A & B Cert Rules

(To download a pdf copy of this page plus the schedules for the aerobatic and helicopter A and B tests click here)

The main aim of the A and B Achievement Schemes is to encourage model flyers to reach a minimum standard of flying ability and safety and to promote a desire for personal betterment in achieving as high a standard as possible in their flying.

Two R/C power categories are covered:

M.A.C.I. will not charge any fees for any A or B certificate examination.

There shall be 2 achievement levels for R/C powered model flying:

  1. The A Certificate level
  2. The B Certificate level

The A certificate shall generally be an acknowledgement of a person's capability to control an R/C model in a safe manner in normal circumstances without the assistance of a supervising instructor.

The B certificate shall generally be an acknowledgement of a person's capability to control an R/C model in such a manner that he/she is able to fly at a public display.

MACI do not guarantee any capability or the performance of any individual as a result of the issue of an achievement certificate. The certificate only states that the candidate achieved the required standard during the test.

The scheme will be administered by a MACI sub committee consisting of the relevant discipline secretaries at that time and one appointed member of the Executive Council. The sub committee shall elect from its members a Chairperson who shall oversee its activities and report back to the MACI Council. The committee shall ensure an adequate number of Examiners will be available during the year and will also arrange Examiners Courses as required. Any disputes or queries about the Achievement scheme shall be decided by the sub committee.

Examiners

Two recognised MACI examiners shall give examination in either level and in all disciplines. Helicopter or Aircraft examiners are required as appropriate and at least one must be from the relevant category being tested. Examiners can be from any club including the candidates own club.

Examiners shall be appointed by MACI upon the written nomination of their primary listed MACI club and only then after attending a course or seminar as prescribed by the Council. The status of an Examiner is valid for three membership years including the year of course attendance. The membership card shall show the status of examiner.

A club may only nominate a person as an Examiner if he is a MACI member in good standing and the holder of a B Certificate on the day of attendance at the Examiners course or if a holder of an A cert on the day of attendance at the Examiners course then they must pass a "B" cert exam within 90 days of attending an Examiner's course.

Site of an Examination

The A certificate examination may be taken by a candidate at his/her own MACI registered Club site. The B certificate examination may not be taken by a candidate at any club to which the candidate is affiliated or any of the sites that the club have registered.

Examination Format

The examination shall consist of 4 sections. Satisfactory completion of Section 1 is compulsory before proceeding to the remaining sections. All components of the Test must be completed in the one session.

As the tests are for pilot competency and not of a models capability it is incumbent on each pilot to present himself/herself with an appropriate model aircraft for the test being undertaken. This model must be capable of Rise off Ground on its own undercarriage or a dolly.

  1. Ground Check of Model

    By examination

    • Proof of MACI membership
    • MACI Registration number displayed on model
    • Conform with Local Frequency Control
    • Transmitter Frequency as stated
    • Radio installation (check servo directions)
    • Engine installation check
    • Tank / Fuel system check
    • Propeller /Rotors - no nicks/damage
    • Airframe - control surfaces/hinging
    • Pushrods / Linkages check
    • Range Check and Failsafe test with engine running (engine off for helicopter)

    By enquiry

    • Propeller – balanced?
    • Batteries adequately charged?
    • Centre of Gravity check?
    • Have you read the Documentation?
    • Large Model Permit if required

  2. The candidate shall be asked the appropriate number of questions from the "Code of Safe Practice". A pass rate of 8 from 10 in the A Cert. and 12 from 15 in the B Cert. to pass.
  3. Observation of candidate during pre-flight safety check, model preparation, engine start and range check with Engine on for Aircraft and off for Helicopters).
  4. Flying the A or B Certificate flight schedule.

There is no time limit on an examination or any flight. Only the Examiners may accompany the Pilot to the Flight line. Provision should be made where possible to take control of a model if unsafe conditions arise.

An Instructor may be in attendance but cannot communicate with the Pilot.

The Examiners will determine the flight line and pilot position allowing for wind direction and local conditions.

The Examiners may terminate the test any time and at their discretion.

The Examiners shall not look for exceptional quality or perfection in manoeuvres, but rather for the display of safe and adequate control of the model at all times. The Examiners shall take into consideration the entire flight including flying between manoeuvres. All manoeuvres must be carried out in front of the pilot.

At no time during the flying test should the aircraft be flown behind the pilot or examiners, this will constitute an automatic fail.

With the prior permission of the Examiners an intermediate landing may be allowed for a person flying an electric model for the purpose of refitting a fully charged flight battery.

Termination of a flight due to engine or other mechanical failure will be deemed an attempt. Because of the significance of the B test, a higher standard of control shall be looked for.

Result/Scoring

The result shall be either a pass or a fail.

A candidate must pass each item in a section to pass that section and a candidate must pass all 4 sections in order to pass the examination.

For the A test in the flying section of each category, a candidate may make two attempts at each manoeuvre, excluding landing, and two attempts at the entire flight schedule.

For the B test, in the flying section of each category, a candidate may make only one attempt at each manoeuvre and only one attempt at the entire flight.

Upon completion of the test, a candidate who has passed shall be given a Receipt giving Confirmation of a pass, completed and signed by both examiners. The Examiners will return their Checklist immediately to the Membership Secretary of MACI for processing and filing. The candidate shall keep the receipt in case of an enquiry. Upon receipt by MACI, the register of achievement tests shall be updated accordingly and the member's membership card amended to show the new achievement level when next issued. In the event of a failure, a candidate may not repeat an A or B Cert. examination for at least two weeks.
