Below is an excerpt from our Operations Manuals which is being enforced at our airfield. This manual was authorized by the Civil Aviation Department of the Hong Kong Special Administrative Region.
1. Why we have prepared this rules & regulations?
Radio Control Model Aviation is an educational and exciting hobby but all powered models have to be operated in strict compliance with the following rules and regulations such that all members, guests, spectators, and the public at large can enjoy this sport and operators will act in responsible manner so as not to cause danger of injuries to others or damage to properties. Operators who are not abiding by these rule and regulations will be suspended from flying and disciplinary action taken against him/her.
2. Why we have prepared so many restrictions?
Safety rules and field rules are not an obstacle to the enjoyment of model flying, they help to prove that model flyers are the responsible people they proclaim to be. It is not a sign of intelligence to show one’s own skill among spectators. The flyer may know what he/she is doing but has no way of knowing what anyone else will do. So, it is to his/her personal benefit to make certain that no action on his/her part will result in an accident. It is therefore very important not to fly any model aircraft in competition or in the presence of spectators until it has been proved airworthy by having been previously flight tested and comply in all respect the safety rules and field rules.
These Safety Rules have been submitted to Civil Aviation Department. Any amendment to these Rules has to have prior agreement of Civil Aviation Department of the Hong Kong Special Administrative Region.
RULES & ENFORCEMENT
1. Field and Safety Rules
There is a set of field & safety rules for the Tai Shu Ha Flying Site (Field & Safety Rules III). It has its special requirements and restrictions, please ensure you read and understand them thoroughly, and comply with the said rules.
2. General Definition of Model Aircraft
a. A model aircraft is a heavier-than-air craft of limited dimensions, with or without a propulsion device, not able to carry a human being and to be used for recreational, sport or competition purposes rather than unmanned aeronautical vehicles (UAV) developed for commercial or governmental, scientific, research or military purposes.
b. Unless otherwise stated, model aircraft shall meet the following general specifications;
*Note: The are special rules/requirements for operation of model aircraft weighting from 7kg to 20kg to conform to exemption granted according to Air Navigation (Hong Kong) Order 1995 from DGCA.
3. Qualification / Classification of Flying Members
a. Flying members are classified into two (2) categories:
i) Fixed wing aircraft
ii) Helicopter & Rotary wing aircraft
b. And each category are divided into three (3) classes:
All flying members must possess a Qualification/Classification Certificate of the HKMEC affixed with the HKMEC chop and signed by the Qualification Sub-Committee (QC). This Qualification/Classification Certificate is issued by the QC under the conditions and requirements of the Club. *For qualification/classification test information, please refer to Section IV of this leaflet.
4. Restrictions for Novice flyers
For Novice flyers, all operations of radio equipments and model aircrafts/helicopters must be supervised by an Instructor. Novice flyers are not allowed to fly alone without the supervision and tuition of an ‘EXPERT’, and are not allowed to fly model weighing more than 7kg. It is strongly recommended that an electronic training system [trainer cable] should be used during flying. The electronic training system (trainer cable) makes it possible for the Instructor to override any improper inputs by the Novice flyer and is a great safety device for training. Two transmitters are connected by an optional Trainer/Data Transfer cord. When the Instructor activates the trainer switch, the Novice flyer has control of the model aircraft. When the Instructor releases the switch, control by the Instructor is regained. This is very useful when the Novice flyer gets the model aircraft into an undesirable situation.
5. Disciplinary Actions Against Offender
Disqualification, Flying Suspension and even Removal of Membership For any action violating the Field & Safety Rules, disciplinary actions listed in the rules and Section III shall apply. The Chief Marshal on duty shall report to the Management Committee (MC) on any offence which he/she took discipline action on suspension of flying. For more serious offences, the MC will take action on disqualification, further suspension or even removal of membership.
AIRFIELD SAFETY RULES

10. Noise Control
The Marshal may conduct noise test of any model aircraft. The maximum noise level allowed will be 96 dB measured at 3 m from the centre line of the model aircraft with the model aircraft placed on the ground over hard surface at the flying site. With the motor running at full power measurement will be taken 90 degrees to the flight path on the right hand side and downwind from the model aircraft. The microphone of the noise meter will be placed on a stand 30 cm above the ground in line with the motor. No noise reflecting objects shall be nearer than 3 m to the model aircraft or microphone. If a hard surface is not available then the measurement may be taken over bare earth or very short grass in which case the maximum noise level will be 93 dB. In the event a suspected model aircraft fails the test, that model aircraft must be grounded.
