LVO

Question 1

RVR required

Answer 1

RVR <400m normally LVO in force
RVR Taxi -> 100m
RVR T/O -> 175m
DH/RVR CAT1 -> 200’/550m
DH/RVR LTS CAT1 -> 150’/400m
DH/RVR CAT2 -> 100’/300m
DH/RVR CAT3A -> 50’/200m
DH/RVR CAT3B -> 20’/100m
DH/RVR CAT3C -> 0’/50m
CAT 2 required TDZ
CAT 3 required TDZ & MID or RO (75m)

Question 2

<1000’ RA หากเกิดสิ่งเหล่านี้ขึ้นให้ go around

Answer 2

• Eng failure
• @ floor
• Loss both AP
• Downgrade CAT
• Amber caution
• ISIS Flag

Question 3

Wind limit

Answer 3

Maximum T/O X-wind 50% of normal (15kt)
Wind Component L/D Head / X / Tail
- 320 -> 30/20/10
- 321 -> 15/10/10

Question 4

visual reference

Answer 4

visual reference -> combination of at least 3 consecutive light
- approach light
- touchdown zone light
- centerline light
- runway edge light

Question 5

LVO T/O

Answer 5

• RVR < 400 m
• Fuel Taxi + 600 kg
• Minimum RVR takeoff 175 m
• Minimum RVR taxi 100 m
• TOGA
• T/O Alternate required
• Runway not Contaminated
• LVP in force
• if Visual reference is lost during T/O run <100kt abort T/O
• LS on

Question 6

LVO L/D

Answer 6

• 30 min extra holding fuel if weather < CAT1
• Use flap full for L/D (ปิด landing light ได้) for better vision angle
• Stabilized ที่ 1500’
• Pilot Incapacitation ระหว่าง 500’ - 100’ ต้อง go around
• > 500’ RA CP Head Down / < 200’ RA CP Head Up

Question 7

Light in CAT1 in night operation

Answer 7

• Runway edge light
• Runway end light
• Threshold light
• Approach light

Question 8

Autoland limitation

Answer 8

• glideslope 2.5degree to 3.15(CEO) , 3.25(NEO) degree
• with airport elevation <= 2500’(CEO) , 9200’(NEO)

Question 9

Autoland Light

Answer 9

LOC / GLIDE flash when lost of LOC above 15’ RA , GS above 100’ RA
AUTOLAND RED in LAND mode
- Both AP off < 200’ RA
- LOC > 1/4 dot above 15’ RA , GS > 1 dot above 100’ RA
- RA discrepancy 15’
Alert height for TAA 100’

Question 10

Fail Passive Fail Operational

Answer 10

Fail Passive
- failure no significant out of trim condition -> CAT3 SINGLE
Fail Operational
- failure landing can be complete by the remaining automatic -> CAT3 DUAL

Question 11

ETC*

Answer 11

• MABH = Minimum Approach Break-off Height -> ความสูงต่ำสุดที่เครื่องเริ่ม Miss Approach วัดโดย RA
  go around below MABH may result in ground contact
• If ILS course pointer & runway track differ > 5degree go around , manual landing if visual reference are sufficient
• AP/FD guides the aircraft along the ILS beam down to 30’
• Runway Edge light ห่างกันดวงละ 60m
• Centerline light แดงสลับขาว 900m แดงล้วน 300m
• “THAI ASIA 123 minimum 300 meter” ตอบหอเพื่อบอก minimum RVR for CAT 2/3 app เวลาโดนถาม
• Taxi Speed 10kt if uncertain position RVR less than Taxi RVR stop Aircraft & call for Tow Truck
• RA Signal not valid >8200’ APPR mode not be armed >8000’ AGL
• Minimum Runway with 45m / Maximum Slope 2%
• RVR report 800 750 700 , 250 225 200 any change report in 15sec
• not necessary to give (MID ,stop-end RVR) unless these values are lower than TDZ RVR
• บินเหนือไฟ Approach light ดวงแรก 200’ / แถบแดง 100’(300m) / Threshold 50’ (Cat 1 2 3)
• CAT2 approach followed by manual landing is not permit
