Over-pitching



(Updated on 28th March 2021)

What Is Over-pitching?

Over-pitching

Overpitching occurs when you demand too much power from the engine and a drop in Rotor RPM (RRPM) occurs. When you keep raising the collective lever without any consideration for power limitations; you are increasing the pitch angle of the main rotor blades. As the pitch angle is increased, drag is also increased. To overcome the drag, more fuel must be added to the engine to increase power. This is normally done by a correlator or a governor or both.

If the collective lever is raised further, at some point the engine will be at full throttle. Any further attempt to raise the collective will result in a reduction of RRPM as the engine has no spare capacity to overcome the drag on the blades. This is a very dangerous situation. “Overpitching”.

As the RRPM decays, the main rotor blades will cone more and the coning combined with the reduction in RRPM and subsequent loss of lift (due to reduced airflow over the blades) will cause the helicopter to descend.

A pilot’s automatic (but INCORRECT) reaction to stop the descent is to raise the collective. Obviously this will increase the pitch angle and cause a further reduction in RRPM and a faster rate of descent.

Recovery From Over-pitching

The recovery from over pitching is not instinctive and relies on good training habits. When the low RPM warning horn/light comes on during normal flight, you must react immediately.

  1. Lower the collective to reduce the pitch angle and thereby reduce the drag on the main rotor blades.
  2. Simultaneously open the throttle to help recover the RPM.

Combining the collective movement with the throttle movement will recover the RRPM in a timely fashion.

EASA Type Ratings For Helicopter Pilots



(Updated on 28th March 2021)

Why Get a Type Rating?

Type RatingSo you have a PPL(H) and you want to try something different. For most pilots, getting another type on their license is one of the first things they will do. Having probably completed their training on a two seat helicopter, they now want to carry more passengers and luggage. Larger helicopters will probably have a faster cruise speed and so traveling time is reduced. But what is involved in getting a type rating?

If you are getting your first Robinson R22 or Robinson R44 type rating, then you will have to do a minimum of 5 hours flying during your type rating course. Assuming you already hold a type rating on another type of helicopter then you will still need to do a minimum of 5 hours flying on your type rating course unless it is of a similar type.

Your first piston engine type rating will require you to fly a minimum of 5 hours during the course. If your type rating has expired by 3 years (or longer) and you need to renew it, the amount of training will depend on your experience, how long the rating has lapsed and your aptitude.

If a type rating has lapsed, the pilot shall take refresher training at an Approved Training Organisation (ATO). The amount of refresher training needed will be determined on a case-by-case basis by the ATO, taking into account the following factors:

  1. The experience of the applicant. To determine this, the Head of Training will examine the pilot’s logbook.
  2. The complexity of the aircraft.
  3. The amount of time lapsed since the expiry of the validity period of the rating.

The amount of training needed to reach the desired level of proficiency will increase with the time lapsed. In some cases, after evaluating the pilot, and when the time lapsed is very limited (less than 3 months), the training organisation may even determine that no further refresher training is necessary. When determining the needs of the pilot, the following items can be taken into consideration:

  1. Expiry shorter than 3 months: No supplementary requirements.
  2. Expiry longer than 3 months but shorter than 1 year: A minimum of 2 training sessions.
  3. Expiry longer than 1 year but shorter than 3 years: A minimum of 3 training sessions in which the most important malfunctions in the available systems are covered.
  4. Expiry longer than 3 years: The pilot should again undergo the training required for the initial issue of the rating or for the training required for the ‘additional type issue’, according to other valid ratings held.

Once the training organisation has determined the needs of the pilot, it will develop an individual training programme that will be based on the initial training for the issue of the rating and focus on the aspects where the pilot has shown the greatest needs.

Approved Training Organizations (ATO)

All training for type ratings must be undertaken at a training school approved for type rating training. These schools are called Approved Training Organisations (ATO).

You can check with your country’s Authority to find out which training organisations can do the specific type rating courses.

How Long?

If you are doing a type rating course that only requires 5 hours of flying, you can expect to spend the first day in the classroom and learning all about the systems of the helicopter. This will normally end with a technical written examination on the specific helicopter type.

The following two days will normally be spent doing the flying part of the course. The flying does not have to be done right away. You can do this at your convenience but if you have the time and the money, I would advise doing it all together.

When your flying training is complete, your instructor will sign a course completion certificate and an application can be made for you to be tested by an examiner.

The Flight Test

The flight test will normally take between 45 minutes and 1 hour. It is a test of your general handling. There is no navigation as such but you will be required to fly away from the airfield and return to it and do all the radiotelephony. The flight test tolerances are the same as the PPL skills test. You will have to demonstrate proficiency in all of the general handling manoeuvres and complete some simulated IFR manoeuvres.

Make sure you know the emergency procedures off by heart as you will definitely be asked most (if not all) of them.

Revalidation

To keep your rating current, you must do a License Proficiency Check (LPC) each year. This can be completed up to 90 days before it is due to expire and if you pass it, it will be valid for another year after it is due to expire. You must have completed at least 2 hours flying (dual or solo) in the previous 12 months before doing the LPC.

If the rating has expired then you will have to renew the rating (see above).

How to Progress Your Career



(Updated on 26th March 2021)

Helicopter Preflight

Introduction

Almost invariably I get asked the same questions on every course that I teach. When I run a commercial course, the CPL students will at some stage, almost always ask me “What do I have to do to get ahead in the helicopter industry?” or words to that effect.

In my opinion this is an easy question to answer and actually pretty easy to achieve if you are prepared to work hard.

What You Need to Do

So what do you need to do to progress your career as a helicopter pilot?

Well you actually do not have to do very much. You only need to do what you were trained to do. I will provide a list below of what I think is important. I would expect all helicopter pilots to be able to do the following.

The list is not conclusive and I am sure there are plenty of other items that could be added to it. But if you can manage to consistently do the things on the list, then that is all you need to do. Without doing anything else you will get noticed. People appreciate hard work. You will get noticed for being consistent and for being a hard worker. All employers love hard workers.


Putting it into Practice

I tell my students that they should be striving to achieve everything on the list but that they can do more. They should aim to be the best pilots that they can possibly be. Perfection is unobtainable but that is what you should strive for. You should aim to be better than all of the other employees in the company.

Being better does not mean only flying better. Of course the flying skills are important but there is so much more to it than that. Your expert knowledge will also set you apart. It never ceases to amaze me how many CPL pilots coming through to do the Flight Instructor (FI) course, who have big gaps in their theoretical knowledge. Gaps in subjects like Air Law, Meteorology and Principle of Flight are common because they have not looked at a book since they obtained their CPL.

If you want to be different, refresh your knowledge. Become an expert in your field. Let people come to you for the answers because they know that you have the knowledge. You have the answers. Of course you will never be capable of knowing it all. No one can achieve that. But you can know more than anyone else if you put your mind to it.

Conclusion

Therefore what you need to do to progress in the helicopter industry is be the best pilot that you can be. Learn as much as you can about technical matters, relevant legislation, meteorology etc. And generally work as hard as you can and help out as much as you can – all while being a nice person to work with.

Do not try to step on other peoples shoulders to make it up the ladder. This will come back to haunt you in years to come. Just by keeping your head down and helping others while doing your job to the best of your ability is guaranteed to get you noticed by the right people.

Let me know if you think this was useful by leaving a comment below. Thank you.

EASA Theoretical Knowledge Examinations



(Updated on 26th March 2021)

EASA Helicopter Exams

Introduction

I am starting to get a lot of enquiries from both students and pilots in relation to what is required for the theoretical knowledge examinations for EASA helicopter licenses. This post will provide you with the new list of exams. These exams have already been launched in the UK and will take effect in Ireland from April 7th 2014. Anyone already training in Ireland under the old JAR system will have one year to complete their training from that date otherwise they will have to meet the requirements of the EASA system. Anyone in Ireland who has commenced their training after April 7th 2013 will already be training under the new EASA system.
