AirplanePDQ November 2001 - A Release Notes

This update should be applied to the November 2001 Release only.  If you have a previous version installed, please download the full release file instead of the update.

Installation Instructions

1. Download the update file Update-1101-A.exe and save it to your local system.
2. Exit from AirplanePDQ if you have it running.
3. Once the download is complete, double click on the Update-1101-A.exe file icon.
4. A window will appear titled "AirplanePDQ November 2001 - A Release Update". Check the folder name in the box "Extract to:" to make sure that it is the same folder name where you initially installed AirplanePDQ and correct it if necessary.
5. Click on the button labeled "Extract".
6. The installation is complete and you can run AirplanePDQ normally with the new updates.

New Features in Release

	Added engine templates for Jabiru engines
	Added support for new X-Plane 6.16 file format

	Added support for saving view parameters when switching between views
	Added aircraft length and height to the design summary report

Automatically set drawing limits to extend beyond the edges of the aircraft

Issues Fixed in Release

	Made trim algorithm more robust to better handle trim calculations at low speeds around stall
	Corrected pitching moment calculation for control surfaces
	Modified fuselage pitching moment estimation algorithm
	Significantly improved import and export of X-Plane files
	Corrected handling of large dihedral angles (>135 deg)
	Corrected handling of nacelle editing
	Corrected range calculation which used default prop efficiency instead of calculated prop efficiency
	Corrected handling of seat positions so seat positions are not reset after reloading a drawing
	Fixed problem with changing taper ratio in the side view
	Fixed issue with licensing code for time zones far from GMT
	Fixed accumulation of multiple CG indicators and CG limits boxes
	Fixed nacelle geometry export problem with X-Plane v5 format
	Fixed typo in design check report--If vertical stab was too large, report said to increase size instead of decrease size
	Fixed run-time errors at large subsonic speeds
	Corrected handling of control surface editing if control is moved beyond limits of wing
	Restricted engine pitch to +- 30 deg to avoid inaccuracies at large pitch angles
	Corrected handling of stabilators in CG limits check.  With a stabilitor, the software now deflects stabilator at alpha clmax for the stabilator instead of just the default maximum elevator deflection angle
	Corrected tooltips for checkboxes on several worksheet
	Corrected handling of international settings (e.g. "." vs "," for decimal sep) in file saving.  Now uses US settings regardless of locale settings and thus files can be transferred between users in different countries
	Now drawing ground line for both tricycle gear and taildragger designs
	Changed thrust moment calculations to use the propeller reference position instead of the engine reference position
	Corrected vertical tail volume coefficient for dihedral
	Corrected handling of vertical tails with dihedral
	Corrected calculation of wetted area for twin tails
	Corrected minus sign on tail volume coefficients for canards
	Fixed run time error that occurred if prop tip speed exceeded sonic velocity
