The TSB is now asking Transport Canada (TC) to require that approach charts used by pilots to depict the optimal path to be flown rather than the line joining the obstacle clearance altitudes which is currently shown and that the stabilised constant descent angle approach technique be used by Canadian operators that conduct non-precision instrument approach procedures.
Obstacles: Intuitively enlarges obstacle(s) as aircraft approaches; TAWS based colors are used when the required obstacle clearance is not met or in the case of potential obstacle impact -- Traffic: TCAS traffic symbology represented in 3D that changes size relative to range -- Flight Path Marker: Displays projected path of the aircraft -- Zero Pitch Line: Clearly distinguishes aircraft's altitude in relation to nearby terrain -- Gridlines: Drawn on the terrain surface and enhances distance perception -- Runways: Runway designations and thresholds are superimposed on terrain data; Unique runway highlighting and enhancements improves runway visibility from a distance -- Airport Signs: Depicts identifier of nearby airports
Although classified as a monobox minivan, in line with Mitsubishi Motors' All Wheel Control (AWC) vision of active safety Delica D:5 sports electronically-controlled 4WD, Active Stability Control (ASC) together with ample obstacle clearance angles and ride height to give it improved running performance and stability both on- and off-road.
The profile issue was important as we had to satisfy different obstacle clearance requirements to those used by military operators; this involved removing obstacles--including 16ft from a hill--and extending the runway so that the thresholds could be adjusted to give better obstacle clearance on the approaches.
