• 2824: Add IVAO SELCAL integration
• 2825: Add support for showing COM TX flag on IVAO
• 2848: Implement route names and loading of routes by name

You can now save and load pilot routes by name. This is done either by entering the name on LSK 2L of page 1 of the FPLN page, or by entering a custom name in PILOT ROUTE LIST on LSK 6L or LSK 6R. When a name is entered on FPLN page 1 LSK 2L, if the route doesn't already exist in the PILOT ROUTE LIST, the name is simply assigned to the current flight plan. This name can then be used as the route name in PILOT ROUTE LIST by pushing LSK 6L or LSK 6R. If a route with the same name already exists in PILOT ROUTE LIST, the user is prompted if they would like to load that route instead. Loading a pilot route into the active flight plan is not permitted while the aircraft is in the air.

• 2849: Support new VATSIM departure/arrival ATISes

Some VATSIM regions have started publishing separate departure and arrival ATISes, just like some real airports do. Thus, the ATIS type selection on DATALINK > AOC CORP > ATIS now correctly attempts to pick the type-specific ATIS first, before reverting to the generalized one.

• 2860: Add volume control for FO audio

You can now control the automatic first officer's audio volume when reading checklists. The setting is located in User Settings under F/O Assists.

• 2866: Implement dynamic GPS jamming simulation

The CL650 now simulates dynamic, unannounced GPS jamming that happens in certain regions in the world, especially near disputed areas and active conflict zones. The locations of these areas are usually not NOTAM'ed, so you are encouraged to be on the lookout for potential issues with GPS reception in areas such as: - the Middle East - Eastern Europe - South China Sea - parts of Mexico Please note that these locations aren't hard-coded into the simulation. They dynamically change over time and needn't be active at all times. We can also add new areas post-release, and already have plans to add NOTAM'ed (scheduled and published) GPS outages. The simulation works by performing radio signal propagation modeling (including terrain masking) between the aircraft and every jamming station. If the signal levels of the jammer overpower the GPS satellite signals at the aircraft's position, the GPS position integrity will gradually degrade, until it is completely lost. You will then need to revert to inertial navigation and utilize radio or manual position updating. For now, we have chosen to avoid simulating GPS position spoofing, however. Please note that not all approach procedures can be flown without GPS available. Consult the approach procedure charts for required navigational sensors, as well as required navigational performance (RNP). This can then be cross-checked against the EPU value (Estimated Position Uncertainty) on the PFD as well as on the FMS PROG 2/2 page. Without GPS available, the FMC will attempt to use any enabled radio sensors (VOR/DME or DME/DME) as a source of position updates. Thus, flying an RNP 1.0 or sometimes even an RNP 0.3 approach might still be possible, provided that the approaches do not hard-require a GPS or GNSS sensor be available, and that a suitable position-updating navaid is available within range. For study purposes, the status of the jammer stations can be seen in the Study > GPS > GPS Jamming Stations window.

• 2869: Implement TOC and TOD display on MFD data window
• 2927: Implement manual FMC position updating

Dovetailing with the above GPS jamming functionality, the FMC now fully implements manual position updating. It is, admittedly, a very rarely used feature with GPS available, however, it does manifest in one useful way when in a GPS-denied environment. On departure, you will now have a "RWY UPDATE" prompt available on the ACT LEGS page on LSK 6L while the aircraft is on the ground. This can be used to manually update the FMC position to the runway threshold prior to takeoff, thus nulling out any positional drift due to purely inertial operation.

• 2953: Add search function to failure manager
• 2954: Add tooltips with descriptions to the Bleed study screen
• 2955: Add ASU engine parameters to the Bleed study screen
• 2963: Add ADG and nose gear door pins

The aircraft now contains a beautiful 3D model of the air-driven generator (ADG, aka RAT on other aircraft), and together with that it brings an additional set of ground pins in the nose gear bay that must be manipulated by the pilot prior to and after a flight. The ADG pin is located on the right-hand wall of the nose gear bay, in the forward section. This pin locks the ADG in the stowed position, to prevent inadvertent ADG deployment while on the ground (restowing the ADG requires qualified maintenance personnel be called in). The second new ground pin is for the nose door and is located on the same right-hand wall of the nose gear bay, but more towards the aft section. For personal safety of ground crew while in the nose gear bay, the nose door is pinned, thus preventing any chance of the door closing and injuring personnel working there. This pin is typically installed after a flight and removed before a flight. These two additions complete the full set of 5 ground pins that are used in day-to-day operations.

• 2988: Elevator control system is missing gain change mechanism from control column, causing over-controlling at higher speeds
• 3121: Implement variable pitch feel based on stabilizer trim position

We've reworked the pitch feel to replicate the variable-rate pitch feel of the real aircraft. Unlike other aircraft where the pitch feel is based on airspeed, the Challenger uses the stabilizer trim position as a stand-in for airspeed. The pitch response near the center gets more desensitized the more nose-down elevator trim is applied (implying flight at a higher speed). There is also a fixed "curve" that gets applied near the neutral point. This comes from a mechanical part of the elevator mechanization called the gain-change mechanism. This is more-or-less fixed and is always applied on top of the variable pitch feel from the stabilizer trim. We recommend removing any kind of curves you have applied to your joystick or yoke and try to get used to the new out-of-the-box feel. If you have a force-feedback yoke with controllable force intensity (such as a Brunner FFB yoke), you can disable the trim-dependent pitch feel in the User Settings under the User Interface tab. You can then replicate it in a proper FFB way by gradually increasing the force needed to move the elevator as elevator trim goes from 5.0 to 1.25 (5=lighest, 1.25=heaviest). Outside of this range, the force should be constant, as the real pitch feel mechanism doesn't change force intensity outside of these ranges either.

• 2908: Adjust electrical loads of components to be slightly more realistic
• 2910: Refactor NAV-to-NAV transfer to avoid LNAV capture when APPR LOC is armed

The NAV-to-NAV transfer system behavior was changed to behave more like the real airplane. When the aircraft is being vectored and utilizing HDG lateral mode, pushing APPR with a NAV-to-NAV approach loaded (e.g. an ILS) will no longer capture the LNAV path if the airplane happens to come close to the FMS path. Instead, *only* the armed APPR LOC mode will capture when the localizer begins to center. This helps prevent an inadvertent capture of the FMS path that might no longer be applicable. On the flip side, this means you will not be able to perform high-angle LOC captures (>45 degrees) by first capturing the FMS path in APPR LNV and then transitioning to APPR LOC. To perform a high-angle intercept with an intermediate step through the LNV mode, first push "NAV" on the FCP to arm the regular LNV mode for capture. Wait until the mode captures the FMS path and only then push the APPR FCP button to arm NAV-to-NAV transfer onto the localizer.

• 3036: Remove landing data that doesn’t exist in real box and add supplemental data message

We've made fixes to the APPROACH REF computer to bring it in line with the quirks that the real avionics has. One of those particular gotchas is that you will no longer be able to compute an Actual Landing Distance (ALD) value when the runway condition is set to WET on page 1/4. Instead, the box will simply post an amber '?' for the ALD value and you will get an amber PERF OUT OF RANGE message. For regulatory reasons, when the runway is wet, the only value to be used is the factored Landing Field Length (LFL). You can switch the ALD display to LFL by typing 'L' on the scratchpad and pushing LSK 4L on APPROACH REF page 2/4. This will remove the caution message and the FMS will show the factored (1.15x) landing field length instead. However, on the flip side, when the runway condition is set to any of the other contaminated settings (i.e. SLUSH-WATER, LSNOW, CSNOW or ICE), LFL becomes unavailable (and will post a PERF OUT OF RANGE message), and you will need to use ALD instead (place an 'A' on LSK 4L to switch to ALD display). The reason here is that there is no landing distance correction factor published for these contaminated runway conditions, so you will want to enter your own into LAND FACT on LSK 2L. An additional gotcha is that when the runway condition is set to anything other than DRY, the FMS will post a white SUPPLEMENTAL DATA message. This message cannot be avoided, and is intended to emphasize that the FMS isn't using data from AFM Section 6 (Performance), but instead from AFM Supplement 2 (Operation on Wet and Contaminated Runways).
