Approach category speeds are defined by which formula?
Approach category speeds are defined by which formula?
This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.
The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.
What is induced drag?
What is induced drag?
Induced drag and its wing tip vortices are a direct consequence of the creation of lift by the wing.
Since the Coefficient of Lift is large when the Angle of Attack is large, induced drag is inversely proportional to the square of the speed whereas all other drag is directly proportional to the square of the speed.
The effect of this is that induced drag is relatively unimportant at high speed in the cruise and descent where it probably represents less than 10% of total drag. In the climb, it is more important representing at least 20% of total drag. At slow speeds just after take off and in the initial climb, it is of maximum importance and may produce as much as 70% of total drag.
Finally, when looking at the potential strength of wing tip vortices, all this theory on induced drag must be moderated by the effect of aircraft weight. Induced drag will always increase with aircraft weight.
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.
What do you prefer, a high or low wingload?
What do you prefer, a high or low wingload?
The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
Yes, some directional control as we still have two functioning engines.
How do you convert between lbs and kg?
How do you convert between lbs and kg?
1kg = 2.2lbs
How would you load an aircraft for max range?
How would you load an aircraft for max range?
The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.
You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).
Why do some airplanes have dihedral wings?
Why do some airplanes have dihedral wings?
Dihedral provides:
Lateral stability (during a roll) Wing clearance, wingtip to ground has more space
What sort of weather would you find at an occluded front?
What sort of weather would you find at an occluded front?
Low pressure weather, unstable weather.
