How do you fly a back course approach?

Mar 24, 2018 · The "front course" is the LOC navigation used to fly a standard ILS or LOC approach. When flying standard approaches, the localizer is situated at the departure end of the runway you're landing on. When you're using LOC BC approach, your receiver references signals emitting from opposite side of the localizer antenna.

How do you steer an aircraft on the back course?

The localizer (LOC) provides lateral course guidance during an approach to landing; Instrumentation operates between 108 - 111.95 MHz on one of 40 channels that transmits from a ground node. The localizer's approach course, used with other functional parts (glide-slope, marker beacons, etc.), is called the front course

What is the back course of a runway called?

What frequency is the glide slope transmitter?

The UHF glide-slope transmitter, operating on one of the 40 ILS channels within the frequency range 329.15 MHz, to 335.00 MHz radiates its signals in the direction of the localizer front course

What is a glide path?

The term glide path means that portion of the glide-slope that intersects the localizer. CAUTION: False glide-slope signals may exist in the area of the localizer back course approach, which can cause the glide-slope flag alarm to disappear and present unreliable glide-slope information.

Why is there no transition training in GA?

The lack of transition training has been cited as a causal factor in many GA accidents. Accidents frequently result from pilots being unprepared for challenges presented by the new, or different, aircraft they are flying. Even when pilots are legally certificated to operate aircraft within a specific category and class, significant differences can exist among different types of aircraft within that category and class — thus necessitating the need for effective transition training.

Is it important to step down from an airplane?

Transitioning to another aircraft works both ways — stepping down is just as important as stepping up. It’s not just about learning how to fly a more complex airplane. It’s also about learning to transition from high performance aircraft to aircraft with lower performance and complexity, which can be equally challenging.

How to navigate to a particular destination?

To navigate to a particular destination, the first step is to determine exactly where you are right now. The same principle applies in ADM: to navigate to a safe outcome, you first need to understand the “given set of circumstances” you face.

Why do we take more effort in life?

Others (e.g., changing jobs) take more effort because they have significant and lasting implications.

Can humans avoid errors?

No matter how hard we try, it is simply not possible for human beings to avoid errors entirely, especially when complex systems are involved. By using a systematic approach to continuous ADM, however, and developing awareness of common types of human ADM error, we can seek to minimize mistakes.

What is a master switch?

The battery switch is often referred to as the master switch since it turns off or on virtually all electrical power by controlling the battery connection. Note how the electrical connections of the battery solenoid are protected from electrical shorts by rubber covers at the end of each wire. Figure 3.

How does an aircraft use power?

Many aircraft employ an external power circuit that provides a means of connecting electrical power from a ground source to the aircraft. External power is often used for starting the engine or maintenance activities on the aircraft. This type of system allows operation of various electrical systems without discharging the battery. The external power systems typically consists of an electrical plug located in a convenient area of the fuselage, an electrical solenoid used to connect external power to the bus, and the related wiring for the system. A common external power receptacle is shown in Figure 7.

Why do airplanes have a separate power distribution bus?

Since modern avionics equipment employs sensitive electronic circuits, it is often advantageous to disconnect all avionics from electrical power to protect their circuits. For example, the avionics bus is often depowered when the starter motor is activated. This helps to prevent any transient voltage spikes produced by the starter from entering the sensitive avionics. [Figure 11]

What is an aircraft battery?

The aircraft battery is used for emergency power and engine starting . Electrical power is typically distributed through one or more common points known as an electrical bus (or bus bar). Almost all electrical circuits must be protected from faults that can occur in the system.

How does a generator work?

Generator circuits are used to control electrical power between the aircraft generator and the distribution bus. Typically, these circuits are found on older aircraft that have not upgraded to an alternator. Generator circuits control power to the field winding and electrical power from the generator to the electrical bus. A generator master switch is used to turn on the generator typically by controlling field current. If the generator is spinning and current is sent to the field circuit, the generator produces electrical power. The power output of the generator is controlled through the generator control unit (or voltage regulator). A simplified generator control circuit is shown in Figure 4. As can be seen in Figure 4, the generator switch controls the power to the generator field (F terminal). The generator output current is supplied to the aircraft bus through the armature circuit (A terminal) of the generator.

What is AC supply?

AC Supply. Many modern light aircraft employ a low-power AC electrical system. Commonly, the AC system is used to power certain instruments and some lighting that operate only using AC. The electroluminescent panel has become a popular lighting system for aircraft instrument panels and requires AC.

How many amps does an airplane starter draw?

Since starting the engine requires several horsepower, the starter motor can often draw 100 or more amperes. For this reason, all starter motors are controlled through a solenoid. [Figure 9]

What is a switch in an airplane?

Switches. Switches are installed in the cockpit to open and close specific electrical circuits; thereby powering up or down the electronic equipment wired to that switch. Switches either close to complete a circuit or open to break a circuit. Figure 7: An example of toggle and rocker aircraft switches.

What is the electrical system of an aircraft?

The electrical system installed on an aircraft comprises of two electrical sources: a battery which is primarily used to operate the system when the engine is not running, and an alternator (or DC generator), which runs off the engine and is designed to provide a continuous supply of electricity to power ...

How does a fuse work?

A fuse is constructed by installing a small element of conductive material between two end caps. This material, or fusible link, is designed to melt when exposed to a current greater than or equal to the fuse design limit. This automatically breaks the circuit, protecting the equipment downstream of the fuse. Fuses are not reusable as the high current destroys the fusible link. It is important to carry a set of extra fuses when flying an aircraft designed with a fuse protection system so that the fuse can be replaced if it blows mid-flight. Similar to a circuit breaker, installing a fuse with a higher rating than specified will not adequately protect the equipment from a current surge. A blown fuse should always be replaced by one of the correct grading.

What is AC in an alternator?

A Direct Current (DC) system is used to power the electric components on an aircraft; an alternator produces an Alternating Current (AC) and so must be converted to DC via a rectifier before entering the busbar.

What happens if an alternator fails?

In the case of an in-flight alternator failure, the battery will continue to run the electrical components until the battery charge is depleted. In some aircraft a generator malfunction light will illuminate if the generator/alternator is no longer producing the electricity required to run the system.

What is the difference between a fuses and a circuit breaker?

The primary difference between the two is that circuit breakers can be re-set in situ, while fuses must be replaced once triggered.

How does a breaker work?

A circuit breaker is designed to trip at a set current draw and can be manually reset each time it does. A metallic element is built into the breaker that will expand and contract as a result of the temperature change associated with increased or decreased current flow. An increased current flow will cause the element to heat up and expand, and once the critical current is reached, this expansion is sufficient to force open a set of contacts in the breaker, causing the circuit to break.

What are the advantages of dual ignition?

The main advantages of the dual ignition system are: 1. Increased safety. In case one system fails, the engine may be operated on the other until a landing is safely made. Consequently, it is extremely important for each magneto to be checked for proper operation before takeoff.

What is the purpose of an ignition system?

ignition system. The function of the ignition system is to provide an electrical spark to ignite the fuel/air mixture in the cylinders. The ignition system of the engine is completely separate from the airplane's electrical system. The magneto type ignition system is used on most reciprocating aircraft engines.

What is magneto ignition?

The magneto type ignition system is used on most reciprocating aircraft engines. Magnetos are engine driven self-contained units supplying electrical current without using an external source of current. However, before they can produce current the magnetos must be actuated as the engine crankshaft is rotated by some other means.
