Abstract

A study of the world altitude records for heavier‐than‐air aircraft homologated by the Fédération Aéronautique Internationale is interesting, and yields the information that from 1909 to 1914 the mean rate of increase of ceiling was almost 4,500 ft. per year, while from 1920 to 1936 the mean rate dropped to 1,000 ft. per year. Slumps, depressions and other financial phenomena must obviously have a repercussive influence in this particular field of aircraft development, and a pertinent example of their effect is provided by the unfortunate hiatus which occurs from 1914 to 1920, and obscures the height at which the change in rate takes place. It has been shown by Mr. McKinnon Wood, in an unpublished paper on the design of an aeroplane to reach a great height, written in November, 1931, that the power which the engine must develop at ceiling increases as the ceiling is raised, and that, in the case of a supercharged engine, the difference between the supercharged height and the ceiling of the aircraft decreases as the ceiling increases. Thus, to maintain the initial rate of increase of ceiling an accelerating rate of progress in engine design was necessary, but unlikely in view of the increasing number and difficult nature of the problems to be encountered and solved.

Abstract

A condensed version of a paper on the effect on the ultimate economics of operation of advances in specific technical areas presented at the Spring Convention held by the Royal Aeronautical Society on the Economic Factors in Aviation. CIVIL transports tend to come to the fore in discussions with an economic flavour, because the civil scene can be thought about more readily in financial terms. Money is spent in setting up and operating a transport system, and money is then recouped by charging the people who use the aeroplanes for shifting themselves and their goods. Military aircraft cannot be fitted into such a neat buyer/seller framowork — you cannot buy a ticket for a ride in a strike fighter. Even so, on the military front studies of ‘cost effectiveness’ are also undoubtedly the order of the day.

Abstract

THE design team knew that the Islander was a winner from the very first moment it leapt into the air on June 13, 1965. The reliability was phenomenal; from that first flight on June 13 to the evening of Wednesday, June 16, the aircraft completed twelve flights totalling 7 hours 25 minutes over a wide range of e.g. positions and flight regimes in order to acquire the Special Category Certificate of Airworthiness that was required for attendance at the Paris Air Show.

Abstract

THE variation of full throttle engine brake horsepower with altitude at constant rotational speed is a matter of great importance to aircraft designers and those concerned with the measurement of aircraft performance. For the former its main importance probably lies in the design of aeroplanes intended for high altitude use where accurate knowledge of the engine power available is of paramount importance in the evolution of a successful aircraft. In the measurement of aircraft performance it is necessary to reduce the observed results at non‐standard atmospheric conditions to those obtaining under the chosen standard conditions, and for this it is essential that the variation of engine power with altitude is well established.

Abstract

Purpose

The importance of critical thinking disposition (CTD) in second language (L2) university students' writing is a topic rarely discussed. The purpose of this research paper is to examine L2 university students' CTD during the writing process. Research questions discussed in this paper encompass the CT dispositions and characteristics of L2 university students in online writing environments. Measuring CTD and CTD training via online collaborative peer review were the two grounding themes of this study.

Design/methodology/approach

A five‐point Likert scale online questionnaire which included two open‐ended questions was developed to assess CTD. A factor analysis and a cluster analysis were preformed on the data. A discriminate analysis determined the number of viable clusters and a one‐way ANOVA was performed to compare differences, with qualitative interview data to supplement. The data set for CTD measurement was a matrix consisting of 27 participants and P variables.

Findings

The findings reveal that the CTD characteristics of L2s include open‐mindedness, systematicity and inquisitiveness, and low interaction/motivation.

Research limitations/implications

Limitations include a small sample size that mimics the researcher's anticipations, but the findings would be strengthened by a larger sample. A lack of sensitivity and generalisability could be corrected in the future by using broader subject matter within an online educational web site.

Originality/value

Knowledge of the CTD characteristics of L2s would allow interface designers to take into account different CTDs in developing L2 online collaborative educational web sites. This study outlines the first step in developing online collaborative educational games that allow L2 university students to improve their writing abilities by considering various CTDs.
