Record 2 2020-11-18

English

Subject field(s)
  • Skydiving, Paragliding and Hang Gliding
CONT

SPIRAL DIVE. When you turn a series of tightening 360s the paraglider will enter a spiral-a highly banked turn with rapid height loss. The longer you hold the inside brake on, the faster the turn becomes. Safe descent rates of 8 metres/second(500 ft/min approx.) are possible in a spiral dive, but at these high speeds and G-forces it is easy to become disorientated, so you must pay particular attention to altitude.

CONT

It is possible to achieve sink rates as high as 5 or 6 metres/second by linking 360° turns [i.e. in a spiral dive - although the French says linking turns].

OBS

360° turns: term used in the plural.

French

Domaine(s)
  • Parachutisme, parapente et deltaplane
CONT

On parle de 360 engagés quand le pilote, à haute altitude, engage un virage à 360° et le poursuit jusqu'à faire 3 ou 4 tours, ce qui l'amène à réaliser une spirale. C'est une technique qui nécessite tout de même une maîtrise du vol. La force centrifuge augmente à chaque tour et n'est pas à négliger, ni le taux de chute qui peut dépasser les 10 m/s.

CONT

Au cours de 360° enchaînés, des taux de chute de l'ordre de 5 à 6 m/s sont atteints.

OBS

Termes utilisés au pluriel.

Subject field(s)

CONT

A full autopilot option has been added, including altitude hold, heading select/hold, very high frequency [VHF] omni-directional radio range localizer(VOR/LOC) track, instrument landing system(ILS) track, and global positioning system(GPS) steering.

CONT

The localizer transmission, at very high frequency [VHF] frequencies (108 -122 Mhz), provides information to the aircraft as to whether it is flying to the left or right of the centre line of the runway it is approaching. The localizer receiver output is proportional to the angular deviation ... of the aircraft from the localizer beam centre line which in turn corresponds with the centre line of the runway.

Subject field(s)
  • Flight Instruments and Equipment (Aeroindustry)
  • Aircraft Piloting and Navigation
CONT

The turn coordinator is really two instruments. The gyro portion shows the aircraft’s rate of turn –how fast it’s changing direction. A ball in a tube called the "inclinometer" or "slip/skid indicator" shows the quality of the turn –whether the turn is "coordinated."

CONT

Trimming Technique. Set thrust symmetrically with autopilot in altitude hold and speed stabilized. Disconnect autopilot and observe response. If aircraft does not hold altitude, trim the stabilizer to correct the mistrim. Manually fly the aircraft and hold wings level. Center the sideslip indicator("ball") using rudder trim. Trim the ailerons hands off as required to maintain wings level.

CONT

StratSat provides a geo-stationary platform at 20 km altitude capable of remaining on-station for up to five years. Payloads include high speed Internet services, direct broadcast TV, mobile telecommunication, etc. The envelope operates as a super-pressure hull(i. e. with no ballonet pressure control system). The hull will be of laminated fabric construction with Tedlar/Teflon, helium/weather barrier developed from AT-10/04. Multiple catenary curtain system supporting a payload module enclosed completely by the envelope. [The] payload module... comprises a single structural module with an externally mounted payload/mission system. The payload module provides a home for all of the airship's primary systems except for the propulsion system. The systems are close packed within the highly insulated module ensuring efficient heat and energy management. The payload module is pendulum stabilised within the envelope. The solar array provides the sole source of renewable energy for the airship. The array is placed over the upper quarter of the hull and extends over approximately three-quarters of the length of the craft. The array can be realigned to the daily sun location/angle by the roll rotation of the whole airship. The energy collected by the solar array is stored for use during the night in the series of batteries. Located in the stored for use during the night in a series of batteries. Located in the payload module, the batteries run the propulsion system, airship services and provide power to the mission system for up to 14 hours(during winter). The airship is propelled and steered by means of a ’Contra-Rotating Coned Rotor’ mounted on a tailcone at the rear of the envelope, as a part of a compound propulsion system. The unit provides longitudinal thrust(to counter the prevailing stratospheric winds) and lateral force(for manoeuvering) to enable the airship to hold station within a 1 km cube. The airship will be equipped with a multi-channel Flight Control Sy

  • Weather Stations and Meteorological Instruments and Equipment

DEF

An electronic hand-held weather recording device used, for instance, by car racing teams, sailors, farmers, outdoor and weather enthusiasts.

CONT

... hand held weather stations take about every weather factor into consideration. ... Very sophisticated ones not only measure weather conditions every second but make E.T. or throttle stop predictions every 4 seconds. A sophisticated drag racing weather station will allow you to store data on as many as 256 previous runs and performs an analysis to give you a prediction based on the weather conditions instantly. It can keep and use separate databases for separate vehicles, tracks, or classes. Some of the really sophisticated stations have a prediction deviation function [which] gives a reliability value of the prediction. It gives you a margin of error based on the information in the database that you chose. Within the last few years, windmeters have been added to the weather station box of tricks.

CONT

The Kestrel line of wind meters or anemometers... in less than 60 seconds, provide the answer to the major spraying season question that haunts producers each morning :"How windy is it?" The Kestrel 1000... gives a fast answer to wind speed average and gusts.... the model 2000 will add temperature and for those really cold days on the sprayer, add wind chill to that list. The 3000 adds humidity, dew point and heat stress index.... But for an all out weather station you can hold in the palm of your hand, the Kestrel 4000 provides all of this, in addition to wet bulb, altitude, air density and barometric pressure. Most importantly, 250 of these readings can be recorded in the device's memory and later transferred to the farm computer.... Michael Naughton of Nielsen Keller-man said the company released the 1000 in 1999 with the intention of it being a tool for sailors and outdoor sports and weather enthusiasts. "Farmers are turning out to be a really big part of our business. The 4000 is really popular with them. We were surprised by the demand for little hand-held weather stations, "he said.

CONT

During a turn the nose of the aircraft is continually pitching up. Your pitch gyro will see this and attempt to stop it. This results in the nose dropping, and a decrease in altitude. Your pressure sensor will sense this loss of altitude and attempt to correct it. So, effectively, the gyro and pressure sensor will be working against each other(slightly) and the end result is that your plane will not hold the desired altitude, but one slightly lower than the desired altitude. This is especially true in the early portions of the turn.
