OSH observation

[Dan Luke]

Departing OSH Wednesday morning, the departure wait for light GA peons got
pretty long. I was interested to hear the ever-more-urgent pleas from a
Cirrus flight of four to speed things up because their engines were
over-heating as they sat idling in line.

Didn't hear anything like that from any of the dozens of other aircraft
waiting to go. It was about 8 in the morning; not hot yet.

Can't imagine why they'd have an overheat condition. Hell, just shut
down in line and monitor ground/twr with a handheld then..

This makes me wonder if they were using that as an excuse to get
preferential treatment. I've never heard of Cirri overheating while idling.

You need to be able to move every couple of minutes....

Re-starting an over heated, fuel injected airplane engine is far from a
sure-thing proposition.

The Cirrus demo guys have a tendency to get impatient pretty quick.
We've had on and off problems for the last several years out on the
flight line.

Heck, restarting a hot fuel injected airplane engine, whether overheated or
not, is far from a sure-thing proposition. :)

Maybe those others don't have engine monitors to make the worsening
situation obvious. A tightly-cowled big-bore engine will be stressed
if left to idle too long. First hand experience: I tried not to whine
about it on air beyond offering to depart VFR, but a 45-minute
take-off wait at KTEB last week made my IO-540s very unhappy.

Tightly cowled? IO-540s? Sounds like a Duke?

The Duke uses a TSIO 541 engine.

Of course. How silly of me - an Aerostar then??

OT: Is the 541 engine on the P-Navajo also? IIRC that was a geared
425hp mill?

I had the same thing happen to me in a 1956 Bonanza at OSH.
