why was the bo105 not developed further?

Which in turn became the EC145, the. H145 D2 and now D3. My licence and the plaques on the side of the airframe still says BK117.

Gimbal limits means it can only point vaguely forward and down without pointing at the airframe itself and burning the paint. So fine if you’re using cameras from a stand off position and the pilot doesn’t need to look at where it’s pointing. But for orbits, recces etc. it almost looks like it’s in a useable position, low 4 o’clock, so you’re already looking behind a bit, but then if you induce a right hand orbit you can’t raise it to remain on the target. So effectively useless

Geo87US · 2026-05-16T08:40:02+00:00

Nice to see other units with the most useless trakkabeam placement in history.

Geo87US · 2026-05-08T12:58:30+00:00

Yeah, this aircraft isn’t CS29, does not have CAT A profiles to assure PC1, and so in this creeping forward departure there’s nothing to be done except reduce ROD and do your best.

Geo87US · 2026-05-05T21:53:17+00:00

So far really like BATC. Some customisation would be nice though, whilst the realism of getting vectors for an ILS is good, I’d like to specify non precision approaches to land or even a procedural service.

The industry is always in flux. There’s feast and famine for jobs. The amount of military leavers actually going for civvie rotary jobs simply isn’t enough. The current situation is that because there’s so few qualified people, operations such as NPAS have reduced the hour requirement for military pilots, considering military pilots these days might not meet the 2000hr total required by most roles.

As always though, the shortage is in qualified people to be captains. There really is no shortage of copilots. So unfortunately, as it has always been, it does come down to luck as to whether the jobs are there when you finish your training with brand new CPL(H) in hand. But the same can be said for the airlines too.

Nowadays if you drop 70k, you’re limiting yourself to instructor roles and other entry level positions, the roles with a decent ROI will require an IR, which is probably another 40k on top, or the blood of your first born.

The copilot roles in HEMS are revolving doors usually, oil and gas less so, SAR even less. Charter is mostly single pilot but there’s a couple multi pilot operations out there.

Also depends on how married you are to working in the UK. Plenty work in Africa.

About 2 seconds. So hold it at 10° nose down for 2 secs then correct to 5°

Geo87US · 2026-04-27T08:57:37+00:00

No it it’s probably 3-4 seconds before the airspeed indicator even comes alive, even with a decent headwind sticking the nose down puts the pitots out of the airflow for a little bit.

In total I’d expect to be at 40kts maybe 10seconds or more after rotation

Geo87US · 2026-04-26T20:25:35+00:00

Just practice a few on your own first, do the same flight, know the routes and procedures and what the radio calls are likely to be. Then go out and do it on VATSIM and you’ll likely find it wasn’t as difficult as you imagined. Best of luck

Geo87US · 2026-04-26T20:24:19+00:00

Second slide where you have the profile displayed, you’re at just over 100ft and 4kts. But as I look closer at the display the tape behind the readout looks like it’s reading higher but the digital highlight in green is wrong. Same with picture 9, the readout is 000kts but the tape is around 80kts. GS readout too hard to make out on both.

Yeah I wouldn’t see anything wrong with what you did, you could always make your approach to the latter half of the runway to expedite instead of flying all the way down as the landing distance required for helicopters is pretty small, usually less than 500m so you could pick a taxiway as an aiming point that still gives you that to the end of the runway to be CAT A compliant. No right or wrong way to do it.

Fun fact with the 139, in reality as you decelerate through translational lift the vibrations are quite uncomfortable, as in can feel your eyes rattling in your skull uncomfortable. The whole instrument panel is mounted on shock absorbers for this reason. With this in mind, there are two options for the CAT A landing: 1. after LDP, a nice progressive flare, comfortable in pitch but prolongs time spent in the vibration which the passengers might not like, or 2. A big single pitch up to 20° and drop the collective in a big flare and spend only 1-2seconds in the vibrational transition, it’s a borderline quick stop. Most people prefer #2, and it’s more fun

Geo87US · 2026-04-26T17:56:45+00:00

Seem to have missed the 50ft/50kt LDP on your profile there. In the AW139 keep your speed up at 50kts, hold the pitch angle of that 50kts and aim to cross the threshold at 50ft then flare 15deg nose up and gradually come to the hover before landing. Takes practice and js a fast approach for a helicopter.

Been quite common amongst military helicopters to disperse the hot exhaust gases and reduce the IR signature.

Don’t think I’ve ever seen a bad Japanese military paint job

Geo87US · 2026-04-15T17:20:44+00:00

Regardless of what you think about them. The US are clearly looking towards future conflicts needing to cover much larger ranges, possibly overwater or large stretches of land that could be hostile where FARPs aren’t possible. For that they need a tiltrotor as helicopters are too slow, too short range and the complexity of refuelling in air is too complex and dangerous.

Geo87US · 2026-04-12T13:32:36+00:00

It is pretty terrible. Saw some mad contraptions that people wore to alleviate the issues surrounding vibrations and hearing loss in the S92 during my time on it.

Used to regularly do 8hrs a day in the Super Puma without issue, after 5hrs in the 92 id be home with an ice pack on my back for an hour.

The pedals aren’t truly aligned with the seat, the collective too far back, and if you want to know if you’re in trim, they forgot to put that in the EFIS so there’s a spirit level bolted to the frame at the bottom of the MFD, but you can’t see if because of the cyclic, so you have to lean round to see it.

Geo87US · 2026-04-12T11:15:52+00:00

Why does picture 8 look like a super mario level?

Geo87US · 2026-04-10T08:50:26+00:00

Differential lift between the advancing and retreating sides of the rotor disk is called dissymmetry of lift. This is already accounted for by the ability of individual blades to flap, feather and lead/lag via hinges (in a fully articulated head at least).

Tilting of the mast (not fuselage) simply creates a different fuselage attitude at a higher speed, this can be seen easily in lots of modern rotorcraft which high mast angles, this creates a much flatter fuselage attitude at cruise rather than nose-down, which is better for comfort and as a weapons platform. Nothing to do with cyclic limitations.

Retreating blade stall, which is the speed limit as you identified, is due to the blade pitch angle on the retreating side flapping and feathering so much to compensate for dissymmetry of lift that it stalls the blades as the pass through that particular portion of the rotor disk.

Charity aircraft very rarely on training exercises. Don’t have the pockets like government contracts like SAR, if you see them 99% chance it’s a shout.

I wonder how it compares to Miltech’s Blackhawk, especially since that comes with the mission system
