Ballooning Basics Flashcards
How old do you have to be to start ground school?
14
What produces a lower burn rating
a long sustained burn
Why does a long sustained burn produce a lower heat/burn rating?
D/T the inertia of the fuel
What equipment are balloons required to have during flight?
Altimeter, variometer, and fuel quantity
What is absolute altitude?
Height above surface
what is true altitude?
True height above surface
What is pressure altitude?
Altitude adjusted when altimeter is set to 29.92
What is standard pressure altitude?
29.92 and 15 degrees c
What is density altitude?
Pressure altitude corrected for nonstandard temperature and pressure
What is the correlation between adjusting altimeter and altitude?
1 inch = 1,000 feet, moving the dial one inch (say from 29.92 to 30.92) increases altitude 1,000 feet
At What point should all pressures be set to 29.92?
At 18,000 feet MSL
What is indicated altitude?
Altitude read directly from altimeter
How many satellites are needed for an accurate and 3d image?
4
What is magnetic variation?
Angular difference between true poles and magnetic poles
What is magnetic deviation?
Error caused by magnetic disturbances
During a turn while on a north heading what error does the compass indicate?
From the north, the opposite direction is indicated briefly
During a turn while on a south heading what error does the compass indicated?
An exaggerated turn in the correct direction.
What error does your compass indicate if you accelerate?
a brief turn towards the north.
What error does the compass indicate if you decelerate?
A brief turn towards the south.
What can be substituted for 100 hour inspection?
An annual
