Pesawat terbang yang lebih ringan dari udara disebut [[aerostat]], yang masuk dalam kategori ini adalah [[balon]] dan [[kapal udara]]. Aerostat menggunakan gaya apung untuk terbang di udara, seperti yang digunakan [[kapal laut]] untuk mengapung di atas [[air]]. Pesawat terbang ini umumnya menggunakan gas seperti [[helium]], [[hidrogen]], atau udara panas untuk menghasilkan gaya apung tersebut. Perbedaaan balon udara dengan kapal udara adalah balon udara lebih mengikuti arus [[angin]], sedangkan kapal udara memiliki sistem propulsi untuk dorongan ke depan dan sistem kendali.

===The Lift Equation===
The poor lift of the gliders led the Wrights to question the accuracy of Lilienthal's data, as well as the "[[John Smeaton|Smeaton]] coefficient" of air pressure, which had been in existence for over 100 years and was part of the accepted equation for lift.

|+ '''The Lift Equation'''
|<math>L = k\;S\;V^2\;C_L</math>
L = lift in pounds<br>
k = coefficient of air pressure (Smeaton coefficient)<br>
S = total area of lifting surface in square feet<br>
V = velocity (headwind plus ground speed) in miles per hour<br>
C<sub>L</sub> = coefficient of lift (varies with wing shape)
|}
===Lift coefficient===
If the lift coefficient for a wing at a specified angle of attack is known (or estimated using a method such as [[thin-airfoil theory]]), then the lift produced for specific flow conditions can be determined using the following equation:
:<math>
L = \tfrac12\rho v^2 A C_L
</math>
where
* ''L'' is lift force,
* ''ρ'' is air [[density]]
* ''v'' is [[true airspeed]],
* ''A'' is [[planform]] area, and
* <math>C_L</math> is the lift coefficient at the desired angle of attack, [[Mach number]], and [[Reynolds number]]
This equation is basically the same as the [[drag equation]], only the lift/drag coefficient is different.
