Icing conditions
If any form of visible moisture is present (such as clouds, fog with visibility of one mile or less, rain, snow, sleet, ice crystals) or standing water, slush, or snow is present on the ramps, taxiways or runways and the OAT or TAT is +10 degrees and below during ground and flight operation.
Cold soaked fuel frost is allowable when ?
Lower wing -
Air temp 4 degrees or greater
No visible moisture
Fuel tank temp greater than -16
On upper wing above conditions met and is in defined tank area
Cold weather ops - Run up
Run up required when engine anti ice is needed and OAT is 3 degrees or below.
Run up 70% N1 for 30 seconds if possible
What is the company minimum landing distance available for participation in LAHSO - wet or dry?
2200 meters
Volume A1 section 10
LAHSO conditions - Day & Night
Day - Simultaneous TO and Landings
Night - simultaneous landings only
OPT - If temp is expected to increase what do you apply to current temp for entry ?
Add 2 degrees to the current temp to account for any increases before departure
OPT - HW and TW entry
If HW is present then you can put wind as 0.
However with any TW this must be entered (round up)
OPT - What CG do you default to for calculations ?
700 - FWD LIMIT
800 - 19%
MAX - 19%
RVSM altitudes
FL290 - FL410
1000’ separation for RVSM ACFT (priority)
2000’ Non RVSM ACFT
Altimeter allowances for RVSM ACFT -
DIFF BETWEEN CPT & FO
DIFF BETWEEN ALTIMETER AND FIELD ELEVATION
Between CPT & FO - sea level to 5000’ is 50ft
5001’ to 10,000’ is 60ft
Between altimeter and field elevation - sea level to 5000’ is 75ft
5001’ to 10,000’ is 75’
EDTO -
After dispatch an EDTO alternate minima becomes what?
This now becomes the landing minima for the approach likely to be conducted.
before dispatch you can find summary table if minimas on Comply365
WX must be updated for alternates before the extended entry point
MISSED APPROACH REASONS ON LNAV APP - AFTER IAF IN IMC
XTE ALERT
POSITION UNCERTAINTY (FMC MESSAGES - UNABLE REQ NAV PERF, FMC DISAGREE, VERIFY POS)
UNABLE TO ENGAGE/RE-ENGAGE LNAV
MISSED APPROACH REASONS ON LNAV/VNAV APP - AFTER IAF IN IMC & AFTER FAF
After the IAF

due to aircraft configuration changes is acceptable)
MISSED APPROACH REASONS ON RNP AR - AFTER IAF IN IMC & AFTER FAF
After the IAF,
• XTK Error alert.
