Air Traffic Flow And Capacity Management

Question 1

Define Air Traffic Flow Management

Answer 1

A service established with the objective of contributing to a safe, orderly and expeditious flow of air traffic ensuring that ATC capacity is utilised to the maximum extent possible, and that traffic volume is compatible with the capacities declared by the appropriateATS authority.

Question 2

Define Air Traffic Flow and Capacity Management

Answer 9

Yes

Question 10

What is Airspace Management (ASM)?

2 things

Answer 10

A planning function (SHORT TERM)
Objective of maximising available airspace by dynamic time sharing segregation of airspace (Short Term)

(FUTURE) also a strategic function

Question 11

Strategic planning should be carried out in conjunction with ATC and a/c operators (AO)
True or False?

Answer 11

True

Question 12

Strategic planning should examine the demand of forthcoming season, assessing where and when demand is likely to exceed the available ATC. Capacity and taking steps to resolve imbalance by:
4 things

Answer 12

1) Arranging with ATC authority adequate capacity at the required place/time
2) Re-routing certain traffic flows (traffic orientation)
3) Scheduling/rescheduling flights
4) Identifying the need to tactical ATFM measures

Question 13

Pre-tactical planning should entail fine tuning of the strategic plan in light of updated demand data. During this phase 3 things should be done/considered.

Answer 13

1) Certain Traffic flows may be re-routed.
2) off load routes may be coordinated.
3) Tactical measures will be decided upon.

Pre-tactical Flow Management Analysis is it planed events will look at events such as :

3 things

Answer 15

Military training

Air shows

AD works

Question 16

Tactical AFTM Operations should consist of:

2 things

Answer 16

A) Executing: the agreed tactical measures in order to provide a reduced and even flow of traffic. Where demand would otherwise have exceeded capacity.

B) Monitoring: Evolution it Air Traffic situation to ensure ATFM measures applied are having the desired effect. And take remedial action when long delays are reported. Includes re-routing. To utilise available ATC capacity to maximum extent

Question 17

When all else fails…restrict movement. Done by Constraint Airborne capacity with CTOT (slots) how are skits communicated?

Answer 17

Via AFTN

Question 18

What do slots aim to do?

Answer 19

5

10

Question 20

ATFCM endeavours to make Airspace n AD capacity meet traffic demand when these endeavour are exhausted make demand meet the max available capacity
This may result in flow measures which allocate individual a/c departure times (CTOT) to combat bottlenecks and reduced safety risks as much as possible.
