deniasol Posted October 9, 2012 Report Posted October 9, 2012 Hi,I'm new to the DC3 so the answer to my problem may very well be buried somewhere in the manual. I'm trying out the DC3 at El Alto airport in La Paz to test the limits of this old lady. Three times after take-off, I've got a red warning message on the bottom of the screen which says something to the effect that the engines are about to fail and that I needed to reduce power immediately. I was flying well within limits and neither exceeded the CHT nor the oil temperature. Any idea why this is happening?Many thanks.Enzio
Goran_M Posted October 9, 2012 Report Posted October 9, 2012 It's possible to blow an engine even if the oil and engine temps are within limits. An overly high Manifold Pressure and/or Engine RPM that is sustained for too long can cause engine damage (Try revving your cars engine to an RPM in the red zone and watch how quickly the engine dies while all temps stay within normal limits)Make sure your Manifold Pressure is below the red zone.

At 13300 ft airport elevation a plane eats up the runway pretty fast and when all your concentration is on the airspeed indicator I may have neglected engine parameters for a second. I'll try to reproduce the situation and I'll upload a screenshot next time this happens.Regards,Enzio
Goran_M Posted October 10, 2012 Report Posted October 10, 2012 Don't be afraid to max the throttles for a takeoff. Max throttle is allowable for many aircraft for a short period. Usually 30 seconds to a minute.Once takeoff is achieved, that's the time to reduce to a reasonable climb power setting.
C47 Posted November 19, 2012 Report Posted November 19, 2012 I hate this in flight warning, Is there any way to avoid this kind of warning ( I have already disabled the warnings in the preferences)."Caution! Engines are about to fail. Reduce power immediately."
Cameron Posted November 19, 2012 Report Posted November 19, 2012 Yes, by reducing your power! In all seriousness though, no, there is no way to avoid it but to fly it properly.
Vinny003 Posted March 3, 2014 Report Posted March 3, 2014 Hi, deniasol!At the elevation of 13,300 feet MSL, the engines won't have as much power as it would at a lower altitude. I normally takeoff at 40 to 42 in MP. Hope this helps! Cheers, Vincent
eMko Posted March 3, 2014 Report Posted March 3, 2014 Yesterday I was trying to overfly the Austrian Alps and I was not able to even climb to more than FL90 without frying the engines. Plane weight was around 25.300 lbs, QNH 1013 and 15°C at 0 MSL. Is it normal or I did some error? Like improper mixture settings?

Vinny003 Posted March 3, 2014 Report Posted March 3, 2014 (edited) Hi, Cameron!Okay! Got it! Thanks! I always use the search feature before I resurrect old threads. Cheers, Vincent Edited March 3, 2014 by Vinny003
Vinny003 Posted March 5, 2014 Report Posted March 5, 2014 Hi, guys!I used the search function but I cannot seem to find what I'm looking for but I got question for you, how long does it take for the engines to be damaged if running at full throttle, even at high altitudes the engines will be damaged when running at full throttle? Thanks! Cheers, Vincent
Goran_M Posted March 5, 2014 Report Posted March 5, 2014 Assume they will be damaged within seconds. The engines should NEVER be at a setting where it flashes the warning up. That's telling you that engine failure is imminent and you must reduce power immediately. This varies with environmental conditions.
Vinny003 Posted March 5, 2014 Report Posted March 5, 2014 Hi, Goran!Really? That fast? What is the ideal throttle setting for takeoff? Thanks! Cheers, Vincent
Goran_M Posted March 5, 2014 Report Posted March 5, 2014 That depends on too many factors. Altitude. Pressure Altitude. Temperature. Winds.Always check the charts.
