What is drag?
What is drag?
Drag is the component of the total aerodynamic force parallel to the relative airflow.
Drag is generated by any body placed in a flow and it's composed of friction, form, and pressure drag.
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.
Why do some airplanes have dihedral wings?
Why do some airplanes have dihedral wings?
Dihedral provides:
Lateral stability (during a roll) Wing clearance, wingtip to ground has more space
Why are NDB powered so that they only have a range between 15-25 miles?
Why are NDB powered so that they only have a range between 15-25 miles?
NDB’s can suffer from a lot of errors.
Is the landing gear in the Seneca electrically or hydraulically operated?
Is the landing gear in the Seneca electrically or hydraulically operated?
We are missing the answer.
How do you convert litres to kg?
How do you convert litres to kg?
Volume of litres x Specific gravity = weight in kg
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
No because it is warmer, according to ISA temperature should be -55°C
What are the dangers of flying into thunderstorms?
What are the dangers of flying into thunderstorms?
Dangers of flying into thunderstorms:
Severe wind shear and turbulence (with a risk of structural problems, loss of altitude, loss of airspeed) Severe icing Hail Lightning strikes (with a risk of damage to electrical systems) Radio Communications and Navigation interference from static electricity in thunderstorms
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
Explain V1, V2, VR, VMCA and VMCG
Explain V1, V2, VR, VMCA and VMCG
V1 is the decision speed (sometimes referred to as critical engine speed or critical engine failure speed) by which any decision to reject a takeoff must be made.
V2 is the takeoff safety speed which must be attained at the 35 ft height at the end of the required runway distance. This is essentially the best one-engine inoperative angle of climb speed for the airplane and is a minimum speed for flight in that condition until at least 400 ft above the ground. V2 shall be at least 1.1 times VMCA, and no less than 1.2 times VS.
Vr is defined as the speed at which the rotation of the aircraft should be initiated to takeoff attitude.
VMCA is the minimum control speed in the air and is defined as the minimum speed, whilst in the air, that directional control can be maintained with one engine inoperative (critical engine on two engine aerolanes), operating engine(s) at takeoff power and a maximum of 5 degrees of bank towards the good engine(s).
VMCG is the minimum control speed on the ground and is defined as the minimum speed, whilst on the ground, that directional control can be maintained, using only aerodynamic controls, with one engine inoperative (critical engine on two engine airplanes) and takeoff power applied on the other engine(s).
