not. 2.2Byfollowingtheguidancedescribedinthispublicationandonsuccessfulcompletionofthe processes listed, operations offering an Air Service will be provided with a Heliport Certificate; those whichhavebeenidentifiedasprivateuse(notAirServiceoperations),willbeprovidedwitha Helicopter Landing Area Acceptance. 2.3FortheprovisionofAirServiceandprivateuseoperations,referenceshallbemadetoCAR

The FAT0 should be designed for the largest or heaviest type of helicopter that it is anticipated will use the heliport, and account taken of other types of loading such as personnel, freight, refueling equipment, etc.9.2For the purpose of design, it is to be assumed that the helicopter will land on two main wheels, irrespectiveoftheactualnumberofwheelsintheundercarriage,orontwoskidsiftheyarefitted.
