21. The tower was equipped with radio navigation and landing aids including precision approach radar, non-directional beacon and omni-directional range. 22. Precision approach runway ( SCAT-I ) with non-precision approaches RNAV and VOR / DME, but lacks instrument landing system.23. The Clinton administration gave a big boost to the precision approach when it stopped GPS scrambling in May 2000. 24. Navigational aids Precision Approach Path Indicators and Doppler Very High Frequency Omnidirectional Range ( DVOR ) were installed in 1984. 25. However, it was impossible for the autopilot installed in the aircraft to conduct an automatic go-around from a non-precision approach . 26. Additionally, the airfield is equipped with a precision approach radar ( PAR-80 ) and airport surveillance radar ( ASR-910 ). 27. Without the landing systems, pilots used non-precision approaches which resulted in delays because planes were spaced further apart, she said. 28. Developmental tests using this aircraft have demonstrated the capability to fly precision approaches using a local area differential GPS system. 29. Kjevik has a category I instrument landing system in both directions, both which are equipped with precision approach path indicator. 30. The ground-controlled approach was normal until the aircraft was seen on the precision approach radar suddenly descending below the glide slope.
