Inspired by my upcoming Commercial checkride, I’ve been working on improving the precision of my flying. I’ve been having problems with float in my practice spot landings, and I think this is because I’m not modifying my final approach speed based on my actual operating weight. I believe the 77 kts recomendation for short field landing is at max gross. Since 77kts is 1.3 x Vs0, that suggests that landing single pilot with minimum VFR fuel reserves (2519 pounds in my plane) the Vref would be only 67kts. Using an appropriate figure when light has solved my float problem.
I’m working on a table of key Vspeeds for different weights. I’ve characterized the plane as min fuel, fuel to tabs, or full fuel, and single, dual or max gross. I’ve filled in all the figures I can from the POH or extrapolations. I’ve stuck this table into my checklists.
I’d appreciate it if anyone has comments on what I’ve got, or can figure out how to fill in the blanks I’ve left. I’m especially baffled by the BestGlide figures; I still don’t know why it doesn’t scale with Vs0 as in other planes. Anyway, the table I’m now using is quoted below:
Dual Full Fuel
Dual Fuel to Tabs
Dual min fuel
Single Pilot Full Fuel
Single Pilot Fuel:Tabs
Single Pilot VFR Day min fuel
