Effects of warm weather on a light aircraft?

Does the warmer weather make it more difficult to gain altitude etc.? What effect does it have on the aircraft? Is it easier to fly in the colder weather?

1. yes warmer weather is less dense than cold air so you cant get as mush air onto the compresser whent its hot. also thermals (air currents) affect light aircraft .. flying ove a large black tarmac car park will produce a lot of lift
2. Yes, in colder air planes can carry more freight and can climb higher.
3. The air is less dense when warm. Therefore, the amount of lift available for the wing/aircraft is less. Not so much on fixed wing aircraft, but helicopters are very much affected by this. Also, because the air is more turbulent, you feel more BUMPS as you fly on lower altitude. Pretty uncomfortable as you fly over a large parking lot.
4. When the air is warm, it is less dense. Less dense air affects engine power output, as well as the ability of the jet engine or a propeller to produce thrust, making the aircraft perform as if it were at a higher altitude. This means a longer take-off run and more time to climb to altitude. This is true of ALL aircraft. It's much easier to get the most performance out of an aircraft on cold days then warm days. You notice the effects on a light airplane more, but it affects the performance of all aircraft (airplanes, helicopters,balloons) big and small
5. YES, warm weather does make it difficult to climb an aeroplane. It is due to a higher DENSITY ALTITUDE. This is the altitude the aeroplane 'thinks' it is at. The warmer the air, the less it's density, as has been mentioned, and so the aeroplane will perform as though it is flying at a higher altitude. This goes for all aircraft, although as your question suggests, it has a more noticable effect on light aircraft. As for flying in cold air, it is not neccessarily easier, but one will get better performance from the aircraft. This is the reason most heavy lift cargo airliners fly at night, ask any freight pilot about their hours of work:) Night time generally has a lower DENSITY ALTITUDE. There is a formula to work out the density altitude if you would like to know it...
6. In warmer weather, the air is less dense; as a result you: 1. Get less oxygen for the engine to use. 2. Get less airflow to use for lift on the wings. 3. Get less air mass to use as thrust by propellers or fan disks. In colder weather, it's the opposite. It's also easier to fly in colder weather because cold weather typically have weaker winds, but not always.
7. Yes it dose , temperature effects every thing according to the chart below IF: TEMP. INC. DENSITY OF THE AIR DEC. AND PERFORMANCE OF THE A/C WILL DEC OR , IF TEMP. DEC. DENSITY OF THE AIR INC. AND PERFORMANCE OF THE A/C WILL INC.
