Performance of the airplane. Sometimes humidity also became a factor that deteriorates the performance of aircraft. Humidity refers to the maximum amount of water content in the atmosphere. When humidity is higher water content in atmosphere will more that will affect the engine power which leads to loss of aircraft performance.

Description
Modern aircraft are designed and built according to strict standards which are laid down by national and international authorities to conform with International Civil Aviation Organisation (ICAO) Annex 8 (Airworthiness). In Europe, aircraft design must conform to European Aviation Safety Agency (EASA) standards.
Aircraft manufacturers publish full details of aircraft performance in the Aeroplane Flight Manual (AFM), together with the approved aircraft operating technique necessary to achieve AFM performance.
Aircraft must be able to operate safely throughout their flight regime in such a way that a safe outcome will result from specified malfunctions (e.g. power unit failure), occurring at any point throughout the flight range.
Take-off and Landing Performance
The maximum aircraft mass at take-off must is the maximum mass calculated for the aircraft type, the runway elevation, length, slope and braking action, and the prevailing weather conditions such that the aircraft can:
- Maintain specified minimum rates of climb after take-off with full power and with one power unit inoperative;
- If a power unit failure is detected during the take-off run, either:
- abandon the take-off and stop within the runway length; or,
- continue the take-off, clearing all obstacles during the climb-out path by a specified margin.
- Continue the flight with one engine inoperative, either returning to the departure airfield, the destination, or a specified alternate airfield clearing all terrain en-route by specified margins.
- Land safely at the departure airfield, the destination or the specified alternate airfield.

The correct operating technique requires the aircraft to be flown at specified configurations, power settings and speeds corresponding to the actual aircraft mass throughout the take-off, initial climb, approach and landing. (Configuration refers to the number of power units operating, whether flaps, landing gear or speed brakes are extended, etc.).
En-route Performance
The manufacturer specifies the maximum operating altitude when full power is available and also when operating with one or more engines inoperative. Climb, cruise and descent data is also published for one or more operating techniques and for all permissible altitudes and temperatures. Data comprises power settings, indicated air speed or Mach No, true air speed and fuel consumption.
