What is Vmu?
What is Vmu?
Vmu is the minimum unstick speed.
It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff. Lift-off is not possible prior to reaching this speed.
Vmu is not an operational speed and is established in flight testing only.
What are the advantages of an all moving/variable incidence tailplane?
What are the advantages of an all moving/variable incidence tailplane?
This provides pitch manoeuvrability.
Longitudinal balancing by the trim system.
How does anti-skid work?
How does anti-skid work?
Antiskid has a detection system that senses the moment a wheel stops rotating.
Once it senses that the wheel is not rotating, the antiskid system releases brake pressure. This allows the wheel to regain traction with the surface, so that break application can be resumed and prevents complete loss of controllability.
Why do we calculate mass and balance?
Why do we calculate mass and balance?
To be within aircraft design limitations with regards to:
Structural limitations
Stability
Take-off and landing performance
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 do you know about carb icing? Would you experience it today?
What do you know about carb icing? Would you experience it today?
Carb icing can occur in the engine induction system and in the carburettor of piston engines.
Regarding the second question, mention the conditions in which carb icing can occur and if it would be possible on that particular day.
Conditions for carb icing: when OAT is between -10 & +30, with high humidity (greater than 40%) and/or visible moisture.
What are the disadvantages of a swept wing?
What are the disadvantages of a swept wing?
Swept wings have:
-
Poor lift qualities
-
Higher stall speeds
-
Speed instability at low speeds
-
A wing-tip stalling tendency
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 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 is wing loading?
What is wing loading?
Wing loading is the loaded weight of the aircraft divided by the area of the wing.
The faster an aircraft flies, the more lift is produced by each unit area of the wing. Correspondingly, the landing and take-off speeds will be higher and the high wing loading also decreases maneuverability.
