The Rake's Progress and other theatre design challenges
Elizabethan audiences sat between the legs of those behind. Today’s audiences expect leg room and clear sight lines.
If a theatre technician from the 1700s were able to travel back in time and wander around today’s theatres there would be much to astonish but much that would also be familiar. For example, the format of conventional spotlights (reflector, light source, lens, and colour) was established in the 1500s and, the basic geography of a theatre building has also changed little over the centuries.
However, one significant change in recent decades has been the increase in the angle of the rake of the stalls. In theatres built around the world in the early 1900s the angle of the stalls rake was typically in single figures, today the angle of the rake is more likely to be twice this amount. The result is improved vertical sightlines for the majority of the audience, an expectation reinforced by people at home tempted by large screen televisions viewed from comfortable loungers. However, a higher rear stalls also means a higher circle but roof lines are not significantly higher today because few new theatres contain the third gallery as most did in the past.
Gulfstream Releases Update to Planebook Ipad App
2011.“Our customers enjoy the convenience of using our operating manuals on the iPad and receiving automatic updates,” said Bill Colleran, director, Technical Publications, Gulfstream. “This update incorporates a number of improvements that came from their feedback, including landscape and portrait orientations, AirPrint compatibility and search features. We think our customers will be pleased with the result.”
Other new features include a document selector, history window, bookmark navigator, manual reorder feature, highly visible battery percentage indicator, better aircraft subscription organization and an improved help file.
The PlaneBook app provides pilots easy and immediate access to critical flight information and aircraft-specific documents, such as the Airplane Flight Manual, Operating Manual, Pilot’s Checklist and the Quick Reference Handbook (QRH). The electronic version of the QRH, which includes emergency flight procedures, serves as the master document that links to all other documents for easy cross-referencing.
PlaneBook also allows pilots to create and add their own content and tailor the app to their particular flying habits or preferences. In addition, since documents and manuals are downloaded straight to the iPad, users will have offline access to all of their important information. A “History” feature gives pilots even quicker access to the documents they frequently use, and instructional videos for each of Gulfstream’s aircraft, as well as latest news from the company, are available through the app.
