What are the advantages of fuel injection vs a carburetor?
What are the advantages of fuel injection vs a carburetor?
Fuel injection provides:
-
Fuel free from vaporization ice
-
Better economy through metered delivery
-
More responsive and efficient engine
-
Less maintenance
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 is the purpose of a locator?
What is the purpose of a locator?
To notify the crew of the aircraft of a particular position on the IAP.
Locators have been largely replaced with Distance Measuring Equipment (DME), but they can sometimes be found associated with Outer or Middle Markers where they are referred to as Locator Outer Marker (LOM) or Locator Middle Marker (LMM).
What are the forces acting on an aircraft in flight?
What are the forces acting on an aircraft in flight?
Lift, Drag, Weight and Thrust.
What are the hydraulic systems of the Boeing 737 called?
What are the hydraulic systems of the Boeing 737 called?
Hydraulic system A and hydraulic system B.
What is the average temperature at 25,000ft according to ISA?
What is the average temperature at 25,000ft according to ISA?
-35°C
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 are the effects on the human body in case of depressurisation?
What are the effects on the human body in case of depressurisation?
Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.
Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.
Other possible effects:
-
Baurotrauma
-
Lung damage
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
What is an NDB?
What is an NDB?
Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.
