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.
Why would someone fly a Rhumb Line track?
Why would someone fly a Rhumb Line track?
-
If no IRS/INS/GPS was available, it’s easier to fly a constant heading (but you will need to apply variation).
-
If flying over short distances (as done during your training) the error introduced by flying a rhumb line is insi
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
False glide slope.
What is a wing tip?
What is a wing tip?
A wing tip is the part of the wing that is the most distant from the fuselage of a fixed-wing aircraft.
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 are fusible plugs, where are they used, how do they work, why do we have them?
What are fusible plugs, where are they used, how do they work, why do we have them?
Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.
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.
What navigational instruments does the Boeing 737-800 have?
What navigational instruments does the Boeing 737-800 have?
IRS / GPS / VOR / DME
What is the advantage of a variable pitch propeller? Why not have a fixed propeller?
What is the advantage of a variable pitch propeller? Why not have a fixed propeller?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage. Fixed pitch propellers are easier to produce and maintain, but reach maximum efficient at only one specific airspeed.
How can you calculate Vref?
How can you calculate Vref?
Vref = 1.3 x Vs0 (stall speed in the landing configuration).
