QUESTIONS AND CORRECT ANSWERS
Approach categories on aircrafts are based upon? - CORRECT ANSWER 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 Aaproach Category A? - CORRECT ANSWER <91 Max circling speed 90Kts
Aircraft Category B? - CORRECT ANSWER 91/120 Max circling speed 120Kts
Aircraft Category C? - CORRECT ANSWER 121/140 Max circling speed 140Kts
Aircraft Category D? - CORRECT ANSWER 141/165 Max circling speed 165Kts
Aircraft Category E? - CORRECT ANSWER >165
What is ETOPS? - CORRECT ANSWER 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.
Wha are the various ETOPS categories? - CORRECT ANSWER Normal extended twin
operations (ETOPS) categories, vary between 60 and 180 Minutes.
The first segment on a Takeoff? - CORRECT ANSWER First Segment: The Climb from 35 feet
point until the landing gears are fully retracted. Conditions in this segment are:
- landing gear extended
- flaps in T/O position
- Speed = V2
,- Climb gradient for 2 engine A/C = Positive
- Climb gradient for 4 engine A/C = 0.5%
- Takeoff power
The second segment on a Takeoff? - CORRECT ANSWER Second Segment: Climb from gear
retraction point until a height of 400 feet is reached. conditions in this segment are:
- gears retracted
- flaps in T/O position
- speed = V2
- Climb gradient 2 engine a/c 2.4%, and 4 engine a/c 3.0%
- takeoff power
The third segment on a Takeoff? - CORRECT ANSWER Third Segment: Its the horizontal
distance covered after the second segment until the flap retraction speed is reached, to raise the flaps
plus the distance required to accelerate the aircraft to the flaps up climb speed. It consists of two parts:
First part of 3rd segment: Distance covered before flap retraction, accelerating to flap retraction
speed. The conditions are:
- gears retracted
- flaps in t/o position
- speed increasing from v2 to flap retraction speed
- Climb gradient 2 engine a/c 1.2%, 4 engine a/c 1.7%
- takeoff power
Second part of 3rd segment: Distance covered after flap retraction, accelerating to final t/o climb
speed. the conditions are:
- gears retracted
- flaps retracted
- speed, accelerating from flaps retraction to final t/o climb speed
- Climb gradient 2 engine a/c 1.2%, 4 engine a/c 1.7%
- maximum continuous power
,The fourth segment on a Takeoff? - CORRECT ANSWER Fourth Segment: the Climb from 400
feet till 1500 feet is reached, after the end of third segment operating with max continuous power. The
conditions are:
- gears retracted
- flaps retracted
- speed = final t/o climb speed
- max continous power
- Climb gradient 2 engine a/c 1.2%, 4 engine a/c 1.7%
IFR and RVSM Flight levels? - CORRECT ANSWER 0-179 Magnetic Track, Degrees odd
numbers, 180-359 Even numbers
Vertical Separation is only 1000 ft up to FL290 and 2000 ft above FL290 in non-RVSM airspace and
only 1000 ft in RVSM airspace i all levels.
Why are Flight Level intervals increased to 2000 ft in non RVSM airspace? - CORRECT
ANSWER 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).
What are the lights and markings on a taxiway? - CORRECT ANSWER Blue edge and green
center. Continued yellow line.
How long runway remaining when RWY centerline light turns solid red? - CORRECT
ANSWER Red for last 1,000 ft (305 m)
How long runway remaining when RWY centerline light turns alternating red and white? -
CORRECT ANSWER 3000 ft remaining
What happens if you move C.G from fw to aft position? - CORRECT ANSWER 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.
, What is Dutch Roll? - CORRECT ANSWER Dutch roll is a type of aircraft motion, consisting
of an out-of-phase combination of "tail-wagging" and rocking from side to side. This yaw-roll
coupling is one of the basic flight dynamic modes (others include phugoid, short period, and spiral
divergence)
How many % to be considered a contaminated runway? - CORRECT ANSWER 25%
Why are wings swept? Advantage / Disadvantage regarding Swept Wings? - CORRECT
ANSWER Advanteages:
- Increases Mcrti
- Increase MACH during cruise
- Greater stability in turbulence
Disadvantages:
- Poor lift qualities
- Higher stall speed
- Speed instability at lower speeds
- Wing tip stall tendency which causes nose up tendency
An Aircraft is climbing at constant Mach Number what will happen with TAS? - CORRECT
ANSWER TAS will decrease
An aircraft climbs at constant TAS through an inversion, will the RAS and Mach number increase,
decrease or stay the same? - CORRECT ANSWER Mach Number will decrease, RAS will
decrease
What is Climb Gradient? - CORRECT ANSWER The rate, expressed as a percentage, of the
change in geometric height divided by the horizontal distance traveled in a given time.
Definition of Wet Runway? - CORRECT ANSWER A runway is considered "wet" when there
is sufficient moisture on the surface to appear reflective, but. without significant areas of standing
water. A runway surface that appears darkened by residual moisture (damp runway) shall not be
considered wet or contaminated except as outlined below.
