1) RTS LOW VISIBILITY PROCEDURES

Question 1

1-Are you legal for takeoff on KSEA runway 16L?

Wind: 250/10
RVR: 500/inop/500
Alt: 30.00
RWY: 16L

Answer 1

Yes.

Two RVR are required one could be inop.

Question 2

2- Do you need a takeoff alternate and why?

Answer 2

Yes. A takeoff alternate is required, and must be shown in the dispatch release because:

— the weather conditions at the departure airport are below the lowest active
approach minimums that can be flown to an engine out landing

Also you need a takeoff alternate if: (Not the case in this KSEA example)

— runway lights are inoperative and approved temporary electric lights are used

Question 3

3-How far away the takeoff alternate can it be?

Answer 3

330 nautical miles.

Question 4

4- Do you have to use the Takeoff HUD Low Visibility Procedures?

Answer 4

Yes.

Refer to OM vol 1
43.1.1 Minimum Visibility
Use of these procedures is required with less than 500 RVR (150m) on runways
supported by 300 RVR (75m) takeoff (see Jepp 10-9A page).
Requires any two of following three transmissometers. All of the following operating
transmissometers are controlling.
• Touchdown: 300 RVR (75m)
• Mid-field: 300 RVR (75m)
• Roll-out: 300 RVR (75m)
43.1.2 Maximum Wind
• Tailwind: 10 kts
• Crosswind: 10 kts
43.1.3 Minimum Aircraft Equipment to Begin Takeoff

Question 5

5-How do you set up there HUD?

Answer 5

1- CDU HUD menu- set
2- Mode - NP
3- RWY LENGTH - verified
4- VHF NAV RADIOS- Set to ILS frequency
5- LOC ident/Course- Check

Question 6

6- If the Hud/HGS is inop, are you still legal for takeoff (CA)?

Answer 6

No.

It is require by the Minimum Aircraft Equipment to Begin Takeoff.

Question 7

7- What are the FO HUD LOW VISIBILITY PROCEDURES?

Answer 7

• Remain on instruments throughout takeoff roll or until
  stopped if takeoff is rejected.
• Call out “Centerline” if ground path diverges from the localizer

Question 8

8-What are the FO takeoff mínimums?

Answer 8

• 1600 feet RVR for any RVR on that runway
• 1/4 statue mile (if no RVR is reported for that runway)

less than this values is a CA takeoff.

Question 9

9-What are the Standard US Takeoff Minimums

Source for Two Engine Aircraft ?

Answer 9

RVR 5000 or 1 mile.

Question 10

8- ILS RWY 16L SA CAT I. The visibility for the runway is RVR 1400 /inop/inop. Are you legal to shoot the approach?

Answer 10

Yes. (Only TDZ required)

Question 11

9-The HUD/HGS is INOP, are you legal to fly the approach?

Answer 11

NO

Question 12

10- What HUD/HGS mode is required?

Answer 12

• If available, the flightcrew must use the HUD in the AIII mode.

If AIII is not available,

• AII/IMC may be used. (The Captain must fly the approach.)

Question 13

11- What approach mínimums are set for ( Radio or Baro)?

Answer 13

RADIO – DH (RA) 150 feet.

If minimums are RA NA, then the approach is not authorized

Question 14

12- When does the autopilot have to be disconnected?

Answer 14

• Autopilot is authorized for use down to 50 feet AGL.

Question 15

13-Bonus Question: With the same weather for the SA CAT I ILS RWY 16L, Can you fly a CAT II APPROACH to the same runway?

Answer 15

NO
