Performance &Limitations
As density altitude increases, aircraft performance does this.
What is decrease
This left-turning tendency is caused by the descending blade on the right producing more thrust than the ascending blade on the left.
What is P-factor?
If the engine fails during takeoff roll, the first action is to…
What is throttle to idle and stop straight ahead
This type of error causes the compass to lag when turning through north and lead when turning through south.
What is northerly turning error
This system provides power to the electrical components when the engine is running
What is the alternator
Three factors that determine density altitude are…
What are pressure(elevation), temperature, and humidity
The torque reaction from the propeller causes the airplane to roll in this direction during takeoff.
What is to the left
If the engine fails after takeoff and there’s no runway remaining, the pilot should…
What is pitch for best glide and land straight ahead
This acronym helps remember compass errors: ANDS stands for
What is Accelerate North, Decelerate South
Fuel from the tanks is delivered to
If the pitot tube becomes blocked but the drain hole remains open, which flight instrument is affected and how?
What is the airspeed indicator, which will read zero
The distance required for takeoff over a 50-foot obstacle increases as this environmental factor rises.
What is temperature (or density altitude)
The tendency of the airplane to yaw left when the tail is raised on takeoff due to a gyroscopic effect.
What is gyroscopic precession
In an electrical fire in flight, the first step is to…
What is turn off the master switch
When on an east or west heading, acceleration causes the compass to show a turn toward this direction in the Northern Hemisphere.
What is north
A carburetor uses this principle of physics to mix fuel and air for combustion.
What is Bernoulli’s principle
On a hot, humid day at a high-elevation airport, the aircraft will require this change to achieve liftoff.
What is a longer takeoff roll (or “higher true airspeed”)
When operating at high power and low airspeed, this combination of four forces causes the airplane to yaw left.
What are torque, P-factor, gyroscopic precession, and spiraling slipstream?
If engine roughness is suspected at low rpm’s, the proper action is…
What is to apply carb heat
The magnetic compass error caused by the difference between true north and magnetic north is called…
What is variation
In a four-stroke engine, the order of operation is
What are intake, compression, power, exhaust
At a constant indicated airspeed, as altitude increases, true airspeed and ground roll do this.
What is both increase
During a climb, the airplane experiences the strongest P-factor under these two conditions.
What are high angle of attack and high power settings
If an engine fire occurs in flight, list the immediate steps the pilot should take.
What are mixture to idle cut-off, fuel selector off, master switch off, cabin heat/air off, and execute an emergency descent and forced landing
This error occurs when the compass is affected by magnetic fields from aircraft wiring or instruments.
What is deviation
If the alternator fails in flight, this component continues supplying power until it is depleted.
What is the battery
