In multiline formulas, I often find myself inserting extra vertical space (\\[...]) between lines (especially when there are many superscripts and subscripts). I guess a certain amount of manual spacing will always be necessary, but if I could increase the default that would decrease the amount of fiddling necessary for many of my documents.

How can I increase line spacing in equations, leaving normal text unaffected?

The vertical space between the lines for all math expressions are controlled by the dimension \jot. (I know the name isn't very intuitiv).

Here an example.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
 \ddot{x}_1+\ddot{x}_2 &= u \\
 x(0) &= \dfrac{27}{4} 
\end{align}

\addtolength{\jot}{10pt}
\begin{align}
 \ddot{x}_1+\ddot{x}_2 &= u \\
 x(0) &= \dfrac{27}{4}
\end{align}
\end{document}
