05 ENR Control

Question 1

Would an IFR flight heading in an easterly direction below FL290 be at an odd or even level?

Answer 1

Odd

Question 2

When operating within block levels may a pilot operate at any of the levels within the block?

Answer 2

YES

Question 3

In what level band is RVSM airspace?

Answer 3

FL290-FL410

RVSM - Reduced Vertical Separation Minima.
If the Aircraft has RVSM-capable aids, 1000 feet can still remain as vertical separation limit until FL410 (420 too high)

Question 4

What are the minimum mandatory equipment requirements for RVSM to operate?

Answer 4

The minimum equipment fit is:
(a) two independent altitude measurement systems. Each system should comprise of the following elements:
(i) cross-coupled static source/system, provided with ice protection if located in areas subject to ice accretion;
(ii) equipment for measuring static pressure sensed by the static source, converting it to pressure altitude and displaying the pressure altitude to the flight crew;
(iii) equipment for providing a digitally coded signal corresponding to the displayed pressure altitude, for automatic altitude reporting purposes;
(iv) SSEC, if needed to meet the performance requirements of sections 8.3.3, 8.3.4, or 8.3.6(a) and (b) above, as appropriate; and
(v) the equipment fit should provide reference signals for automatic control and alerting at selected altitude. These signals should preferably be derived from an altitude measurement system meeting the full requirements of this document, but must in all cases enable the requirements of sections 9.2.6 and 9.3 to be met.
(b) one Secondary Surveillance Radar altitude reporting transponder. If only one is fitted, it should have the capability for switching to operate from either altitude measurement system;
(c) an altitude alert system; and
(d) an automatic altitude control system

Question 5

Provide three uses for information provided by the surveillance system and presented on the Air Situation Display.

Answer 5

a) provide surveillance services to:
i) improve airspace utilisation;
ii) reduce delays;
iii) provide for direct routings;
iv) optimise flight profiles; and
v) enhance safety;
b) provide vectoring to:
i) departing aircraft to facilitate an expeditious and efficient departure flow
and expedite climb to cruise level;
ii) aircraft to prevent potential conflicts;
iii) arriving aircraft to establish an expeditious and efficient approach
sequence; and
iv) assist pilot navigation;
c) provide separation and maintain normal traffic flow when an aircraft
experiences communication failure within the area of coverage;
d) maintain flight path monitoring of air traffic; and
e) maintain a watch on the progress of air traffic in order to provide:
i) improved position information regarding aircraft under control;
ii) supplementary information regarding other traffic; and
iii) information regarding any significant deviations by aircraft from the
terms of their respective clearances.

Question 5

What symbol in item 10 of a flight plan indicates that an aircraft has RVSM approval?

Answer 5

W

Question 6

State 4 reasons a controller may use vectoring?

Answer 6

i) departing aircraft to facilitate an expeditious and efficient departure flow
and expedite climb to cruise level;
ii) aircraft to prevent potential conflicts;
iii) arriving aircraft to establish an expeditious and efficient approach
sequence; and
iv) assist pilot navigation;

Question 7

When an aircraft experiences communication failure how can surveillance systems help?

Answer 7

Provide separation and maintain normal traffic flow when an aircraft
experiences communication failure within the area of coverage.
