Answer 2

.25* per dot

Question 3

Altitude Hold Mode (Explain)

Answer 3

-Maintains Alt. +-50’ -Must be selected within with less than 200fpm rate ascent/descent -Operates between -1000’ to 10,000’ -Operates between 70-150KIAS

Question 4

VOR Nav Mode within 10-

Answer 4

10-20* of course, HDG drops off, then provides 45* int.

Question 5

What is CIS and what does it do?

Answer 5

processes navigational data, attitude, airspeed and altitude information to provide VISUAL COMMAND INDICATIONS for cyclic and collective control, as needed, to maintain heading, altitude, and TO NAVIGATE DURING EN-ROUTE AND APPROACH OPERATIONS.

Question 6

RULE of 5 HSI/VSI 1- 2- 3- 4- 5-

Answer 6

1- #1 bearing pointer is slaved to the Doppler/GPS 2- #2 can have VOR or ADF inputs 3- Course Deviation Bar: Dop/GPS, VOR, LOC. 4- Course Dev. pointer: Dop/GPS, VOR, LOC, FM Home 5- Roll Command Bar: Dop/GPS, VOR, LOC, FM Home, Heading

Question 7

-Heading mode Provides _ of roll command for each degree of error up to _. -Results in not more than _overshoot in acquiring the selected heading with tracking error of _? -Engaged by pressing the HDG sw. on the CIS mode selector, or VOR NAV is engaged when helicopter is in excess of _ from the selected radial.

Answer 7

-Heading mode Provides 1 degree of roll command for each degree of error up to 20 deg.. -Results in not more than _overshoot in acquiring the selected heading with tracking error of 2 deg? -Engaged by pressing the HDG sw. on the CIS mode selector, or VOR NAV is engaged when helicopter is in excess of 10 Deg from the selected radial.

Question 8

ALT Hold Mode

• maintain alt w/in _?
• Vertical rates up to _, and provides altitude inputs between __ and __ at airspeeds from _ to _.

Answer 8

• maintain alt w/in +-50’?
• Vertical rates up to 200FPM, and provides altitude inputs between -1000’** and **+1000** at airspeeds **70** to **150KIAS.

Question 9

VOR NAV MODE

When selected outside _ from the selected radial, the inistial course intersection will be made in the heading mode. When the helicopter is within __ to __, the CISP beam processor will capture the VOR beam. THe CISP logic disengages __ and a __ course intercept begins.

-The intercept course will result in no more than _ oversheet at _nm at __ kias and no more than _ overshoots at ___NM at speeds of ___.When passing over the VOR, the station passage sub mode is engaged for __, when outbound course changes to a new radial ma be made.

Answer 9

VOR NAV MODE

• When selected outside `0deg from the selected radial, the inistial course intersection will be made in the heading mode. When the helicopter is within 10 to 20deg**, the CISP beam processor will capture the VOR beam. THe CISP logic disengages **HDG** and a **45deg course intercept begins.
• The intercept course will result in no more than 1 oversheet at 10nm nm at 100+-10kias and no more than 2** overshoots at _5-40_NM at speeds of **70-140kias. When passing over the VOR, the station passage sub mode is engaged for 30sec, when outbound course changes to a new radial can be made.

Question 10

ILS NAV Mode

• Cyclic pitch command to maintain an airspeed tha should not deviate more the _knots from the IAS when the ILS NAV mode is engaged.
• Collective stick position signals to maintain the altitude existing when the ILS NAV mode is engaged.
• A _degree intercept will be made as in the VOR NAV mode, except that not mor than _ oveshoots at ranges of __ should occur for airspeeds _to_KIAS.

Answer 10

• Cyclic pitch command to maintain an airspeed tha should not deviate more the 5 knots from the IAS when the ILS NAV mode is engaged.
• Collective stick position signals to maintain the altitude existing when the ILS NAV mode is engaged.
• A 45** degree intercept will be made as in the VOR NAV mode, except that not more than **2** oveshoots at ranges of **5-20NM** should occur for airspeeds **70** to **130 KIAS.
