What can you tell about occluded fronts?
What can you tell about occluded fronts?
Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.
Occluded fronts usually form around mature low pressure areas.
What is Mcrit?
What is Mcrit?
Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
Does a jet have a critical engine? Why yes or no?
Does a jet have a critical engine? Why yes or no?
No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
Approach category speeds are defined by which formula?
Approach category speeds are defined by which formula?
This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.
The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.
What do the abbreviations TSRA and MIFG mean?
What do the abbreviations TSRA and MIFG mean?
TSRA: Thunderstorm with rain
- MIFG: Shallow fog
Do single engined planes have a VMCG?
Do single engined planes have a VMCG?
No, VMCG is defined as the minimum control speed on the ground, with one engine inoperative (critical engine on two engine airplanes), takeoff power on other engine(s), using aerodynamic controls only for directional control and thus only applicable to ME aircraft.
How does an aerofoil work?
How does an aerofoil work?
An aerofoil is a body shaped to produce an aerodynamic reaction (lift) perpendicular to its direction of motion, for a small resistance (drag) force in that plane. It achieves this by accelerating the flow passing over it, and decelerating the flow passing under it. This change in velocity causes a change in pressure, which in turn generates lift.
What is CRM?
What is CRM?
Crew Resource Management (CRM) is the effective use of all available resources for flight crew personnel to assure a safe and efficient operation, reducing error, avoiding stress and increasing efficiency.
Which flight will take the shortest time, from London to New York or New York to London?
Which flight will take the shortest time, from London to New York or New York to London?
New York to London (flying east) would take less time because of the Polar front westerly jet stream.
