Airbus FCOM is a huge weakness. A tablet version where you can input a single MSN would go a long way towards fixing this problem
But input MSN number solves only small part of the problem. It's also possible to skip pages in pdf. As I love to understand how things work and why it doesn't help. It would be nice to know what's the difference for some systems between 319 and 321 and reason ect. Now the only solution is compare multiple pages to find out that for A321 only difference is that some speed is computed +5 for A321
