A line of latitude.
What is an anti-servo tab?
What is an anti-servo tab?
An anti-servo tab works in the opposite way to a servo tab.
It deploys in the same direction as the control surface, making the movement of the control surface more difficult and requires more force applied to the controls by the pilot.

The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The Boeing 737 has an all moving horizontal stabilizer.
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).
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)
What is a Mach trimmer?
What is a Mach trimmer?
A Mach trimmer is a system that artificially corrects for Mach tuck.
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
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.
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)
