Aviation and Indian History Quiz

This refers to a historical discussion during partition negotiations. The figure of Rs. 55 crores is mentioned in some historical accounts related to partition settlement discussions. The question references the financial negotiations surrounding the creation of Pakistan in 1947.

Hyderabad is also historically known as 'Namaalli' or 'Namapally', referring to the area around the Nampally railway station and Nampally locality. This is one of Hyderabad's older neighborhoods. The other options are other major Andhra/Telangana cities.

Lal Krishna Advani was born on November 8, 1927, in Karachi, which was then part of British India and is now in Pakistan. Many prominent Indian leaders of that generation were born in cities that became part of Pakistan after partition. He moved to India after partition.

Pingali Venkayya designed the Indian National Flag. He was a freedom fighter from Andhra Pradesh who designed the flag in 1921. The design was later modified by the Indian National Congress, but Venkayya is credited as the flag's designer. His birthday (August 2) is observed as 'National Flag Day' in some states.

In single-engine airplanes, torque effect is greatest at low airspeed, high power settings, and high angles of attack. At low speeds with high power and high AOA, the propeller's torque creates significant left-turning tendency in American-engine aircraft that cannot be overcome by airflow over the vertical stabilizer. High airspeeds (options C, D) provide more rudder effectiveness to counteract torque. Low power settings (option B) reduce torque effect. Answer A correctly identifies the conditions where torque is most pronounced.

Air traffic control light signals: flashing green (option C) means 'cleared to taxi' for aircraft on the ground. Steady green (B) is 'cleared for takeoff' in flight. Flashing white (A) means 'return to starting point' on ground. Steady white (D) is 'ground vehicle - move clear of runway/taxiway'. Answer C is correct - flashing green from the tower gives permission to taxi on the ground. This is standard aviation light signal procedure.

Altimeter setting adjusts the barometric pressure scale so the altimeter indicates true altitude at field elevation. True altitude is the actual height above mean sea level under current atmospheric conditions. Answer B is correct - the alteter setting calibrates the instrument to read true altitude at the airport's elevation. Absolute altitude (A) is height above ground level. Calibrated altitude (C) is indicated altitude corrected for instrument error. Answer D describes pressure altitude, not the purpose of altimeter setting.

Ground effect reduces induced drag most significantly when the aircraft is within one wingspan of the surface. This reduction in drag causes the aircraft to 'float' or require less power to maintain lift during the landing flare. Being higher than one wingspan (option B) produces minimal ground effect, while angle of attack changes (C, D) are not the primary factor in ground effect floating.

In a spin, BOTH wings exceed the critical angle of attack and are stalled. The autorotation that characterizes a spin occurs because one wing is more deeply stalled than the other (the outside wing in a left spin has a higher angle of attack), not because only one wing is stalled. If only one wing were stalled, the aircraft would be in a spiral dive, not a spin.
