1.0 INTRODUCTIONThe very first aircraft has a little or no flying instrument. With that, it is very difficult for

the pilot. Flying in bad weather is very risky. Aircraft become one of the main transportation

when an accurate flight instrument facilitates pilot from necessity of maintaining visual contactwith the ground. Flight instruments are important to conducting safe flight operations and thepilot need to have a basic understanding of their operation. The basic flight instruments required

for operation under visual flight rules (VFR) are airspeed indicator (ASI), altimeter, and

magnetic direction indicator.

In addition to these, operation under instrument flight rules (IFR) requires a gyroscopic

rate-of-turn indicator, slip-skid indicator, sensitive altimeter adjustable for barometric pressure,

clock displaying hours, minutes, and seconds with a sweep-second pointer or digital

presentation, gyroscopic pitch-and-bank indicator (artificial horizon), and gyroscopic direction

indicator (directional gyro or equivalent).

2.0 OBJECTIVE

To ensure pilot can take off and land safely.

To enable the aircraft fly through the bad weather conditions and during night.

To ensure safety and reliable operation.

To give the early warning about any failure of aircrafts system/part so that the pilotcould take the immediate action.

3.0 PURPOSE

Why do pilot need basic flying instrument? Pilot need basic flying instrument to help

them overcome their limitation while flying. If theres no flying instrument, pilot have to faced

many problem while flying. Let take Charles Lindbergs journey as an example. He flies alone

over Atlantic Ocean successfully and takes about 33 hours to complete his journey. Lindberg

faced a few challenges such as bad weather, cant sleep during flight,no radio and no proper

communication and no navigator instruments and lastly, theres no proper water survival gears.Hes using see and avoid flying concept.

Technology nowadays has changed everything. With the help of the flying instrument, it is

easier for the pilot to fly. Pilot can flyfor a long time and distant miles away. One of the

instruments that help the pilot isautopilot. Autopilot is a Computer device thatcan fly an airplaneon its own. However, pilot is always present to monitor and check in whether the flight is going

according to plan or not.

4.0 EMERGENCE OF FLIGHT INSTRUMENT

On September 24, 1929, First flying blindperformed by Jimmy Doolittles.Flying Blind means fly by the aid of Flight Instrument only, without a view outside the

cockpit. Examples of basic flight instrument are:

4.1 Visual radio direction finder Using vibration system to direct the aircraft. The closer the plane is to the beacon, the

more intense the vibration.

4.2 Artificial horizon (Attitude Indicator) Showed the orientation of the flying aircraft in relation to the ground (show how the

wings were tilted, show whether aircraft nose up/down /level.

4.3 Barometric altimeter

Showed how far the aircraft above the ground. They will sensitively record the time andtherefore the distance from the aircraft to the ground.

5.0 WHAT IS INSTRUMENT FLIGHT RULES (IFR)

Instrument flight rules permit an aircraft to operate in instrument meteorological

conditions (IMC), which have much lower weather minimums than Visual Flight Rules (VFR).

Procedures and training are significantly more complex as a pilot must demonstrate competency

in conducting an entire cross-country flight in IMC conditions, while controlling the aircraftsolely by reference to instruments.

As compared toVFR flight, instrument pilots must meticulously evaluate weather, create a

very detailed flight plan based around specific instrument departure, en route, and arrivalprocedures, and dispatch the flight. Once airborne, the IFR pilot is then challenged to fly the

aircraft in the same air traffic control (ATC) environment and weather systems that two-crew jet

aircraft are using at the same time.

Rules of the road for flights permitted to penetrate clouds and low visibility conditions byreference to cockpit. Aircraft must be equipped and pilots qualified and current for IFR flight.Flight plans and ATC clearances are required. Flights are monitored and traffic separated by AirTraffic Control, usually by radar. Instrument Flight Rule (IFR) training combined with thenecessary instrumentation and the support of Air Traffic Control allows continued flight

operations in reduced or no visibility situations. All major airline pilots are IFR trained. IFRpilots are further trained to use on- board instrumentation to fly, and must communicate with AirTraffic Control, when operating above 18,000 feet. Instead of using only visuals, ATC cansupport them in navigation through bad weather and in separation from other aircraft and terrain .

6.0 BASIC FLIGHT INSTRUMENT

If an airplane could be flown by concentrating on only one instrument, flight on the

gauges would be easy. Normally, constant reference must be made to six basic flight instruments

as well as the navigation and engine instruments. This is accomplished through the pilot'sinstrument scan and the instrument pilot's most basic skill.

List of basic flying instrument:

6.1 Altimeter

An altimeter is simply a barometer calibrated in feet instead inches of mercury. With an

increase in altitude, since there is now less air above the airplane, the pressure is less. The

altimeter measures this reduced atmospheric pressure and displays it as the aircraft's altitude.Tocompensate for barometric pressure changes, the altimeter is frequently calibrated by the pilot by

setting the current barometric pressure in the altimeter setting window using a small knob.

6.2 Air Speed Indicator

The airspeed indicator is one of the oldest and most important of the flight instruments. Itmeasures the aircraft's speed through the air by measuring the dynamic pressure of the airstream

rushing against the moving airplane.During cruise, the aircraft may be flown within a fairlybroad speed range depending on whether fuel economy, range or flight time is the primary

objective. However, in no case can the pilot allow the aircraft to slow to stall speed - at which

point the wings can no longer sustain the aircraft - or accelerate to "red line," above whichstructural failure may result.

6.3 Vertical Speed Indicator

The vertical speed indicator, or VSI, measures the aircraft's rate of climb or descent asmeasured by the change in the surrounding atmospheric pressure, because of the instrument's

inherent delay or "lag," accurate climb or descent information is not available for several

seconds. For this reason, the VSI is useful only as a back-up instrument in most flight

maneuvers.

6.4 Attitude Indicator

In the middle of the top row of the panel is the attitude indicator, or artificial horizon, the

central element of the pilot's instrument scan. In instrument conditions, the attitude indicatorreplaces the natural horizon, showing the relationship of the nose and wings to the horizontal

plane. The attitude indicator is the only instrument that gives direct information about an

aircraft's attitude. Each movement of the aircraft's controls is therefore made with reference tothis instrument.

6.5 Heading Indicator

The heading indicator, or directional gyro, uses an internal gyroscope whose stability

provides accurate directional information once it is set to the correct heading. The gyro-stabilized

heading indicator is required because of the errors that occur in the magnetic compass duringturns, speed changes and even in turbulent air, because of drift errors, the instrument should be

checked against the magnetic compass during straight and level flight at least once every 15

minutes. Like the altimeter, a set knob is provided for corrections.

6.6 Turn Indicator

This electrically-driven instrument not only serves as a back-up to the attitude indicatorin the event of its failure, but also measures the rate and quality of a turn.In instrument flight

turns are typically made at a rate of three degrees per second or less; steeper turns are considered

dangerous. The quality of the turn is measured by the ball in the curved glass tube at the bottomof the instrument. A quality, or coordinated, turn balances centrifugal and gravitational forces

keeping the ball centered.

7.0 CONCLUSION

Basic flying instrument is very important to all pilots because without it flying will bevery difficult. They have to face lot of problem and they have to overcome their limitation while

flying. With the help of this modern technology, flying will be easier to all pilots.
