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)
<1000’ RA หากเกิดสิ่งเหล่านี้ขึ้นให้ go around
- Eng failure
- @ floor
- Loss both AP
- Downgrade CAT
- Amber caution
- ISIS Flag
Wind limit
Maximum T/O X-wind 50% of normal (15kt)
Wind Component L/D Head / X / Tail
- 320 -> 30/20/10
- 321 -> 15/10/10
visual reference
visual reference -> combination of at least 3 consecutive light
- approach light
- touchdown zone light
- centerline light
- runway edge light
LVO T/O
- 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
LVO L/D
- 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
Light in CAT1 in night operation
- Runway edge light
- Runway end light
- Threshold light
- Approach light
Autoland limitation
- glideslope 2.5degree to 3.15(CEO) , 3.25(NEO) degree
- with airport elevation <= 2500’(CEO) , 9200’(NEO)
Autoland Light
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’
Fail Passive Fail Operational
Fail Passive
- failure no significant out of trim condition -> CAT3 SINGLE
Fail Operational
- failure landing can be complete by the remaining automatic -> CAT3 DUAL
ETC*
- 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
