Piper PA-28R-201 Arrow — Instrument Checkride Guide

What makes the Arrow a complex aircraft and why does it matter for IFR?

The Arrow is a complex aircraft under 14 CFR 61.1 because it has retractable landing gear, wing flaps, and a constant-speed propeller — all three features are required for the classification. Before acting as PIC in any complex aircraft, 14 CFR 61.31(e) requires ground and flight training in a complex airplane and a one-time logbook endorsement from an authorized instructor. The DPE will ask to see this endorsement and will verify it against your logbook at the start of the oral exam.

For an IFR applicant, the complex designation adds two major system areas — the landing gear and the constant-speed propeller — directly into the ACS task II.A knowledge requirements. These are not optional topics that a DPE might skip. Expect the oral exam to open or close with a systems walk-through that specifically targets how these systems interact during approach, go-around, and emergency scenarios.

How does the retractable gear system work and what is the emergency extension procedure?

The PA-28R uses a hydraulically actuated retractable tricycle gear system. The hydraulic pump is electrically driven and extends or retracts the gear when the pilot moves the gear selector handle to UP or DOWN. Three green indicator lights — one for each gear — illuminate when the respective gear is down and locked. A red indicator light or the absence of green lights signals a gear-not-locked condition.

The gear warning horn activates when the throttle is retarded below a certain power threshold and the gear is not down and locked. The DPE treats this audible warning as a required knowledge point: what triggers it, what it means, and whether silencing it is ever appropriate.

Emergency gear extension is a required knowledge element for the Arrow checkride. The PA-28R is equipped with a manual backup system — the specific procedure varies by aircraft year and must be verified in the POH for the individual aircraft. At the conceptual level, emergency extension bypasses the hydraulic system and allows gravity and airflow to assist in lowering the gear, followed by positive locking verification via the green indicator lights.

• Three green lights = each gear down and locked; confirm all three before every landing
• Gear warning horn = throttle retarded below threshold with gear not down — treat as an immediate action item
• Emergency extension: a manual backup procedure is installed; exact steps are aircraft-specific — know your POH
• After emergency extension, confirm gear position via indicator lights and perform a low pass if any gear position is uncertain
• The DPE may simulate a hydraulic failure and ask you to walk through the emergency extension concept

How does the constant-speed propeller system work and what failure modes does the DPE test?

The Arrow is equipped with a constant-speed propeller controlled by a propeller governor. The governor maintains a pilot-selected RPM by adjusting propeller blade pitch — increasing pitch (coarser) to absorb more power as airspeed or throttle increases, and decreasing pitch (finer) to maintain RPM when power is reduced. The pilot controls RPM via the blue propeller control in the cockpit, separate from the throttle (manifold pressure).

Engine management with a constant-speed prop follows a specific sequence to protect the engine: when increasing power, advance the throttle first, then increase RPM; when reducing power, reduce RPM first, then pull back the throttle. Reversing this sequence can cause overboosting or excessive stress on engine components. The DPE will ask you to explain this sequence and the reason behind it.

The governor relies on engine oil pressure to function. Per the Airplane Flying Handbook (FAA-H-8083-3C) , a loss of oil pressure to the governor typically causes the propeller to move toward its default pitch, which on most installations is high RPM (fine pitch). The practical effect is a runaway RPM increase accompanied by a drop in manifold pressure. Reference your specific aircraft's POH emergency procedures — the DPE expects you to know the concept and to locate the written procedure in your aircraft documentation.

What is the Arrow's automatic gear extension system?

Certain PA-28R variants were delivered with an automatic gear extension system as a factory option. This system monitors airspeed and automatically deploys the landing gear when the aircraft slows below a manufacturer-set threshold, providing a backup layer against gear-up landing accidents. The system is not present on all Arrows — verify your specific aircraft's equipment list and AFM.

The DPE will probe this system at a conceptual level rather than asking for the exact actuation airspeed, which varies by aircraft. The important points are: the system is a backup, not a replacement for the normal gear-down-and-locked check; the pilot remains responsible for verifying gear position via the three green lights before landing; and the system can be disabled if it malfunctions.

Do not cite activation airspeeds in the oral exam unless you are reading directly from your aircraft's POH. Stating a number from memory that differs from your specific aircraft's documentation is a reliability error the DPE will note.

How does the Arrow's fuel system work?

The PA-28R shares the PA-28 family's fuel system architecture. Two independent wing tanks feed the engine through a selector with LEFT, RIGHT, and BOTH positions. As a low-wing aircraft, the Arrow cannot gravity-feed fuel — the engine-driven fuel pump is the primary source of fuel delivery, with an electric boost pump required for engine start, takeoff, landing, and as backup if the engine-driven pump fails.

This architecture is a frequent DPE question for any low-wing aircraft and is tested under the applied-knowledge standard of ACS task II.A . Understand the reason the boost pump is ON for takeoff and landing: these are the highest-risk phases of flight where an engine-driven pump failure would otherwise leave the engine without fuel delivery before the pilot could react. The boost pump provides immediate backup flow, not just redundancy.

What vacuum system and partial-panel considerations apply?

An analog-panel Arrow uses an engine-driven vacuum pump to power the attitude indicator and directional gyro (heading indicator). The Instrument Flying Handbook (FAA-H-8083-15B) dedicates significant coverage to vacuum system failure as one of the most serious partial-panel emergencies in single-engine IFR flight. The vacuum pump is a wear item — it can fail without warning, and the first indication is often a slow, imperceptible erection of the gyroscopic instruments rather than an immediate flag.

The DPE will test partial-panel proficiency both in the oral exam (describe the failure indications and your scan) and in the flight portion (partial-panel approaches and unusual attitude recoveries). Know which instruments are vacuum-powered and which are not: the turn coordinator is typically electrically powered and remains functional after a vacuum failure — it becomes your primary bank reference under partial-panel.

The pitot-static instruments (airspeed, altimeter, vertical speed) are independent of both the vacuum and electrical systems and remain available under most failure scenarios, making them the backbone of the partial-panel scan.

What avionics suites are common in the Arrow and what IFR approaches are available?

The Arrow has been produced across several decades and can be found with a wide range of avionics configurations, from analog dual-nav/comm stacks to modern glass panels with integrated GPS navigators. The installed equipment — not the airframe type — determines which approach types the aircraft can legally fly.

Before the checkride, verify your aircraft's equipment list and all applicable AFM supplements. The DPE expects you to describe exactly what equipment is installed and what its IFR limitations are — not a generic description of the Arrow type.

VOR receiver currency under 14 CFR 91.171 and equipment requirements under 14 CFR 91.205 apply regardless of which avionics suite is installed.
