Gear partially deployed. What to do? - Psycho762 - 16-11-2005
Howdie,
I wondered what are the parameters to safely land when you encounter this failure. I made a belly landing and kissed the ground at 125
ft/min and still crashed. Probably my speed was to high because of a steep descent. Tried to find a real life abnormal checklist but
couldn't find one. Since all landing gears were not deployed i couldn't copy the airblue stunt (doing a wheely...
) and i don't have a manual lever to pump the gear down, so what to do beside declaring a mayday, doing a low flyby for the virtual ATC personnel to check
the state of the gear, aiming for a low speed with full flaps and kissing the ground? I read in this forum to bounce te plane (is this a yoke)
and more important is this programmed in FSP to solve the gear problem?. When i try a belly landing what are the programmed
parameters to succeed (max vref + 5, less then 500ft/min?)
Please enlighten me,
Psycho762 aka KLM762

Not sure if i understand it right but with a partially deployed gear you should try to land quite 'hard' to let the gear lock in place...
Sometimes you have to repeat this process till it deploys
Re: Gear partially deployed. What to do? - Jetflyer - 16-11-2005
It won't register a crash at -125ft/min. You must have had the failure which requires a belly landing, then you have to land at about -
50ft/min to do it safely. This may sound like the "easy way out" but you could just disable crash detection because it is very unrealistic on
FS2004 and FSPassegners. I have it disabled due to terrain making my plane jump up and down and crash on taxiways. Fat chance I'll
be dumb enough to land a 8 hour flight in LAX to have my plane bounce in the air on taxiing and crash. With crash detection off it is no
less realistic than with it on.

1/ bounce the plane to get the gear down
2/ pray the gear went down
3/ repeat steps 1 & 2 until :
a/ the gear is down and you land normally
b/ you fathom out how to get the bird down in one piece w/out the gear.
c/ you run out of gas........
Re: Gear partially deployed. What to do? - Psycho762 - 16-11-2005
Okay, so i have to use the TPBP protocol (Think, Pray, Bounce and Pray again) and grease the plane at 50ft/min on the tarmac (hoping
the scenery builder has flattened the run en taxiways? Still there remains the question if bouncing is programmed (in FSP) to let the
gear down.
Anyone know of reallife procedures? Never heard of bouncing planes.

Depends, if the gear didn't deploy at all, you have to make a belly landing and do it soft. If it was partially deployed you have to land hard
so that maybe the rest of the gear deploys also
Re: Gear partially deployed. What to do? - Ryanamur - 16-11-2005
Sure, it's been a while but it would be something like this for one of the mains:
1- fly the plane
2-declare an emergency
3- attemp to lower the gear manually (do not attemp to raise the gear and lower it again... if its and hydraulic leak, you'll loose more fluid and will lower your chances of successfully lowering the gear manually)
4- do a fly by the tower to get feedback on landing gear
5- repeat approach (you might want to dump or burn some fuel first)
6- line up with the runway but plan to land with most to the runway on the bad gear side (ie good gear closer to the grass)
6a- overshoot if not happy with setup
7- Touch down on the good gear and prevent the bad gear from touching as long as possible
7a- Shutdown engine to prevent fire, limit thrust and, FOD
8- Apply no brake (or minimal brakes to ensure safety)
9- Anticipate wing drop on bad gear side
10- Anticipate to apply full rudder on good gear side (you might also have to apply brakes on good gear side... that's OK)
11- DO NOT TAXI THE PLANE OFF THE RUNWAY UNTIL THE GEAR HAS BEEN PINED!
The only difference if it's the nose gear is that you would land in the center and you wouldn't have to worry to much about the rudder.

Plus of course you would be getting a better look at the runway than you like.

If you are religious then pray. If you are not religious then virtually pray

Off topic--Whats real and what is virtual? There are times i don't know the difference. Certainly not in front of my pc on an windy final
approach. For me praying is in its essence virtual, but it works for millions of (desperate and not so deperate) people. A Nice way to deal
with the uncertainties of life (like an unwilling gear). Part of the fun of virtual flying is forgetting real life and for a moment forgetting it's just
a game. Of course i learned a lot over the years, which is fun for me too. Do have meters of info on aviation on the shelf now. Next year i
gonna take real flying lessons overhere at Lelystad Netherlands. Hope i'm than able to make the distinction between real en virtual...
Anyway, they charge real money (oops). Gonna cost me about 11000 euro's. Even a class 2 medical costs 270 euro. Friendly thieves...
On Topic-- Did a few flights with failure nr 19 selected. Managed to do belly landings but was not able to bounce the 737. Took me 1100
meters to stop the plane with a vref of 140 (no, didnt dump all the fuel)in gusty conditions. For the sake of my virtual career and the health
of my virtual passengers next time it's divert to an airport with long runways and ILS capability (easy stable approach (yes i'm lazy), dump
some fuel above a virtual lake en down with the belly. Company not happy but what the heck, my boss is only a virtual boss.

I don't assume that reallife linepilots do a belly or bouncing landing with the gears up every year

Real is is simming with Vatsim controllers
Re: Gear partially deployed. What to do? - bloha - 16-11-2005
It happened to me one time. The nose gear didn't extend fully if I remember correctly (it was late at night
).After declaring an emergency etc. I tried to retract the gear which did work. My thought at the time was "let's go for the sparks"!
I slowed down with full flaps (PDMG 737, 40% flaps) on approach, while trying to maintain level flight (I wan't to scim the runway).
To my big surprise, it worked! The passengers screamed madly and left the plane in a hurry. I even got about +1400 points (partially for
crashing on eta
.Let me see if I can get the print screen in the message.

I think I'm going to raise my failure rate percentage

Nice one Hans! Landed in the grass on prupose? Passengers will sew you for ruining their shoes in the dirt.
Most belly landings are on the runway (with the risk of fire -friction-). Landing on soft terrain has the risk of flipping over.

Re: Gear partially deployed. What to do? - bloha - 18-11-2005
Thanks Psycho!
no, I had a lot of sidewind so I didn't line up straight enough. Once you hit the deck.....there's no such thing as steering
.That's why I ended up beside the runway by the time I stopped.
Sure liked the video, thanks for the link (I'll see if I can do better than that guy
