What are the limitations for LAHSO

Answer 2

1. Prohibited on Wet Runways
2. Must have visual or electronic vertical guidance.
3. Prohibited if windshear has been reported within last 30 minutes.
4. Tail wind shall be calm (less than 3 kts)
5. If at night, LAHSO lighting must be installed.

Question 3

What is the weather minima for LAHSO

Answer 3

Ceiling no less than 1500 ft AGL.
Visibility no less than 5 statute miles.

If a VASI or PAPI installed
Ceiling may be lowered to 1000 ft AGL
Visibility no less than 3 Statute Miles.

Question 4

For Straight in Non Precision or CAT I Precision Approach what RVR is controlling?
And what may be substituted

Answer 4

Minimum Visibilitiy 1/2 mile
The TDZ RVR is controlling with the Mid and Rollout RVR being advisory only.
The Mid RVR may be substituted for the TDZ RVR.

Question 5

CAT I Precision Approach Minimum Criteria

Answer 5

Visibility down to 1800 RVR without TDZ Lights or Center LIne Lights RCL including installed but inoperative lighting if:
Must be equipped and use an approved FD, AP or HUD.

Question 6

What is the RVR Minimum for a High Mins Captain

Answer 6

4000 RVR

Question 7

If the visibility is “LOW” less than 3/4 mile or 4000 RVR what restrictions must be met

Answer 7

Runway length shall be at least 115% of landing performance required.
Precision Instrument Runway Markings or Runway Center Line Lights must be operational

Question 8

What is the derived alternate airport minimums criteria?

Answer 8

If there is only one “operational” navigational facility providing a straight in approach:
Add 400 ft to MDA and 1 SM or 1600 RVR to landing minums
If at least 2 nav facilities providing straight in approaches to 2 different runways:
Add 200 ft to MDA and 1/2 mile or 800 RVR to landing minimums.

Question 9

What are the CAT II landing mimums

Answer 9

TDZ RVR 1200
Mid RVR 600
Roll Out RVR 300

Question 10

If the TDZ RVR is OTS, can you conduct a CAT II approach?

Answer 10

NO… the TDZ RVR is required and controlling.

Question 11

Is the Roll Out RVR required for CAT II operations?

Answer 11

Yes… it is required and controlling for operations below 1600 RVR.

Question 12

May the Mid RVR report be substituted for a Roll Out RVR?

Answer 12

Yes… if it is unavailable.

And it must be 600 RVR or greater.

Question 13

May the Far End RVR be substituted for a Roll Out RVR

Answer 13

Yes… if it is unavailable.
And must be 300 RVR or greater.
They are advisory only, unless used as a substitute for the Roll Out RVR.

Question 14

What lighting is required for CAT II Operations

Answer 14

HIRL
TDZ Lighting
CL Lighting
ALSF 1 or 2 (sequenced flashing lights may be inop)

Question 15

If the sequenced flashing lights on an ALSF 1 or 2 lighting system are inop, may you continue a CAT II approach to CAT II minimums?

Answer 15

Yes

Question 16

What are the CAT II minimums if only TDZ RVR is available

Answer 16

1600 RVR

Question 17

What are the CAT II minimums if TDZ RVR and Roll Out RVR are available?

Answer 17

TDZ 1200 RVR Minimum

Question 18

Max Crosswind component for CAT II Ops

Answer 18

15 KTS

Question 19

What is required to fly an approach to 1800 RVR

Answer 19

Engage and use the FD in approach mode down to the MDA or initiation of the missed approach procedure.

Question 20

For a CAT I Straight in Precision Approach, may the mid RVR be substituted for the TDZ RVR?

Answer 20

Yes… if the TDZ RVR is unavailable

Question 21

Lower than Standard Takeoff Minima

What is required for TDZ at or above 1600 RVR

Answer 21

TDZ RVR is controlling

The Mid may be substituted if the TDZ RVR is unavailable.

Question 22

Lower than Standard Takeoff Minima

What is required for operations below 1600 RVR

Answer 22

A minimum of 2 RVR’s required
All available RVR’s are controlling.
A far end RVR is advisory and not controlling and not to be used as one of the required 2 RVR’s
