Performance Flashcards
V1 is the speed at which it must be possible:
To abort the take off and bring the plane to a stop on the runway plus stopwatch or continue and be at V2 at 35 feet above the departure end of the runway
Vsi represents:
Stall speed or min steady flight speed in a specified config
Definitions of Vr, V3, and Vb would be:
Rotation speed, flap retraction speed, and maximum gust intensity speed
Vref:
Computed approach speed
Vmo:
Maximum operating speed
V1:
Critical engine failure speed
Va:
Manoeuvring speed
Vso:
Stall speed in the landing configuration
V2:
Take off safety speed
Vra:
Turbulence penetration speed
Vb:
Speed for maximum gust intensity
Vmca:
Airborne minimum control speed
What is the take off safety speed of a multi engine aeroplane,
V2
A referenced airspeed obtained after the airplane lifts off and at which the required one-engine-inoperative climb performance can be achieved is designated as:
V2
Which of the following takeoff and landing distances published in the CAP aerodrome charts include the length of the clearway? (LDA, TORA, ASDA, TODA)
TODA
TORA includes:
Just runway. Doesn’t include stopway, or clearway
CFL or balanced field length means the length of runway:
Required for an aircraft to accelerate to critical engine failure speed, experience an engine failure and to either continue the take-off or reject it
The 3 takeoff distances that must be calculated prior to departure are:
115% all engines takeoff, accelerate stop and accelerate go
A slush covered runway will have what effect on V1 and Vr speeds?
V1 will decrease and Vr will remain the same
An upslope runway will have what effect of V1 and Vr?
V1 will increase and Vr will remain the same, however, V1 can never exceed Vr
The T/O 2nd segment climb gradient for a large 2 eng turbine aircraft starts at the time the landing gear is fully retracted and continues until the airplane reaches an altitude above runway of at least 400ft or a specified level off height. The aircraft must maintain a climb gradient of _____ in this climb gradient
2.4%
The T/O final segment climb gradient for turbo prop aircraft (dash8) ends when the airplane reaches the final T/O flight path point at 1500ft. The airplane must be at a speed 38% above stall maintaining a climb gradient of 12ft vertically for every 1000ft horizontally while using:
MCP, with gear up and flaps retracted
Specific air range formula
TAS/FUEL FLOW
SAR is max endurance
Specific ground range formula
GROUND SPEED/FUEL FLOW
High number is better as this is the number of nm flown per lb of fuel burned
SGR is max range
CRFI readings are included in RSC reports when runways are contaminated with:
Ice and snow, slush or wet snow
Payload calculations
MTOW - BOW - FUEL = Payload
MZFW - BOW = Payload
Make sure not over MZFW (should be given on chart)
Check Max ramp weight aswell
Distance to Critical Point
Total trip distance x reduced/3 eng GS back to departure
Over
Reduced/3 Eng GS to departure + reduced/3 Eng GS to destination
Local speed of sound formula
39 x sq root of temp in Calvin (273 - OAT)
First take off segment req
•take off power
•starts at 35ft above runway elev
•ends at gear retraction
•positive climb
•V2 maintained
Second climb segment
•starts at gear fully retracted
•ends at acceleration altitude (not less then 400AAE)
•climb gradient 2.4%
•V2 maintained
•take off power
Third climb segment
•accelerate to flap retraction speed (if applicable) and then to single engine En-Route climb speed
•take off power
•1.2% climb gradient
Final climb segment
•min actual climb gradient of 1.2% to a height of 1500ft above runway, gear flaps retracted and MCP
Which altimeter setting provides better performance? 30.12 or 29.85
30.12, more pressure means more dense air.
How long can a clearway be in Canada?
No more then 1000’
