What is advection fog?
What is advection fog?
Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled.
It is common as a warm front passes over an area with significant snowpack, but it is most common at sea when tropical air encounters cooler waters, including areas of cold water upwelling, such as along the coast of California.
What is Point of No Return (PNR)?
What is Point of No Return (PNR)?
The point during a flight at which an aircraft is no longer capable of returning to the airfield from which it took off due to fuel considerations.
Beyond this point the aircraft must proceed to some other destination.
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.
How can you calculate the range of a VOR?
How can you calculate the range of a VOR?
By using the formula: Range (nm) = 1.23(√H1 + √H2)
H1=height of transmitter (feet)
H2=height of receiver (feet)
What is the formula for Lift?
What is the formula for Lift?
L = 1/2 * rho * Cl * A * V^2
How do you convert litres to kg?
How do you convert litres to kg?
Volume of litres x Specific gravity = weight in kg
How would you navigate if all VOR's and NDB's en route fail?
How would you navigate if all VOR's and NDB's en route fail?
With the IRS/INS/GPS or visually.
What does a Mach trimmer do?
What does a Mach trimmer do?
A Mach trimmer automatically compensates for Mach tuck above Mcrit.
How does an airspeed indicator work and which errors can an airspeed indicator experience?
How does an airspeed indicator work and which errors can an airspeed indicator experience?
The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case.
The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.
ASI errors can originate and vary from:
Instrument Pressure Density Compressibility Maneuver Blocked pitot static system
