3. Functions

Visualization of relationshipbetween terrain and radio wave

‒ To grasp the relationship between terrain and radio wave conditions easily.

‒ With this function, it will be possible to prevent from setting a new flight procedure in poor radio wave conditions area.

4. Conclusion

FIDM effects

‒ Re-inspection due to the poor signal condition will be reduced by the result of coverage simulation.

‒ Partial of RNAV flight inspection will be omitted by the result of RNAV analysis.

4. Conclusion

Works to realize these effects

‒ To secure enough flight inspection data amount.

‒ To determine an appropriate modeling formula for coverage simulation.

‒ To Validate for the coverage simulation result.
