Re: Proper way to turn off the engine?

Almost every single GA piston that I'm aware of is shut down by mixture lever. If you kill the magnetos, you might cause some severe backfiring. Severe enough to even cause occasional damage on some exhaust systems. That is because the fuel/air mixture sustaining combustion supplied by the fuel mete...

Re: A2A Simulations - Mini Holiday update

A very nice cabin there! And I like that you model these older models too - when I worked with GA aircraft, an average age of the planes was almost twice the age of mine! (Though I'm catching up every year..) Aviation is a fun business in a way - I once checked a technical logbook of a certain PA-28...

Re: Dream Sheet Item - Periodic Inspections

Actually, this relates to something that I'd like to request. That is, I think there should be an option that requires you to point out the items to be inspected. As it is now, if I accidentally bring up the maintenance hangar, the battery gets charged all the sudden and all kinds of stuff are point...

Re: How to choose a printer.

Thanks for the reply but it looks like the R3000 is wide format and doesn't suit my needs. I need color primarily for documents, not photographs. The protocols I print out are color coded by level of care and various colored texts to draw attention to drug dosages and contraindications. I suppose I...

Re: How to choose a printer.

Hi, If your print quantities are "moderate", I would consider any inexpensive, but reasonably reviewed color laser - for typical office papers their output is a way better than that of inkjets. I use a cheapish Dell color laser for most stuff, the quality is very reasonable and beats usual office co...

Re: Alternator Voltage

I might add that it is implied in the ACU maintenance practices chapter that anything above 29 V is considered too much at least when testing it after work done on it (even if the voltage is not enough to trip the CB): "If the voltmeter shows more than 29 volts, immediately set the ALT MASTER switch...

Re: Alternator Voltage

According to 172R/S AMM, the Alternator Control Unit "... controls the alternator field circuit to supply a main bus voltage of approximately 28.5 volts ." The low voltage annunciation is provided whenever the bus voltage is "less than 24.5 +0.35 or -0.35 volts", and over-voltage protection "...dise...

Re: external power

Actually, at least the later 172's do have an external power receptacle for 28VDC input. I've never used that, nor have I ever heard anyone to have used it, for any purpose however... :) - Esa (Edit: Though I've actually been using it in C208s for G1000 updates, turbine washes etc. Not sure about it...

Re: The Ball, the Heater, the flare, taxiing, the usual.

Hi all, I've only got only about 20+ hours in this C172 sim, and less than a quarter of that in real Cessnas (none of which in 172 model). So I would not consider any of my opinions to be "facts" compared to many other posters around here. :) About the flight dynamics - I only got a very imprecise t...

Re: 100 hour inspection

Hi all, especially Americans/Canadians - Regarding the topic, and out of curiosity, I'm interested to ask how the inspections to GA aircraft are required to be performed by authority in North America these days? Specifically, is the compliance with relevant SB's and specific AMM Chapter 4 & 5 (etc.)...

Re: Starting F.I. Lycoming engines with mixture in cut off..

I'd say the main reason is the Bendix RSA fuel injection system's fuel/air control unit. It basically measures the air intake of the engine by comparing the differential between the intake total pressure (measured by four pitot-tube-like things within the unit) and the static pressure at the venturi...

Re: Flight Model of the C172

Lupakirjan saamisen jälkeen huomasin, että määrätyt jutut on simussa liian helppoja ja vähän väärin, ja siksi kiinnostaa, että miten näissä uudemmissa tuo puoli on hoidettu. Toi on kyllä tuttu fiilis; oon ite myös alkanu uskomaan, että ehkä menee osit...

Re: OUT !!!

Quickly tested with about an hour spin going through the systems and handling. Seems very nice indeed! So far only a few minor things that I'd wish that get some attention in the future, overall this is a very complete, nicely polished and well flying package, mostly up to, and many ways even beyond...

Re: Firing order

About the only thing different with all various 4-stroke engines when speaking of boxers, V-engines, inlines and so on, is the piston configuration. Actually that's the small thing that separates the boxer engine from 180° V-engine, though the term V-engine would be somewhat incorrect here. anyw...
