What sort of weather would you find at an occluded front?
What sort of weather would you find at an occluded front?
Low pressure weather, unstable weather.
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:

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.
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 is wing loading?
What is wing loading?
Wing loading is the loaded weight of the aircraft divided by the area of the wing.
The faster an aircraft flies, the more lift is produced by each unit area of the wing. Correspondingly, the landing and take-off speeds will be higher and the high wing loading also decreases maneuverability.
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 is the relevance of the mass and balance document?
What is the relevance of the mass and balance document?
It’s an official document for the safety of the flight.
A copy of this document needs to remain on the ground.
How does TCAS work?
How does TCAS work?
TCAS works by sending interrogations to other aircraft's transponders.
The transponder will reply to the interrogation in a similar way it responds to radar. From the time difference between the interrogation and the reply, the distance to the other aircraft is calculated. The reply itself contains the altitude of the other aircraft.
The distance and the altitude difference with the other aircraft is tracked to identify a trend which may result in a TA or eventually a RA.
What is the typical range of an NDB?
What is the typical range of an NDB?
Average range over land 20 - 25 miles.
Range for an NDB can be calculated with:
2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)
What is an isobar?
What is an isobar?
A line on a meteorologic chart that joins places of equal sea level pressure (QNH).
