What are wing tip vortices?
What are wing tip vortices?
Wingtip vortices are tubes of circulating air that are left behind a wing as it generates lift.
They are caused by the difference in pressure above and below the wing causing the air to 'escape' from the high pressure area below the wing to the low pressure area above the wing, by rolling around the tip of the wing. This creates a vortex that trails behind the wing.

L = 1/2 * rho * Cl * A * V^2
How does an airspeed indicator work and which errors can an airspeed indicator experience?
How does an airspeed indicator work and which errors can an airspeed indicator experience?
The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case.
The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.
ASI errors can originate and vary from:
Instrument Pressure Density Compressibility Maneuver Blocked pitot static system

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
You are at the end of the runway with the static ports blocked. What will be the reading on the altimeter after departure?
You are at the end of the runway with the static ports blocked. What will be the reading on the altimeter after departure?
The elevation at which the airplane departed from the runway.
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.
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 is there an over boost protection on the Piper PA34 Seneca?
Why is there an over boost protection on the Piper PA34 Seneca?
To protect the engine from blowing up as it is easy to open the throttles to far during take off at sea level.
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
