Why is the propeller twisted?2020-10-30T09:21:45-04:00

#### Why is the propeller twisted?

The propeller blades are twisted to help the meet the air at almost the same angle of attack along their length which improves efficiency.

Why does stall speed increase in a turn?2021-01-25T09:20:33-05:00

#### Why does stall speed increase in a turn?

Stalling speed increases in a turn because of the increase in load factor. The airplane isn’t actually heavier. It is fake weight, but the airplane reacts to it. With more weight, fake or not, the angle of attack needs to be increased to maintain lift. Even in level flight a heavier identical airplane flying at the same speed (with increased power) will need to fly at a greater angle of attack to maintain altitude. The greater the angle of attack the closer your are to the critical angle of attack, or stalling speed. A wing on most general aviation airplanes stalls between 16Â° and 18Â°. An identical heavier airplane, loaded with fake weight or actual weight, will reach the critical angle of attack at a greater airspeed, thus entering a stall.

Why do we lean the mixture as we climb?2020-10-30T07:45:54-04:00

#### Why do we lean the mixture as we climb?

We lean the mixture as we climb because of the decrease in air density. We are trying to keep the ratio of fuel to air by mass constant, not by volume. The volume remains the same. The combustion chamber does not change in size. However, the decreasing air density, because of decreasing pressure, continues to decrease the number of air molecules that enter the combustion chamber. Say our proper fuel/air ratio is 1:1 at sea level. If we climbed to 10,000 feet and did not lean the mixture we might end up with a fuel/air ratio of 2:1.

What is the Standard Pressure Region?2021-01-23T22:27:34-05:00

#### What is the Standard Pressure Region?

The standard pressure region is airspace that includes the Northern Domestic Airspace and all airspace above 18,000ft within the Southern Domestic Airspace. When flying in the Standard Pressure Region, your altimeter is set to 29.92 in Hg and all altitudes are expressed as “flight levels.”

For example:
FL210 = 21,000 ft
FL90 = 9,000ft

To maintain vertical separation between aircraft flying high in the Altimeter Setting Region of the Southern Domestic Airspace and the Standard Pressure Region, there are lowest useable flight levels for lower than normal pressure measurements.
If the altimeter setting is 29.92 in Hg or higher, the lowest usable flight level is FL180
For 28.92 to 29.91 in Hg, it’s FL190.
And for 2792-28.91 in Hg, it’s FL200.

What is the speed limit of an aircraft below 3,000ft within 10nm radius of a controlled airport?2021-01-23T20:35:51-05:00

#### What is the speed limit of an aircraft below 3,000ft within 10nm radius of a controlled airport?

What is the Rule of Thumb for converting from IAS to TAS?2020-10-21T12:08:26-04:00

#### What is the Rule of Thumb for converting from IAS to TAS?

When converting from IAS to TAS the rule of thumb is is that TAS increases by 1.5% over IAS for every thousand feet up to 20,000 feet.

For example, if you are flying at 4000 feet and your IAS is 100 KTs your TAS will be roughly 106 KT TAS.

100 * 0.015 = 1.5
1.5 * 4 = 6
100 + 6 = 106 KT TAS

What is the rule of thumb for calculating maximum x-wind speed for a given plane?2020-10-29T15:40:46-04:00

#### What is the rule of thumb for calculating maximum x-wind speed for a given plane?

The rule of thumb for calculating maximum safe crosswind is to take the clean stall speed of the airplane and multiply it by 0.2.

Ex: 50KT stall speed would mean the airplane should be safe in 10KTs of direct x-wind.

What is the rule of thumb for calculating DENSITY ALTITUDE?2020-10-23T08:26:04-04:00

#### What is the rule of thumb for calculating DENSITY ALTITUDE?

The rule of thumb for calculating density altitude is to add 120 feet to the pressure altitude for each degree above standard temperature.

For example. If you pressure altitude was 700 feet and the temp was 28 degrees Celsius you would add 1560 feet to your pressure altitude giving you an approximate density altitude of 2260 feet.

Remember high temperatures, high humidity, high altitudes, and low pressure all contribute to raising the density altitude.

What is the rule of thumb for calculating a rate one turn angle of bank?2020-10-29T11:40:28-04:00

#### What is the rule of thumb for calculating a rate one turn angle of bank?

The rule of thumb is to take your TAS in KT, divide by 10 and add 7.

AoB = TAS / 10 + 7

What is the required altimeter accuracy for IFR flight?2021-01-23T22:55:29-05:00

#### What is the required altimeter accuracy for IFR flight?

If there is an altimeter error of more than 50 feet while on the ground, you have a problem.
To check the accuracy, apply the present altimeter setting to the altimeter and compare the altitude indicated with the runway or aerodrome elevation. The altimeter should be within 50 feet +/- of the elevation of the runway. If the deviation is more, have the instrument checked by maintenance.

What is the Northern Control Area?2021-01-23T20:29:44-05:00

#### What is the Northern Control Area?

It is located within the Northern Domestic Airspace. It is controlled airspace extending upwards from FL230 to FL600.

What is the difference between Service Ceiling and Absolute Ceiling?2020-10-29T08:25:10-04:00

#### What is the difference between Service Ceiling and Absolute Ceiling?

Service Ceiling is the height at which the maximum rate of climb reduces to 100 fpm.

Absolute Ceiling is the height at which the rate of climb is reduced to zero (0).

What is the difference between Detonation and Pre-ignition?2020-10-29T11:19:45-04:00

#### What is the difference between Detonation and Pre-ignition?

Detonation is when the fuel/air mixture burns all at once in the cylinder as opposed to slowly starting from the spark plug. It can occur when the engine is running too hot, when running low octane fuel, or when running too high a manifold pressure for the RPM. The symptom are engine roughness, vibration, or loss of power.

Pre-ingnition is when the fuel/air mixture is igniting before the spark plug sparks. This usually happens when small accumulations of lead or carbon build up on the piston head, or commonly, on the spark plug. These accumulations heat up and ignite the fuel/air mixture out of sequence, usually during the compression stroke. The symptoms are lack of power and engine roughness.

What is the difference between a Skid and a Slip?2020-10-30T08:27:00-04:00

#### What is the difference between a Skid and a Slip?

In a skid the tail is outside of the turn. In a slip the tail is inside of the turn. If the tail is positioned inside or outside of a turn it means you are presenting some part of the side of the fuselage to the relative airflow and thus are creating more drag.

What is the CHORD of a wing?2020-10-28T09:39:56-04:00

#### What is the CHORD of a wing?

Chord is an imaginary straight line drawn from the leading edge to the trailing edge.

What is the CAMBER LINE and how does it relate to CAMBER?2020-10-28T09:39:32-04:00

#### What is the CAMBER LINE and how does it relate to CAMBER?

The camber line is an imaginary line that runs through the centre of the wing, from leading edge to trailing edge. It remains equal distance from the top of the wing to the bottom of the wing.

Camber is the measure of the curvature of a wing. In simple terms, it is a distance measurement from the chord line to the camber line. Camber is measured as a percentage of the chord. If you had a chord line that was 200cm long and the greatest measured distance from the chord line to the camber line was 30cm you would have a 15% camber.

A greater camber would equate to more lift at lower speeds, but consequently more drag at higher speeds. Think about how the application of flaps changes the flight characteristics of your airplane. With flaps you create more lift at lower speeds (your stall speed decreases), however you increase the amount of induced drag.

What is the boundary layer?2020-10-29T08:44:43-04:00

#### What is the boundary layer?

The boundary layer is the airflow nearest the skin of the wing.

What is the Arctic Control Area?2021-01-23T20:28:38-05:00

#### What is the Arctic Control Area?

The most northern section of the Northern Domestic Airspace. It is controlled airspace extending upwards from FL270 to FL600.

What is the Angle of Incidence?2020-10-28T10:59:39-04:00

#### What is the Angle of Incidence?

The Angle of Incidence is the angle between the chord line of the wing and the longitudinal axis of the plane. Not to be confused with the angle of attack. The angle of incidence remains static while the angle of attack is dynamic.

What is required for VFR flight into Class ‘C’ airspace?2020-08-12T15:29:07-04:00

#### What is required for VFR flight into Class ‘C’ airspace?

The following is required:

• a mode ‘C’ transponder
• a two-way radio or prior approval
• an ATC clearance
• continuous listening watch on frequency assigned by ATC
What is Dihedral?2020-10-30T07:34:12-04:00

#### What is Dihedral?

Dihedral is a type of wing design in which the wings appear to bend upwards from the fuselage to the wing tip. This is not to be confused with washout. Although they both attempt to provide greater stability about the longitudinal axis, aka roll stability.

Dead Reckoning is the act of navigating based only on calculations of distance, track, true airspeed, and forecast wind information. You use these calculations to find your en route time, your heading and your ground speed.

What is Aspect Ratio?2020-10-28T10:56:05-04:00

#### What is Aspect Ratio?

Aspect ratio is SPAN divided by AVERAGE CHORD.

For example:
Wing span = 40.5 feet
Avg. chord = 6.3 feet
Aspect Ratio = 40.5 / 6.3
Aspect Ratio = 6.42

Keep in mind two airplanes can have very different wing span length but still have the same total wing area. An aircraft with a high aspect ratio generally produces less induced drag than low aspect ratio aircraft. Example: a glider (high aspect ratio) and a Piper Warrior (low aspect ratio).

High aspect ratio wings are more expensive to produce and are heavier.

What is Angle of Attack?2020-10-28T09:49:07-04:00

#### What is Angle of Attack?

Angle of Attack is the angle between the chord line and the relative airflow (sometimes called relative wind). All wings will stall when they reach the critical angle of attack which is between 16-18 degrees.

Angle of attack is greatest at low air speeds in relation to your plane. 40KTs could be slow in a Cessna 152 while 80KTs might be slow in a light twin engine plane such as a Piper Seneca. Even though the speeds are different in each plane it is possible that at that speed they would both be flying at the same (high) angle of attack.

What is an isogonal?2020-11-01T13:50:49-05:00

#### What is an isogonal?

An isogonal is a line on a map/chart joint point of equal magnetic variation.

What is a VORTAC? Does it supply DME info?2020-10-23T08:40:44-04:00

#### What is a VORTAC? Does it supply DME info?

A VORTAC is a VOR (VHF omnidirectional range) combined with a TACAN (tactical air navigation system). VORs are used in civil aviation and TACANs are used by the military. VORTACs provide DME (distance measuring equipment) that can be used by both civil and military equipment. However, you must have DME in your airplane to make use of it.

What is a trim tab?2020-12-14T07:59:00-05:00

#### What is a trim tab?

Trim tabs are used to balance control forces. If there was not a trim tab the pilot would constantly need to hold the control column in place to maintain the desired attitude.

What is a low-level airway?2021-01-23T20:55:48-05:00

#### What is a low-level airway?

They are controlled airspace classified as Class B or Class E. Class B extends from 12,501ft or the MEA (whichever is highest), up to 17,999ft ASL. Class E extends from 2,200ft AGL up to the bottom of the Class B airspace.Â  The lateral dimensions of the airways depend on what navaids they are based off of. They can be VORs, NDBs, or a combination of the two.

An airway based off of two VORs will have a splay angle of 4Â° on either side of the center line, which will intersect with the basic width boundary of the airway 50.8nm from the navaids at either end of the airway.

One VOR and one NDB will have a splay angle of 4.34Â° on either side of the center line, which will intersect with the basic width boundary of the airway 49.66nm from the navaids at either end of the airway.Â  The same goes for and airway based off two NDBs.

What is a low-level air route?2021-01-23T20:15:11-05:00

#### What is a low-level air route?

It is uncontrolled airspace that extends from the surface of the earth up to, but not including, 18,000ft.

What is a high performance airplane?2020-11-01T11:36:49-05:00

#### What is a high performance airplane?

What is a flight crew members maximum flight duty time?2020-08-12T16:57:00-04:00

#### What is a flight crew members maximum flight duty time?

A flight crew member may not be on duty for more than 14 consecutive hours in any 24 consecutive hours.

What is a cause of the 15Â° drift per hour in heading indicators?2021-01-23T21:59:45-05:00

#### What is a cause of the 15Â° drift per hour in heading indicators?

While the gyroscopic axis remains fixed in space, the earth continues to rotate, causing the approximate 15Â° drift per hour. This is why we need to adjust the heading indicator to match the compass every 15-20 minutes so we can stay on track.

What is “washout”?2020-10-29T16:43:37-04:00

#### What is “washout”?

Washout is a type of wing design where the angle of incidence reduces from the wing root to the wing tip. The angle of incidence is the angle between the longitudinal axis of the airplane and the chord line of the wing. Washout is like a warp in the wing. Washout makes it so the wing root reaches a higher angle of attack before the wing tip. This means the wing root will stall before the wing tip and thus creates more stability about the longitudinal axis; otherwise known as roll stability.

What happens when a wing stalls?2020-10-29T09:02:47-04:00

#### What happens when a wing stalls?

Most general aviation wings stall between 16Â° and 18Â°. This is known as the critical angle of attack. As you increase the angle of attack the centre of pressure (bottom of the wing) moves forward. As this happens the boundary layer is unable to follow the contour of the wing and begins to separate from the top of the wing starting at the trailing edge. As the angle of attack continues to increase the centre of pressure continues to move forward and as subsequently the boundary layer continues to separate from the top of the wing moving toward the leading edge. When the maximum lift coefficient is reached the stall occurs and the center of pressure rapidly moves backwards. This causes the nose to pitch down.

#### What factors affect turn radius?

True airspeed and angle of bank. The lower the true airspeed and the greater the angle of bank the tighter the turn. Don’t forget that your stall speed increases in a turn.

What effect will rain have on my landing approach?2020-10-27T11:16:30-04:00

#### What effect will rain have on my landing approach?

Rain will give you the illusion that you are closer to the runway than you actually are because of the magnification from the rain droplets on the windscreen.

What effect does weight have on the range of an airplane?2020-10-29T07:41:14-04:00

#### What effect does weight have on the range of an airplane?

Weight will reduce the range of your airplane. Added weight will require more lift. More lift means more induced drag. More drag means more power is necessary and consequently greater fuel consumption. In the same airplane loaded with more weight at the same power setting you will arrive at your destination later (given the same atmospheric conditions). In order to increase range it would be wise to load the airplane with the C of G more aft (but still within limits).

What effect does weight have on glide distance?2020-12-19T10:25:45-05:00

#### What effect does weight have on glide distance?

Weight has no effect on gliding distance provided the lift to drag ratios are the same. A lightly loaded plane will have greater glide endurance but will glide the same distance as a heavier plane in zero wind conditions.

What effect does temperature have on altimeter readings?2020-10-26T09:35:20-04:00

#### What effect does temperature have on altimeter readings?

In cold air the altimeter will over read. In warm air the altimeter will under read. Remember that standard temperature is 15 degrees Celsius.

From hot to cold, don’t be bold. When flying from an area of warm air to an area of cold air be careful as your altimeter will likely be over reading. Your altimeter will be telling you that you are at a higher altitude than you actually are.

What does the term “No PT…” mean on an approach plate?2021-01-23T19:58:13-05:00

#### What does the term “No PT…” mean on an approach plate?

What does a standard hold, up to and including 14,000ft, involve?2021-01-23T20:12:16-05:00

#### What does a standard hold, up to and including 14,000ft, involve?

1 minute legs, rate 1 turns to the right with a maximum bank angle of 25Â°, and a maximum speed of 175kts in a propeller driven aircraft.

What are winglets?2020-10-30T08:53:43-04:00

#### What are winglets?

Winglets are 90Â° upward bends at the wing tip. They significantly reduce the amount of drag and loss of lift caused by wingtip vortices. This translates to improved cruising speeds, improved time/climb rates, and increase operating altitudes.

What are Vortex Generators?2020-10-29T16:53:11-04:00

#### What are Vortex Generators?

Vortex Generators are little tabs the stick up from the wing surface. Their function is to mix the lower velocity air of the boundary layer with the higher velocity air outside the boundary layer. This helps to recharge the boundary layer and delays separation of the boundary layer from the wing top.

As the angle of attack increases the boundary layer (of air) begins to separate from the wing top starting at the trail edge. As the the angle of attack continues to increase the boundary layer continues to separate moving toward the leading edge of the wing.

What are the weather requirements for an airport, with no authorized IAP, being used as an alternate?2021-01-24T21:40:50-05:00

#### What are the weather requirements for an airport, with no authorized IAP, being used as an alternate?

What are the types of Hypoxia?2020-10-27T10:50:16-04:00

#### What are the types of Hypoxia?

Histoxic Hypoxia results when organs are not able to absorb oxygen properly. Such as when under the influence of alcohol.

Hypoxic Hypoxia results when there is not enough oxygen in the air. Such as at high altitudes.

Anemic Hypoxia results when the blood cannot aborb oxygen and distribute it to different parts or the body. Such as during carbon monoxide poisoning.

Stagnant Hypoxia results when blood cannot move through the body freely. Such as during long periods of sitting.

What are the track error correction methods?2020-10-21T11:37:39-04:00

#### What are the track error correction methods?

Double track error correction: double your drift angle left or right depending on which side of track you have drifted and fly that heading to regain your track. This will only work if you are less than halfway to your destination.

Opening and closing angle method: use the 1:60 rule to find your opening and closing drift angles, and them together, and then correct your current heading left or right by the sum of the two angle to fly DIRECTLY to your destination.

Visual track error method: fly to a known landmark on your planned track and then alter your heading to correct for drift to fly along your track to your destination.

How do I calculate time, fuel, and distance to climb?2020-11-02T07:18:50-05:00

#### How do I calculate time, fuel, and distance to climb?

In order to calculate time to climb you need:

1. the vertical distance you are climbing (ex SL to 4000 feet = 4000 feet)
2. your climb rate (ex 500 feet per minute)

Example:
Time to climb = 4000/500
Time to climb = 8 minutes

In order to calculate fuel burnedÂ  you need:

1. Time to climb (8 mins)
2. Fuel flow (9 Gph)
3. The number 60

Example:
Fuel burned for climb = 8 * 9 / 60
Fuel burned for climb = 1.2 Gallons

To calculate distance traveled during your climb you will need:

1. Â Time to climb (8 mins)
2. Your ground speed (ex 70 kt)
3. The number 60

Example:
Distance traveled during climb = 8 * 70 / 60
