What is the difference between ifr and imc

This is typically done when flying through clouds, as well as general bad weather. Pilots are sometimes trained to fly in such conditions to teach them to rely on instrument indications. Instruments such as the attitude indicator and flight management systems can aid the pilot with flying without visual reference.

This is how most pilots begin their flying careers. The private pilot course teaches them to fly visually and to operate in VMC safely. To fly in IMC, they must possess an instrument rating, and be in an instrument-approved aircraft. The instrument rating is usually the second course a pilot takes, especially if they are pursuing a professional career path.

Limits are placed on VFR flights. They must maintain enough flight visibility that they can see the horizon and operate safely using visual references. VFR pilots are required to stay a safe distance from clouds since there could be an unseen IFR aircraft operating within. Since IMC is defined as weather that is below visual minimums, the only way to explain it precisely is to determine what the VFR minimums are in a given airspace.

Many controlled airspaces set the minimum VFR flight visibility to be three statute miles, and pilots must maintain feet below, feet above, and feet horizontal separation from clouds. The actual rules vary from one type of airspace to another, and beginning pilots learn the specifics of everywhere they will operate. In some places, like busy Class B airspace, pilots are allowed to get closer to clouds since all aircraft are receiving radar separation.

In other areas, like above 10, feet MSL , pilots must maintain greater visibility five miles and farther from clouds since, at this altitude, aircraft move much faster.

More warning and reaction time is required for see-and-avoid collision avoidance to work. Before a pilot can determine if they can operate as a VFR flight, they need to research what sorts of weather they can expect along their route of flight.

Aviation weather charts clearly show where instrument conditions are likely to happen since this is one of the most basic weather problems that pilots encounter. Somewhat unrelated to the operation of the aircraft, weather reports and charts have their own set of definitions of what constitutes VFR and IFR conditions. They even add more categories that do not exist in the regulations but are helpful when analyzing the weather along your route.

They do not necessarily mean that a pilot would be able to operate in VFR conditions while meeting all of the other regulatory requirements. If the pilot has managed to achieve straight, stable flight, do not make any control movement unless the AI shows that it is necessary, and even then make only small control inputs. Other receptors found throughout the body, known as somatosensory receptors commonly referred to giving feeling and G forces located all over the skin, bones, joints, skeletal muscles, internal organs and the parts of the cardiovascular system, will also be providing information to the brain.

This information can be in conflict with the visual and vestibular senses. These false or conflicting sensations can result in the pilot experiencing spatial disorientation even when in VMC.

Particularly during flight in poor visibility or in cloud all this can be catastrophic. This name is self explanatory. Having established stable straight and level flight, the next step is to consider ice protection.

In most cases, an inadvertent entry into IMC will be best resolved by a degree turn to fly back into the VFR conditions behind. This manoeuvre needs to be planned before attempting to execute the turn. Firstly, the direction of turn should be considered taking into account factors such as terrain on each side of the flight path.

For example, if before entry into IMC the pilot was aware of terrain to the left of track then a turn to the right might be the best plan. Before entering the turn, the pilot must decide on a target heading to roll out on.

Alternatively, if the stopwatch is started as the roll into the turn is initiated, a heading change of approximately degrees will be achieved in 1 minute. Whichever technique is used, it must not distract the pilot from keeping their attention on the AI throughout.

A bank angle of not more than 15 degrees will be sufficient. Controlling the bank angle is important. Keeping the bank angle low will mean that no additional back pressure will be required to maintain an effectively level turn. In addition, this will guard against the possibility of entering a spiral dive.

When entering and whilst maintaining the turn, the pilot should concentrate primarily on the attitude indicator. The DI should be checked occasionally to monitor the progress onto the desired heading but otherwise the concentration needs to be on the AI.

The pilot should anticipate reaching the desired heading then concentrate solely on rolling the aircraft by reference to the attitude indicator to re-establish straight and level flight. This should be maintained until the aircraft returns to VFR conditions. A period of time will have elapsed before the pilot recognised that entry in IMC had occurred, further time will have been utilised establishing straight and level flight and yet more time taken to plan the escape turn.

Therefore, once straight and level on the planned heading to exit, it may take a few minutes to get back to VFR conditions. If the degree turn fails to achieve a return to VMC then the pilot will need to accept that he will have to continue to manoeuvre the aircraft by sole reference to instruments.
