  2. What color are aircraft flight recorders usually painted to make them easier to find?

    Orange

    Flight recorders are usually painted bright orange, despite the nickname 'black box.' The high-visibility color helps search teams locate them after an accident.

    Easy · Also offered: Black, White, Silver · Source: Encyclopaedia Britannica, flight recorder

  3. An aircraft's black box is really two recorders. One is the flight data recorder. What is the other?

    The cockpit voice recorder

    The recorder used to loop over just 30 minutes of audio, but a 2008 rule raised the minimum to two hours after investigators kept losing cockpit sound recorded earlier in the flight. Despite the name, both recorders are painted bright orange, not black, so search teams can find them at a crash site.

  24. What are the tapered movable rails that steer a train's wheels from one line onto another called?

    Points, or a switch

    Britain calls them points and North America calls them a switch. Two tapered blades slide sideways against the running rails, so the wheel flanges are guided onto whichever route is set, and the signalling system locks them in place before a train is allowed over.

  27. Why is the right-hand side of a ship called starboard?

    It is the side the steering oar was mounted on

    Starboard comes from the Old English steorbord, the steering board. Before rudders were hung on the stern, a ship was steered with a large oar over the right-hand side, which is also why the other side became the port side: with a steering oar in the way, it was the left that had to be turned to the quay for loading.

  29. What is the name of the rotating part of a helicopter that produces most of its lift?

    The main rotor

    The main rotor generates nearly all of a helicopter's lift and thrust. The tail rotor spins too, but its job is to counter the torque the main rotor puts into the fuselage; the tail boom carries it, and skids are simply landing gear.

Hard Transport Trivia Questions

  1. What is a seaplane whose fuselage itself sits in the water, rather than being carried on separate floats, called?

    A flying boat

    A flying boat has a boat-shaped hull that provides its own buoyancy, as on the Short Sunderland or the Spruce Goose. A floatplane is carried on pontoons, an amphibian is defined by also having wheels for land, and an ekranoplan is a ground-effect craft rather than an aircraft that lands on water.

  2. Stephenson's Rocket got far more boiler heating surface than earlier locomotives from which feature?

    A multi-tubular boiler

    Rocket drew the fire's hot gases through 25 copper tubes running the length of the boiler, hugely increasing the surface exposed to the water and the steam it could raise. That, with a blastpipe sharpening the draught, won it the 1829 Rainhill Trials.

  3. What is the hinged, spring-loaded frame on the roof of an electric train that collects current from the overhead line called?

    A pantograph

    The pantograph is sprung so its carbon contact strip stays pressed against the overhead wire as the train moves and the wire height changes. A bogie is the wheeled truck under the vehicle, and a third-rail shoe collects current from a rail at track level instead.

  4. Glider pilots gain height by circling inside what?

    A thermal

    A thermal is a column of warm air rising off sun-heated ground, and a glider circles tightly to stay inside it, climbing as long as the air rises faster than the glider sinks. An inversion does the opposite, capping rising air and killing thermals off.

  5. What does drafting behind another racing vehicle mainly reduce?

    Aerodynamic drag

    The leading vehicle leaves a pocket of slower-moving, low-pressure air, so the follower meets less air resistance and needs less power to hold the same speed. Sitting in that hot, still air tends to raise engine temperature rather than lower it.

  7. Which small forward-facing tube, whose blockage by ice or insects has caused fatal airspeed errors, feeds an aircraft's airspeed indicator?

    Pitot tube

    A pitot tube points into the airflow and senses ram air pressure. Comparing that with the still-air pressure read by a flush static port gives airspeed, so a pitot blocked by ice or a wasp nest can leave a crew with badly wrong readings.

  26. What does a vehicle's differential allow the driven wheels to do when cornering?

    Rotate at different speeds

    In a turn the outer wheel travels further than the inner one, so the differential's gears split the drive between them at unequal speeds. A solid axle forces both wheels to turn together, which makes the tyres scrub and fight the steering.
