FMS-HGS

Question 1

Can the FMS be used if the database is out of date?

Answer 1

Yes

Current charts shall be used when comparing instrument flight procedures against an out-of-date navigation database.

Enroute and Terminal Operations (SIDs, STARs, and DPs)

FOM2.3.1

Question 2

VNAV vertical path angles are limited to not more than:

Answer 2

VNAV

• VNAV vertical path angles greater than 6° in enroute and terminal mode and greater than 4° in approach mode are prohibited.

FSM 1.8.6

Question 3

FMS temperature compensation procedures must be applied to approaches at what reported airfield temperature?

Answer 3

For temperatures of 0°C or less, pilots shall apply temperature compensation to published Instrument Approach Procedures to ensure adequate obstacle clearance.

Question 4

What types of FMS approaches require two operational FMSs?

Answer 4

Two operational UNS-1Ew FMSs with functioning GPS sensors are required for any RNAV (RNP) approach or for any RNAV approach to LPV minimums.

FSM 7.6.19

Question 5

Can an FMS-based approach be continued beyond the FAF with a POS annunciation on the PF FMS?

Answer 5

No, an FMS missed approach is required.

FSM 7.6.32

Question 6

Does an FMS approach and the associated approach transition (if required) have to be retrieved from the FMS database?

Answer 6

A transition shall always be loaded with an approach. If a transition is not loaded, FMS may not fly approach properly.

FSM 7.6.9

Question 7

Can you manually build a missed approach procedure in the FMS and fly it if IMC?

Answer 7

No, all missed approaches must be loaded from the database

Question 8

Which type of FMS approach requires tuning of a ground based NAVAID?

Answer 8

Localizer Approaches
Localizer approaches may be flown using the FMS provided:
• The approach procedure is titled LOC or BC. Do not use the LOC-only minimums of an ILS.
• Both VHF nav receivers are tuned to the localizer frequency.

FSM 7.6.20

Question 9

Can the final segment of an ILS approach be flown utilizing the FMS as primary navigation?

Answer 9

• Any portion of an ILS approach may be flown via the FMS except for the final segment. The final segment of an ILS shall be flown via ground-based ILS guidance. Normally the missed approach is flown via LNAV.

FSM 7.6.20

Question 10

Is the autopilot required to be used during RNP less than .3 approaches?

Answer 10

RNAV (RNP) Approaches
• The UNS-1Ew FMS is approved for RNAV (RNP) approaches to an RNP level of:
- With flight director, 0.30 nm for approach,
- With Autopilot, 0.10 nm for approach, and
- Less than 1.0 nm for missed approach.

Bulletin 13-16FSM

Use of autopilot is required for approaches when using lines of minima less than RNP 0.30.

Bulletin 13-6 FSM

Question 11

Is manually selecting the RNP value to .1 in the FMS prohibited?

Answer 11

Yes
Manual selection of RNP value in the FMS is prohibited.

Bulletin13-08 FSM

Question 12

Under what conditions do you not have to go missed approach when the CDI
is full scale deflection on a RNP approach?

Answer 12

NOTE: Momentary full scale deflection of the CDI needle associated with a waypoint crossing that includes a course change or a reduction in RNP does not require an immediate missed approach provided the aircraft acquires the new course in an appropriate manner.

Bulletin 13-12

Question 13

What is the maximum glideslope angle when using the HGS in AIII mode?

Answer 13

Is a takeoff abort required if the HGS fails when the RVR is less than 500?

Question 14

When conducting an ILS approach in AIII mode, the gear and flaps must be in the landing configuration prior to what point?

Answer 14

HGS must be in the AIII mode, with gear and flaps in the landing configuration prior to passing the Final Approach Fix. QX FSM 1.8.2

Question 15

What is the proper response to an APCH WARN annunciation when below 500 feet?

Answer 15

APCH WARN is annunciated in the combiner or on the HAP below 500′ above DH. FSM 7.7.3

Question 16

During an AIII approach, what will the first officer verify is annunciated on the HAP prior to passing the FAF?

Answer 16

First Officer shall verify AIIIRO ARM is annunciated on the HAP prior to passing the final fix. FSM 7.7.2

Question 17

Is a takeoff abort required if the HGS fails when the RVR is less than 500?

Answer 17

HGS failure, “TO WARN,” or loss of HGS symbology during takeoff below 500 RVR when the runway centerline is not in sight. FSM 2.1.13

Question 18

What are the wind limitations for Cat III approaches?

Answer 18

• Maximum crosswind component is 15 knots. -Maximum tailwind component is ten knots. -Maximum Headwind component is 25 knots. FSM 1.8.2
