What are the major factors that affect aircraft performance?
The primary factors most affected by performance are the takeoff and landing distance, rate of climb, ceiling, payload, range, speed, maneuverability, stability, and fuel economy.
What is operational performance of an aircraft?
What is operational performance of an aircraft? Explanation: Operational performance of an aircraft is the performance of an aircraft which is related to the aircraft above ground level. It includes aircraft cruise angle, altitude, temperature, engine failure, fuel management and also take-off performances.
How is aircraft performance measured?
- Formula: Mach Number = Aircraft Speed/Speed of Sound (dependent on altitude)
- Example: Aircraft is flying at 30,000′ Speed of sound at 30,000′ = 589.4 knots. The airspeed is 489.3 knots.
- Calculate: 489.3/589.5 = 0.83 Mach.
How can aircraft performance be improved?
- 1) Reduce the weight. Reducing unnecessary weight can help in a lot of ways. …
- 2) Move the center of gravity aft. …
- 3) Lean the mixture. …
- 4) Choose the right altitude. …
- 5) Incorporate drag reducing devices.
How does pressure affect aircraft performance?
As pressure decreases, the air becomes less dense or thinner. This is the equivalent of being at a higher altitude and is referred to as density altitude. As pressure decreases, density altitude increases and has a pronounced effect on aircraft performance.
How does high temperature affect aircraft performance?
Flying in the heat
The lower the air density, the faster an airplane must travel to produce enough lift to take off. It takes more runway to reach a higher speed, and depending on how long the airport’s runway is, some airplanes might risk running out of room before reaching sufficient speed.
What is operational KPI?
An Operations Key Performance Indicator (KPI) or metric is a discrete measurement that a company uses to monitor and evaluate the efficiency of its day-to-day operations. These operations KPIs help management identify which operational strategies are effective, and those that inhibit the company.
What is mops in aviation?
A MOPS provides standards for specific equipment(s) useful to designers, manufacturers, installers and users of the equipment. The word “equipment” used in a MOPS includes all components and units necessary for the system to properly perform its intended function(s).
How can airport operations be improved?
- Sharing information across the airport. An airport works much like a relay race where the team performance is dependent upon each individual runner. …
- Better use of what you have. …
- Balancing demand. …
- Getting your sequence right. …
- Being consistently consistent.
How do you calculate performance?
Performance is calculated by dividing your Total Count by Run Time and comparing it to your Ideal Run Rate or Performance = (Total Count / Run Time) / Ideal Run Rate.
What is the lift formula?
The lift equation states that lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A. For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift.
How do you calculate takeoff performance?
Some experienced pilots recommend using the obstacle clearance distance as their anticipated ground roll. Others simply double the book numbers. Using that method, the calculated takeoff run of 962 feet should really be 1,924 feet—and that’s about 84 feet beyond the end of the runway.
What makes an aircraft efficient?
Airplanes are fast and efficient because they can operate in a low friction environment. There are no wheels (at least in flight) that have to be constantly be rolled over the ground, and at higher altitude the air is thinner which reduces air drag dramatically.
How can aircraft engine efficiency be improved?
Reducing the lift-to-drag ratio of an aircraft can make it more aerodynamically efficient and help reduce the aircraft’s weight and fuel use. Engineers are experimenting with innovative designs that will help reduce drag. Ideas include thicker fuselages, which increase airflow, and longer, slimmer wings.
What is aircraft ground time?
Ground time means the time period beginning at the time an aircraft lands and ending at the time an aircraft takes off.
What factors can impact the range of an aircraft?
There are several factors will have effect on the maximum possible range which are aircraft’s mass and speed, density altitude and wind. Increased aircraft mass, increases the drag. This requires greater thrust to balance the drag, which increases the fuel flow and reduces the specific range.
What affects takeoff performance?
They apply various factors, including density altitude, type of operation, runway surface, runway slope and wind to readily determine take-off and landing distances for a particular set of conditions.
How does humidity affect aircraft performance?
Humidity affects the way an airplane flies because of the change in pressure that accompanies changes in humidity. As the humidity goes up, the air pressure for a given volume of air goes down. This means the wings have fewer air molecules to affect as they are pushed through the airmass. Fewer molecules = less lift.
What are the factors that affect the power output of an engine?
- Heat Transfer. The heat is exchanged in both directions between the gases and engine cylinder walls and. …
- Residual Gas. …
- Valve Resistance. …
- Valve Timing. …
- Combustion Time. …
- Incomplete Combustion. …
- Atmospheric Conditions.

a) 90%
b) 92.86%
c) 89.556%
d) 67.35%
View Answer
Answer: b
Explanation: The answer is 92.86%. Given number of passengers travelling = 130, seating capacity=140 and a yield of 7.9.
We know percentage load factor=\(\frac{no. \, of \, passengers \,travelling*distance \,travelled}{no. \,of \, seats*distance \, travelled}\) x 100%
On substituting the values,
Load factor=\(\frac{130*990}{140*990}\) x 100%
Load factor=92.86%.
