answers of unseen passage 'Gyrocopters' for class 9
a hybrid between helicopters and gliders, gyrocopters are set to make their debut in India in the next couple of months. this smaller, lighter and quieter version of the chopper will perhaps be the answer to the country's traffic problems. the catch? they'll cost approximately the same as a luxury car -- a stellar Rs. 30 Lakh onwards .
world over, gyrocopters are used for border security, coastal area surveillance, road petrolling and agriculture crop spraying. according to rishabh Mehta, managing director of the company that's bringing gyrocopters in India, "while individuals can also buy them, it could take up to a year for licensing and security clearance since the government has tightened aviation rules post 26/11."
so what makes a gyrocopters so exciting? for starters, they can fly very low, only a few centimeters above the ground at a very low speed, about 30 know unlike a helicopter which cannot fly low, and slow at the same time. gyrocopters are also much less expensive and need very little landing space unlike a glider. like a helicopter, the gyro needs an engine for the initial thrust. later, the engine cuts off and it's the direction of the wind that makes it sail like a glider. however, unlike a helicopter, it cannot take-off and land vertically.
meanwhile, the directorate general of civil aviation has decided to formulate a separate category for gyrocopters in India. "we don't want them to operate in a city with high population, or around a VIP or defence area," says a DGCA official.

Questions :-
A. What are gyrocopters? How can they help solve the country's traffic problems?
Gyrocopters are a hybrid between helicopters and gliders and are seen to be the future solutions for the country’s traffic problem. Expected to make their debut in India in the next couple of months, the gyrocopters can fly very low just a few centimeters above the ground at a very low speed, unlike the helicopter which cannot fly low, and slow at the same time. The gyrocopters are less expensive and need very little landing space unlike a glider.
B. What are some of the key areas where gyrocopters can be very useful?
Gyrocopters can be very useful for coastal area surveillance, road patrolling agriculture crop spraying and most importantly, border security.
C. List any two advantages that gyrocopters have over helicopters?
The two advantages that the gyrocopters have over helicopters are:
1. The gyrocopters can fly very low just a few centimeters above the ground
2. The gyrocopters can fly at a very low speed
D. In what sense is a gyrocopter similar to a helicopter?
The similarity between the helicopter and the gyrocopter is that both need an engine for their initial thrust.
E. What does the DGCA want to formulate a separate category for gyrocopters in India?
The DGCA wants to formulate a separate category for gyrocopters in India as they don’t want them to operate in a city with high population, or around a VIP or Defence area.
F. How do the rotors of a gyrocopter work?
The rotors of a gyrocopter work by changing the angle of the air as the air moves upwards and backwards relative to the rotor blade.
G. What makes the gyrocopter the safest method of flying?
They fly low and need less landing space.
H. Find 2 words in paragraph 2 of the passage that can be used in the sense "to guard something".
