Version 1.2 XP12 (July 16th 2023)
- We added a basic autopilot [even though the real T-6A does not have one] for our customers who wanted something to hold the airplane at altitude and on course during long cross country flights.
- A separate Autopilot User Guide pdf is provided in the T-6A root folder / manuals sub folder for customer to study.
- We improved the unique T-6A integrated Traffic Advisory/Vertical Speed Indicator to bring it even closer to the capabilities of the real thing by adding your altitude / AI target plane altitude delta reporting in the upper right corner of the display.
- New optional pop up/out radios and engine data displays. The GPS navigation radio, Radio Management Unit (RMU) and the three engine data (primary, alternate and systems) electronic displays can be popped up/out from the panel and resized/repositioned. After you pop them out once, resize and position them to your liking, then close them they remember your setting and popout the next time exactly where and how you set them. Neat, and they are VR compatible.
- New T-6A_vrconfig.txt file in T-6A root folder. It presets the pilot POV to a point recommended by one of our VR capable customers.
- Main landing gear wheel brake fade monitoring annunciator built into the Engine System Display (ESD). This warns of brake fade due to high speed, continuous or heavy brake use that can lead to HOT BRAKES and eventual brake failure.
- 41 page, updated X-Pane 12 version 1.2 User Guide. Like military -1 Flight Manuals we use solid black, vertical bars to highlight new information in our User Guides. So, if you are familiar with the previous versions of the T-6A User Guide (XP11 1.0, 11 1.1, XP12 1.0) these bars help guide you to the newest information. Otherwise, we highly recommend you read the whole UG before attempting to operate this model, because the entire cockpit and basic operating principles are closely modeled on the real thing.
Version 1.1 XP12 (June 1st 2023)
- Native support for M1 / M2 Mac
- New longer 40 second engine start spool time as per actual T-6A PT6A turboprop engine specs
- Added TACAN nav station tuning capability to Nav radio and needle display on EHSI
- Note: Military "Tactical Air Navigation" (TACAN) capability was added to the sim by Laminar Research in X-Plane 12
- Improved canopy lock/unlock annunciator logic
- Increase aircraft roll rate
- Updated T-6A User Guide, new version 1.1
Version 1.0 XP12 (March 1st 2023)
Version 1.1 XP11 (December 6th 2022)
1. FIRE 1 can now be tested with only the Aux Battery switch ON for ";over the rail"; checks.
2. Increased available elevator pitch trim after US Marine Corp pilot feedback, which led to the need for...
3. Revised takeoff trim settings for engine running start and optional TRIM annunciator.
4. Robust low speed flight model improvements for more accurate performance in approach and stall speed ranges, as a result of ...
5. New custom Pilatus airfoils with optimized high and lo Reynolds numbers versions, which led to the need for ...
5. Recalibrated Electronic Air Speed Indicator (EASI) for improved accuracy throughout the needle's sweep range, which led to the need for ...
6. Revised T-6A User Guide has additional information for flying different approach and landing methods (Air Speed or AOA), which resulted in ...
7. Default AOA indexer colors are now the US Navy style green, yellow, red from top to bottom.
Note: "Navy style"; AOA approaches are flown from ";behind the power curve"; so the aircraft nose is decidedly nose high during the approach compared to Air Force style approaches flown referencing airspeeds. When behind the power curve aircraft rate of descent is controlled with power.
Note: With Options ON you get an enhanced Air Force style red, green, yellow top to bottom indexer. This eliminates the need to manually edit a script file to choose an indexer style, though if you want the enhanced version as your default you can edit aoa_indexer.lua script; lines 100 and 215. Line 100 edit if(get(as_switch,16)==0) and make it ==1, and line 215 edit if(get(as_switch,16)==1) and make it ==0 8. AOA indexer left to right twist rotation increased from 45 to 180 deg. It was 6 oclock to 4:30, now it twists from 9 oclock to 3 oclock.Note: the AOA indexer is twisted all the way left or right before formation flight to gauge distance on the flight lead during join up. Ref AETC MAN 11-248, Table 9.3 Range Estimation.
9. High altitude, max speed flight model improved by increasing engine critical altitude from 16,000 to 17,500 ft MSL.
10. Based on further pilot feedback, slightly increased propeller minimum pitch in order slightly reduce airborne idle prop drag and ...
11. Implemented ground (60%) and flight (67%) idle modes as per 1T-6A-1 Flight Manual to improve ground taxi and approach handling characteristics.
12. Re-coded the ";tad"; lua script to enable pilot rudder trim input AND dynamic rudder trim compensation by the TAD correction formula.
Note: See 1T-6A-1, page 1-43 TRIM AID DEVICE (TAD)
