What are the advantages of swept wings?
What are the advantages of swept wings?
Swept wings are:
Better for high speed flight as they have minimal camber and thickness reduce drag and delay Mcrit More stable in turbulence as they produce less lift and as a result they are less responsive to updraughts
Could a Seneca fly to the South of France without stopping for extra fuel?
Could a Seneca fly to the South of France without stopping for extra fuel?
No
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
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
False glide slope.
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
5000 litres
(4 tonnes / 0.8 = 5000 litters)
Why does a swept wing increase Mcrit?
Why does a swept wing increase Mcrit?
A swept wing makes the velocity vector normal to the leading edge a shorter distance than the chordwise resultant.
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)
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
Via INS/IRS/GPS
Does a jet have a critical engine? Why yes or no?
Does a jet have a critical engine? Why yes or no?
No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
