Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many seconds were in the intervals between landings?
A
60 seconds
B
2 seconds
C
90 seconds
D
120 seconds
Explanation: 

Detailed explanation-1: -As part of the testing of a new aircraft, the manufacturer must demonstrate that all passengers can be evacuated in a short amount of time when an emergency arises-within 90 seconds to be precise. If it doesn’t comply, the aviation authorities won’t approve its safety certification.

Detailed explanation-2: -Current rules say airlines must be able to evacuate passengers within 90 seconds but do not set seat size requirements. The FAA uses tests to determine if shrinking seat sizes and seat pitch on airplanes are safe.

Detailed explanation-3: -The silent review (or 30-second review) is recommended for cabin crew to mentally recall the key aspects of the emergency evacuation procedure while they are seated at their station before each takeoff and landing, and decreases the risk of distraction.

Detailed explanation-4: -A: The standard for vertical separation is now 1, 000 feet. You were right about it being 2, 000 feet until January 20, 2005, when the U.S. implemented Reduced Vertical Separation Minima (RVSM). The pilots were aware of the opposite-direction traffic.
