What wings does the Boeing 737-800 use?
What wings does the Boeing 737-800 use?
Swept back wings
What is BEM?
What is BEM?
Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.
What effect does a wet runway have on V1?
What effect does a wet runway have on V1?
V1 is lower when the runway is wet than when the runway is dry, because of the longer ASDR on a wet runway.
What are winglets and what is the advantage of winglets?
What are winglets and what is the advantage of winglets?
They are aerodynamically efficient surfaces located at the wing tips, designed to reduce induced drag and increase fuel efficiency.
They increase efficiency by reducing the size of the wingtip vortices, which are created by the difference between the pressure on the upper surface of the wing and that on the lower surface.
What weather is associated with windshear?
What weather is associated with windshear?
CAT
Frontal passage
Microburst
What uses the most battery power, to transmit or to receive?
What uses the most battery power, to transmit or to receive?
Transmitting uses more power.
What is the speed of sound at sea level according to ISA?
What is the speed of sound at sea level according to ISA?
662 kts
Local speed of sound = 39 x √(Temperature in Kelvin)
15°C in Kelvin is (15 + 273) = 288
So the local speed of sound = 39 x √288 = 662 kts
Being an excellent pilot, if I can fly at VMCA, do I need a V2 speed?
Being an excellent pilot, if I can fly at VMCA, do I need a V2 speed?
Yes, for safety you will need a V2 speed.
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.
Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.
What is the movement of the center of pressure during/approaching a stall?
What is the movement of the center of pressure during/approaching a stall?
Center of pressure moves forward when approaching a stall.
