Σελίδα 270 - It is measured in a plane parallel to the plane of symmetry. drift angle, the horizontal angle between the longitudinal axis of an aircraft and its path relative to the ground.
Σελίδα 120 - The dash on the beginning of the hour (shown as 59 minutes 60 seconds) is much longer than the others, ie, 1.3 seconds. In all cases the beginnings of the dashes indicate the beginnings of the seconds, and the ends of the dashes are without significance. It will be noted that the number of dashes sounded in the group at the end of any minute indicates the number of minutes of the signal yet to be sent.
Σελίδα 1 - A SPHERE is a solid, or volume, bounded by a curved surface, all points of which are equally distant from a point within, called the center.
Σελίδα 267 - Authority for the rapid collection and distribution of weather information. Such a communication system is essential for an effective airway weather service. The weather observations are collected in groups. The reports of each circuit are then automatically relayed to such other circuits as require them. Complete weather...
Σελίδα 267 - Complete weather information is thus made available at every important airway terminal as soon as the sequence collections and relays have been completed, which is only a few minutes after the meteorological observations represented by the report have been made. The reports are broadcast by radio to pilots in the air, posted on Weather Bureau bulletin boards, entered on meteorological charts and maps, and disseminated by telephone and interphone systems as they are received, so that pilots and air-line...
Σελίδα 12 - Sectional charts, of the entire United States, in 87 sheets, at a scale of 1 : 500,000, or about 8 miles to the inch (fig.
Σελίδα 178 - A'B'C'DE show paths of rays of light through the prisms for two different positions. 2. The objective lens causes the rays of light passing through it to come to a focus and form an image of the observed body at the bottom surface of the field lens. 3. The function of the astigmatizer lens has been explained above. Whenever the lens is thrown out of the optical path, a parallel plate glass is substituted to compensate for a change in focal length.
Σελίδα 70 - X 1 up. When they reach a neutral position (both half open) the air relay and oil valve are centered and servo piston movement away from neutral is stopped. Now consider that the control surface movement which the servo has been producing has been bringing the aircraft back to level flight. As the plane continues in toward level the air pick-offs which have been driven ahead of the gyro box pass beyond the neutral point and begin to cause servo movement in
Σελίδα 267 - The observations generally consist of ceiling (height of cloud base or overcast above the ground in feet) ; sky conditions; visibility in miles; weather conditions (including precipitation, squalls, etc.); obstruction to vision (fog, haze, etc.); temperature; dew point; wind direction and velocity; barometric pressure; pressure change tendency; amount, type, and direction of clouds; and miscellaneous information (such as thunderstorms, line-squalls, etc.).
Σελίδα 130 - Z" type marker beacon. A. An "M" type marker beacon is a low powered omni-directional radio station transmitting a characteristic signal such as "H" (....) every ten seconds on the same frequencies as those of the adjacent radio ranges. This station has a range of from three to ten miles, depending on the weather conditions and the type and condition of the receiving equipment. A "Z" type marker beacon is an ultrahigh frequency radio marker transmitting a constant signal in the shape of an inverted...
