24
Q

Use of NAV Mode

  • AFTER T/O
  • IN TERMINAL AREA
A

NAV mode can be used as long as GPS PRIMARY is available

25
Q

Use of NAV Mode

- APP Based on NAVAIDS

A

A navaids app may be performed in NAV, APP NAV or FINAL APP, with AP and FD engaged, provided that:
- If GPS PRIMARY is available, the reference navaid may be unserviceable, or the airborne radio equipment may be inoperative, or not installed, provided that an operational approval is obtained
- If GPS PRIMARY is not available, the reference navaid and the corresponding airborne radio equipment must be serviceable, tuned and monitored during the approach.
Note: FLS is the recommended managed lat and vert guidance mode for radio navaids approach.

26
Q

Use of NAV Mode

- RNAV APPROACH

A

AN RNAV(RNP) app may be performed, with GPS PRIMARY not available, only if the radio navaid coverage supports the RNP value and HIGH accuracy is displayed on the MCDU with the specified RNP, and an operational approval is obtained.

An RNAV(GNSS) app may be performed provided that GPS PRIMARY is available

27
Q

Navigation Database Validation

RNAV (GNSS) Approaches and approaches based on VOR/NDB

A

To fly an app in Lat managed mode or lat and vert managed mode, the app stored in the NAv database must be either:

  • Produced by an approved supplier compliant with ED76/DO200A requirements, or
  • Validated and approved by the operator.

Note: RNAV(GNSS) approaches lat trajectories are geometrically based on wypts coords. Thus, validating wypts coordinate ensure no coding error on the app and correct lat trajectory. Observed lat track deg of difference between MCDU F-PLN pg display and charts may come from inconsistency between FMS MagVar and charted MagVar, which has no effect on lat trajectory.

Autoland is not allowed below -1000ft Pressure ht

NOTE: Auto rollout performance is approved on dry and wet runways, but not demonstrated on snow covered or icy runways.
During auto rollout one inop or one thr reverser inop, flight crew may use remaining reverser, provided that wind condition does not exceed max for auto rollout.
(VH-XUH - do not use more than idle thrust)

35
Q

Automatic Landing cont…..

A

Auto landing system perf is demoed with CAT 2 or CAT 3 ILS/MLS airport installation. However, autoland in CAT 1 or better weather conditions is possible on CAT 1 gnd installations or on CAT 2 / 3 ground installations when ILS/MLS sensitive areas are not protected, if the follow precautions are taken:

  • The airline checked that the ILS/MLS beam quality, and the effect of the terrain profile before the RWY have no adverse effect on AP/FD guidance. Particularly terrain profile 300m before the RWY threshold.
  • The flight crew is aware that the LOC or G/S beam fluctuations independent of the A/C sys ay occur. The PF is prepared to immed disconnect should unsat guidance occur.
  • At least CAT 2 capability is displayed on FMA and the flight crew uses CAT 2or 3 procs.

51
Q

GPWS / Predictive GPWS

A

All NAV must not be based on the use of the terrain display.

The terrain display is intended to serve as a SA tool only, may not provide the accuracy upon which to solely base terrain avoidance manoeuvring.

The predictive GPWS functions should be inhibited (TERR Pb off) when A/C position is less than 15 nm from the airfield:

  • For ops to or from RWYS not incorporated in the predictive GPWS database
  • For specific approaches which were previously identified as potentially causing false terrain alerts.

Only A/C with Man-made obstacle function can display obstacles on ND that trigger alerts, based on a dedicated database which includes artificial obstacles worldwide.

52
Q

FUEL - Temperature

A

JET A1/ JP8/ JP5………………-43 to +54 degs C

53
Q

FUEL Temp limits when JP4 and JET B Fuels are used

A
  • If wing fuel temp > 30 degs C at eng start, alt must be limited to 35000ft till centre tank is empty.
  • If wing fuel temp > 40 degs C at eng start, alt must be limited to 30000ft till centre tank is empty.
  • If wing fuel temp > 49 degs C at eng start, alt must be limited to 25000ft till centre tank is empty.
    Reason: At high altitude with high fuel temp, the pressure supplied by the centre tank pumps becomes lower than the pressure supplied by the wing tank pumps.
54
Q

2250 kg 2250 kg
*The variation is linear between these values, and there is no limitation below 2250 kg

OUTER TANKS
Max Asymmetry 690 kg (1)
Note (1) - The Max fuel imbalance in the outer wing fuel tanks (one full/one empty) is allowed provided that:
- The fuel quantity of the outer and inner wing fuel tanks of one side is equal to the fuel quantity of the outer and inner wing fuel tanks on the other side, or
- On the side of the lighter outer tank, the fuel quantity of the inner tank is more than the fuel quantity of the opposite inner tank. The difference between the fuel quantity in the inner tanks should not be more than 3000kg.

Note: In exceptional conditions (i.e. fuel sys failure), the above-mentioned values for max fuel imbalance may be exceeded without significant effect to the a/c handling qualities. The a/c remains fully controllable in all flight phases.
