Compatibility with Existing Infrastructure

For UAVs operating at existing airfields, ground handling and flight line maintenance procedures should be similar to those of manned aircraft in order to comply with the principle of transparency84.

During certain activities, such as towing, additional procedures must be created to compensate for functions that were accomplished by humans, such as lookout and emergency braking.

It has already been mentioned that it will be beneficial if UAVs use similar consumables to those of manned aircraft. Operating from most military airfields will necessitate the use of kerosene rather than Avgas. The use of kerosene will also increase the safety of the platform and extend the range of operations. Although some manned aircraft still use Avgas, the requirement to use kerosene will enhance the operations of especially large long range UAVs.

SUMMARY

South Africa clearly has a requirement for UAVs to carry out tasks that classify as “dull, dirty and dangerous (D3)”. Many of these tasks are in areas that have a low population density and are not in areas that have high air traffic density. UAV development could therefore concentrate on fulfilling these mission requirements and develop the airspace regulations in parallel. Once the UAV technology has been proven in this airspace, it can be expanded and moved to more densely populated areas when the airspace regulations are in place.

Although the subject of UAV design is outside the scope of this document, it does have a direct impact on the generation of Standards and is conversely affected by the regulations in force when the UAV is designed. It is therefore vital that UAV designers familiarize themselves with current airspace regulations since it can significantly influence their design.

Further research into UAV designing must be executed in order to ensure that when standards are transferred from manned aircraft, or when new UAV design standards are proposed, that they are relevant and correct. The future design of UAVs will probably break new barriers that were not possible with manned aircraft, mainly because of the human limitations, and it is

inevitable that new designs, standards and regulations will be created in order to accommodate this.
