Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
Why do the fuel gauges read in kg, but fuel is delivered in litres?
Why do the fuel gauges read in kg, but fuel is delivered in litres?
Because the specific gravity can change with temperature.
Is the tropopause uniform in height? If not, what height is it at the pole and the equator?
Is the tropopause uniform in height? If not, what height is it at the pole and the equator?
No, tropopause at the pole is lower (30.000ft) than at the equator (56.000ft)
What are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
What are the G-limits of the Boeing 737-800?
What are the G-limits of the Boeing 737-800?
+2.5G / -1.0G
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
Is the landing gear in the Seneca electrically or hydraulically operated?
Is the landing gear in the Seneca electrically or hydraulically operated?
We are missing the answer.
What are the dangers of flying into thunderstorms?
What are the dangers of flying into thunderstorms?
Dangers of flying into thunderstorms:
Severe wind shear and turbulence (with a risk of structural problems, loss of altitude, loss of airspeed) Severe icing Hail Lightning strikes (with a risk of damage to electrical systems) Radio Communications and Navigation interference from static electricity in thunderstorms
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.
Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.
How accurate are NDB's?
How accurate are NDB's?
NDB’s are stations emitting a signal. There is nothing for them to be accurate about. ADF's on the other hand, when tuned to an NDB need to be accurate within +/- 5 degrees.
