If you look at the table of N1 setting for B 737-600, you can see that in one column (for the fixed pressure altitude) , as the OAT temperature rises from the lowest values, the N1 setting for max T/O gets higher and higher, which is logical.
But as you reach around around 100-102 Farenheit, the N1 setting starts to drop to achieve max T/O thrust, which is a kind of puzzle for me. Air gets hotter, density is lower, but you need less N1 to achieve full T/O thrust, then before at the lower temperatures?
Can somebody give a reasonable explanation, please.
