Re: Shock Cooling a myth?

I used to be unsure about this until 2 yrs ago. In 8 years of flying our Navajo we had never had a cracked cylinder. 2years ago #2 and#3 cylinders on our right engine (our hotter running engine) came up with low compression due to cracks running from the intake valves towards the top plugs. I decide...

Re: Which heading for an emergency letdown

Back during WW II they taught that if all you had left was your mag compass and the ball on your T&B you should descend on a 180 heading. Then you reduced power and used rudder to stay on that 180 heading. There would be minimal compass lag and an increasing heading meant you were in a right turn an...

Re: Hand flying

At NWA back in the 90s we were encouraged to keep up our hand flying proficiency, but a lot of guys would put on the AP at 200 feet and not turn it back off till 200' at the destination. I loved hand flying the A320. With that auto trim it was so easy. My previous Air Force experience in the F111D h...

Lycoming overhaul facility in Eastern Canada

I might be needing to overhaul a TIO 540 A2B in the near future. Any recommendations on any shops that do excellent work at a reasonable price? Alternatively a lead on outfits that sell used low to midtime engines of this type.

I have a 1968 PA31-310 Navajo with an aftermarket AC unit that uses what I believe is about a 40 amp motor to drive the compressor. The battery is a 17amp hr wet Gill that's 2.8 yrs old. The alternators are 50 amp. Last friday it was so hot I had to run the AC continuously at cruise altitude of 6500...

Navigation fees

I am thinking of flying my Navajo up to Canada, and I will definitely be flying some Part135 commercial charters to Canada for my new employer also in Navajos. I seem to remember from my airline days that Canada privatized its ATC and there are fees to be paid if you file and fly IFR. If one of you ...

Re: How Beta can bite you

This doesn't just apply to props. On the DC9, reverse thrust blanks out the rudder. You have to be very careful using moderate to high reverse thrust on a slippery runway with a crosswind. When I was a green FO landing in DTW one winter evening with the conditions just stated, I damned near went off...

Re: Is there really a pilot shortage?

Re: Gulfstream Autopilot Malfunction

If this ever happens to you, and you're worried about being able to keep the nose down, the best technique is to roll into a 40 to 50 degree bank while you sort out the issue and pull the circuit breaker.

Re: Delaying Engine Anti-ice can cause trouble

We had a similar incident many years ago at NWA. One of our DC9s was going into Houston Texas, and ice was the last thing on their minds. Anyhow, they either weren't paying attention or ignored company policy and FOM guidance to turn on engine anti ice with temps 6°C or below in visible moisture. Sh...

Re: PA31Main gear oleo strut pressure

i finally got it done. The key was a suggestion I got on another forum. My source told me to figure the area for the top of my strut piston by multiplying the radius squared times Pi (3.14.) My strut is 2.75" in diameter so radius is 1.375". Area is 1.375"X1.375"X3.14=5.94 square inches. Divide that...

PA31Main gear oleo strut pressure

My service manual and POH both say the strut should have 3.25 " of piston extension under a normal static load. One of mine is about 1 1/2" low. There is no mention of the nitrogen/air pressure with weight on the gear. I have a nitrogen tank that can put out 1500PSI, but I don't want to blow up anyt...

Re: Does aircraft weather radar detect traffic?

The radars on the A320 and the DC9 do a great job of picking up aircraft. You need to use high gain and proper tilt. Planes with large turbofan engines like the A320 and larger are easy to pick up especially from rear or front aspects.

Re: Spiral dive

Remember, it's very important to level the wings before pulling. If you pull up while rolling, you'll be subjecting the wings to an asymetrical load. Depending on your roll rate and pull, one wing could be subjected to twice the G load that you feel.
