1
Q

Approach categories on aircrafts are based upon?

A

A grouping of aircraft based on a speed of 1.3 times the stall speed in the landing
configuration at maximum gross landing weight. An aircraft must fit in only one category.
If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for
a category, the minimums for the category for that speed must be used. For example, an
aircraft which falls in Category A, but is circling to land at a speed in excess of 91 knots,
must use the approach Category B minimums when circling to land.
• Aircraft Category A <91 Max circling speed 90Kts
• Aircraft Category B 91 / 120 Max circling speed 120Kts
• Aircraft Category C 121 / 140 Max circling speed 140Kts
• Aircraft Category D 141 / 165 Max circling speed 165Kts
• Aircraft Category E >165

Q

What is ETOPS?

A

Extended twin operations. An operator is granted permission to operate a twin engined
aircraft type on flight in which the aircraft is more than 60 minutes away from a suitable
alternative aerodrome in the event that the aircraft suffers an engine failure en route.

Q

Why are Flight Level intervals increased to 2000 ft in non RVSM airspace?

A

Because of altimeter errors (lower air density). Reduced vertical RVSM to 1000ft
separation above FL290 is granted to aircraft with advanced and more accurate
altimeters, usually crowded routes (Trans Atlantic Routes).

Q

What happens if you move C.G from fwd to aft position?

A

It will be tail heavy, and the horizontal tail­plane will have a short memento arm that will
result in the aircraft is longitudinally unstable because it is too tail heavy for the horizontal
tail­plane. Light stick forces for pitch is required. A decreased wing angle of attack which
results in lower induced drag. It will also increase aircraft range.

Q

What is Dutch Roll?

A 
Dutch roll is a type of aircraft motion, consisting of an out­of­phase combination of "tailwagging" and rocking from side to side. This yaw­roll coupling is one of the basic flight
dynamic modes (others include phugoid, short period, and spiral divergence).

Q

Why are wings swept? Advantage / Disadvantage regarding Swept Wings?

A

They are swept to be able to fly at a higher speed. The advantages are: higher Mach rise
speeds and stability in turbulence. Disadvantages are: Poor lift qualities are experienced,
higher stall speeds, a wing tip stalling tendency is particular to a swept wing aircraft
mainly because of the high local Cl loading it experiences.

Q

Effect of Forward C.G.?

A

Longitudinal stability is increased because the aircraft is nose heavy. The aircraft’s pitch
control is reduced because it experiences high stick forces due to the aircraft’s long tailplane moment arm. Increased wing angle of attack, witch will reduce in higher induced
drag. Will reduce aircraft performance and range. The stalling speed will increase

84
What drift would you experience when flying from a low- to a high-pressure system?
In the northern hemisphere you would experience a drift to the left (port) when flying from a low- to a high-pressure system. This is so because the wind circulates clockwise around a high in the northern hemisphere, and therefore, flying toward the center of a high-pressure system, you would have a wind from the right (starboard) causing you to drift to the left (port). In the southern hemisphere when flying from a low- to a high-pressure system, the opposite is true; namely, you would experience a drift to the right (starboard). This is so because in the southern hemisphere the wind circulates clockwise around a low and counterclockwise around a high, and therefore, the airflow/wind experienced will be coming from the left, causing you to drift to the right (starboard
