What is the center of pressure?
What is the center of pressure?
An aerofoil when placed in a flow will (normally) cause said flow to accelerate over the aerofoil and decelerate below it.
This will cause a pressure differential between the upper and lower surface of the aerofoil, and the resultant force will be applied at the center of pressure.
What produces the maximum glide range?
What produces the maximum glide range?
Flying at Vmd. At this speed the aircraft is flying at the maximum ratio of Lift and Drag, maximizing the potential energy consumption in terms of distance travelled.
What performance category was your last aircraft? How are airplanes classified?
What performance category was your last aircraft? How are airplanes classified?
Note: this question was asked to a candidate with previous Seneca experience, make sure to be able to answer this question for your previous aircraft type.
Seneca is class A.
Aircraft are classified according to their Vat.
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.
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 is lift?
What is lift?
Lift is the component of the total aerodynamic force perpendicular to the relative airflow.
Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.
The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The Boeing 737 has an all moving horizontal stabilizer.
What are the G-limits of the Boeing 737-800?
What are the G-limits of the Boeing 737-800?
+2.5G / -1.0G
What can you tell about adiabatic lapse rates?
What can you tell about adiabatic lapse rates?
When considering a volume of air, adiabatic lapse rate is the temperature change that is caused by the vertical movement of the volume, andThe Lapse Rate is the rate at which temperature changes with height in the atmosphere.
The Environmental Lapse Rate (ELR) is according to ISA 2°C per 1000 feet increasing altitude.
For unsaturated air, the lapse rate is 3°C per 1000 feet, this is called the Dry Adiabatic Lapse Rate (DALR).
The Saturated Adiabatic Lapse Rate (SALR) is the rate at which saturated air cools with height and is, at low levels and latitudes, 1.8°C per 1000 feet.
What will happen if the primer of your engine/fuel system kept operating?
What will happen if the primer of your engine/fuel system kept operating?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
