Low Visibility

Question 1

When does SMGCS plan go into effect?

Answer 1

visibility less than 1200 RVR

Question 2

What are the 2 levels of SMGCS?

Answer 2

1. RVR between 1200 and 600

2. RVR less than 600

Question 3

When MUST you use RVR for takeoff?

Answer 3

When it’s available. Usually when RVR is below 1600

Question 4

Can you apply the RVR for a specific runway to another runway at the same airfield?

Answer 4

No, RVR for a specific runway only applies to that runway

Question 5

What RVR is controlling if RVR at takeoff is at or above 1600?

Answer 5

Touchdown zone, if it’s unavailable you may substitute MID RVR. Only above 1600 RVR

Question 6

What are the requirements for takeoff RVR less than 1600?

Answer 6

1. At least 2 RVR reports
2. ALL available RVR reports are controlling.
   - RVR > 1600 TDZ may be substituted for MID

Question 7

Can you use a “far-end” RVR report for takeoff as 1 of the 2 required operative RVR reports?

Answer 7

NO, far-end RVR reports are not considered controlling and may not be substituted for 1 of the 2 required RVR reports.
TDZ , MID

Question 8

Takeoff RVR is 1600 or RVV 1/4sm. What is required?

Answer 8

• TDZ RVR (beginning of TO roll) or RVV is controlling
• 1 of the following visual aids MUST be available:
  1. HIRL
  2. CL
  3. RCLM - Rwy centerline markings
  4. Adaquate visual reference to identify rwy

Question 9

1200/1200/1000 at Takeoff

Answer 9

• TDZ RVR, Mid-RVR (if installed), roll-out RVR
• RVR + 1 of the following MUST be available:

Daylight:

1. RCLM
2. HIRL
3. CL

Night:

1. HIRL
2. CL

Question 10

1000/1000/1000 at Takeoff

Answer 10

RVR + 1 of the following MUST be available:
1. CL
or
2. HIRL and RCLM

Question 11

600/600/600 at takeoff

Answer 11

RVR + BOTH MUST be available:

1. HIRL and CL

Question 12

What is the CAT I approach minima?

Answer 12

1. 1800 RVR:
   - Operative TDZ and CL

If no TDZ and CL or INOP:

• Operative Flight Director Required
• Approach may be hand-flown, but MUST use FD

Question 13

Autopilot disconnects due to a malfunctioning FD on an approach to a runway 1800RVR, no TDZ or CL. What do you do?

Answer 13

Execute the Missed Approach

The FD MUST be functional and usable on an approach to a runway without TDZ and CL

Question 14

When do we have to go missed on an approach?

Answer 14

At or Below the DA, MDA/MAP and the following is not met:

A. Flight visibility less than IAP minimums
B. At least 1 of these references clearly identifiable:
1. Approach Lighting system, with red side row / terminating bars - 100ft above TDZ
2. Threshold, markings and lighting
3. RWY, markings and lighting
4. TDZ, markings and lighting
5. VASI / PAPI
6. REIL

Question 15

When may you continue down to, but not below, 100ft above the TDZ on an approach?

Answer 15

With the Approach lighting system visible and:

1. Red side row bars
2. Red terminating bars

Question 16

What do you do if you see the approach lights, but not the red side row / terminating bars at the DA/MAP?

Answer 16

GO MISSED

Question 17

What do you do if you see the Approach lighting system and Red side row / terminating bars? Can you land?

Answer 17

Continue to 100ft above TDZ

Yes, with additional visual references

Question 18

What do you do if you see the approach lights, REIL and Threshold, but not the red side row / terminating bars at the DA/MAP?

Answer 18

Continue to land. You have adequate visual references. That runway may not be equipped with Red bars

Question 19

What are the CAT II limitations?

Answer 19

SOPM 4-12.16

1. Use of AP below 50’ prohibited
2. At least 1 radar alt (w/test) required.
3. Non-coupled / hand flown prohibited.
4. Mandatory flaps 5
5. Below 500’: deviation 1/3 or 1 dot require missed approach
6. Missed approach mandatory when WX below mins, NAV equip becomes inop.
7. No wind limits.
8. No placards prohibiting Cat II.. Meaning Cat II certified.
9. TDZ RVR
10. HIRL, CL
