What effect does a wet runway have on V1?
What effect does a wet runway have on V1?
V1 is lower when the runway is wet than when the runway is dry, because of the longer ASDR on a wet runway.
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
Which flight will take the shortest time, from London to New York or New York to London?
Which flight will take the shortest time, from London to New York or New York to London?
New York to London (flying east) would take less time because of the Polar front westerly jet stream.
What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
What navigational instruments does the Boeing 737-800 have?
What navigational instruments does the Boeing 737-800 have?
IRS / GPS / VOR / DME
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
What are fusible plugs, where are they used, how do they work, why do we have them?
What are fusible plugs, where are they used, how do they work, why do we have them?
Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.

Swept back wings
Where does a swept wing stall first?
Where does a swept wing stall first?
At the tip
What is a high bypass ratio engine?
What is a high bypass ratio engine?
In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.
A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.
