Alert Height question on B737 NG
Hello Everyone,
I just finished off my CAT2/3 checkout on simulator session and still getting things mixed up on usage of alert height.
I tried to look up on FCOM and saw explanation on Fail passive system specific to our company's 737 model and it was so clear. However in what ways could I confirm that I can use alert height on B737 NGs if not, then the phrase stating 'not allowed to use alert height' ?
Also, the planes is manufactured and certified in U.S. so that is why the alert height applied to 737 worldwide because of its origin?
I also checked out the AC120 on CAT2/3 approaches and I am not sure where to find out the reference on those mentioned above.
