Jcab Oral Questions T Flashcards
Describe the B787 to a layman
- the 787 is a modern twin engine aircraft.
- increased safety measures by using latest technology in avionics and flight controls
- more comfortable pax cabin through the use of outside air for air conditioning, instead of bleed air.
also lower cabin altitude.
-it relies on the electrical system and a blend of composite materials with latest aircraft designs to be efficient in operation.
What are you first impressions of the B787 and how does it compare to the B767
.
What are the fly by wire advantages and disadvantages
?????****
.Advantages
- Reduced weight and volumn
-Fewer moving parts requires less maintenance
-Precision in control
-Better interface with other systems
Disadvantages
-No direct control so all feedback is artificial
- electrical so failure or short in system could cause it to shutdown
What are your impressions of the HUD including advantages and disadvantages
.The HUD helps enhance safety by keeping important information within the outside watch part of the pilots scan.
The HUD needs to be used with other instruments so the pilot doesn’t fixate on just the HUD.
Disadvantages - Pilot fixating on the HUD and not seeing through the information and losing scan of other instruments, as it is expanded scale not great for large maneuvers.
Advantages, brings information to the pilots eyes while looking outside, as it is an expanded scale can fly very accurately.
What are the dimensions of the B787
Length = 56.7m Wingspan = 60.1m Height = 16.9m
What is the turning circle of the B787-8
Normal turn - 45.9m (8)
Minimum turn - 42.2 (8)
Pivoting turn - 34.6 (8)
Are there any differences on how you would land the B787 compared to the B767
787 - Capable of auto landing with 2 or 1 engine
- Auto-throttle can be left on without autopilot for
landing
- Touch down pitch angle 4-5 deg
- Can use flap 30 for 1 engine (performance
permitting)
- HUD to aid in the flying of approach
767 - Touch down pitch angle required appox. 5-6 deg
- single engine less drag with flaps 20 landing less
back pressure was required than 2 engine
landing
What is the preliminary pre-flight procedure
- log and documents… check on board
- Flight deck access system
Operational check… perform - Emergency equipment
smoke hood, signal kit, fire extinguisher, crash axe, fire resistant gloves, flash light, life vests, megaphone*
…check and stowed - Flight deck overhead door… closed and latched
- Emergency descent devices… Stowed
- Headsets… minimum of 4 sets stowed
- Gear pins… 5 pins stowed
- Emergency evacuation signal and cabin inter phone… check
- IRS selectors… off for 30s then back on. verify the ON BAT light extinguished
- Status display… Verify that only expected messages are shown. Oxygen pressure 860psi Dom 1250psi Int,
Hydraulic quantity no rf
Engine Oil quantity min 16qtz
Does the B767 have an EFB
Yes, class 1 (APID)
-is a portable off the shelf (COTS) - based computer, considered to be a portable electronics device (PED)
-Not mounted to the aircraft
-not connected to aircraft system for data
-not connected to a dedicated aircraft power supply
OM 4-18
What is the B787 EFB used for, and how do you use it
.Class 3 - Considered as part of an aircraft installed equipment and is installed in accordance with airworthiness regulations OM 4-18 The class 3 EFB can be used for; - Performance Calculations (OPT) -Terminal Charts -Electronic Documents -Video surveillance.
The class 1 EFB can be used for;
- Performance Calculations (OPT)
- Terminal Charts (any discrepancy class 1 is used)
- Electronic Documents
OM 2-s-3
AOR 10.2
How do you check the EFB is up to date
During Pre-Flight checking log and documents
-No memo message for Data Load
-Check no fault message
For both right and left EFB check;
Documents loaded on EFB are “Documents to be carried in an Airplane” from OM and Wireless Certificate are shown on IDENT Page, and that the current effective data are shown in WHITE (not amber). In addition check the DATA part Number for PERF_AIRPORT (against company notam) and the effective Date for the
TERM Charts Database.
What are the differences between the 787 and the 767
Many
A few examples:
1.Electrical (number of generators, distribution, cooling)
2. Hydraulics (high pressure,fewer items)
3. Air System (A/C using CAC, electrically driven, not using bleed air)
4. Flight Controls (Fly by wire),
5. HUD
6. Number of doors
7. Synoptic pages
Presence of wind shear may be indicated by what ?
In flight below 1000’, deviations from steady flight;
-15kt IAS
-500fpm vertical speed
-5deg pitch attitude, or 1 dot displacement from glide slope
At other times;
-Strong Thunderstorm radar echo, especially accompanied by heavy rain, down drafts etc. gust fronts approx 5-6nm in mainly ahead of a thunder storm
-ground temp difference is over 5 degC before and after front passes or when speed of the movement of the front is over 30kt
-In case when the change of wind direction and wind speed is great within a short time
-Virga or blowing dust is visable
-by comparing spot winds and tower reported winds.
- Terminal Doppler Weather Radar (NRT, HND, KIX, HKG)
LIDAR (NRT,HND)
- PWS caution and warning
- GPWS Windshear caution and warning
What are the wind shear precautions
-Delay the take-off
-If windshear suspected, pilots should use caution against inadvertent encounter.
Takeoff
Less than max thrust not recommended (unless dispatch performance req.)
Use most extended flaps which complies with performance
Use Longest Runway
Use F/D after takeoff
Consider increasing VR
Be alert for airspeed fluctuations during takeoff and initial climb
Know all engine initial climb attitude
Avoid using stab trim until airplane is stabilized
Crew coordination and awareness very important
If airspeed below trim airspeed, unusual C/C forces to maintain pitch
If stick shaker encountered, reduce pitch. Do not exceed PLI
Landing
Use most suitable runway to avoid areas of suspected windshear
Land with shallow Flaps
Establish stabilized approach ASAP
Use G/S, VNAV Path or VASI/PAPI to help detect flight path deviations
If A/T not connected for landing set target approach speed accordingly
Cross check F/D commands with VSI/Altimeter/G/S deviation
Crew coordination and awareness very important
Avoid large thrust reductions/trim changes in response to sudden airspeed
loss If encountered, immediately perform windshear escape manoeuvre.
How many wind shear devices are onboard the 787
2
PWS,
GPWS mode 7 - Windshear
