THE PROCESS

1. RECONAISSANCE AND CHECKLIST

After HELIMATIC GmbH has been contacted, the HELIMATIC coordinator arranges with the customer’s local staff in charge a preliminary meeting at the assignment location in order to clear all relevant data for optimum and secure processing of the assignment. The marked-out routes are then inspected together and, with the help of a GPS system, their start and end coordinates are established exactly.

Possible danger zones along the entire length of the marked-out routes and in their direct vicinity, such as crossing power lines, roads, paths, train tracks, transmission poles, hunting hides, buildings, fences, game preserves, military safety zones, airports and their air corridors, etc., will be entered in the appropriate maps. This provides a complete assignment plan for all marked-out routes.

As a next step, all necessary information and the permits required for the operation must be applied for and obtained. For this task, the HELIMATIC coordinator gives support and advice. (The customer is responsible for ensuring security of the danger zones, while the HELIMATIC coordinator/head of operations is responsible for the helicopter flight corridor and safety clearance to the helicopter saw.)

After having analyzed all data that has been gathered, a processing plan is defined. This plan already includes the assigned locations for take-off and landing as well as for team accommodation. On the basis of all this information, the duration of the assignment and a preliminary cost assessment are calculated.

2. BRIEFING

Before any assignment begins, a briefing takes place with all participants in the projected work. The project time schedule is then defined. Here, possible timing delays due to topographical issues, such as early morning fog or low stratus, may lead to short-term modification of the original time schedule.

Under consideration of the current weather conditions and the forecast of the local weather station, the power cuts are prepared and carried out.

In most cases it becomes necessary for the customer to provide personnel for securing road crossings or removing any cut off branches from roads and paths. After all points have been cleared, all participants in the assignments take the work positions assigned to them.

3. USING THE SAW-SYSTEM

During the entire flying time, the coordinator is in radio contact with the pilot and walks below the helicopter within an appropriate safety distance, provided the marked-out route allows walking in it.

He informs the pilot of any possible dangers and provides information about the distance between the saw and the ground. In parallel, the coordinator pays attention that no unauthorized persons are within the safety distance of the saw. The customer’s representative accompanies this activity in direct contact with the coordinator.

The traffic safety obligations are defined jointly. Any specific orders of the customer or modifications of the planned schedule can be carried out on the spot.

4. END OF AN ASSIGNMENT DAY

At the end of each assignment day a final discussion takes place with the representative of the customer, and the day's journal with the corresponding performance confirmation is being generated. In addition, the preparatory measures for the following assignment day are carried out.

The HELIMATIC saw technician carries out a complete maintenance check of the helicopter saw at the end of each assignment day.
