Helicopter Private Pilot ACS – Changes to Preflight Preparation Tasks

Effective May 31st, 2024 the FAA Helicopter Private PTS (along with Commercial, Instrument & CFI) will be replaced by the new FAA Helicopter Private Pilot ACS (Airman Certification Standards).

Before taking the knowledge test or practical exam (checkride) you should be looking through every element in every applicable task and ask yourself “Am I confident about this?” And if the answer is “No“, use your instructor and the task references to help you learn/practice what the FAA wants you to know, consider & do to pass the exams. Below are just some of the key differences from the PTS for each task in the new Helicopter Private Pilot ACS , I. Preflight Preparation Area of Operation (AOO).

General ACS Changes

But first, if the ACS is completely new to you, before reading the specific changes below check out our ACS overview article and ACS overview video covering the new ACS code system, task structure, required elements, changes to special emphasis areas, risk management and more.

Helicopter ACS Private Pilot, Part 1 – The BIG Changes

Preflight Preparation Renamed Tasks

Task A is renamed from Certificate and Documents to Pilot Qualifications because the task items that related to the aircraft certificates and documents were moved into Task B (Airworthiness Requirements) and Task A became pilot-focused. See more information on Task A and Task B below.

Task H was renamed Human Factors from Aeromedical Factors, but the content area is mostly the same, see full details on Task H below.

Helicopter Private Pilot ACS Preflight Preparation Tasks

Task A – Pilot Qualifications

Helicopter Private Pilot ACS Preflight Preparation Task A – Pilot Qualifications

As already mentioned, Task A was renamed from Certificates and Documents to Pilot Qualifications, because the PTS section on aircraft airworthiness was moved from Task A into Task B. Because of that change, the references related to the aircraft were removed (Part 43 & the POH/RFM) but also Part 67, which seems odd as it relates to pilot medical certificates.

The note regarding the examiner using a scenario for Tasks C, D, E & F was removed, but this is largely irrelevant as in the ACS the examiner will be using scenarios as much as possible throughout the entire checkride anyway.

References

New references were add to Part 68 and the AC 68-1 which covers BasicMed. Also, due to the new Risk Management section of ACS tasks, all tasks will now have a reference to the FAA Risk Management Handbook 8083-2.

Knowledge

The knowledge section is mostly similar, but new elements include, temporary disqualifications to medical certificates and Part 69 (BasicMed) privileges & limitations.

Risk Management

In the new Risk Management section, consider scenarios that might pose risks associated with flight proficiency versus currency and flying an unfamiliar helicopter or unfamiliar instruments and avionics. For example, you become a private helicopter pilot, and you learned to fly in an R22 helicopter. Someone asks you to fly their new Cabri G2…Can you legally? Are there some risks involved? What are they and how could you mitigate them?

Task B – Airworthiness Requirements

Helicopter Private Pilot ACS Preflight Preparation Task B – Airworthiness Requirements
References

New references were added, including Part 27 and Part 29 which cover airworthiness requirements for normal and transport category helicopters and Part 39 which covers Airworthiness Directives (ADs). These three references are not in the paper FAR/AIM book, but can be found online. Part 43 covers preventative maintenance and there is also the FAA Risk Management Handbook 8083-2. Missing from both the PTS and the ACS list of task references are the aircraft POH/RFM (to cover Kinds of Operation Equipment List knowledge element) and AC-91-67 (cancelled but no good preplacement IMO) to explain how to deal with inoperative equipment and MELs.

Knowledge

New elements include Special Airworthiness Information Bulletins (SAIBs) like this SAIB for Robinson helicopter spindle bearing issues and an element on owner/operator versus PIC responsibilities for airworthiness. There is also elements on Kinds of Operation Equipment Lists (KOEL) and Special Airworthiness Certificate aircraft operating limitations (Light Sport, Experimental and Special Flight Permits).

Risk Management

The risk management section has only a single element, meaning you will have no choice but to cover this element on the checkride(learn what are the ACS minimum requirements in this General ACS Changes video). The element covers the risk management of finding inoperative equipment prior to flight (use the flowchart in AC-91-67).

AC 91-67 Inoperative Equipment Flowchart

Task C – Weather Information

Helicopter Private Pilot ACS Preflight Preparation Task C – Weather Information
References

The ACS removed the old cancelled weather ACs on Aviation Weather, Weather Services and the role of preflight. In their place was added the new Aviation Weather Handbook, AC 91-92 Pilot Guide to Preflight Briefing the usual Risk Management Handbook and Helicopter Flying Handbook. Also look at the PHAK Chapters 12 & 13.

Knowledge

Element K1 covers sources of weather – AWC, FSS, 1800-wx-brief (calling or website), ForeFlight etc. If you use ForeFlight, expect questions on where ForeFlight get it’s weather and is it valid for preflight planning (NOAA and yes – see AC 91-92).

If element K2 or K3 selected, a minimum of 3 sub elements must be covered. Those include some products not found in the PTS like SPECIs, PIREPs, CVA chart, GFA and Convective Outlook.

K3 new sub elements imply the ability to explain things such as temperature & heat exchange, details of microbursts, types of fog & how they form.

K4 requires an understanding of flight deck weather if you have it. So if you have ADS-B weather, know how it works, how to use it and when/how it updates.

Lastly it seems weather radar product is no longer listed.

Risk Management

Lots of new risk management specific elements, including circumstances that might cause diversion (weather, fuel, passenger issues, etc.) Also, have personal minimums already written down (day/night, local & XC). Under forecast hazards it includes known icing conditions – what is known icing conditions? There has been some confusion on that over the years, check out this HTV article on Known Icing Conditions.

Known Icing Conditions Article
Skills

Obtain an adequate weather briefing (I like calling 1800-Wx-Brief) but you could use the 1800 website, AWC, or ForeFlight, etc. Also analyze impact of at least 3 using actual weather or weather provided by the evaluator’s scenario. And like in the PTS, make a Go/No Go decision.

Task D – Cross-Country Flight Planning

Helicopter Private Pilot ACS Preflight Preparation Task D – Cross-Country Flight Planning
References

The ACS removed reference to the cancelled AC 61-84 (Role of Preflight Prep) and added the Helicopter Flying Handbook, Risk Management Handbook, AC 91-21-1 (Use of Portable Electronics on a/c) and Helicopter Route Charts. It also renamed renamed the old A/FD to the updated Chart Supplement. Check out PHAK Ch16 for navigation guidance.

Note

Computer generated flight plan is acceptable, but you must still know the process to go from true course to a compass heading, etc. We still recommend you start training with paper nav log & an E6B to fully understand where something like ForeFlight gets the numbers from.

Knowledge

Some of knowledge areas were probably covered in a PTS checkride, but now they are explicitly listed. Also notice use of EFB is a knowledge element, so if you use something like ForeFlight expect questions like “Are you allowed to use that in an aircraft? How do you know?” )Hint it is in the referenced AC 91-21-1. Also “How does ForeFlight get it’s nav log numbers?

Under altitude selection, the ACS wants you to consider helicopter autorotation performance in selecting a cruise altitude. For example it is best to be higher if over inhospitable terrain and/or with tail wind. The ACS also now talks of specifically knowing climb/descent rates & calculating TAS (rule of thumb + 2% per 1000’) as well as converting times to to UTC (Zulu time). There is also elements concerning how to file, activate and close a VFR flight plan. Some options include FSS radio, telephone (1800-wx-brief), text (via the 1800 website), & using a EFB like ForeFlight. Lastly, you can expect possible questions regarding an intercept procedures scenario.

Risk Management

You can expect scenario-based questions to assess your risk management in the 4 risk areas – Pilot, Aircraft, Environment and External pressures (PAVE) as well as the limitations of ATC services (radio & radar coverage at helicopter altitudes) and EFB risks (battery, overheat, etc.)

Skills

You still need to prepare and present an assigned cross-country using real-time weather and NOTAMs to first fuel stop. You will still need to prepare a nav log, but now also perform a risk analysis. You also still need to simulate filing VFR flight plan, but now also have to deal with a scenario causing change to the flight plan, requiring a fuel reserve recalculation (practice this).

Once again there is mention of EFB (if used) as an assessed element. And strangely no mention in the ACS of enroute checkpoints being ‘easily identifiable‘ – maybe that is just too obvious to be mentioned? Or maybe more emphasis now placed on GPS usage and position overlayed on an EFB map?

Task E – National Airspace System

Helicopter Private Pilot ACS Preflight Preparation Task E – National Airspace System
References

ACS still has Part 71 (Airspace Designations) which is in the in FAR/AIM book. But the ACS also has some new references: Part 93 (Special Air Traffic Rules – not in paper FAR/AIM), Helicopter Route Charts (find on ForeFlight or SkyVector) and the usual Helicopter Flying Handbook and Risk Management Handbook. Also check out the PHAK Chapter 15 on airspace. One reference this is missing from both PTS and ACS is the incredibly useful Aeronautical Chart Users’ Guide.

Knowledge

The ACS specifically calls for identification of chart symbols, which is why I highly recommend the FAA’s Aeronautical Chart Users’ Guide. It also wants you to know all about Special VFR – when you need it, how to get it, any limitations, etc.

Risk Management

For the ACS, with all it’s specific elements, this seems vague with no specifics strangely.

Skills

Very similar to the PTS, but with mention of SATR (Special Air Traffic Rules) & SFRA (Special Flight Rule Area) covered in Part 93.

Task F – Performance & Limitations

Helicopter Private Pilot ACS Preflight Preparation Task F – Performance & Limitations
References

From the PTS, the ACS removed the old (& cancelled) AC 61-84 (role of preflight), but also strangely removed AC 90-95 (Unanticipated Yaw ). AC 90-95 has not been cancelled and is a great resource for unanticipated yaw (LTE) and LTE is specifically mentioned in the Risk Management section, so I believe it was removed in error.

The ACS added the usual Helicopter Flying Handbook (check out chapters 6 & 7) and Risk Management Handbook. Also check out part of the PHAK Chapter 11 before it gets too airplane specific. Another good reference is the FAA’s Aircraft Weight & Balance Handbook.

If you are using a Robinson helicopter for your checkride, check out SN-37 Exceeding Operating Limits, SN-42 Unanticipated Yaw & SN-25 Carb Ice (when to pull extra 1.5, etc.) if applicable.

You can also check out the HTV article on the Height-Velocity Diagram.

Knowledge

The ACS added pilot technique, configuration and landing surface as elements to consider when thinking about aircraft performance. It also specifically mentions aerodynamics related to performance and limitations (think IGE/OGE, Retreating Blade Stall and LTE).

Risk Management

The new Risk Management section covers much of PTS content, but also talks about the difference between paper performance and actual performance (add a margin, do OGE hover power checks, etc.) It also mentions shifting, adding & removing weight – so practice talking through those sort of scenarios (unexpected extra weight etc.)

Skills

There are no real changes from the PTS here.

Task G – Operation of Systems

Helicopter Private Pilot ACS Preflight Preparation Task G – Operation of Systems
References

The ACS added the usual Helicopter Flying Handbook (check out chapters 3, 4 & 11) and Risk Management Handbook.

Also check out sections 3 (Emergency Procedures) and 7 (Systems) of your aircraft POH/RFM.

Knowledge

Much of the content is similar to the PTS, but the ACS added transmission & drive shafts (how does engine power get to main & tail rotors?). Element K2 requires the applicant to not only know the systems, but also be able to know the indications and procedures for managing system abnormalities or failures (in other words, know your EPs!)

Risk Management

This section really covers dealing with malfunctions and making good decisions (Land and Live) in scenario-based questions.

Skills

The skill element requires the applicant to operate at least 3 systems, which will usually be completed just by starting the helicopter (engine, fuel, oil, transmission, flight controls, etc.) As discussed in the General ACS Changes video, the ACS now disperses special emphasis items throughout ACS into the related tasks – so here we have a checklist usage element.

Task H – Human Factors

Helicopter Private Pilot ACS Preflight Preparation Task H – Human Factors

Task H was renamed from Aeromedical Factors to Human Factors, but much of the ACS content is similar to the PTS.

References

The ACS added the usual Helicopter Flying Handbook (check out chapter 13) and Risk Management Handbook. The PHAK has most of this covered in Chapter 2 and Chapter 17.

Knowledge

Much of the content is similar to the PTS, but with the addition of nutrition, hypothermia & optical illusions. For all the sub elements of K1, make sure you know the causes, symptoms, effects & corrective actions. The ACS also specifically added an element on the regulations regarding alcohol & drugs. And K4 is a dedicated element covering ADM/CRM/SRM (check out the PHAK Chapter 2, HFH Chapter 13 and much of the Risk Management Handbook).

Risk Management

The Risk Management section covers a few areas, including hazardous attitude & antidotes (use IM AIR memory aid) as well as distractions and situational awareness (previous PTS special emphasis areas). A new element not used in the PTS is confirmation and expectation bias – check out the Risk Management Handbook for more information on those terms.

Skills

In a scenario given by the evaluator (or the checkride flight), the applicant will make a self assessment – use the IMSAFE memory aid and have personal minimums already written down!
