RSVM

Question 1

Who initiated a program to asses the feasibility of a RVSM and when?

Answer 1

ICAO in 1982

Question 2

What does RVSM stand for?

Answer 2

Reduced Vertical Separation Minimum

Question 3

The principal benefits which the implementation of RVSM were expected to provide were:

Answer 3

A theoretical doubling of airspace between FL290 and FL410

and

Increased fuel economy

Question 4

What is the new RVSM standard?

Answer 4

1000 ft

Question 5

What did the change from 2000ft minimum to 1000ft minimum allow?

Answer 5

Allows aircraft to safely fly more optimum profiles, gain fuel savings, and increase airspace capacity

Question 6

When was the implementation of the 1000 ft separation standard?

Answer 6

1988

Question 7

Why was the standard historically 1,000 feet from the surface to 29,000 ft (FL290), and 2,000 ft above FL 290?

Answer 7

Because the accuracy of the pressure altimeter decreases with height

Question 8

What caused the standard to be changed?

Answer 8

Over time, Air Data Computers (ADCs) combined with Altimeters have become more accurate and Auto pilots more adept at maintaining a set level

Question 9

How may non-RVSM interact with RVSM?

Answer 9

Non-RVSM approved aircraft may transit through RVSM airspace

Question 10

Who is exempt from the requirement to be RVSM approved?

Answer 10

“State aircraft” such as military, customs and police service

Question 11

What is DRVSM?

Answer 11

Domestic Reduced Vertical Separation Minimum is a procedure that allows controllers to reduce the vertical separation between aircraft from 2,000 ft tc altitudes between 29,000 ft and 41,000 ft

Question 12

What does the DRVSM do?

Answer 12

Increase capacity and save money by allowing more planes to fly preferred altitudes and routes

Question 13

Since the implementation of the new standard, what have declined?

Answer 13

Controller Operational Errors
