Other:

7) How does the AIRCARE™ Noise Abatement Code define a noise-sensitive area? *

1 point

Other:

12) When a complaint is received, how should it be addressed? *

1 point

a) Contact the complaining party personally and promptly. When you do, avoid being defensive, argumentative or opinionated. Sincerely try to understand the other person’s point of view and avoid hostile confrontations. Sometimes merely listening politely can improve the situation. Evaluate the problem thoroughly and follow through by asking the pilot if he/she was aware of the problem and were procedures followed. Decide if preventative action is possible, complete and Event Notification Form.

b) Tell the person you will get someone to call them but keep putting it off until the complainant forgets the issue

c) Tell them you are not breaking any law whatsoever so there’s nothing they can do about it

Other:

13) Under the Noise Abatement Code operators are required to formulate guidelines that will be used to assist flight crews and flight operations staff to formulate responsible mission profiles. They are also required to consult with local authorities on operational areas and transit routes. A number of other considerations take precedence over these noise abatement requirements. What are they? *

1 point

a) Air Traffic control instructions and flight safety

b) Passenger comfort

c) Transit routes with high scenic values

Other:

14) When low-level operations are to be carried out near populous areas what considerations shall be applied? *

1 point

a) Selecting only a skilled pilot

b) Selecting a time of day and week when the aircraft’s noise will be least intrusive and by selecting the aircraft in the fleet that has the least intrusive noise footprint

c) Selecting the aircraft in the fleet that has had the most recent scheduled inspection

d) Selecting a pilot who most recently completed noise abatement training

Other:

15) An operator is required to have a procedure to ensure that relevant staff:Pass an assessment on noise abatement every three years, and Are assessed on their knowledge of those noise abatement procedures in the aircraft flight manual (where the flight manual details noise abatement procedures) at each annual competency check, andHave noise abatement procedures considered at each annual competency check *

1 point

a) True

b) False

Other:

16) Other Operator Responsibilities are:Educate customers about noise abatement procedures, in order to prevent or minimize conflicts between their expectations and company policy, andEnsure that in areas where a User Group has been established under CAA and Airways protocols, the operator maintains membership of that User Group and takes an active part in its activities, andEnsure that the procedures detailed in the Fly Neighbourly Guide result in continual improvement in respect to the operator’s noise footprint *

1 point

a) True

b) False

Other:

17) Other Operator ResponsibilitiesEnsure that any new aircraft purchased has a smaller noise footprint than existing types *

1 point

a) True

b) False

Other:

18) The Noise Abatement Code makes some recommendations to operators about best practice. Some are: Establish a practice of promoting both the safety record and the benefits of aircraft use to the public at large to improve public acceptance of aircraft, andWhere possible, when operations below 500ft AGL are anticipated, arrange notification to all affected parties near the proposed flight path *

1 point

a) True

b) False

Other:

19) The Noise Abatement Code also requires ALL low-level operations to be notified to affected parties *

Other:

24) Doppler-effect on aircraft noise is: *

1 point

a) The warbling sound of engine exhaust

b) Not a factor with aircraft noise

Other:

25) Noise characteristics: *

1 point

a) The noise level in decibels alone dictates the obtrusiveness and annoyance of a sound.

b) The frequency and type of noise, even though of similar decibel noise level, is a significant factor in noise annoyance

Other:

26) Propellers: *

1 point

a) Prop noise can be decreased by making the blades thicker

b) A multi bladed propeller with shorter blades will generate less noise.

Other:

27) Orbiting. *

1 point

a) An aircraft orbiting emits a continuous sound to a listener at a fixed point some distance away

b) An aircraft orbiting emits an apparent higher frequency sound on the phase of the orbit towards a listener at a fixed point some distance away.

c) An aircraft orbiting emits an apparent lower frequency sound on the phase of the orbit towards a listener at a fixed point some distance away.

Other:

28) Propeller noise: *

1 point

a) Emanates from the tips alone

b) Is a product of the energy of the pulses of air thrown off by the blades together with propeller tip speed being a significant factor that can be reduced by the pilot

1 point

a) Air movement due to wind does not affect sound propagation.

b) Flying up wind of sensitive areas will ensure the minimum noise annoyance

30) Altitude: *

1 point

a) Fly over height is significant for helicopters but not fixed wing

b) Fly over height is a critical factor in perceived aircraft noise as heard at ground level. As a general rule, ground observers view noise as halving with each doubling of distance from the source.
