Every card names and links the source that controls it. Verify the current source before flight. Use the current regulation when applying a rule.

Get the limits, checklists and procedures for your specific airplane from its current AFM/POH and supplements.

Plan your return to flying.

Bring your experience, aircraft and next flying goal together in an instructor briefing. Keep legal currency, flight review and practical proficiency separate.

What changes for you?

Same training category does not mean the same systems, limits or cockpit habits.

Usable fuel

FROM · Cessna 172S · NAV I/II

53 U.S. gal usable; 56 total. Two wing tanks.

§2, p. 2-11

TO · Piper PA-28-181 · Archer II

48 U.S. gal usable; 50 total in the stock base system.

§1 fuel; §2 p. 2-7

What changes for you: Base planning on usable quantity, actual loading and measured consumption—not the previous airplane's tank size.

Selector and fuel management

FROM · Cessna 172S · NAV I/II

LEFT / BOTH / RIGHT, plus a separate fuel shutoff. BOTH required for takeoff and landing. LEFT or RIGHT limited to level flight.

§2 p. 2-11; §7 fuel system

TO · Piper PA-28-181 · Archer II

LEFT / RIGHT / OFF; no BOTH. Select a tank containing fuel. Use the electric pump for the specified operations and tank changes.

§7 pp. 7-7–7-10; §4 cruise

What changes for you: Moving from BOTH in the C172S: this Archer has no BOTH. Select a tank with fuel and rehearse the tank-change and electric-pump procedure from the Archer checklist.

Flaps

FROM · Cessna 172S · NAV I/II

Electric; 0°, 10°, 20°, 30°. VFE: 110 KIAS through 10°; 85 KIAS beyond 10° through 30°.

§2 p. 2-4; §7 wing flaps

TO · Piper PA-28-181 · Archer II

Manual lever; 0°, 10°, 25°, 40°. VFE 102 KIAS.

§2 p. 2-2; §7 flight controls

What changes for you: Moving from electric flaps to the Archer's manual lever: learn the 10°/25°/40° detents and the cited 102 KIAS extension limit. Check the target position rather than repeating the Cessna hand movement.

These selected differences are study material, not complete checklists. The exact aircraft's current AFM/POH, supplements, placards and instructor checkout control. A base profile does not establish that a particular tail number matches it.
