Open the sheet on the FAA Dynamic Regulatory System (opens in a new tab)

Performance figures (stall speeds, take-off and landing distances, climb, cruise and fuel burn) are in the aircraft's flight manual (POH/AFM), which we cannot reproduce. Always use the flight manual for the aircraft you fly.

This is a United States Federal Aviation Administration sheet. We show it as a US certification document, not as an Australian or New Zealand rule. Units are the sheet's own: pounds, US gallons and quarts, and knots or mph as stated.

How we copied the sheet. Quotes are from our stored text copy of the sheet, taken from the text layer of the FAA's online viewer. We rebuilt lines from the text positions, joined wrapped lines, marked wide gaps between table cells with |, removed page headers and footers, and replaced symbol-font characters with the symbols they print as. Check the original sheet before relying on any figure.

Models not shown. The sheet also covers the first PA-44-180 serial range (section IA) and the PA-44-180T Turbo Seminole. We include the later PA-44-180 section (IB).

COCKPIT

The PA-44-180 limits on an airspeed indicator

Where the sheet gives them in knots, the dial shows Vne as a red line, the caution range from Vno to Vne as a yellow arc, a green tick at Vno and white ticks at the flap limit speeds (Vfe). The sheet gives flap limits, not instrument markings, and the stall speeds where the green and white arcs start are not in it.

PANEL LAYOUT

Classic six-pack

These are example panels drawn by us. They do not show the panel fitted to any Piper PA-44 Seminole. Only the airspeed markings come from this model's data sheet.

  • Marks are drawn at the sheet's speeds in knots IAS.
  • White tick marks the flap limit speed (Vfe) the sheet gives. The sheet gives flap limits, not instrument markings, so the flight manual says where this aircraft's white arc ends.
  • The low ends of the white and green arcs are stall speeds. They come from the flight manual, so we have left them unmarked.
