Category A: Speed 90 knots or less. Category B: Between 91 and 120 knots. Category C: Between 121 and 140 knots.

What conditions the performance of an aircraft will be the best?

Pressure, temperature, and humidity have a great influence on aircraft performance because of their effect upon density.

What is considered high-performance in aviation?

A high-performance airplane is defined as an airplane with an engine capable of developing more than 200 horsepower. A complex airplane is an airplane that has a retractable landing gear, flaps, and a controllable pitch propeller.

What is aircraft category based on?

According to FAR 97.3, an aircraft’s approach category is based on a published speed called Vref. It’s the approximate speed for flying a stabilized final approach.

How is aircraft performance calculated?

Mach Number:

  1. Formula: Mach Number = Aircraft Speed/Speed of Sound (dependent on altitude)
  2. Example: Aircraft is flying at 30,000′ Speed of sound at 30,000′ = 589.4 knots. The airspeed is 489.3 knots.
  3. Calculate: 489.3/589.5 = 0.83 Mach.

What is the maximum weight for a Category C aircraft?

Once that is done, the aircraft’s maximum landing weight drops from 66,000 lbs to 58,500 lbs and the aircraft becomes Category C. To undo this action, the ASC must be legally removed from the aircraft by logbook action.

What is the aircraft characteristics database (ACD)?

The Aircraft Characteristics Database provides basic aircraft characteristics for common aircraft needed to perform airport design functions. Until an online database is complete, aircraft characteristics data is available from the file below and from Appendix 1 of AC 150/5300-13A, Airport Design.

What is the speed limit for a Category E helicopter?

Category E: 307 km/h (166 kt) or more but less than 391 km/h (211 kt) IAS Category H: see 1.3.10, “Helicopters”. These speeds are the same as used in the United States but the criteria is slightly different. If you have a V SO and a V S1G for your aircraft, you must use the higher of V SO times 1.3 or V S1G times 1.23.

What is the difference between Category B and category E?

Category B: Speed 91 knots or more but less than 121 knots. Category C: Speed 121 knots or more but less than 141 knots. Category D: Speed 141 knots or more but less than 166 knots. Category E: Speed 166 knots or more. In the U.S., the maximum speed for determining an approach category is also the maximum speed for maneuvering.
