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 frequency range and band is an NDB in?
What frequency range and band is an NDB in?
Frequency range from 200-1750kHz, medium and low range frequency bands.
Why is a great circle the shortest distance between two points?

What are the lift qualities of a swept wing?
What are the lift qualities of a swept wing?
Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.
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 is the speed of sound at sea level according to ISA?
What is the speed of sound at sea level according to ISA?
662 kts
Local speed of sound = 39 x √(Temperature in Kelvin)
15°C in Kelvin is (15 + 273) = 288
So the local speed of sound = 39 x √288 = 662 kts
Are swept wings effective?
Are swept wings effective?
Swept wings are designed to be the most effective at high speeds. At low speeds, a swept wing produces less lift than its straight counterpart.
Can you explain what a coastal breeze is?
Can you explain what a coastal breeze is?
A coastal breeze is a wind from the sea that develops over land near coasts.
It is formed by increasing temperature differences between the land and water; these create a pressure minimum over the land due to its relative warmth, and forces higher pressure, cooler air from the sea to move inland.
Generally, air temperature gets cooler relative to nearby locations as one moves closer to a large body of water.
How do you get out of a spiral dive on a Cessna?
How do you get out of a spiral dive on a Cessna?
-
Unload. Make sure you are no longer 'pulling G's'
-
Roll wings level
-
Power Reduce the power to avoid overspeeding.
-
gently pull back on the control wheel to ease out of the dive.
When slowed down to a safe airspeed apply throttle as needed.
(N.b.: Do not confuse a spiral dive with a spin)
