Update! MSFS2020 - Cessna 152X Improvement Mod - V.0.9.4



Installation

Place the "C152X" folder in your community package folder.

The installation does not create a new aircraft selection in the simulator. The modifications are applied to the Textron Aviation Cessna 152. Once the package is installed in the community folder, selecting this aircraft in the sim should load the C152X Mod aircraft.

Note that none of the base files for the default aircraft are directly modified in any way. Removing the "C152X" folder from the community package folder should remove and deactivate the C152X Realism Mod.

    V.0.9.4

    Firstly I would like to thank each and every one of you for patiently waiting for this release! Over the last couple of weeks the weather here in the UK has been, interesting, which has caused a lot of extra time required focusing on my full-time job, throw Christmas/New Year into the mix and well, all I can do is apologise! But here we have it! Changelog:

    Flight Model changes

    This should now more closely reflect the real world aircraft!

    More work is still being done to completely fine-tune the flight model!

    Utilising the new RPM Gauge, this was released in V0.9.3b but I forgot to mention it!

    Aircraft Geometry updated!

    Hopefully, a fix for Saitek Panel users, causing a weird sound bug when starting the engine!

    Until next time, see you soon and thanks again for understanding the reasons for the delays!

    V.0.9.3.b

    Due to the recent 1.12.13.0 release of MSFS and the amount of changes Asobo made to the default C152 (Which this mod builds upon) that caused serious issues within our addon, we have taken the decision to temporarily remove the Flight Model changes from this build.

    This was a difficult decision, however, in the interest of making a "quick hotfix" to get the rest of the addon working as it should, it was necessary!

    It isn't all bad news! - This does mean that we get a chance to completely rethink our approach, after learning so much from the past versions, meaning we will be able to deliver a more realistic, higher quality & stable flight model in our next release!

    I hope you understand and I really appreciate your patience! I want to provide you with the spectacular addon and wan't happy to release a flight model that had a number of big issues!

    Myself and the Beta Testing team are working hard to get the next update ready! I will hopefully have an update for you around New Years Day!

    I wish you all a Merry Christmas and I will update you soon!

    • Fuel consumption adjusted.
    • Long Range Fuel Tanks 37.5USG total useable. See note below.

    • OAT thermometer now operates regardless of the position of the master switch.
    • The overhead (Dome) light can now be dimmed by the dimmer knob below the pilot control yoke.
    • The NAV CDI gauges completely revised:
    • CDI gauges now respond correctly to: User selected On/Off state of corresponding NAV/COM Radio.
    • CDI gauges now respond correctly to: Power state of corresponding NAV/COM Radio.
    • CDI gauges now power off when Avionics Power (Battery Master Switch) switched off.
    • CDI gauges now power off when the applicable NAV/COM Radio is turned off using the Volume/Off knob.

    • ADF Needle is driven to point to the selected NDB station only in ADF Mode. (Note that currently the ADF Mode Knob defaults to BFO Mode and must be manually rotated to ADF Mode.)
    • ADF Needle remains in current position in ADF Mode when no signal received from an NDB on the currently selected frequency.
    • ADF Needle remains in current position in BFO and REC Modes.
    • ADF Needle is slewed in a clockwise direction while ADF Mode Knob held in TEST position. When released, the ADF Mode Knob spring returns to ADF Mode.
    • ADF Needle remains in current position when ADF Radio is turned off using the Volume/Off knob.
    • ADF Needle remains in current position if battery discharges and voltage level to the radio drops below the minimum required for operation.
    • ADF Volume and ADF Mode Knob position state now loaded from .flt files. ADF Mode knob defaults to 'ADF' position.

    • NAV Ident / COM Test remain out when pulled.
    • Audio Selector (KA134) completely revised. Various states now loaded from .flt files.
    • Buttons now remain depressed when selected.
    • MIC1/MIC2 selects either COM1 or COM2 as active transmitter.
    • BOTH allows selection of reception on both COM1 and COM2.
    • NAV1, NAV2, ADF (AOE wtf?) etc select ident audio.
    • MKR selects Marker ident audio. Note: My testing so far indicates audio received (and light flashes) from Middle Marker, however Outer Marker light flashes but no audio heard. Not sure if this is a sim issue.
    • DME, SPKR buttons now operate but are currently non functional.

    Notes:

    The default aircraft panel has a Tachometer with a 2700RPM redline. As a result I have taken the decision to model the C152 with the corresponding and slightly uprated 115HP engine. (It is essentially the same engine as the 'standard' C152 Lycoming engine with 110HP/2550RPM redline, with a few extra horsepower gained from the additional RPM. The standard performance charts eg cruise power settings etc will still be valid. The extra horsepower means slightly better takeoff and go-around performance and a slightly higher service ceiling. The current version tested in the sim has a service ceiling around 15,500ft.)

    The default aircraft panel depicted fuel gauges for Long Range Tanks (37.5USG) but the sim data was for Short Range Tanks (24.5USG useable). Again I have taken the decision to model the Long Range Tanks. This now gives the aircraft a nearly 9 hour endurance and a range of up to 670 nm. This makes the aircraft much more capable of long range flights in the sim, and I think much more useful. (Round the world type flight capability. :))

    I have not tested this Mod in any of the activities, lessons etc that may utilise the default aircraft. I can't guarantee that it will not cause issues in some of these situations. Use at your own risk. :)
