Thanks ... I like easy memory aids ...IPAIDS ... THAT I can use! :first: ( i do that on my untowered radio announcements anyway) ... I just sometimes get the order mixed up or forget altitude/intent ... practice & discipline to follow a fixed order will help!
Although this one is mainly for fixed wings and complex, I still tend to run it through my feeble mind prior to final approach:
G:Gas on the Main Tank
U: Undercarriage (Gear down and Locked)
M: Mixture, Full Rich or as required
P: Pumps on
S: Seat belts and doors secure
