Limitation regarding Door Mounted Power Assists and Escape Slides ?
Main door emergency power assists and evacuation slide systems must be armed with the mode select handle in the ARMED position prior to taxi, takeoff and landing whenever passengers/supernumeraries are carried.
Limitation regarding Flight Deck Security Door ?
Verify that an operational check of the Flight Deck Access System has been accomplished according to approved procedures once each flight day.
Limitation regarding Lower Crew Rest Compartment ?
The lower crew rest compartment may not be occupied, and the main entry hatch must be closed during taxi, takeoff, or landing.
Limitation regarding HF ?
Do not operate HF radios during refueling operations. .
Radar Limitations on the ground ?
Avoid weather radar operation in a hangar or within 50 feet (15.25 meters) of fueling operations or a fuel spill.
Avoid weather radar operation when personnel are within the area normally enclosed by the aircraft nose radome.
Note: The hangar recommendation does not apply to the weather radar test mode.
Limitation regarding Hand Microphone ?
Remove any power cords from flight deck PC power outlets before using a hand microphone.
Severe Turbulent Air Penetration Speed ?
Below 25000 feet : 270 kts
At or above 25000 feet : 280 kts or M.82 whichever is lower.
Maintain a Minimum Speed of 15 kts above the MMS at ALL ALTITUDES when airspeed is below M.82 !
Contaminated Runway Definition ?
Runway of which more than 25% of the runway surface area within the required length and width being used is covered by the following:
- Surface water, or slush, or loose snow, or wet snow more than 3 mm (0,125 in) deep
- Compacted snow which has been compressed into a solid mass which resists further compression and will hold together or break into lumps if picked up.
- Ice, including wet ice.
Note: All contaminants, except compacted snow and ice, with depth less than 3mm (0.125in) is considered as wet.
Standing Water Definition ?
Standing water is caused by heavy rainfall and/or insufficient runway drainage with a surface water depth of more than 3 mm (0.125 in).
Slush Definition ?
Mixing more or less liquid which is formed by water and ice when melting. A recent dry snowfall on slush is equivalent to slush.
Dry Snow Definition ?
Snow that can be blown if loose, or if compacted by hand, will fall apart again upon release. It is not a melting snow.
Compacted Snow Definition ?
Snow that has been compressed into a solid mass which resists further compression and will hold together or break into lumps if picked up. It is not a melting snow.
Wet Snow Definition ?
Snow that has grains coated with liquid water, which bonds the mass together, but has no excess water in the pore space. A well-compacted, solid, snowball can be made, but water will not squeeze out.
* Wet Snow is not available in OPT. In case of Wet Snow use Slush in OPT.
Ice Definition ?
Runway is considered as icy when the runway surface is covered with no melting ice.
Taxi, Takeoff & Landing Mu (Friction Coefficient) Limitation ?
Mu 0.2 & below is prohibited
Takeoff & Landing on Wet or Contaminated Runway Depth Conditions Restrictions ?
Standing water>12.7mm (0.5inch) TO&LDG forbidden
Slush, wet snow>12.7mm (0.5inch) TO&LDG forbidden
Dry snow>101.6mm(4inch) TO&LDG forbidden
Ice Melting or Wet Ice: NO DEPTH TO&LDG forbidden
Maximum takeoff steady-state crosswind component is limited to ?
40 knots
Reduce all takeoff crosswind guidelines by 5 knots if thrust is above ??% N1 at brake release for takeoff roll.
40%
Landing Crosswind Limitations (Gust Included)
RCC 6 = 45kts RCC 5/BA GOOD =40kts RCC 4/BA GOOD to MEDUIM =35kts RCC 3/BA MEDIUM =25kts RCC 2/BA MEDIUM to POOR =17kts RCC 1/BA POOR=15kts
Reduce landing crosswind guidelines by 5 knots on wet or contaminated runways whenever ??? is used.
Asymmetric reverse thrust.
Landing on untreated ice or snow should only be attempted when ??? is present.
No melting
Sideslip only (zero crab) landings are not recommended with crosswind components in excess of ?
28 knots.
This recommendation ensures adequate ground clearance and is based on maintaining adequate control margin.
Approved tire limitation ?
Capable of a maximum of 204 kts takeoff speed must be installed.
RVSM Operations CPT or F/O altimeter limitation ?
Prior to takeoff the maximum allowable difference between Captain’s or First Officer’s altitude display and field elevation is 75 feet.
RVSM Operations Standby altimeter limitation ?
The Standby altimeter does not meet altimeter accuracy requirements of RVSM airspace.
RVSM Operations Gear limitation ?
RVSM operations are prohibited when conducting landing gear extended operations.
RVSM Operations Required Equipment ?
*2 Static Air Data Modules (for the independent altitude measurement) and the following EICAS messages are not displayed :
[AIR DATA SYS and/or SGL SOURCE AIR DATA]
*2 PFD (for altitude indications)
*1 AP (for automatic altitude-control)
*1 XPDR (with altitude reporting system)
*1 WES (for altitude alerting system)
