PERFORMANCE & LIMITATIONS

Question 1

V Speeds given in the AFM/POH apply to what kind of conditions

Answer 1

• apply to sea level
• standard day conditions (15 degrees C, 59 degrees F, 29.92 inHg, standard lapse rate minus 2 degrees C per 1000 ft.)
• max T/O weight

Question 2

Accelerate-stop distance

Answer 2

• runway length required to accelerate to a specified speed like VR, experience engine failure, & bring the a/c to a complete stop

Question 3

Accelerate-go distance

Answer 3

• horizontal distance required to continue T/O & climb 50 ft. assuming engine failure at VR
• we don’t have this because our performance isn’t good enough to warrant it

Question 4

Climb gradient

Answer 4

• the rate at which an aircraft gains altitude in relation to how far it travels horizontally
• expressed as a percentage
• 1.5% climb gradient is like saying one & one-half ft. per 100 ft.

Question 5

Rate of climb

Answer 5

• altitude gain per unit of time

Question 6

All engine service ceiling

Answer 6

• highest altitude where the a/c can maintain steady rate of 100 fpm with both engines operating
• when climb is not longer possible when all engines are at full power

Question 7

OEI service ceiling

Answer 7

• is reached when the a/c can no longer maintain a 50 fpm rate of climb w/ OEI
• absolute ceiling is when climb no longer possible when operating full power & other engine is properly feathered

Question 8

OEI min fix altitude

Answer 8

• altitude at which a/c can be fixed incase an OEI event
• run through checklist & troubleshoot

Question 9

OEI min maneuver altitude

Answer 9

• the lowest altitude at which a pilot can safely execute a maneuver or continue a climb after an engine failure
• ensuring adequate obstacle clearance and compliance with climb gradients

Question 10

Factors that affect flight

Answer 10

• weight & balance
• CG
• density altitude
• temperature
• runway lengths, slope, & conditions
• terrain & obstacles

Question 11

IAS

Answer 11

• airspeed that appears on the airspeed indicator in the cockpit
• measured by the aircraft’s pitot-static system

Question 12

CAS

Answer 12

• indicated airspeed corrected for instrument and positional errors

Question 13

TAS

Answer 13

• calibrated airspeed corrected for nonstandard temperature and pressure

Question 14

GS

Answer 14

• TAS corrected for wind

Question 15

EAS (Equivalent)

Answer 15

• calibrated airspeed corrected for high-speed compression errors

Question 16

What impact does gear down have on climb performance?

Answer 16

• AFM 3-16
• Significant climb performance penalties can result from gear, flap, or windmilling prop drag
• LDG gear extended/Flaps UP -250 ft/min.
• flaps 25/gear down -490 ft/min.
• flaps full/gear down -525 ft/min.
