I have been looking for a good tutorial for the pmdg 737 800/900I keep finding 737ng referencesIs this really the same generic tutorial or are there difference. Thoughts and reference/links pls.thank youPeter

The 737NG information generally applies to the 800/900 add-on. The changes I noted when upgrading were mostly in the details rather than in the operations.. I consider the 800/900 just an extension to the NG rather than a different aircraft. Use the information freely.
