Описание: В 1966 году в Национальной библиотеке в Мадриде были обнаружены два манускрипта, написанные Леонардо. Когда-то они не были учтены при каталогизации, и об их существовании не было известно. Этим двум манускриптам дали условные названия «Мадридский кодекс I» и «Мадридский кодекс II».
«Мадридский кодекс I» состоит из 192 листов 1490—1499 годов написания, содержащих изображения различных механизмов и изложения теории механики. Хотя работа и посвящена механике, в ней есть заметки по астрономии и по оптике.
«Мадридский кодекс II» был создан Леонардо в 1503—1505 гг. и состоит из 158 листов. Он собрал исследования в области геометрии, такие, например, как «квадратуры круга». Кроме этого, в нём содержатся работы по перспективе и оптике. В книге можно найти эскизы морских и топографических карт, рассматриваются проблемы военной техники и архитектуры. Самое интересное в этом кодексе — неосуществлённый проект изменения русла реки Арно, эскизы фрески «Битва при Ангиари» и конного памятника Франческо Сфорца.

Sample text

In the Millsian world of CRM that they collectively conjured, the demon of unpredictable action in haste, fear or boredom is reduced to a problem of information transfer. Inquire when you don't know, advocate when you do, resolve differences, allocate resources - the psychologists urged a new set of attitudinal corrections that would soften the macho pilot, harden the passive one and create coordinated systems. Information, once blocked by poisonous bad attitudes, would be freed, and the cockpit society, with its benevolent ruling captain, assertive, clear-thinking officers, and alert radio-present controllers, would outwit disaster.

Among other difficulties, the airplane was oscillating longitudinally with a period of 40-60 seconds. In normal flight the plane will follow such long-period swings, accelerating on the downswing, picking up speed and lift, then rising with slowing airspeed. But in normal flight, these variations in pitch (phugoids) naturally damp out around the equilibrium position defined by the elevator trim. Here, however, the thrust of the numbers one and three engines which were below the center of gravity had no compensating force above the center of gravity (since the tail-mounted number two engine was now dead and gone).

What is demanded of a pilot - a pilot on any flight using V I as a go-no-go speed - is a judgment, a protocoldefying judgment, that V I has been reached "early enough" (determined without an instrument or exterior marking) in the takeoff roll and without a significant anomaly. )l3 The NTSB report "knows" that there is a problem with the VI rejection criterion, though it knows it in an unstable way: It is not necessary that a crew completely analyze a problem before rejecting a takeoff on the takeoff roll.
