What is MDA?

What is MDA?

Minimum decent altitude (non-precision), the lowest altitude, expressed in feet above mean sea level to which descent is authorised on final approach or during circle-to-land maneuvering in execution of a standard instrument approach procedure where no electronic glideslope is provided.

If not visual between MDA and MAPt, a Go-around must be initiated.

Describe the movement of the center of pressure with varying angle of attack.

Describe the movement of the center of pressure with varying angle of attack.

The Center of pressure position is dependent of the angle of attack. As the angle of attack increases the center of pressure moves closer to the leading edge.

If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?

If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?

In the airplane documents, as the airplane is certificated regarding performance to be able to fly blue line speed (or Vyse) in this situation, so I would climb at this speed to ensure minimum obstacle clearance.

How does a stall strip work?

How does a stall strip work?

A stall strip, usually located close to the wing root, causes the airflow to separate at a lower angle of attack and ensures that the wing root stalls before the wing tips.

What is a Rhumb Line?

What is a Rhumb Line?

A line across the surface of the earth that cuts all meridians at the same angle. i.e. a track of constant direction.

A straight line on a Mercator chart.

What errors does an NDB suffer from?

What errors does an NDB suffer from?

NDB errors:

Interference from other NDB’s

  • Static, especially near thunderstorms

  • Night effect Coastal refraction

  • Mountain effect

  • Aircraft quadrantal error

Why are the indications on an FMA preferred over an MCP?

Why are the indications on an FMA preferred over an MCP?

Always make sure to update yourself with the latest information on these type of questions.

CFM56-7 series with a max takeoff thrust of 27,300lb.

These engines have higher thrust, improved efficiency, and lower maintenance costs than its predecessor, the CFM56-3 series.

180 minutes extended range (ETOPS).

Bypass ratio 5.5:1

What is a Great Circle?

What is a Great Circle?

A line of shortest distance between two points on a sphere.

What is profile drag?

What is profile drag?

Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.

It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.

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.
