OM-B 2.3 Standard Operating Procedures (SOPs) Flashcards
What items should be discussed between crews during a verbal handover?
- any defects
- any anomalies
- relevant OEBs which may affect the subsequent operation.
On arriving at the aircraft what items does OM-B state you should check?
What other items might you include with an eye to the operation?
- Wheel Chocks - Check in Place
- L/G Doors - Check Position
- APU Area - Check Clear
Other items you may check;
- GPU - Present?
- Steps - Front & rear/ or airbridge?
- Fueller - Present?
What 2 main items are you looking for during the Exterior Inspection (Walk Around)?
- Check structure for impact damage
- Check that there is no evident fuel, oil or hydraulic leaks.
What items must be on during the exterior inspection?
- NAV lights
- Parking Brake, to allow the brake wear indicators to be checked.
ADIRS - When would you perform a ‘Complete Alignment’ & when would you perform a ‘fast alignment.’
Complete Alignment if;
- First Flight of the day
- GPS not available & long segments in poor navaid coverage.
Fast Alignment if;
- Residual groundspeed is > 5 knots
Pre-Selected Speeds.
What speed constraint should you use for a wraparound SID?
The greater of:
- 220 knots, or
- Green Dot + 5 knots.
Altimeters Check (Initial RVSM check) What are the tolerances?
- PFD Altitude - within 25 feet of elevation
- Difference between PFDs - Maximum 20 feet
- Difference between PFD & ISIS - Maximum 100 feet
ALT Window - what do you set prior to departure (Cockpit Prep.)?
ALT Window
For ‘all’ SID types,
the FIRST stop ALT should be set.
i.e. Don’t use ALT CST to level off for you even if PRNAV Departure.
Last Minute Changes: When would a new load sheet be required?
If the LMC exceeds the following values: +10/-20 Passengers
OMB 7.4
Rules regarding LMCs & recalculating performance, what are they?
OMB 7.4
- New Loading form if +10/-20 Pax
If new loading form not required, then following criteria apply:
- If LMC is negative, no action to be taken as long as MACTOW is within 2% of the original value.
- If LMC +ve but <250 kg & MACTOW within 2%, speeds OK, reduce flex by 1º
- If LMC +ve, TOGA planned, or >250 kg, or MACTOW >2% of original, Takeoff Perf recalc using revised TOW.
Only revise ZFW/CG in FMGS if Takeoff perf is to be recalculated, otherwise revise in the cruise.
Engine Start Sequence, what should you observe?
- N2 increases
- Start valve in-line
- Bleed pressure GREEN
- Oil Pressure Increases
- 16% N2 - IGNITION
- 22% N2 - FUEL FLOW
- 15 SECS MAX after ENG Master ON - EGT Increases & N1 Increases
- 50% N2 - Start Valve Cross-Line, Igniter OFF.
After the Flight Control Check - how long does the F/CTL page remain displayed for?
20 seconds.
What conditions must be met for the autobrakes to engage during an Aborted Take-Off?
DSC 27.10.20
- Auto Brake p/b - MAX
- Ground Speed >72 knots
- Thrust Levers - Both IDLE or One Reverse
Flex Temperature Corrections, what can be used?
- Engine A/ICE ON - subtract 5 deg
- QNH Reduction - subtract 1 deg / 2 hPa
The corrections can also be added.
e.g. If A/ICE req’d & the QNH reduces, the flex can be reduced by 6 degrees.
Tailwind or Crosswind >20 knots Take-Off technique is…?
- Full Forward Stick
- 50% N1 set on both engines until stablised
- Rapidly increase thrust to 70% N1
- -Then progressively increase thrust to reach T/O thrust at 40 knot ground speed
- maintain full forward stick to 80 knots,
- then release gradually to be neutral by 100 knots
At what speed during the take-off roll is connection between NWS & rudder pedals removed?
- 130 knots (wheel speed)
- In strong cross winds, more rudder input required at this point to prevent a/c turning into wind.
What is OPT FL a function of?
Cost Index
Can you enter a cruise flight level above MAX REC FL?
- Yes.
- MAX REC FL gives the a/c at least a 0.3g buffet margin.
- You may enter a higher flight level & FMGC will accept it,
- provided it does not exceed a level at which the buffet margin is reduced to 0.2g.
How often do we need to perform a fuel check?
- as soon as practical after TOC
- thereafter a written check made at intervals not exceeding 1 hour
- verbal check made at 30 minute intervals
- Shorter flights one fuel check should be recorded unless flight time <20 minutes.
Where will you find the instrument tolerances for the hourly RVSM check in the cruise?
FCOM PRO-SUP-34
When must a navigation accuracy check be performed?
- if GPS PRIMARY is lost (as displayed on the PROG Page)
and especially if any of the following occur:
- IRS only naviagtion
- The PROG page displays LOW accuracy
- “NAV ACCUR DOWNGRAD” appears on the MCDU
Descent Gates:
- 20,000 feet - 70 nm adjusted for wind
- 10,000 feet - 35 nm adjusted for wind
- 20 nm - Reduce from 250 knots (if maintained high speed.)
- 10 nm long final or on intercept to LOC - Flap 1, 180 Knots
- > 2000 feet above TDZE - Flap 2
- Maximum; 180 knots to 6nm, 170 knots to 5nm, or 160 knots to 4nm (wind permitting)
- ~ 5nm - Managed Speed / Gear Down
Stable Approach Criteria?
OMB 2.3.16.2
- Aircraft in Landing Config.
- Target final approach speed +10 / -5 knots
- ROD < 1000 fpm (may be increased by 150 fpm per 0.5 deg that published g/s exceeds 3 deg.)
- Aircraft within +/- 1 dot of Glideslope / LOC
- Bank angle <15 deg
Transient deviations due to atmospheric conditions are acceptable
if corrected in a timely manner.
What are the maximum final approach speeds that we can accept from ATC?
- 160 knots to 4 dme
- 170 knots to 5 dme
- 180 knots to 6 dme
