So the gage is a suggestion. GREAT!
As is the altimeterâŠ
âThis is your height above sea level, provided you set the local air pressure and that the temperature is according to the international standard atmosphere⊠Good luck!â
And as an addendum:
âOh, and if youâre flying over mountains and itâs windy, you canât really rely on my readings, eitherâ
Thank the maker for radar altimeters.
And GPS with a terrain database!
GPS robbed us of the art of Navigation. The first one i had was a Desert Storm gadget. It gave you coordinates when you locked ot to 3 satellites. You still neede a paper map. LoL
My oh my, times have changed.
In a way it has⊠But we must remember the old ways because GPS is easily jammed.
We see it everytime thereâs a military excercise.
âŠyeahâŠwhen I was flying the Viggen IAS meant more âImpliedââŠsometimes âInsincereââŠair speedâŠjust sayân. 
It is amazing how bad the majority of the military is at land nav. Even units that reallllly ought to be good at it. A good buddy was talking about going through SF selection, and the single biggest wash out factore before you even get into the Q-course propper was land nav. Guys from light infantry and regular infantry units coming in that didnât know pace count, terrain to map association etc. Stuff that 20 years ago was bread and butter of even non-combat arms (you canât setup the field kitchen if you canât get to the right spot). About the only folks that would come through actually were fairly decent on land nav on a regular basis were out of Ranger Battalion or had just finished Ranger school.
GPS is amazing, but when you have guys looking at it to find which was is East as the sun dawns over the horizon you gotta wonder.
Unfortunately I am one of those types who can get lost in my own houseâŠ

What do you mean?
Itâs either SAKTA, FORT or FORTAST. (Slow, Fast, Fastest). 
It is all fun and games until the hastighetsövervakning med laserhastighetsmÀtare gets you.
(One awesome thing the Scandinavian languages have in common with German are the long words).
You mean the grammarrulesallowingforstickingtogetherofrandomstufftomakeoneword? Yeah thatâs a pretty cool thing. That and conjugations and you can write some pretty darn dense and very precise stuff in German.
It isnât strange that Imannuel Kant wrote German, I donât think a Frenchman could have even thought it, simply lacking the words to think it up.
Ephraim Kishon once said in an interview that he likes writing stuff in German because of all the languages he knows (Hebrew, English, Hungarian, German and IIRC a few more) German is the most precise.
(But we are getting off topic)
He was once asked if he could write in another language, to which he replied, âI Kant.â 
By âmilitaryâ I assume you mean ground forces. In the Navy we rarely had need for land nav beyond âdonât try to sail across the landâ âŠusually helpfully annotated on the charts we usedâŠthe ânon-blueâ areas.
That said, and on a more serious noteâŠwhen I was CO of the Navyâs Intel Schoolhouse, we had a course that taught intelligence support to Navy special ops (SEALs). We had an entire section on Land Nav. The section final exercise was to navigate around the Yorktown Battlefield (the entire area is quite big) using just the paper maps, compass and a little plastic overlay grid thingy (for @schurem, in German it is called âDas Littleplasticoverlaythingyâ).
Many decades ago when I was a new grunt, I remember our XO talking about when he was a platoon leader in Vietnam. At night, the fire bases would harass the enemy. Therefore when on patrol, they were required to report their position by 2100. Lt said that he would plot their posit, then have two sgts do the same as a cross check. He said that he did this due to at least once a month hearing on the radio a unit calling in that they were taking friendly fire.
And everyone knows that Froendly Fire isnâtâŠ
I was in the 101st LRSD. Long Range Surveillance Detachement. It was Ft Campbell in the late 90s. We Land Naved in the rain, at night⊠i knew some of the forrest animals by heart. It was all with a map, protractor and terrain association. Now we just switch off our brains and follow the cues.
I can happily still report the Corps is still teaching land nav by hand with the old compass and protractor. Itâs been quite some time now, but Iâm fairly positive the engineer stakes with ammo cans attached to them are still out there in the ranges waiting to be stumbled upon. There was a couple different ways the courses worked. Some gave you a starting position and from there you received direction and distance to the next post and so on. These were a little simpler because there tended to be a trampled trail from one post to the next. The other was a little more difficult. You were handed a sheet with 10-15 different coordinates on it with a blank spot for the âcodeâ at each post. Either inside the ammo can or attached to the stake at the coord was a dog tag stamped with a number. You had to find a certain number of codes to âpassâ. This kind of mission often started by getting a battle buddy and then having a staggered start.
My son was in the 101st from 2014-2017 - his first tour in Afghanistan he did night patrolling outside the wire. He was pretty good at land nav to begin with.
I am very proud of him being in the 101st but never understood the propensity to get out of flying helicopters before they land.
Neither do I; youâre supposed to ride them right into the ground. When the spinny bits stop spinning, you die like real man.
