Range and Endurance Flashcards
1
Q
What is Specific Air Range (SAR)?
A
Distance an aircraft travels per unit of fuel consumed, in still wind
2
Q
What is Specific Ground Range (SGR)?
A
Ground nautical miles travelled per unit of fuel
3
Q
What is Specific Fuel Consumption (SFC)?
A
The ratio fuel consumption and thrust/power developed
4
Q
What is Gross Fuel Consumption (GFC)?
A
Fuel consumption of an engine measures in quantity per unit time
5
Q
How does SFC change with RPM, temperature and altitude?
A
- Reduces with RPM to an optimal band, then increases again
- Reduces with decreasing temperature
- Reduces with increase in altitude
