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.
Explain what coffin corner is and what happens when reaching the coffin corner?
Explain what coffin corner is and what happens when reaching the coffin corner?
Occurs at absolute ceiling where low speed buffet and high speed (Mach) buffet are coincident.
When reaching the coffin corner, both increasing and decreasing the corner speed will result in a loss of control (either the aircraft stalls, or mach buffeting starts).
Why is a great circle the shortest distance between two points?
Why is a great circle the shortest distance between two points?
The track changes constantly.
If you have a fire from the engine in the Warrior, what do you do?
If you have a fire from the engine in the Warrior, what do you do?
On the Warrior, I would perform the following items:
throttle closed mixture closed fuel selector off fuel pump off magnetos off (mayday + 7700 if time permits) and check if fire is out heater defrost off batt alt switches off top door latch unlatch seat belts erect secure and make a forced landing
What is radiation fog?
What is radiation fog?
Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).
Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.
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.
Being an excellent pilot, if I can fly at VMCA, do I need a V2 speed?
Being an excellent pilot, if I can fly at VMCA, do I need a V2 speed?
Yes, for safety you will need a V2 speed.
On a tapered wing, where would the stall occur first?
On a tapered wing, where would the stall occur first?
At the tip as downwash and spanwise flow effect the angle of attack at each section, but because of the tapered wing the effective angle of attack near the tips is greater than that near the center.
What is Mcrit?
What is Mcrit?
Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.
Where is thrust produced in a gas turbine engine?
Where is thrust produced in a gas turbine engine?
Mostly in the fan, but also from the exhaust nozzle duct.
