Quite some clouds in the mountain passes again. Add to this a slightly off DR'ing, made me miss the lowpoint of the pass and get a little confused about where to look for the airport. Only saw it after passing, but that was perfect point for the base leg anyway.
My landings are still not nice... I heard some campesinos mutter something about a Gringo loco...
One strange incident.
Halfway into the flight I lost a lot of airspeed; dropped from 125 KIAS to below 100 KIAS over a few minutes. Engine power (MP/RPM) stayed the same. Had to increase power to compensate.
Carburetor icing? Does this really happen in fs? I did activate carb heat for 30 sec, without effect. Pitot heat had no effect either.
Structural icing? (???) I did fly in clouds then.
Ambient pressure/temparature change? The VSI did big jumps on this flight.
Robert, that sounds like a good possibility. Every once in a while, FS weather will throw in extremely, and unrealistically, high or low air pressure. Makes for an extra challenge to add a little spice to humdrum flights.
Freak weather change then.
It could not have been structural icing in any way as temperature was too high. About 20 C at 7000 ft upon take-off.
Thanks.
Once when flying over the Andes during another South American event we had a couple of years ago, my seemingly sturdy Martin Maryland bomber suddenly lost airspeed & power. I could not recover, went into a stall and spun in and crashed. The weather had been good and I was just cruising along on otto. It was not a systems failure of any kind. Bermuda triangle effect? Aliens?
It was the oddest thing and I haven't encountered it since (knocks on wood).
Decent weather for the flight through the mountains, with nice views of the pyramid of Nevado Tolima and Nevado del Huila.
Pitalito though was quite socked in... saw it after almost having passed, and got a little disoriented (to say the least) circling for the landing.
Quite a few spectators had showed up. Seems somebody from Manizales had told them that the landings of the Gringo loco are a lot of fun to watch. Welcomed me laughing, big pats on the back and a bottle of aguardiente. Needed that. Don't remember anything more after that.
Btw, had power loss again in flight. Outside temperature was -2 °C, carb air temperature 0 °C.
Turned on the anticer and defrost switches (in fact every switch available); that seemed (?) to solve the issue. I guess I should have ****...
Ok. Antiicer and defrost was not the solution. Had power loss again, just the moment OAT and carb temperature reached 0 C.
Didn't have a lot of time to investigate, as engine 1 stopped.
That was due to fuel for both engines being somehow drawn from right tank; and this tank running dry.
At the same time high point of the flight was looming ahead. Struggled to maintain altitude and just scraped over the pass. From there it was just downhill, and luckily good visibility for the landing.
That landing was even halfway decent...
Robert, I did turn carb heat on when I encountered power loss, and that seemed to improve the situation after a few minutes. Had tried it before, but maybe I didn't wait long enough. Thanks.

Pretty good visibility in Quito. Unfortunately the nice volcanoes around there all in clouds. Riobamba fogged in.
