The 15 kt limit is set by Boeing, which was in place until now. The latest version of the app now allows you to switch between 15 and 20 kt, both of which are limits set by Boeing. ### 3/5 — Crosswind miscalculation *2019-04-15* Shot an approach today into KDEN 35L (351 HDG) Vref 140 winds 260@20G36 according to the app Vapp 145. During an update it now does not add full gust factor anymore for crosswind. No longer complies with Boeing FTM of 1/2 headwind component plus the full gust up to 15 knots (still 20 at some companies). **Developer response:** Thanks for your feedback! Most aircraft models now limit the additive to 15 kt, but we’ve added the option to switch to 20 kt where needed. Plus, the latest update now shows gust values for both headwind and crosswind components, giving you more complete information for your approaches. ### 3/5 — Max wind additive *2019-02-24* The B767 at our company is flown with a max wind additive of 20 knots. (1/2 steady state headwind component plus full gust factor above headwind component) i.e. RWY 36, Vref=135, wind-360/20G40, Vapp should be 155, but the app says 150. This app has the max wind additive at 15 knots. Is there a way to change this to 20 knots? **Developer response:** Thanks for your feedback! Most aircraft models now limit the additive to 15 kt, but we’ve added the option to switch to 20 kt where needed. Plus, the latest update now shows gust values for both headwind and crosswind components, giving you more complete information for your approaches ### 3/5 — WTF metric sys *2017-11-02* Can you make previous metric system. Only wind on metric required, but not VAPP or VREF **Developer response:** Hello, thanks! Please email me at support@cushqui.org to better understand your request. I'd love to get it implemented soon ### 4/5 — Very handy *2019-06-11* It would be nice if there were some option to toggle between the 15 and 20 additive. The new FCTM May say 15, but airlines are slow to actually change the procedure. Flying the 747 and our FCOM and current version of FCTM still shows max of ref and 20. Other than that it’s fantastic. **Developer response:** Thank you for your feedback! We hear you— so the latest version of the app now lets you toggle between 15 and 20 kt. We’re glad you’re enjoying the app otherwise! ### 4/5 — Very nice *2013-08-30* Very useful app nice interface, would like to see the rate of descent with a variable angle ### 4/5 — Aliz *2013-07-23* great app! BUT more could be done like adding takeoff references as well ! ### 5/5 — Супер *2019-04-26* Отлично, очень хорошо помогает в расчетах и экономит время ### 5/5 — Super! *2018-11-08* Easy to use. Super helpful. ### 5/5 — Does calculate tail wind gust correctly *2018-02-26* Changed my review. I was in error. Great app. **Developer response:** Hello, quoting Boeing FCTM B767 Page 1.15: "Note: Do not apply wind additives for steady tailwinds or tailwind gusts. Set command speed at VREF +5 knots (autothrottle connected or disconnected) ## Most praised reviews (7 highest-rated) ### 5/5 — Very Useful! *2018-01-18* Outstanding for precise data verification. Wish numbers were larger, but app is easy to use and very useful under challenging conditions. ### 5/5 — Very *2017-03-13* Goooood! ### 5/5 — Nice! *2016-04-23* Very useful and easy to use. Thanks. ### 5/5 — Cool *2016-01-23* Very helpful....good visualisation ### 5/5 — cool *2015-12-13* ty for realization metric system, its amazing app ### 5/5 — Great tool *2015-12-13* I like to confirm my numbers with this app especially after a long international flight. The B767 SOP requires disconnecting auto thrust so you end up doing the 1/2 headwind plus all...The new metric addition is great for potential Russian diversions & etc. ### 5/5 — Nice *2015-08-14* Very good app!!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
