold altitude, in kg/m³

, to 4 d.p.?

Q6 What is the load factor during hold, to 3 d.p.?

Q5 What is the dynamic pressure (at 275 kts, 2000 ft), to the nearest Pascal?

Q2 What is the speed of the aircraft at these conditions, in m/s, to 1 d.p.?

Recap:
