Question

In FIXED thrust modes, the autothrust sets and maintains a constant ______ setting. The fixed thrust settings include: _______, _______, or ______. When a FIXED thrust mode is in use, the FMS uses ________ to control speed. FIXED THRUST: _______ controls SPEED. A330 V2 22.2.7.4 V2 22.2.8.2 FIXED THRUST MODES

Answer 1

In fixed thrust modes, the autothrust sets and maintains a constant **_THRUST_** setting. The FIXED thrust settings include: **_MCT_** **_CL_** or **_IDLE_** When a FIXED thrust mode is in use, the FMS uses : **_PITCH_** to control speed. FIXED THRUST: **_PITCH_** controls SPEED. V2 22.2.7.4 Active Autothrust Modes In fixed thrust modes, the autothrust sets and maintains a constant thrust setting. The fixed thrust settings include: (MCI) MCT CL (climb), or Idle, . When a fixed thrust mode is in use, the FMS uses pitch to control speed. V2 22.2.8.2 Fixed Thrust Modes When the autothrust is operating in a fixed thrust mode, FMA column 1 displays THR combined with the appropriate commanded thrust setting in green: FMA Indication Meaning THR MCT The most forward thrust lever is in the MCT detent (engine-out). THR CLB The most forward thrust lever is in the CL detent. THR LVR Both thrust levers are below the CL (or MCT detent with one engine) or, one thrust lever is in CL and the other is above the CL detent. THR IDLE Both engines are at idle thrust. THR DCLB 1(2) The most forward thrust lever is in the CL detent, and a derated climb has been selected in the MCDU. THR DES Minimum thrust in a managed descent Note: During takeoff or go around, when autothrust is armed, the FMA will display MAN TOGA, MAN FLX, or MAN DTO to indicate that the thrust levers are positioned properly. However, since these thrust settings are not commanded by the autothrust system, they are not considered autothrust modes.

Answer 2

In VARIABLE thrust modes, the autothrust varies the thrust within its authority range to maintain the selected or managed **_target speed._** When VARIABLE thrust is in use, the FMS uses: **_THRUST_** to control speed and **_PITCH_** to control vertical flight path. VARIABLE THRUST: **_THRUST_** controls SPEED 22.2.8.3 Variable Thrust Modes When the autothrust is operating in a variable thrust mode, FMA column 1 displays SPEED or MACH in green. FMA Indication Meaning Speed Autothrust is maintaining the target speed Mach Autothrust is maintaining the target mach The target speed may be either selected on the FCU or managed by the FMS. When in SPEED or MACH, the autothrust will not command thrust that causes the speed to exceed the following limits, regardless of the speed selected: Selected speed Lowest: VLS Highest: VMAX (VMO/MMO, VFE, or VLE as appropriate) Managed speed Lowest: Maneuvering speed (Green Dot, S, F as appropriate for flap configuration) Highest: 320 Knots/.84 Mach, VFE, or VLE (whichever is lowest) In descent phase: 315 Knots/.83 Mach, VFE, or VLE (whichever is lowest)

What is the Engine Run Up during Icing Conditions? 200: PW 15 MIN: 50% N1 for 01 SEC 323: PW 15 MIN: 50% N1 for 01 SEC 302: GE 30 MIN: 60% N1 for 30 SEC 900: TRNT Standing TO: HOLD BRAKES 50% N1 for 02 SECs RELEASE BRAKES 5.16.2 Cold Weather Operation Considerations associated with cold weather operation are primarily concerned with low temperatures and with ice, snow, slush, and standing water on the airplane, ramps, taxiways, and runways. Icing conditions exist when **OAT** (on the ground) or **TAT** (in flight) is **10°C** or below and any of the following exist: visible moisture (clouds, fog with visibility of **one** statute mile (**1600m**) or less, rain, snow, sleet, ice crystals, etc.) is present; or ice, snow, slush or standing water is present on the ramps, taxiways, or runways.

WHAT IS VMAX? V2 23.22.2.10.1 VMAX VMAX is a common term used to describe the lowest of: * V**MO**/M**MO** (maximum **operating** speed, or maximum **operating** **mach**) * **VLE** (maximum **landing gear** extended speed) * **VFE** (maximum **flaps** extended speed) VMAX is depicted as the **BASE** of a **red** and **black** strip.
