Henrik-Jan van Veen has carried out a great deal of research into spinning. This is especially true for “graveyard spins”, the term for what happens when fighter pilots get so disoriented they miscalculate how to get their plane back on course. They can end up in a dangerous and often fatal spin. Van Veen works at a research lab run by the Netherlands Organization for Applied Scientific Research, the TNO. The range of research covered by the TNO is vast, and it sees itself as a practical problem solver. And for the Dutch air force, the graveyard spin is certainly a problem that needs solving. Van Veen’s specialty is “vibrotactile devices”, which use vibrations to convey information. His latest project is a vest studded all over with small discs that can each vibrate independently. In a test room, a pilot is strapped into a seat in a “cockpit”. At the push of a button, the lights go out and the chair starts spinning. After a while the chair is stopped. “He’ll think he’s spinning the other way now”, says van Veen. The pilot is told to correct the spin, but instead, he overcorrects massively, and the chair begins spinning again. In the next test, the pilot dons van Veen’s vest and is told that the patch of the vest that is vibrating will indicate the direction he should force the joystick to correct a spin. This time, when the chair stops spinning the pilot manages to keep the seat still. Van Veen thinks the vibrotactile vest could do more than save the lives of fighter pilots. He’s now working on linking the system to a GPS receiver so that tourists in a foreign city or blind people in an unfamiliar environment can use the vest to find their way around.
61. It is clear from the passage that the vibrotactile vest ----.
A) has contributed significantly to environmental researchB) could be developed to serve a variety of purposes
C) has been in use in military aviation for many decades
D) is the product of an expensive research project undertaken by the Dutch military
E) could be used to transmit secret military information
62. It is understood from the passage that, because spins in fighter flights can be fatal, ----.
A) they are referred to as “graveyard spins”B) van Veen has been testing a number of devices that could prevent spins
C) the TNO is making spin-prevention devices a major research project
D) many aircraft have been indefinitely grounded
E) all pilots are required to wear a vibrotactile vest
63. We understand from the passage that the Dutch research centre, the TNO, ----.
A) works in very close association with the Dutch armed forcesB) oversees all major research projects being carried out in the country
C) has put a lot of pressure on van Veen to extend the uses of vibrotactile devices
D) encourages the application of research for the solving of problems
E) puts safety devices high on its list of priorities
64. It is clear from the passage that van Veen’s immediate purpose in developing the vibrotactile vest is to ----.
A) help fighter pilots to calculate their course more accuratelyB) warn pilots in advance that a spin is building up
C) help the blind find their way about
D) make it possible to reduce the amount of fuel used by aircraft
E) enable fighter pilots to get over the effects of aspin and thus, avoid a crash
