Computing True Airspeed

The spreadsheet AirspeedFromThreeTracks.xls Computes the actual true airspeed of a plane given three GPS tracks taken at the same airspeed. Given three GPS tracks at the same airspeed you can compute a complete solution for the heading on each track and the TAS. The spreadsheet contains actual data taken at low altitude in Lancair IV-P N776CM. Additional data will be added to the spreadsheet as it is collected for other altitudes.

The method came from a good discussion by Doug Grey which used to be found at: https://www.ntps.edu/images/stories/documents/tas_fnl3.pdf, (local copy).

Applications and Support

Soaring applications are listed with other applications supported on the Dragonnorth resources page.

LODA for Training in Experimental Aircraft

LODA for Michael Newman to give Experimental instruction

LODA for Training in N776CM

After the FAA revoked the EAA training exemption at Oshkosh in 2009 members of LOBO were discussing with the FAA how to enable training in type for people who were building new homebuilt kits. This discussion evolved toward the end of 2009, resulted in discussions between Michael Newman and the Boston FSDO in early 2010. The discussion continued in meetings with the FAA at 2010 Sun N Fun. Shortly after that meeting Michael continued the discussions with the Boston FSDO, getting their advice on how to submit a LODA application for this training. This simple Application Letter was submitted in May 2010 along with the LOBO FITS Approved Training documents. Over the remainder of 2010 there were many more discussions over details. The FAA revamped the process of issuing LODA approvals over this period. In January 2011 the actual LODA Approval for N776CM came through.

Glider Speeds to Fly

The speeds in these tables were establish by graphical construction from the polar show in the glider's manual on the GBSC web site. Take them with a grain of salt, the speeds feel more like MC 1 numbers.
