TD49 Flashcards
What does the Go Around (Go ARND) Mode provide, and how is it engaged? Can the pilot change FPM ROC and airspeed reference?
The GO ARND mode provides pitch, roll, collective cues, and FPS commands to establish a wings level 750 fpm Rate of Climb (ROC) while maintaining 70 knots. The GO ARND hold mode is manually engaged by pressing the GO ARND button on the corresponding FD/DCP. The GO ARND button on the cyclic grip also provides a means to manually select the GO ARND mode for engagement. GO ARND can be engaged at any airspeed.
The pilot cannot change the 750 fpm ROC and 70 knot airspeed references however, the pilot can at any time engage IAS or VS modes and adjust the desired airspeed or rate of climb.
When is the LOC legend displayed on the FD/DCP? According to the student handout, when will BC be displayed on the FD/DCP?
Localizer - When a ILS localizer source is selected as the NAV source for the corresponding FD and when the difference between the selected course and the actual heading is less than 105°. Back Course - (BC mode will ARM when the difference between the selected course and the actual heading is greater than 105°)
What does the ILS DECL mode provide?
The ILS DECL provides a means to automatically decelerate the helicopter from its present airspeed to 70 knots prior to the 200-foot AGL point on the glide slope.
Once the DECL mode achieves 70 knots, the IAS mode will automatically engage and the DECL mode will disengage. The airspeed for engagement of the DECL mode is 70 knots or greater.
When can the VOR navigation mode be engaged?
The VOR navigation mode can only be engaged at indicated airspeeds of 50 knots and above. VOR can only be engaged when a valid VOR frequency is tuned and the FCC is receiving a VOR valid signal.
The VOR mode is manually engaged by pressing the VOR button on the corresponding FD/DCP.
When will the VOR mode switch to station passage mode? What happens during this mode?
When the FCC determines that the helicopter is over the VOR station. The CAP annunciation on the FD/DCP will change to SP to show the change in mode. The helicopter will stop attempting to track the VOR radial and willmaintain the heading
While in the SP mode, when will the FD/DCP indicate VOR CAP again?
When the FCC determines the VOR signal has stabilized enough for navigation, the FD/DCP will indicate VOR CAP again; or if the FCC calculates the helicopter position approx. 3 miles from t
What is the difference between a sign of hypoxia and a symptom of hypoxia?
Signs of hypoxia can be observed by other crewmembers and are
therefore considered objective.
However, individual crewmembers can observe or feel their own symptoms. Since symptoms can vary from person to person, they are considered subjective.
What does the T in the triangle indicate in the margin data?
A black triangle with a white T, signifies that the airport has nonstandard IFR takeoff minimums. The appropriate section in the front of the DOD FLIP (Terminal) charts is consulted in this case.
The MSA for OZ (RUCKR) is 25 NM. What does this provide?
The MSA is provided for emergency purposes only and guarantees 1,000 feet obstruction clearance in the sector indicated with reference to the bearing in the circle. For conventional navigation systems, the MSA is normally based on the primary omnidirectional facility on which the IAP is predicated.
