Advanced Stuff

This chapter describes some of the advanced features of vasFMC, parts of this chapter are based on Airbus procedures and features.

Important: Make sure you successfully accomplished the first flight chapter before fiddling around with the advanced features.

Prerequisites

This chapter relies on the following prerequisites:


I also recomend to use vasFMC in combination with the Project Airbus models as these were used during the development.

Airbus A/THR Mode

If the Airbus autothrottle mode is active, your throttle will behave differently to what you are used to.

First, the range of your throttle lever is divided by several detents:


Note: The percentages mentioned above may be configured in the autothrottle.cfg file located in the vasFMC configuration directory. Make sure the flightsim and vasFMC are not running while changing the values!

Second, your throttle lever is not directly connected to your engines anymore. In the Airbus mode the throttle lever commands a N1 value, thus every position of your lever is equal to a calulated N1 value. 


Third, the following facts hold:


Fourth, the following PFD thrust announcements (located on the top left of the PFD) exist:

Fifth, how to use the Airbus A/THR:


If you have trouble with the throttles (e.g. using separate throttle levers and the N1 is stuck at 40%, etc.) try the following FSUIPC tweak:

Added an extra facility for joystick calibration, in order to try to cope with some different add-on practices (notably, in this case, the Wilco A320). Normally, the 4-Throttles, 4-mixtures and 4-Prop pitch calibrations result in an output with either a range which includes the reverse zone, or, if the "no reverse zone" option is checked, a range from 0 (idle) to 16383 (max). These are sent to FS using the older "????n_SET" controls (THROTTLE1_SET, etc), since these are the ones providing the reverse zone below zero.

If you set the [JoystickCalibration] INI file parameter UseAxisControlsForNRZ to "Yes", then the NRZ (no reverse zone) option for all three axis types will use the AXIS_????n_SET controls (e.g. AXIS_THROTTLE1_SET) instead, with a range of -16363 (idle) to +16383
(Max).

Approach Phase Reset

If you activated the APPR (approach) phase via the MCDU PERF page too early or unintenional, you can reset the phase by entering a new cruise FL on the MCDU PROG page (LLSK1).

Takeoff Trim Settings

The following takeoff trim settings should be used for the stated aircraft models:

Aircraft Model Takeoff Trim Setting
MSFS Project Airbus A318, A319, A320 -1.0
MSFS Project Airbus A380 +4.5 to +5.0
MSFS Project Opensky/Freesky A330 -0.5
MSFS Project Opensky/Freesky A340 +0.5

FSUIPC Control

If you are using vasFMC with the MS Flightsimulator and own a registered version FSUIPC you can control vasFMC via various FSUIPC offsets. For details refer to the fsuipc.offsets.txt readme file located in the docs/help directory of your vasFMC installation. The file can also be viewed via the help menu of the vasFMC standalone version console window.

Checklists

vasFMC comes with fully configurable spoken checklists which are located inside the checklists directory of the vasFMC installation. The loaded checklists depends on the loaded aircraft data profile which can be selected on the MCDU DATA A/C STATUS page.
Note: At the time being, vasFMC only comes with an Airbus checklist. This may change in the future depending on user input.

To view the checklist inside the FMC go the MCDU MENU CHECKLIST page, the bottom LSKs can be used to go forward and backward in the checklists. You may also use the hidden clickspot on the FCU (right below the SPD MACH button) to advance through the checklists.
