The critical angle of attack at which a given aircraft stalls is dependent on the?
design of the wing
Each aircraft has a particular angle of attack where the airflow separates from the upper surface of the wing and the stall occurs. This critical angle of attack varies from 16° to 20° depending on the aircraft's design. But each aircraft has only one specific angle of attack where the stall occurs.
If the airspeed increases and decreases during longitudinal phugoid oscillations, the aircraft?
is maintaining a nearly constant angle of attack
When the airspeed increases and decreases as an aircraft experiences phugoid oscillations (long-period longitudinal oscillations), the aircraft is demonstrating positive static stability and is maintaining a nearly constant angle of attack.
(Refer to Figure 23.) Which is a fowler flap?
Flap 4 is a Fowler flap. A Fowler flap moves out of the trailing edge of the wing on tracks and increases both the wing area and the amount of camber.
(Refer to Figure 21.) Which aircraft has the lowest aspect ratio?
Aspect ratio is the ratio of the wing span to the mean (average) wing chord.
Aircraft 8 has an aspect ratio of 9 (36 ÷ 4).
Aircraft 10 has an aspect ratio of 12.7 (57÷ 4.5).
Aircraft 12 has an aspect ratio of 25 (75÷ 3).
Which type of flap creates the least change in pitching moment?
The split flap produces the least change in the pitching moments of a wing when it is lowered.
It is possible to fly an aircraft just clear of the ground at a slightly slower airspeed than that required to sustain level flight at higher altitudes. This is the result of?
interference of the ground surface with the airflow patterns about the aircraft in flight
An aircraft can fly in ground effect at a slower airspeed than it can outside of ground effect because of the increased aerodynamic efficiency. Ground effect is due to the interference of the ground (or water) surface with the patterns of airflow about an airplane in flight. While the aircraft is in ground effect, the wing-tip vortices are altered, and the decrease in their effect changes the spanwise lift distribution, allowing an increase in lift with no increase in the angle of attack.
Consider the following statements about mountain waves:
1. Mountain waves always develop in a series on the upwind (windward) side of mountain ridges.
2. In a mountain wave, the air dips sharply downward immediately to the lee side of a ridge, before rising and falling in a wave motion for a considerable distance downstream.
3. If the air is humid and the wave is of large amplitude, lenticular (lens-shaped) clouds mark the wave's crest.
4. In a typical wave, the greatest amplitude is seldom more than 1,000 feet above the ridge crest elevation. From the statements above, select those which are true.
2 and 3
With regard to mountain waves, statements 2 and 3 are both true. In a mountain wave, the air dips sharply downward immediately to the lee side of a ridge, before rising and falling in a wave motion for a considerable distance downstream. If the air is humid and the wave is large in amplitude, lenticular (lens-shaped) clouds mark the wave's crest.
How will an area of thunderstorm activity that may grow to severe intensity be indicated on the Severe Weather Outlook Chart?
APCHG within any area
On a Severe Weather Outlook Chart, an area labeled "APCHG" indicates that probable general thunderstorm activity may approach severe intensity.
Regarding Convective Outlook Charts, when well-organized severe thunderstorms are expected, but in small numbers and/or low coverage, the risk is referred to as?
Slight (SLGT) risk implies well-organized severe thunderstorms are expected but in small numbers and/or low coverage.
When converting from true heading to true course, a pilot should?
subtract right wind correction angle
When converting from a true heading to a true course, subtract a right wind correction angle or add a left wind correction angle.
After 150 miles are flown from the departure point, the aircraft's position is located 8 miles off course. If 160 miles remain to be flown, what approximate total correction should be made to converge on the destination?
1. Find the change in heading needed to parallel the original course with the formula. Degrees to parallel = miles off course x 60 ÷ miles flown8 x 60 ÷ 150 = 3.2°2. Find the change in heading needed to converge on the destination in 160 miles with the formula. Degrees to converge = miles off course x 60 ÷ miles to fly8 x 60 ÷ 160 = 3°3. Add these two corrections to find the total correction required to converge on the destination. 3.2 + 3 = 6.2°
While maintaining a magnetic heading of 060° and a true airspeed of 130 knots, the 150° radial of a VOR is crossed at 1137 and the 140° radial at 1145. The approximate time and distance to the station would be?
48 minutes and 104 NM
Time to Station = 60 x minutes between bearing changes ÷ degree of bearing change
60 x 8 ÷ 10 = 48 minutes
Distance to station = TAS x minutes between bearing changes ÷ degree of bearing change
130 x 8 ÷ 10 = 104 nautical miles
Regulations stipulate that, at an airport located within Class E airspace and at which ground visibility is not reported, takeoffs and landings of airplanes under special VFR are?
authorized if the flight visibility is at least 1 SM
No person may operate an aircraft within the lateral boundaries of Class B, C, D, or E airspace designated for an airport under the Special VFR weather minimums where ground visibility is not reported, unless flight visibility during landing and takeoff is at least 1 statute mile.
What is V(2) speed?
Takeoff safety speed
V(2) means takeoff safety speed
(Refer to Figure 52.) During practice of lazy eights, the most probable cause of the uncoordinated situation at the completion of 90° of turn (indicated by the turn-and-slip indicator shown in '1') is the?
use of too much right rudder pressure
A slip is shown in the turn-and-slip indicator '1,' which is the result of too much right rudder pressure.
(Refer to Figure 49.) Which position will require the steepest bank?
The closer the aircraft is to a direct downwind heading where the ground speed is greatest, the steeper the angle of bank. This would be point 7.
(Refer to Figure 23.) Which is a slotted flap?
Flap 3 is a slotted flap. When the flap is lowered, a slot is formed between the leading edge of the flap and the flap well in the wing.
Fuel/air ratio is the ratio between the?
weight of fuel and weight of air entering the cylinder.
The fuel-air mixture ratio used in aircraft engines is the ratio of the weight of the fuel to the weight of the air in the mixture entering the cylinders.
What precautions should be taken with respect to aircraft oxygen systems?
Ensure that industrial oxygen has not been used to replenish the system.
When servicing an aircraft oxygen system, be sure that industrial oxygen is not used. Only oxygen marked 'Aviators Breathing Oxygen' which meets Federal Specification BB-O-925A, Grade A or equivalent may be used.
(Refer to Figure 35.) If 50-pound weights are located at points X, Y, and Z, how would point Z have to be shifted to balance the plank?
25 inches to the left
1. Find the moments left and right of the fulcrum, and set them equal to one another.
left = right50(50) + 50(25) = 50(Z)
3,750 = 50ZZ = 75 inches
2. The 50-pound weight must be 75 inches from the fulcrum to be in balance. It is currently located at 100 inches, therefore the weight should be shifted 25 inches to the left.
An aircraft is flying at a constant power setting and constant indicated altitude. If the outside air temperature (OAT) decreases, true airspeed will...
decrease, and true altitude will decrease.
True airspeed and true altitude are based on the existing outside air temperature, which affects the density of the air. While flying at a constant power setting and a constant indicated altitude, a decrease in OAT will cause the air to become more dense, and the true airspeed will decrease and the true altitude will be lower than indicated altitude.
On a cross-country flight, point X is crossed at 1015 and arrival at point Y is expected at 1025. Use the following information to determine the indicated airspeed required to reach point Y on schedule.
Distance between X and Y 27 NM
Forecast wind 240° at 30 kts
Pressure altitude 5,500 ft
Ambient temperature +05°C
True course 100°
The required indicated airspeed would be approximately
1. Find the ground speed that must be made between points A and B (Ground Speed on FLT menu):
Distance (Dist) 27 NM
Duration (Dur) 10 MIN
Ground Speed (GS) 162 KTS
2. Find the true airspeed (Wind Correction on FLT menu):
Ground Speed (GS) 162 KTS
True Course (TCrs) 100 degrees
Wind Speed (WSpd) 30 KTS
Wind Direction (WDir) 240 degrees
True Airspeed (TAS) 140.3 KTS
True Heading (THdg) 108 degrees
3. Find the required indicated airspeed (or calibrated airspeed) (Airspeed on FLT menu):
True Airspeed (TAS) 140.3

(Refer to Figure 46.) The area south of GNOSS (Area 4) is a?
The crossed-out hollow circle north of NOVATO depicts an abandoned airport.
A private pilot with an airplane single-engine land rating may act as pilot in command of an airplane towing a glider if, within the preceding 24 months, this pilot has made?
three flights as pilot in command of a glider towed by an aircraft.
No pilot may act as pilot-in-command of an aircraft towing a glider unless he/she meets the following requirements: Within the preceding 24 months he/she has made at least 3 flights as pilot-in-command of a glider towed by an aircraft.
What action should be taken if a glider and an airplane approach each other at the same altitude and on a head-on collision course?
Both should give way to the right.
When aircraft are approaching each other head-on, or nearly so, each pilot of each aircraft shall alter course to the right.
During the entry to a right turn, the nose of the aircraft swings slightly to the left before it swings along the horizon to the right. This is a?
slipping entry; more right rudder pressure should have been applied for the amount of aileron pressure being used.
Adverse yaw, caused by the induced drag from the down aileron, causes the nose of an aircraft to initially move in the direction opposite the desired direction of the turn. This is a slipping-turn entry, and more rudder pressure should have been applied for the amount of aileron pressure being used.
