CPL Aerodynamics · Mock exam

At the same indicated airspeed (IAS) and angle of attack, an aircraft flying at high altitude compared to sea level will experience:

• A.higher lift and lower drag because the reduced air density decreases profile drag at altitude
• B.The same lift and drag forces in Newtons — IAS reflects the same dynamic pressure
• C.lower lift forces and equal drag force because density is lower even though IAS is maintained
• D.higher drag because the turbulence encountered at altitude increases the form drag coefficient
