| It was also unusually well equipped with the latest avionics, including TCAS II Change 7, TAWS and satcom. |
|
| There is no requirement for aircraft in Canada to be TCAS equipped, and neither of the two accident aircraft was so equipped. |
|
| The return signal is tracked by the TCAS, allowing it to predict the track of an aircraft. |
|
| All TCAS Resolution Advisories should be collected in the ECCAIRS data base. |
|
| The DLH493 pilot queried the initial turn as it would have him turn into the traffic he saw on his TCAS display. |
|
| This type of tool would provide an additional safeguard, much as TCAS does, to avoid losses of separation or midair collisions. |
|
| After following the controller's instruction, the pilot of DLH411 advised he was climbing the aircraft in response to a TCAS resolution advisory. |
|
| Ground proximity warning alerts have priority in the cockpit over TCAS alerts. |
|
| Although the TCAS systems were not needed to resolve the conflict between the two flights, they helped the crews visually acquire and monitor their aircraft traffic. |
|
| Aircraft operating in Class G airspace, without the benefit of ATC traffic advisories, are not required to be equipped with a TCAS or a transponder. |
|
| The pilots of CDN636 also received a TCAS RA and climbed their aircraft. |
|
| Neither could it be determined whether the self-test of the TCAS had been carried out before departure or on previous flights on the day of the occurrence. |
|
| It also features EFIS, Autopilot, FMS, EGPWS and TCAS resulting in a powerful and cost effective training solution. |
|
| However, it was judged by the industry to be unfeasible due to limitations in the accuracy of the TCAS directional antennas. |
|
| Hence, all work on TCAS III was suspended and there are no plans for its implementation. |
|
| The illustration below gives an example of a typical TCAS protection volume. |
|
| The safety study also shows that TCAS II will induce some critical near midair collisions. |
|
| Originally designated TCAS II Enhanced, TCAS III was envisioned as an expansion of the TCAS II concept to include horizontal resolution advisory capability. |
|
| A protected volume of airspace surrounds each TCAS equipped aircraft. |
|
| One potential problem with TCAS II is the possibility that a recommended avoidance maneuver might direct the flight crew to descend toward terrain below a safe altitude. |
|
|
|
| The new simulator will serve the academy by familiarizing its students with the commercial jet flight deck, FMS, EFIS, TCAS, EGPWS, weather radar, performance and speed. |
|
| A short time later, prototypes of TCAS II were installed on two Piedmont Airlines Boeing 727 aircraft, and were flown on regularly scheduled flights. |
|
| Drossman does not favor TCAs such as amitriptyline, which may cause side effects that limit tolerability through anticholinergic and antihistaminergic effects. |
|
| Routinely used TCAs include protriptyline, desipramine, and imipramine. |
