As I understand it, the FAA requires that ONLY the time spent flying on instruments in actual IMC is to be recorded in your logbook as instrument time.

Does everyone adhere to this rule as closely as possible? I find it hard to believe that someone flying on a cross country instrument flight plan, that takes you in and out of IMC, will actually record (even by a rough estimate) the time they were between layers or "on top" as VFR time, and only the time they were actually "in the soup", as instrument time.

Am I wrong? Do you do your best to keep the two seperate as a general rule?

I'd hate to be the only guy in the sky trying to keep all that straight if no one else is. I can just see me with a stopwatch: ...... ok, I was in that cloud for 16 seconds, been in the sun for 39 seconds now, hmmm ..... looks like I might only be 965 feet from that cloud .....ooops, here comes another one ........ where's that #@%#* approach plate ....etc.

Thanks for any insight.

If you see it log it, if your in it double it. Just kidding(LOL).
Thats the same rule I use for logging multi time.
 
If I'm in the clouds, I guess, a very very conservative guess.

You can't waste time timing how long you're in the clouds. If you just penetrate and cloud and pop out in 5 seconds, I don't count that at all.

If I'm in the soup, I'm too busy concentrating on the instruments to sit and time it with a stop watch.

Not exactly. There is no mention of IMC in § 61.51(g). Instrument flight conditions does not always mean IMC.

You could log actual in perfectly clear weather.

Its night, you're over the desert, there is zero horizon, there is no way to use outside references to determine the attitude, altitude, etc., of the aircraft. You can log actual b/c you're flying by reference to instruments only.

And IMC does not always mean actual instrument flight conditions.
 
If I need to fly the plane by instruments to keep it up right and on course by reference to instruments than i would log it. Even if I am above an overcast layer.

I think you would get yourself into trouble on an airline interview if you responded this way when they were asking you about your logbook.

In order to log actual instrument time. It is the time when controlled the aircraft solely by refrence to the flight instruments in weather less than VFR as defined in the type of airspace that you are in.

FWIW crzepilot's definition pretty much tracks FAA doctrine

==============================
"Actual" instrument flight conditions occur when some outside conditions make it necessary for the pilot to use the aircraft instruments in order to maintain adequate control over the aircraft.
-- 1984 FAA Legal opinion
==============================

This is from the famous "moonless night" opinion saying that a pilot with no instrument rating may log actual instrument time in VMC.

(leaving open the question of what it was about the nature of the overcast that required the use of instruments to remain upright.)

I'd be very, very careful with that one.

I would love to see how they take that on an airline interview. You are in VFR weather logging actual instrument time?
 
I always wonder about those "but will the airline like it that you followed the rules?" comments. Considering all of the violations that FAA inspectors tend to find in some of these operations, I guess it's not that surprising.

So they're going to look at my logbook date, go to a weather source, look up the weather for that day, verify it with my route of flight and then ask me why I logged instrument time?

To both pilotmyf and siucavflight :

Logging actual instrument conditions at night, with no horizon or method of telling you what the plane is doing is 100% legal. There is no question about it and I've asked many senior flight instructors and 4 different examiners and they've all told me .. if its night, you can't see the horizon and you are 100% on the instruments to determine the status of the plane, you can log it as actual.

Ask on ProPilot's FAR forum. I'm sure you'll get the same answer from "Doc"

I guess then I should go back and record about 400 hours of actual instrument time in my logbook. Thanks.

In fact, the legality of logging actual on a moonless night etc. stems from a legal opinion issued by the FAA Assistant Chief Counsel:

FAA Legal opinion, NOTE: FAR 61.51(c)(4) is now codified in 61.51(g), the concepts cited remain valid. the opinion has been edited for brevity:

"November 7 1984



Mr. Joseph P. Carr



Dear Mr. Carr:

This is in response to your letter asking questions about instrument flight time.



First, you ask for an interpretation of Section 61.51(c)(4) of the Federal Aviation Regulations (FAR) regarding the logging of instrument flight time. You ask whether, for instance, a flight over the ocean on a moonless night without a discernible horizon could be logged as actual instrument flight time.



Second, you ask for an interpretation of Section 61.57(e)(2) of the FAR, noting that Advisory Circular 61-65A, Certification: Pilots and Flight Instructors, seems to contain advice contrary to your understanding of the rule.



As you know, Section 61.51(c)(4) provides rules for the logging of instrument flight time which may be used to meet the requirements of a certificate or rating, or to meet the recent flight experience requirements of Part 61. That section provides in part, that a pilot may log as instrument flight time only that time during which he or she operates the aircraft solely by reference to instruments, under actual (instrument meteorological conditions (imc)) or simulated instrument flight conditions. "Simulated" instrument conditions occur when the pilot's vision outside of the aircraft is intentionally restricted, such as by a hood or goggles. "Actual" instrument flight conditions occur when some outside conditions make it necessary for the pilot to use the aircraft instruments in order to maintain adequate control over the aircraft. Typically, these conditions involve adverse weather conditions.



To answer your first question, actual instrument conditions may occur in the case you described a moonless night over the ocean with no discernible horizon, if use of the instruments is necessary to maintain adequate control over the aircraft. The determination as to whether flight by reference to instruments is necessary is somewhat subjective and based in part on the sound judgment of the pilot. Note that, under Section 61.51(b)(3), the pilot must log the conditions of the flight. The log should include the reasons for determining that the flight was under actual instrument conditions in case the pilot later would be called on to prove that the actual instrument flight time logged was legitimate.



[Answer to second question deleted due to not being pertinent to this discussion -- Doc]

Sincerely,

/s/

John H. Cassady

Assistant Chief counsel

Regulations and Enforcement Division"
 
Answers my question. I now have 476.4 actual instrument hours instead ofthe 82.3 that I used to have.


I am so glad that one mans opinion allowed me to do this.

You better make sure the chief pilot at your next job feels the same way about logging actual in severe clear. A guy flying in AZ with 100 actual and 1000 total time might send some red flags. All it takes is a little doubt about your logbook from an employer to get your butt eliminated from a job opprotunity. Last time I checked, examiners aren't big employers. PLAY THE GAME!!!!!!!, stay conservativeon your entries.

Yeah! Better makes sure that the chief pilot at you next job agrees with the FAA!

If not, you never know where else the operation disagrees with the FAA. Maybe maintenance? Maybe rule of flight? Maybe the weather conditions that are permissible. Maybe...
