What is
Rallying :
Rallying is a motor sporting event which
primarily involves a vehicle, a driver, and a navigator. Some events also allow
passengers to sit in the vehicle. Rallying is driving under prescribed speed
and through prescribed routes only. Somewhere in the route there are Time Controls (TC) strategically placed
by the Organisers, but undisclosed to the competing
vehicles. At these Time Controls the Marshal
records the time of touching the wheel of the car with the rope laid down on
the road. The time is also endorsed in the Time
Control Card (TCB) of the competitors.
Enroute the Organisers often strategically place Passage Controls (PC) to ensure that the competing vehicles are
traveling through the prescribed route. At Passage Controls time is not
endorsed but often the Marshals put their signature on the Time Control Card
(TCB).
Finally these timings are used to calculate
penalties incurred by the Competing vehicles. The vehicle with the lowest penalty
wins the event. In rallying, the skills of both the Driver and the navigator
are tested.

Requirement
for participation :
Any person over 18 years and with a valid
Driving License can participate in Rallying. He has to have a navigator who
will guide him through the event. Certain documents and certain other
guidelines as laid down by the governing bodies needs
to be followed by each competing vehicle.
Primary
documents required :
§ Entry
Form
§ Vehicle Registration Book.
§ Tax Book (Tax token)
§ Insurance Documents (Special Rally cover
insurance)
§ Driving License.
§ Authority letter from owner of the vehicle
if First Driver is not the owner of the competing vehicle.
§ Pollution Under Control Certificate (PUC)
§ FMSCI
License
§ Blood
Group Certificate
§ Photographs

SAMPLE TULIP
Running
of the event:
At the start of the Rally the navigator is
handed over a ROUTE CHART (TULIP) alongwith
a SPEED CHART. The navigator then instructs the Driver to follow the route as
given in the Tulip. Routes are always given in KM (Kilometer) format with two
decimal digits as shown above.
o 0.00 km. -
START POINT
o 0.06 km
- TAKE RIGHT FROM ‘Y ‘ FORK
o 0.36 km
- GO STRAIGHT ROAD CONNECTS FROM RIGHT
The Driver / Navigator checks
the ODOMETER and follows instruction of the navigator. The Navigator will also
call out the average speed that needs to be maintained by the vehicle and it
becomes the responsibility of the Driver to adhere to such speed. If the Driver
fails to adhere to such speeds they may suddenly find the rope of the TC (TIME
CONTROL) visible in the route as TC’s
are undisclosed to the competitors. The TC Marshall will note down the Hitting
time of the car on his own sheet, which one member of the Crew- i.e. Any member
of the competing vehicle has to sign and the TC MARSHALL will also write down
the HITTING TIME in the Time Control Card (Time Control Card will be provided
at the start of the Rally).
- If
the Driver did not follow the average speed as called out by the navigator,
then he might have either hit the rope late or hit the early.
- From
the start of the event till the end of the route there might be numerous
Time Controls and all the Hitting Time will be recorded in the TCB
- Usually,
penalties of hitting early are more than hitting late. The vehicle with
the least penalties is adjudged WINNER.
Needless to mention that, vehicles not following
the correct route earns more penalties.
A vehicle may stop anywhere in the route but
NOT AT ALL at the sight of a TC MARSHALL. This means that as soon as you get to
see a TC you cannot STOP at all. Your car’s wheels must be moving (the vehicle may
crawl but CANNOT stop). If the Marshall sees you STOPPING or ZIGZAGGING OR
REVERSING then you are given Penalties.
After you hit a TC your hitting time is
recorded in the TCB. Please ascertain the OD (Official Distance) of the TC by
estimation or from the odometer (OD is not disclosed by the Marshall). Remember
to start calculating for the next sector (sector is from one TC to another TC)
from YOUR ACTUAL HITTING TIME of
the last TC.
Calculation
Tips for Navigation :
TIME = DISTANCE ¸ SPEED
Example :
To ascertain time to travel 9 km at an
average speed of 27 :-
Time =
9 ¸ 27
= 0.333333333 ® 0 Hrs.
= 0.333333333 x 60
=19.99999998 ® 19 Min.
= 0.99999998 x 60
=59.99999988 ® 59 Sec.
Therefore, to travel 9 km at an average speed
of 27 time required will be 00:19:59.
Motocross
Motocross is a form of motorcycle racing held on enclosed off road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. Motocross is a physically demanding sport held in all weather conditions. Modern motocross involves a multitude of styles, and types of racing, exhibitions and vehicles. The rugged terrain used for matches is what influences the design of the bikes and distinguishes them from other types of motorcycles. Motocross is usually held on man-made tracks, at large arenas or football stadiums or race tracks made from dirt and pavement.
Gymkhana
The events are usually held at closed courses such as parking lots, small circuits, big ground, stadium or other paved lots. The layout of the course is designed by the organizer and is different for each event.
Due to the tight course layout of gymkhana, smaller / lighter vehicles often have an advantage over larger ones. However, courses may include long straight ways in addition to tight turns, so various sizes and styles of machine are potential contenders.
Motorcycle gymkhana requires technique, ability, knowledge, and motorbike experience. This means riders must not only know techniques of acceleration, braking, reversing but also know tuning the machine to maximize performance. In addition, an analytical mind to assess the course for the most efficient racing lines is essential.
Drag racing
Drag racing is a competition in which prepared automobiles or motorcycles compete two at a time to be the first to cross a set finish line. From a standing START, in a straight line, over a measured distance, most commonly a ¼-mile (402.3-metre / 1,320 ft) on a straight track.
Each driver lines up at the starting line up. Usually Races are started electronically with separate lights for each driver / lane.
Below the staging lights are three large amber lights, a green light, and a red light. When both drivers are staged, the tree is activated to start the race, which causes the three large amber lights to illuminate, followed by the green light. There are two standard light sequences: either the three amber lights flash simultaneously, followed 0.4 seconds later by the green light (a Pro tree), or the ambers light in sequence from top to bottom, 0.5 seconds apart, followed 0.5 seconds later by the green light (a Sportsman tree, or full tree). If the front tires leaves from a stage beam (stage and pre-stage lights both turned off) before the green light illuminates, the red light for that driver's lane illuminates instead, indicating disqualification (unless a more serious violation occurs). Once a driver commits a red-light foul (also known as red lighting), the other driver can also commit a foul start by leaving the line too early but still win, having left later. Should both drivers leave after the green light illuminates, the one leaving first is said to have a holeshot advantage.
The winner is the first vehicle to cross the finish line (and therefore the driver with the lowest total reaction time and elapsed time).
Several measurements are taken for each race: reaction time, elapsed time, and speed. Reaction time is the period from the green light illuminating to the vehicle leaving the starting line. Elapsed time is the period from the vehicle leaving the starting line to crossing the finish line. Speed is measured through a speed trap covering the final 66 feet (20 m) to the finish line, indicating the approximate maximum speed of the vehicle during the run.
In the standard racing format, the losing car and driver are removed from the contest, while the winner goes on to race other winners, until only one is left.
