Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A wing with very high aspect ratio (in comparison with low aspect ratio wing) will have.
A
Increased drag at high angles of attack
B
A low stall speed
C
Poor control qualities at low airspeeds
D
None of the above
Explanation: 

Detailed explanation-1: -The larger the wingtip part is relative to the whole wing, the lower the maximum lift will be. Given the same wing area and mass, a wing with a higher aspect ratio will produce a lower stall speed.

Detailed explanation-2: -A high aspect ratio indicates long, narrow wings. A low aspect ratio indicates short, wide wings. Generally, high aspect ratio wings give slightly more lift and enable sustained, endurance flight, while low aspect ratio wings are best for swift manoeuvrability.

Detailed explanation-3: -The wing aspect ratio, which represents the ratio of the wing length to the average wing cord, affects the lift force and the drag force that creates resistance to the movement of the wing. That is why it is an important parameter that determines the performance of the wing and affects the stall character of the wing.

Detailed explanation-4: -A high aspect ratio wing is typically longer, thinner, faster, lower drag but lower lift; a low aspect ratio wing is shorter, fatter, and has higher lift but also higher drag. High aspect ratio wings are often used in speed-oriented disciplines such as windfoil slalom and course racing, and Formula Kite racing.

Detailed explanation-5: -Second, they can’t hold as much fuel for the same reason: less space. And third, if large aircraft had extremely high aspect ratio wings, they would be nearly impossible to maneuver around airports. Their wings would hang over taxiways and runways, and you couldn’t park them anywhere near each other.
