===== Why doesn’t my TPFDD-delivered squadron fly the correct number of sorties? =====

The squadron’s sorties is the minimum of (Authorized x PAA Sortie Rate) and (On Hand x Max Sortie Rate).  Since TPFDD increments On Hand but not Authorized, eventually sorties will be constrained by the PAA Sortie Rate.  Consider the extreme example of a squadron receiving 100 aircraft:



^Authorized      ^PAA Sortie Rate	^Sorties^
|24	         |2.0	                |48    |\\ 

^On Hand	^Max Sortie Rate	^Sorties^
^100	        |2.5	                |250  |


In this example, increasing the On Hand quantity will never produce more than 48 sorties per day.  Alternatively, users may increase the authorization:


^Authorized	^PAA Sortie Rate	^Sorties^
|100	        |2.0	                |200|

^On Hand	 ^Max Sortie Rate	^Sorties^
|12	         |2.5	                |30|


In this case, until the quantity On Hand increases enough, the unit will always be driven to produce sorties using the Max Sortie Rate.  

Users should balance these considerations in determining how to set authorization levels.
