Always make sure to update yourself with the latest information on these type of questions.
CFM56-7 series with a max takeoff thrust of 27,300lb.
These engines have higher thrust, improved efficiency, and lower maintenance costs than its predecessor, the CFM56-3 series.
180 minutes extended range (ETOPS).
Bypass ratio 5.5:1
At high altitudes, what speed do aircrafts climb on?
At high altitudes, what speed do aircrafts climb on?
Mach number
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
What is the difference between angle of attack and angle of incidence?
What is the difference between angle of attack and angle of incidence?
Angle of attack is the angle between the chord of the aerofoil and the relative airflow.
Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
A precision approach uses both lateral (from left to right) and vertical guidance. A non-precision approach only uses lateral guidance.
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
What does a Mach trimmer do?
What does a Mach trimmer do?
A Mach trimmer automatically compensates for Mach tuck above Mcrit.
What is the speed of sound at sea level according to ISA?
What is the speed of sound at sea level according to ISA?
662 kts
Local speed of sound = 39 x √(Temperature in Kelvin)
15°C in Kelvin is (15 + 273) = 288
So the local speed of sound = 39 x √288 = 662 kts
If in a go-around, which take-off stages will still apply?
If in a go-around, which take-off stages will still apply?
None. The go around procedure is distinct from the take off procedure. You will still have an acceleration altitude, but you will not have a screen height, V1, Vr, V2, flap retraction altitude, etc.
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.
