What are the advantages of operating a one aircraft type fleet, why don’t we use an A320 / B737 mixed fleet?

The FMA indicates what system is controlling the aircraft and what mode is operational.
What clearance do MSA values give?
What clearance do MSA values give?
They provide at least 1000ft clearance over obstacles within 25NM of the homing facility.
What is the range of a VOR at 32000ft?
What is the range of a VOR at 32000ft?
Range = 1.23(√H1 + √H2)
= 1.23 * √32000
= 220 nm
What is the typical range of an NDB?
What is the typical range of an NDB?
Average range over land 20 - 25 miles.
Range for an NDB can be calculated with:
2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)
Why is a great circle the shortest distance between two points?
Why is a great circle the shortest distance between two points?
The track changes constantly.
What is adverse yaw?
What is adverse yaw?
When rolling the aircraft the up-going wing will experience more drag than the down-going wing. This will result in a yawing moment that directly opposes the desired direction of turn. (i.e.: rolling left will cause a right yaw.)
Explain the Fohn wind.
Explain the Fohn wind.
A Fohn wind is a warm dry wind that blows down the lee side of a mountain.
Initially, the air temperature cools dry-adiabatically (3°C/1000 ft), until its dew point temperature is reached. Condensation occurs as the air is further forced up the mountain range, resulting in the air cooling saturated-adiabatically (generally considered in the mid-latitudes to be 1.8°C/1000 ft). Clouds and precipitation form. When the air mass reaches the top of the mountain range it has lost a significant amount of its water content and so has a much lower dew point temperature.
As the air then begins to descend down the lee slope of the mountain the compressed air is initially heated saturated-adiabatically, and in effect the direct reverse to the cooling effect on the windward side occurs. As the air continues leeward and downward from the mountain range, the air, now no longer saturated, is heated dry-adiabatically.
The resultant wind is dry and warm giving clear conditions at airfields on the lee side of the mountain range.
The Foehn Effect also may be associated with mountain wave activity.
If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?
If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?
In Newfoundland. With cold weather density increases, therefore you would pick up a higher mass in Newfoundland.
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
A high wing location like the BAE and the Fokker give a natural stable contribution.
This is because the Center of Gravity is underneath the wing, therefore when disturbed the C.G. provides a positive momentum opposite to the distortion.
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.
